Irland håber at gå foran med at reducere CO2 -fodaftrykket

Irland håber at gå foran med at reducere CO2 -fodaftrykket

Drivhusgasinitiativer finder sted på Greenhouse Gases and Animal Agriculture -konferencen i Dublin

TEAGASC, den irske landbrugs- og fødevareudviklingsmyndighed ved University College i Dublin, afholder en konference for at fokusere på de stigende drivhusgasemissioner fra dyr. Konferencen skal starte, hvor de slap ved deres sidste møde i 2010, og planlægge, hvordan de kan reducere nogle af disse skadelige gasser.

En konsensus i europæisk energi støttede et nyt mål for reduktion af drivhusgasser (drivhusgasser) i 2030, som rapporteret af UPI i april. Pat Rabbitte, den irske energiminister, sagde, at EU -kommissærens opfordring til en 40 procent reduktion af drivhusgasser i 2030 (startende i 1990) kræver øjeblikkelig handling.

Teagasc rapporterede Dr. omsættes til praksis, ”angående konferencemålene tidligere på måneden.

Fra april blev den procentvise reduktion anslået til 20 procent i 2020 med forventninger til 40 procent i 2030, og EU skal finde opfindelser, der skal bakkes op for at nå dette meget nødvendige mål.


Daglig briefing

Der er udbredt dækning af den seneste "emissionskløft" -rapport fra FNs miljøprogram (UNEP), hvor Washington Post fører den vinkel, at "verdens velhavende skal reducere deres CO2 -fodaftryk med en faktor 30 for at hjælpe med at sætte planet på en vej til at dæmme op for de stadig forværrede virkninger af klimaændringer ”. Det fortsætter: ”I øjeblikket tegner emissionerne sig for de rigeste 1% af den globale befolkning mere end det dobbelte af de fattigste 50%. At ændre balancen, fandt forskere, vil kræve hurtige og betydelige livsstilsændringer. ” BBC News vælger også den linje til at lede sin egen dækning af UNEP -rapporten og siger: ”Deres rapport om emissionskløft viser, at de rigeste hurtigt skal reducere deres CO2 -fodaftryk for at undgå farlig opvarmning i dette århundrede. Undersøgelsen finder, at den globale lukning af Covid-19 vil have lidt langsigtet indvirkning på klimaet. Men en stærk, grøn opsving kan begrænse stigningen i temperaturerne til 2C. Undersøgelsen ... understreger kløften mellem emissionsniveauet i overensstemmelse med at holde temperaturen nede og hvad der sker i den virkelige verden. Det forudsiger, at selvom kulstofproduktionen vil være faldet med omkring 7% i år på grund af pandemien, ville dette kun reducere opvarmningen med 0,01C i 2050. ” The Guardian citerer UNEPs administrerende direktør Inger Andersen: ”Vi går i den forkerte retning. Vi havde lockdown. Nogle mennesker tror, ​​at det gav os en bonanza. Men det gør den ikke. Bare fordi du holder op med at køre vandhanen et øjeblik eller to, ændrer det ikke ved, at badekarret stadig er fyldt. ” New York Times, Independent, Axios og Reuters er blandt de andre forretninger, der dækker rapporten. Carbon Brief har også opsummeret rapporten.

I mellemtiden har Guardian et "eksklusivt" interview med FN's generalsekretær António Guterres, hvor han ifølge avisen siger, at "rige lande vil savne et vigtigt løfte, de gav til den fattige om klimakrisen ved ikke at levere penge, der er nødvendige for, at de kan klare virkningerne, hvilket skader udsigterne til global handling ”.

Hver for sig dækker BusinessGreen BloombergNEFs seneste årlige ClimateScope -rapport, der viser, at "investeringer i ren energi i udviklingslande er blevet forstyrret af pandemien efter at have nået rekordniveauer i 2019". Den tilføjer: "Den seneste udgave af den indflydelsesrige analytikers årlige ClimateScope -undersøgelse afslører, at de samlede udenlandske direkte investeringer i ren energi i udviklingslande ramte 32 mia. Dollar sidste år, da solcelleanlæg og vindmølleparker blev mere og mere konkurrencedygtige i sammenligning med projekter til produktion af fossilt brændsel ... Men , Advarer BloombergNEF om, at investorer i ren energi har haft appetit på projekter på nye markeder, der er blevet bulet af pandemien. ” Bloomberg dækker også historien.

Endelig rapporterer BusinessGreen også om en "større ny undersøgelse" fra konsulentfirmaet Systemiq, der siger, at "nulemissionsteknologier kan 'udkonkurrere' ældre kulstofintensive industrier på tværs af flere sektorer verden over inden for et årti, da investorer, virksomheder, regeringer og forbrugere kræver en skifte mod renere, grønnere løsninger i løbet af 2020’erne ”. Det fortsætter: ”Rapporten med titlen The Paris Effect beskriver, hvor rene og grønne løsninger er på vej til at blive konkurrencedygtige med snavset modparter i sektorer, der tegner sig for over 70% af de globale emissioner inden 2030, hvilket kunne levere en global grøn økonomi, der er i stand til at generere 35m job og et sundere samfund. Fremskrivningerne markerer et betydeligt skift fra fem år siden, da der næsten ikke var nogen grøn konkurrence til fossile brændstoffer overhovedet. ” The Independent dækker også rapporten, mens BBC News har dækning i en bredere funktion med overskriften: "Klimaændringer: Har lande holdt deres løfter?".

Financial Times siger, at en "bred gruppe af kvindelige klimaledere har opfordret FN's klimatopmødeledelse til hurtigst muligt at tage fat på en mangel på kvinder i teamet, der skal styre næste års internationale samtaler i Storbritannien". Det tilføjer: ”Mere end 400 indflydelsesrige kvinder søger ændringer i det mandsdominerede lederskab til FN's klimaforhandlinger, som Storbritannien var vært for i Glasgow, i et åbent brev til premierminister Boris Johnson og forretningssekretæren Alok Sharma. Tungvægtsunderskriverne-herunder medforfatter af Paris-aftalen Laurence Tubiana og Irlands tidligere præsident, Mary Robinson-sagde, at det var afgørende for vellykkede forhandlinger og beslutningstagning, at kvinder blev inkluderet på topniveauer på topmødet, kendt som COP26. FT forklarer, at "selvom 45% af den øverste ledelse i COP26 -enheden er kvinder, er der ifølge regeringen mange i støtte- og kommunikationsstillinger frem for forhandlingsroller". Det fortsætter: ”Seks af de otte mest højtstående medlemmer er mænd - heriblandt den administrerende direktør, Storbritanniens førende klimaforhandler, Storbritanniens COP26 -udsending og COP -præsidenten, efter at Sharma selv afløste tidligere præsident Claire O'Neill, tidligere britisk energiminister , pludselig i februar. ” Solen dækker også historien i sin trykte udgave.

I mellemtiden rapporterer Sky News synspunkterne fra Storbritanniens tidligere klimasekretær, Amber Rudd, der siger, at COP26-formandskabet er så kritisk, at det må blive en fuldtidsrolle. Hun fortæller til tv -stationen: ”Min egen opfattelse er, at den, der er COP’s præsident - og Alok [Sharma] absolut kunne gøre et godt stykke arbejde med dette - ikke skulle gøre andet. Dette er ikke en sidehastighed, det er den vigtigste begivenhed, der finder sted næste år. Vi har ikke råd til at gøre dette til et deltidsjob. ” The Independent rapporterer synspunkterne fra den tidligere amerikanske vicepræsident Al Gore, der har sagt til en online-konference, at COP26 skal markere "en ny æra, hvor menneskeheden endelig går alvorligt ... denne eksistentielle trussel mod vores eksistens".

Reuters siger, at "mennesker rundt om i verden vil have en chance for at overveje reaktioner på klimaændringer under planer om at indkalde til en 'Global Citizens' Assembly 'for at informere [COP26]". Newswire tilføjer: "Projektet globalassemble.org har til formål at bygge videre på lignende initiativer i lande som Irland, Frankrig og Canada, hvor borgerforsamlinger har givet politikere plads til at handle ved at udarbejde ambitiøse forslag om splittende spørgsmål." I avisen siger "det kan betyde en buschauffør fra Storbritannien, en fårebonde fra New Zealand og en fabriksarbejder fra Indien, der alle arbejder sammen om den bedste måde at reducere de globale emissioner".

I andre nyheder med fokus på Storbritannien siger avisen i, at "38 regionale ledere fra Edinburgh til Cornwall forpligter sig til at fjerne drivhusgasemissioner inden 2045-fem år tidligere end målet fra den britiske regering". Og Daily Telegraph rapporterer, at "Boris Johnson har benægtet, at regeringen mangler troværdighed over for klimaændringer i forhold til dens støtte til projekter med fossile brændstoffer i udlandet, da det fremgik, at det tidligere har støttet en lufthavn i Ugandas spirende oliehub med et lån på 240 millioner pund".

Australiens energiminister Angus Taylor har sagt, at landet kunne slå sit mål om at reducere CO2 -emissioner i henhold til Parisaftalen inden 2030 uden at tælle kreditter fra at overopnå sine mål i tidligere klimapagter, rapporterer Reuters. Newswire tilføjer: "Den seneste fremskrivning markerede et skarpt skift for en af ​​verdens største udledere pr. Indbygger og kom forud for FN's klimamotionstopmøde lørdag, femårsdagen for Paris -klimaaftalen i 2015. Australiens politik om at bruge gamle kulstofkreditter til at tælle med til fremtidige emissionsmål var et vigtigt stikpunkt på FN's klimatopmøde for et år siden, da store udledere blev presset til at tage mere aggressiv handling for at dæmme op for den globale opvarmning ... Australiens emissioner forventes nu at blive 29% under 2005 -niveauet i 2030 sammenlignet med sit Paris -aftalemål om at reducere CO2 -emissionerne med 26% til 28%. ” The Guardian siger: “Scott Morrison ønskede at afsløre skiftet på et globalt leders klimateamitionstopmøde i weekenden og telegraferede, at han ville yde et bidrag, men det er fortsat usikkert, om Australien vil få en talerum. Mere end 70 lande havde bekræftet, at vi talte sovepladser onsdag. Selvom det ultimative landingspunkt stadig er uklart, siger de lande, der organiserer topmødet, betydelige forpligtelser, og tætte observatører af klimaforhandlinger har sagt, at de mener, at det er usandsynligt, at Morrison bliver bedt om at tale. ” En anden artikel i Guardian rapporterer, at "EU har opfordret Australien og andre lande til at øge deres forpligtelse til" faktiske emissionsreduktioner "og advarede om, at et forsøg på at stole på overskud opnået i Kyoto -protokolleperioden kan skabe en negativ præcedens". I mellemtiden har New York Times en nyhedsfunktion med overskriften: ”Det er Australiens første store flamme i brandsæsonen. Hvor slem bliver sommeren? ”

Særligt dækker Guardian en ny Oxfam -rapport, der siger "New Zealand lever ikke op til sine løfter om klimaændringer, når det kommer til at hjælpe med at finansiere fattigere lande med at tilpasse sig en opvarmende verden".

Brasilien har meddelt, at det vil sigte mod CO2 -neutralitet i 2060, hvilket ifølge Climate Home News "udløser vrede blandt kampagnerne, der siger, at løftet er meningsløst og en bevidst distraktion fra præsident Jair Bolsonaros ødelæggelse af Amazonas regnskov". CHN tilføjer: "Brasilien annoncerede det 'vejledende' mål i en opdateret indsendelse til FN onsdag, men matchede det ikke med øget ambition i det kommende årti. Målene om at reducere emissionerne 37% inden 2025 og 43% i 2030 i forhold til 2005 -niveauet er uændrede. ” Bloomberg siger: "Brasilien vil sætte et nyt mål om at nulstille kuldioxidemissioner inden 2060 - eller før, hvis det kan rejse 10 mia. Dollars om året fra andre lande."

Reuters rapporterer, at "New York-statens pensionsfond [har] forpligtet sig til at hjælpe med at dæmme op for klimaændringer ved at overføre sine investeringer til drivhusgasemissioner uden nul i 2040, hvilket gør det til den første amerikanske pensionskasse, der har sat målet inden denne dato". Newswire tilføjer: “Statskontroller i New York, Thomas DiNapoli, sagde, at dette skridt vil bringe fonden, den tredjestørste i landet, i en stærk position for fremtiden for en grøn økonomi, der er kortlagt i Parisaftalen om klimaet i 2015 ... New York staten Common Retirement Fund, der har en estimeret værdiansættelse på omkring $ 226 mia., er ved at afslutte sin vurdering af ni oliesandvirksomheder, hovedsageligt i Canada og Rusland, og vil udvikle minimumsstandarder for investeringer i skiferolie og gas. ” Axios siger, at "forslaget fra Amerikas tredjestørste offentlige pensionskasse er et af de mere betydningsfulde skridt i frasalgskampen, der er bygget i løbet af de sidste flere år". New York Times dækker historien og indeholder også et kommentarfelt af veteran klimakampagnen og forfatteren Bill McKibben, der siger: ”Det er naturligvis en kæmpe gevinst for aktivisterne, der har kæmpet i otte år for at få Albany til at frasælge fossile brændstofselskaber og til den globale frasalgskampagne. Legater og porteføljer til en værdi af mere end 14 billioner dollars har sluttet sig til kampen ... Men det repræsenterer også noget andet: kapitulationer, der tilsammen tyder på, at den engang dominerende fossile brændstofindustri har nået et lavt niveau i finansiel og politisk magt. ”

Kommentar.

New York Times har et langt illustreret indslag om, hvordan "Californiens redwoods, sequoias og Joshua -træer, [som] definerer det amerikanske vest og naturens modstandsdygtighed gennem tiderne" i år har lidt under deres "dødeligste test" - naturbrande, der er antændt af klimaforandringer . Artiklen siger: “De brande, der brændte mere end fire millioner hektar i Californien i år, var både historiske og profetiske og varslede en fremtid med mere varme, flere brande og mere ødelæggelse. Blandt ofrene er der i år og i de kommende år mange af Californiens ældste og mest majestætiske træer, der allerede er i begrænset udbud. I vidt forskellige dele af staten, i ikke -relaterede økosystemer adskilt af flere hundrede kilometer, drager forskere den samme konklusion: Hvis de sidste par års brande var en erklæring om klimaændringer, var 2020 udråbstegnet. ”

I et særskilt kommentarfelt i New York Times skriver havforsker Fabien Cousteau: ”Mange af os har oplevet havets magi og skønhed. Men dens vitale forbindelse til vores daglige liv-måderne, hvorpå den leverer ilt, vi indånder og nærer de afgrøder, vi spiser-er langt mindre forstået ... Ligesom min bedstefar, Jacques-Yves Cousteau, tror jeg på, at vi beskytter det, vi elsker, og elsker hvad vi forstår. Vi har evnen til at diktere omfanget af coronavirus og klimakriser, hvis vi blot kan absorbere videnskabens lektioner, herunder den hårde sandhed, at ødelæggelser venter på, hvis vi handler for sent. Vi må lære, at det at være på naturens side er at være på menneskehedens side. ”

Og Maria Fernanda Espinosa - en ecuadoriansk politiker og diplomat og en tidligere præsident for FN's generalforsamling - skriver i Guardian og forklarer, hvorfor "klimakrisen skulle være kernen i den globale genopretning af Covid".

Daily Mail's Stephen Glover raser mod Climate Change Committee's seneste rapport, der råder den britiske regering til at reducere landets emissioner 78% inden 2035 (som rapporteret i går detaljeret af Carbon Brief). Klummeskribenten siger: ”Jeg tror, ​​de fleste mennesker er parate til at tage klimaændringer alvorligt, selvom de skal mindes om, at Storbritannien tegner sig for mindre end 1% af alle drivhusgasemissioner, og at dette lands smertefulde ofre ikke vil gøre stor indflydelse globalt. Det, de ikke sætter pris på, er at blive instrueret i at bruge store summer til en usikker sag af rige mennesker, der arbejder for en skyggefuld og uberegnelig quango, der er skyld i ranghykleri. ” Klimaskeptisk klummeskribent Ross Clark, der skrev i Daily Telegraph, indtager en lignende tone og siger: ”Det er let at sætte mål, en helt anden at komme med praktiske foranstaltninger til at implementere dem til rimelige omkostninger og uden at skade bivirkninger. CCC er meget begejstret for førstnævnte, mens den ikke gør meget for at bevise, at den har opnået sidstnævnte. ” City AM bærer en kommentar af Anthony Catachanas, administrerende direktør for Victory Hill Capital Group - et specialiseret investeringsselskab, der fokuserer på global energiinfrastruktur. Han skriver: "Storslåede planer om en grøn revolution er store, men lad os først ordne vores ældningsnetværk."

Videnskab.

Ny forskning ser på alternativer til at anvende en ensartet kulstofpris - en fast afgift pr. Ton CO2 -emissioner - som en måde at nå Paris -aftalens formildende mål på. Forfatterne viser, at "en strategi for internationale finansielle overførsler styret af moderate afvigelser fra ensartede kulstofpriser kunne nå målet uden at belaste hverken økonomier eller suverænitet i nationer". En ledsagende artikel i News & amp Views siger, at undersøgelsen indikerer "at små afvigelser fra en globalt ensartet kulstofpris kan nå 2C -målet med lidt højere afbødningsomkostninger, men meget lavere overførsler". At reducere økonomiske overførsler til fattigere lande er "politisk gavnligt", siger forfatterne, "fordi de nogle gange opfatter en stor afhængighed af international finansiel overførsel som en underminering af deres nationale suverænitet".


Sådan reduceres miljøpåvirkningen af ​​dit næste virtuelle møde

Inden du kæmper for at rense dit værelse eller forsøger at få din pyjamas til at ligne lidt mere pyjamas, er her en god undskyldning for at holde din video slukket under dit næste virtuelle møde: reducere din miljøpåvirkning. Ny forskning viser, at hvis du slukker for dit kamera under en videokonference, kan du reducere dit miljøaftryk i mødet med 96 procent.

Undersøgelsen blev gennemført af et team fra MIT, Purdue University og Yale University og afdækker de virkninger, som internetbrug har på miljøet. Dette er især vigtigt i betragtning af, at mange lande har rapporteret mindst en 20 procent stigning i internetforbruget siden marts 2020 på grund af Covid-19-nedlukninger.

Selvom skiftet til en mere digital verden generelt har gjort et imponerende indhug i de globale emissioner - hovedsagelig takket være de sandsynlige midlertidige emissionsreduktioner i forbindelse med rejser - bør virkningen af ​​vores stadig mere virtuelle livsstil ikke overses.

"Målet med dette papir er at øge bevidstheden," siger Maryam Arbabzadeh, en postdoc ved MIT Energy Initiative og medforfatter af undersøgelsen. ”Det er fantastisk, at vi reducerer emissioner i nogle sektorer, men samtidig har brug af internettet også en miljøpåvirkning, der bidrager til aggregatet. Den elektricitet, der bruges til at drive internettet med dets tilhørende kulstof-, vand- og landaftryk, er ikke det eneste, der påvirker miljøet, og transmission og lagring af data kræver også vand for at afkøle systemerne i dem. ”

En times streaming eller videokonference kan udsende mellem 150 og 1.000 gram kuldioxid afhængigt af tjenesten. Til sammenligning producerer en bil omkring 8.887 gram ved at brænde en gallon benzin. Den time kræver også 2-12 liter vand og et areal på størrelse med en iPad Mini. Disse timer tilføjer i vores daglige liv med al den tid, vi bruger på video - og det samme gør det tilhørende miljøaftryk.

Ifølge forskerne, hvis fjernarbejde fortsætter i slutningen af ​​2021, kan det globale CO2 -fodaftryk vokse med 34,3 millioner tons i drivhusgasemissioner. For at give en fornemmelse af omfanget: Denne stigning i emissioner ville kræve en skov, der er dobbelt så stor som Portugal, for fuldt ud at binde det hele. I mellemtiden ville det tilhørende vandaftryk være nok til at fylde mere end 300.000 olympiske svømmebassiner, og landets fodaftryk ville være stort set på størrelse med Los Angeles.

For at gemme og overføre alle de data, der driver internettet, bruger datacentre strøm nok til at tegne sig for 1 procent af det globale energibehov - hvilket er mere end det samlede forbrug i mange lande. Selv før pandemien havde internettets kulstofaftryk været stigende og tegnede sig for omkring 3,7 procent af de globale drivhusgasemissioner.

Selvom der har været undersøgelser, der har vurderet CO2 -fodaftrykket ved internetdatatransmission, lagring og brug, er de tilhørende vand- og landaftryk stort set blevet overset. For at afhjælpe dette hul analyserer forskerne i denne undersøgelse de tre store miljømæssige fodaftryk - vand, jord og kulstof - som de vedrører internetbrug og infrastruktur, hvilket giver et mere holistisk kig på miljøpåvirkningen. Deres resultater offentliggøres i Ressourcer, bevarelse og genbrug.

Ved hjælp af offentligt tilgængelige data giver forskerne et groft skøn over kulstof-, vand- og landaftryk forbundet med hver gigabyte data, der bruges i almindelige online -apps som Netflix, Instagram, TikTok, Zoom og 14 andre platforme samt generelt websurfing og online spil. De finder ud af, at jo mere video der bruges, jo højere fodaftryk.

En almindelig streamingtjeneste, som Netflix eller Hulu, kræver 7 gigabyte pr. Time videostreaming i høj kvalitet, hvilket i gennemsnit oversætter til 441 g CO2e (gram pr. kuldioxidækvivalent) pr. time. Hvis nogen streamer i fire timer om dagen med denne kvalitet i en måned, stiger emissionerne til 53 kg CO2e. Men hvis denne person i stedet skulle streame i standard definition, ville det månedlige fodaftryk kun være 2,5 kg CO2e. Denne beslutning ville spare emissioner svarende til at køre bil fra Baltimore, Maryland til Philadelphia, Pennsylvania, cirka 93 miles.

Multiplicer nu disse besparelser på tværs af 70 millioner brugere, der alle streamer i standard definition frem for high definition. Denne adfærdsændring ville resultere i et fald på 3,5 millioner tons CO2e - svarende til eliminering af 1,7 millioner tons kul, hvilket er cirka 6% af det samlede månedlige forbrug af kul i USA.

”Banksystemer fortæller dig den positive miljøpåvirkning ved at gå papirløs, men ingen fortæller dig fordelen ved at slukke dit kamera eller reducere din streamingkvalitet. Så uden dit samtykke øger disse platforme dit miljømæssige fodaftryk, ”siger Kaveh Madan, der ledede og ledede denne undersøgelse, mens han var på besøg hos Yale MacMillan Center.

Mens mange tjenesteudbydere og datacentre har arbejdet på at forbedre driftseffektiviteten og reducere deres CO2 -fodaftryk ved at diversificere deres energiporteføljer, skal der stadig træffes foranstaltninger for at reducere produktets fodaftryk. En streamingtjenestes videokvalitet er en af ​​de største afgørende faktorer for dens miljømæssige fodaftryk. I øjeblikket er standard for mange tjenester high-definition, hvilket påhviler brugeren at reducere kvaliteten af ​​deres video for at forbedre deres fodaftryk. Ikke mange mennesker vil være interesserede i at reducere deres videokvalitet, især hvis fordelene ved denne handling ikke er velkendte.

"Vi har brug for virksomheder til at give brugerne mulighed for at træffe informerede, bæredygtige valg," siger Arbabzadeh. ”Virksomheder kan ændre deres standardhandlinger for at føre til mindre miljøbelastning, f.eks. At indstille videokvalitet til standarddefinition og give brugerne mulighed for at opgradere til high definition. Dette vil også kræve, at beslutningstagere inddrages - ved at vedtage regler og kræve gennemsigtighed om digitale produkters miljøaftryk for at tilskynde både virksomheder og brugere til at foretage disse ændringer. ”

Forskerne ser også på bestemte lande for at forstå, hvordan forskellige energisystemer påvirker miljøfodsporene for en gennemsnitlig energienhed, der bruges til databehandling og transmission. Dataene viser stor variation i kulstof-, land- og vandintensitet. I USA, hvor naturgas og kul udgør den største andel af elproduktionen, er kulstofaftrykket 9 procent højere end verdens median, men vandets fodaftryk er 45 procent lavere, og landaftrykket er 58 procent lavere. I mellemtiden, i Brasilien, hvor næsten 70 procent af elektriciteten kommer fra vandkraft, er det mediane CO2 -fodaftryk omkring 68 procent lavere end verdensmedianen. Vandfodaftrykket derimod er 210 procent højere end verdens median, og stigende afhængighed af vandkraft på bekostning af skrøbelige regnskovsøkosystemer har andre betydelige miljøomkostninger.

"Alle disse sektorer er relateret til hinanden," siger Arbabzadeh. "I datacentre, hvor elektricitet kommer fra en renere kilde, vil emissionerne være lavere, og hvis det kommer fra fossile brændstoffer, vil virkningen være større."

”Lige nu har vi virtuelle møder overalt, og vi bruger mere af vores fritid end nogensinde på at streame videoindhold. Der er helt sikkert et paradigmeskifte, «tilføjer hun. ”Med nogle små adfærdsændringer, f.eks. Afmelding af uønskede e -mails eller reducering af lagring i skyen, kan vi have indflydelse på emissionerne. Det er vigtigt, at vi øger offentlighedens bevidsthed, så vi i fællesskab kan gennemføre meningsfulde personlige og systemiske ændringer for at reducere internettets miljøpåvirkning og med succes overgå til en lavemissionsøkonomi. ”

Undersøgelsen blev støttet af MIT Energy Initiative, Purdue Climate Change Research Center, Purdue Center for the Environment og Yale MacMillan Center.


Crypto og blockchain skal acceptere, at de har et problem og derefter føre til bæredygtighed

Da prisen på bitcoin når rekordhøjder og kryptokurver bliver mere og mere mainstream, bliver branchens voksende CO2 -fodaftryk sværere at ignorere.

Bare i sidste uge meddelte Elon Musk, at Tesla suspenderer køretøjskøb ved hjælp af bitcoin på grund af miljøpåvirkningen af ​​fossile brændstoffer, der bruges i bitcoin -minedrift. Vi bifalder denne beslutning, og den bringer lyset af situationens sværhedsgrad frem, og industrien har brug for at håndtere kryptobæredygtighed nu eller risikere at hindre kryptoinnovation og fremskridt.

Markedsværdien af ​​bitcoin i dag er hele $ 1 billion. Da virksomheder som PayPal, Visa og Square i fællesskab investerer milliarder i krypto, skal markedsdeltagere gå forrest i at reducere branchens kollektive miljøpåvirkning dramatisk.

Den stigende efterspørgsel efter krypto betyder skærpet konkurrence og større energiforbrug blandt minedriftsoperatører. For eksempel oplevede vi i løbet af anden halvdel af februar, at elforbruget i BTC steg med mere end 163% — fra 265 TWh til 433 TWh —, da prisen skød i vejret.

Bæredygtighed er blevet et emne for bekymring på dagsordener for globale og lokale ledere. Biden -administrationen, der sluttede sig til Paris -klimaaftalen, var den første indikation på dette, og for nylig har vi set flere føderale og statslige agenturer komme med erklæringer, der viser, hvor meget en prioritet det vil være at håndtere den globale klimakrise.

Et foreslået New York -lovforslag har til formål at forbyde kryptominingcentre at operere, indtil staten kan vurdere deres fulde miljøpåvirkning. Tidligere på året fremsatte den amerikanske Securities and Exchange Commission en opfordring til offentlig kommentar om klimaoplysninger, da aktionærerne i stigende grad ønsker oplysninger om, hvad virksomheder gør i denne henseende, mens finansminister Janet Yellen advarede om, at mængden af ​​energi, der forbruges ved behandling af bitcoin, er "Svimlende." Storbritannien annoncerede planer om at reducere drivhusgasemissioner med mindst 68% inden 2030, og premierministeren lancerede sidste år en ambitiøs plan for en grøn industriel revolution.

Crypto er kommet for at blive — dette punkt er ikke længere til debat. Det skaber virkelige fordele for både virksomheder og forbrugere — fordele som hurtigere, mere pålidelige og billigere transaktioner med større gennemsigtighed end nogensinde før. Men efterhånden som industrien modnes, skal bæredygtighed stå i centrum. Det er lettere at opbygge et mere bæredygtigt økosystem nu end at "reverse engineer" det på et senere vækststadium. Dem på kryptokurrencymarkederne bør overveje bilindustrien som en kanariefugl: Carmakers eftermonterer nu lavere kulstof- og kulstofneutrale løsninger til store omkostninger og gener.

Markedsdeltagere skal aktivt arbejde sammen om at realisere en fremtid med lave emissioner drevet af ren, vedvarende energi. I sidste måned blev Crypto Climate Accord (CCA) lanceret med over 40 tilhængere — inklusive Ripple, World Economic Forum, Energy Web Foundation, Rocky Mountain Institute og ConsenSys — og målet om at gøre det muligt for alle verdens blockchains at blive drevet med 100% vedvarende energi i 2025.

Nogle branchedeltagere undersøger vedvarende energiløsninger, men den større industri har stadig en lang vej at gå. Mens 76% af hasherne hævder, at de bruger vedvarende energi til at drive deres aktiviteter, kommer kun 39% af hashens samlede energiforbrug fra vedvarende energi.

For at få en meningsfuld indvirkning skal industrien komme med en standard, der er åben og gennemsigtig for at måle brugen af ​​vedvarende energi og gøre vedvarende energi tilgængelig og billig for minearbejdere. CCA arbejder allerede på en sådan standard. Derudover kan virksomheder betale for højkvalitets kulstofudligninger for resterende emissioner og#8212 og måske endda historiske.

Mens industrien arbejder på at blive mere bæredygtig på lang sigt, er der grønne valg, der kan træffes nu, og nogle branchespillere hopper om bord. Fintechs som Stripe har skabt kulstoffornyelsesprogrammer for at tilskynde sine kunder og partnere til at være mere bæredygtige.

Virksomheder kan indgå partnerskaber med organisationer, f.eks. Energy Web Foundation og Renewable Energy Business Alliance, for at frigøre kulstof nogen blockchain. Der er ressourcer til dem, der ønsker at få adgang til vedvarende energikilder og CO2-kompensationer af høj kvalitet. Andre muligheder omfatter brug af iboende kulstoffattige teknologier, som XRP Ledger, der ikke er afhængige af proof-of-work (som involverer minedrift) for at hjælpe med at reducere emissioner betydeligt for blokkæder og kryptofinansiering.

XRP Ledger er kulstofneutral og bruger en validerings- og sikkerhedsalgoritme kaldet Federated Consensus, der er cirka 120.000 gange mere energieffektiv end proof-of-work. Ethereum, den næststørste blockchain, overgår fra proof-of-work til en langt mindre energikrævende valideringsmekanisme kaldet proof-of-stake. Proof-of-work-systemer er ineffektive af design og vil som sådan altid kræve mere energi for at opretholde fremskridt.

Klimaændringernes ødelæggende virkning bevæger sig i en alarmerende hastighed. At gøre ambitiøse forpligtelser til bæredygtighed — eller værre, at benægte problemet — er ikke nok. Som med Paris -aftalen har industrien brug for reelle mål, kollektiv indsats, innovation og fælles ansvarlighed.

Den gode nyhed? Løsninger kan være praktiske, markedsdrevne og skabe værdi og vækst for alle. Sammen med klimaforkæmpere, ledere inden for ren techindustri og globale beslutningstagere inden for finansiering kan krypto forene sig om at positionere blockchain som den mest bæredygtige vej fremad i skabelsen af ​​en grøn, digital finansiel fremtid.


Hvordan Hilton skærer sit miljømæssige fodaftryk til det halve

I 2018 annoncerede Hilton, at det vil reducere sit miljømæssige fodaftryk til det halve og fordoble sin investering i social indvirkning inden 2030. Et år senere giver Senior Director of Responsibility Daniella Foster en vis indsigt i, hvordan brandet arbejder hen imod dette mål.

Looking at New York City alone where Hilton has an array of properties, catering to different clienteles, from those paying $150 per night to more luxurious rooms that start at more than $500 a night, the global hospitality brand is adapting its sustainability practices for these very different, and often massive, properties.

Diarmuid Dwyer, for instance, is the General Manager at the Hilton Midtown, the largest hotel in New York City, and the largest Hilton in the continental US. With nearly 2,000 rooms and over 150,000 square feet of meeting place, this hotel is the perfect testing ground for Hilton's environmental goals. Dwyer breaks down how the hotel is slowly cutting back on its energy consumption and eliminating waste.

Esha Chhabra: In 2018, Hilton launched its Travel with Purpose 2030 Goals . Given Hilton's desire to cut down its carbon footprint, what is the company doing to achieve those goals and what kind of progress has been made?

Daniella Foster: Through these goals, Hilton is, as stated, committed to cut its environmental footprint in half and double its social impact investment. The company also became the first major hotel company to set approved science-based targets in line with the Paris Climate Agreement to reduce carbon emissions and will be the first to adopt a global standard for sustainable tourism.

Many of the 2030 goals represent huge initiatives: reducing water consumption and waste output by 50%, creating economic opportunities to support women, helping hard-to-reach youth find fulfilling careers and more. However, much like the hospitality industry, Hilton also focused on the details that can make all the difference, including sending zero soap to landfill. The company is already making incredible progress on its 2030 goals, and is committed to publishing its progress annually in the Corporate Responsibility report.

In order to track our progress, Hilton uses LightStay, a corporate responsibility measurement system to calculate, analyze and report the environmental and social impact at each of Hilton’s more than 5,700 hotels.

Chhabra: At the Hilton Midtown in New York, for example, I noticed the following: disposable cups being sent to rooms, plastic packaging, chemical-based cleaners being used by housekeeping, and single-use toiletries. Are these the kinds of things that the hotel would transition away from?

Foster: As part of our 2030 goals, Hilton has reduced our waste to landfill by 41% across our global portfolio, with a focus on improving recycling rates and reducing food waste and plastics usage at our hotels. We expanded our soap and amenity bottle recycling program to over 75% of our hotels, set a new brand standard to remove plastic straws, stir sticks and cocktail picks from all hotel operations and launched regional Plastics Reduction Task Forces to identify opportunities to reduce single-use plastics in our properties. The launch of our new food waste program has also contributed to our waste reduction.

Chhabra: Hilton Midtown is a massive operation. So how does the General Manager approach these issues of sustainability when there's a mix of clientele with different expectations from business travelers to folks on holiday?

Diarmuid Dwyer: Last year, Hilton asked 72,000 guests about their buying preferences and learned social, environmental and ethical considerations are important, especially to younger travelers who spend over $400 billion USD annually on travel. One-third of those surveyed said they actively seek information on a hotel company’s sustainability practices before booking, with nearly two-thirds saying they conduct research even if the information is not easily accessible. In an earlier survey, 60% of guests said a company’s environment and social efforts would have an increased impact on their booking decisions over the next 12 months.

While this information is more likely to be sought out by leisure travelers than business travelers (36% compared to 29%), both audiences are interested in how hotels are impacting the environment.

Our location lends unique opportunities for innovative endeavors. Due to a decreased local habitat, we’ve designated 16,000 square feet on the fifth-floor rooftop to house nearly half a million honey bees. We’ve also installed a rooftop cogeneration plant that provides clean electricity and heat to the building. This alone reduces our carbon footprint by 30% annually, producing 50% of the electricity needed, and 25% of the steam demand for our nearly 2,000 guest rooms.

Chhabra: Given the scale of the company, with so many large properties around the world, how will this transition to a more eco-friendly future take place? In small doses? Or in one fell swoop?

Foster: Often we pilot eco-friendly practices at our properties prior to rolling out across the enterprise. For example, one of our properties in Hawaii, Hilton Waikoloa Village, was the first to eliminate plastic straws in February 2018. Hilton recognizes that no one property or company can change the world on its own. The only way to truly move the needle is to work together. We are looking to eliminate straws from across all 5,700 of our properties this July.

We will continue to take these best practices and roll out across our hotels, similarly to how soap recycling became a brand standard across our Embassy Suites by Hilton, Hilton Garden Inn, Hampton by Hilton, Homewood Suites by Hilton and Home2 Suites by Hilton brands.

Chhabra: Do the various brands within Hilton talk to each other? Would a more traditional property like Midtown be interacting with the Conrad in the city and learning from each other or do they operate primarily on their own properties?

Dwyer: Hilton properties share best eco-friendly practices not only on the island of Manhattan, but internationally and across all brands. New York City is a masterful microcosm of the American economy, regularly facing concerns before they hit smaller markets, especially issues that directly involve travel and tourism. We are often looked at to lead by example when it comes to pollution and waste in the hospitality industry. I’m proud to be part of the local communal cognizance that lowers our global carbon footprint and contributes to our sustainable economic growth.

Chhabra: What's the most challenging aspect of becoming more eco-friendly?

Foster: As a global company with more than 5,700 properties across the world, mobilizing our global operations and guests around our 2030 Goals takes time. For example, last year, we also announced Connected Room, a high-tech guest room that enables guests to personalize and control every aspect of their stay from their mobile devices. The technology gives guests the option to help conserve energy by syncing the air conditioning with their schedule and allow hotel operators to monitor how their hotels are managing energy in real-time to ensure they are effectively reducing environmental impact. Hilton currently has more than 3,500 Connected Rooms across 15 hotels and plans to roll out the technology to tens of thousands more rooms across hundreds of hotels in the United States.

Virgin Media Ireland signs new Low Carbon Pledge

Virgin’s ongoing initiatives are enabling Virgin Media to improve the environmental footprint of its network while also launching new products, increasing broadband speeds and exponential customer demand for data, where Virgin Media has expanded its gigabit network to just under one million homes in Ireland to date.

In today’s renewed Low Carbon Pledge, Virgin Media has committed to further recording and reducing their entire carbon footprint, both direct (from operations) and indirect emissions (through the supply chain) and reporting regularly on progress including through an annual Business in the Community Ireland Low Carbon Report. This will be reviewed and evolved on an ongoing basis, aligned to the latest climate science and Ireland’s climate action objectives.

“We at Virgin Media are delighted to be signing up to this renewed low carbon pledge supporting Ireland’s climate action objectives” said Peter McCarthy, Vice-President of Legal & Corporate Affairs, Virgin Media. “Virgin Media are actively engaging our business, operations, people and brand to create positive impacts for our customers, people and communities throughout Ireland and for the planet we all depend on for our wellbeing. Our target is to reduce our carbon footprint by 50% by 2025. We believe we will smash that target as we have already seen a reduction of nearly 30% since 2017 through such initiatives as a 100% switch to renewable energy, deploying solar energy panels across key sites and technical hubs, more energy efficient consumer hardware, improved data centre cooling systems and the commencement of electrification of the company’s vehicle fleet. Other areas include gradually removing non-eco consumables from the supply chain and continuing to offer products and experiences that use less power, reduce emissions, and cut down on waste.”

Tomás Sercovich, CEO of Business in the Community Ireland (BITCI), added that climate action is a key priority for BITCI and its members and that having over 60 signatories who have signed up to the Low Carbon Pledge is a clear demonstration of the business community working together to lead to the net zero vision.

Last week, Virgin Media’s parent company Liberty Global (“Liberty Global”) (NASDAQ: LBTYA, LBTYB and LBTYK), one of the world’s leading converged video, broadband and communications companies, further demonstrated its commitment to sustainability by signing on as a founding member of the European Green Digital Coalition.

The coalition has been set up by the European Union to support the use of digital technologies as a key enabler for climate action, environmental sustainability and helping to reach UN Sustainable Development Goals. The founding members were announced by EU Commissioner Thierry Breton and the EU Presidency at the Digital Day 2021 event held in Lisbon, Portugal. By signing the European Green Digital Declaration, companies commit to establishing science-based targets to reduce greenhouse gas (GHG) emissions by 2030 and becoming climate neutral no later than 2040.


Endemol Shine UK to lead on reducing carbon footprint

Endemol Shine UK, working with BAFTA’s sustainability consortium Albert, has committed to training its entire workforce on effective ways to reduce carbon emissions.

It will be the first independent production group to train its entire staff using the specially designed training course from Albert to “marry specific information around climate change with practical ways of evaluating and reducing emissions.”

The course will provide staff with ideas and inspiration on how they can change working practices across the whole production process, and beyond, to further reduce carbon emissions in the work we do.

Endemol Shine UK HR and operations direction Bella Lambourne said: “I cannot think of anything more crucial to train our staff in.

“Our ambition is to ensure that the environmental impact of the decisions we make, both in the work we do and in our daily lives, is front of mind at all times and that we make positive, impactful change in every way we can across the whole business.”

The bespoke training will also consider how we communicate these issues and ideas within the programmes we make, in order to inspire as wide a change as possible.

It will be rolled out to over 600 staff including full time and freelancers, starting in early March.

Endemol Shine UK has worked closely as a consortium member of Albert since it was launched by BAFTA in 2011 to certify that our productions are working hard to reduce carbon emissions, and this latest initiative ties in with Endemol Shine’s overall commitments to sustainability and reducing single-use plastic across the group.

BAFTA head if industry sustainability Aaron Matthews said: “It’s fantastic that Endemol Shine UK is committing to training all its staff.

“Through experience, we know that our training provides the perfect platform to empower a production team.

“Providing them with the specific knowledge and tools they need to make meaningful changes to their working ways and reduce their impact.”


FACT SHEET: Reducing Greenhouse Gas Emissions in the Federal Government and Across the Supply Chain

The President is committed to addressing the climate change threat &ndash both by taking action here at home and showing leadership on the world stage. As part of his commitment to lead by example to curb the emissions that are driving climate change, today President Obama will issue an Executive Order that will cut the Federal Government&rsquos greenhouse gas (GHG) emissions 40 percent over the next decade from 2008 levels -- saving taxpayers up to $18 billion in avoided energy costs -- and increase the share of electricity the Federal Government consumes from renewable sources to 30 percent. Complementing this effort, several major Federal suppliers are announcing commitments to cut their own GHG emissions. Today, the Administration is hosting a roundtable that will bring some of these large Federal suppliers together to discuss the benefits of their GHG reduction targets or to make their first-ever corporate commitments to disclose emissions and set new reduction goals.

Together, the combined results of the Federal Government actions and new supplier commitments will reduce GHG emissions by 26 million metric tons by 2025 from 2008 levels, the equivalent of taking nearly 5.5 million cars off the road for a year. And to encourage continued progress across the Federal supply chain, the Administration is releasing a new scorecard to publicly track self-reported emissions disclosure and progress for all major Federal suppliers, who together represent more than $187 billion in Federal spending and account for more than 40 percent of all Federal contract dollars.

Since the Federal Government is the single largest consumer of energy in the Nation, Federal emissions reductions and progress across the supply chain will have broad impacts. The new commitments announced today support the United States&rsquo international commitment to cut net GHG emissions 26-28 percent below 2005 levels by 2025, which President Obama first announced in November 2014 as part of an historic agreement with China. Additionally, the goals build on the strong progress made by Federal agencies during the first six years of the Administration under President Obama&rsquos 2009 Executive Order on Federal Leadership on Environmental, Energy and Economic Performance, including reducing Federal GHG emissions by 17 percent &mdash which helped Federal agencies avoid $1.8 billion in cumulative energy costs &mdash and increasing the share of renewable energy consumption to 9 percent.

Leading by example in the Federal Government

With a footprint that includes 360,000 buildings, 650,000 fleet vehicles, and $445 billion spent annually on goods and services, the Federal Government&rsquos actions to reduce pollution, support renewable energy, and operate more efficiently can make a significant impact on national emissions. The President&rsquos action today will build on the Federal Government&rsquos significant progress in reducing emissions to drive further sustainability actions through the next decade. In addition to cutting emissions and increasing the use of renewable energy, the Executive Order outlines a number of additional measures to make the Federal Government&rsquos operations more sustainable, efficient and energy-secure while saving taxpayer dollars. Specifically, the Executive Order directs Federal agencies to:

  • Ensure 25 percent of their total energy (electric and thermal) consumption is from clean energy sources by 2025.
  • Reduce energy use in Federal buildings by 2.5 percent per year between 2015 and 2025.
  • Reduce per-mile GHG emissions from Federal fleets by 30 percent from 2014 levels by 2025, and increase the percentage of zero emission and plug in hybrid vehicles in Federal fleets.
  • Reduce water intensity in Federal buildings by 2 percent per year through 2025.

Encouraging progress across the supply chain

In addition to setting aggressive new efficiency standards for Federal agencies, the Administration is engaging with major Federal suppliers to encourage them to adopt similar practices. Today, the Administration is hosting a roundtable that will bring some of the largest Federal suppliers together to discuss the benefits of their GHG emission reduction targets or to make their first-ever corporate commitments to disclose emissions and set new reduction goals. The companies attending this roundtable each do more than $1 billion a year in business with the U.S. Government and together account for about $45 billion in Federal contract spending. Combined, they bring a total GHG reduction commitment of 5 million metric tons between 2008 and 2020, and have made the following specific commitments:

IBM
IBM, one of the world&rsquos largest providers of IT services and solutions, today announced two new goals:

  • Reduce CO2 emissions associated with IBM's energy consumption 35 percent by year-end 2020 against base year 2005 adjusted for acquisitions and divestitures. This represents an additional 20 percent reduction from year-end 2012 to year-end 2020 over the reductions achieved from 2005 to 2012 under the company&rsquos second generation goal.
  • Procure electricity from renewable sources for 20 percent of IBM's annual electricity consumption by 2020. IBM will contract over 800,000 megawatt-hours per year of renewable electricity -- an amount that can power a city of 100,000 people. The company will match its purchased renewable electricity directly to its operations as opposed to purchasing renewable energy certificates as offsets, making a clear connection between purchases and consumption.

IBM has been working on reducing GHG emissions and reporting results for 25 years, avoiding 3 million metric tons of CO2 emissions through conservation actions between 1990 and 2005 -- an amount equal to 40 percent of its 1990 emissions. With today&rsquos announcement, IBM is embarking on its third generation goal.

GE
GE, a global infrastructure and finance company, launched a line of environmentally responsible products in 2005 to accelerate innovation and growth in a resource constrained world through efficient and intelligent solutions. By the end of 2014, GE had invested $15 billion in R&D to develop more efficient technologies and generated approximately $200 billion in revenue from these products. In addition GE committed in 2005 to reduce its water use and GHG emissions -- by the end of 2013, GE had reduced its global GHG emissions by 34 percent from 2004 and water use by 45 percent from 2006. To continue this progress, GE has announced 2020 commitments to invest a cumulative $25 billion in R&D and reduce water and greenhouse gas emissions by 20 percent from a 2011 baseline.

Honeywell
Honeywell, a global technology and manufacturing company, today announced its third public goal to reduce GHG emissions throughout its global business operations. Honeywell exceeded its first public goal to reduce GHGs by more than 30 percent from a 2004 baseline in 2011, and then achieved an additional 15 percent per dollar of revenue reduction from 2011 levels by 2014, three years earlier than originally planned. Because of this progress, the company set its latest five-year goal earlier than anticipated by 2019 Honeywell expects to achieve an additional 10 percent per dollar of revenue reduction from 2013 levels. Honeywell also has exceeded goals to increase energy efficiency in its businesses. The company&rsquos facilities have implemented more than 2,100 energy efficiency projects including building automation/controls, lighting, and mechanical upgrades since 2010.

SRA International
SRA International, a provider of IT solutions and professional services to government organizations, today announced a goal to reduce its GHG emissions by 35 percent by FY 2020 relative to a FY 2007 baseline. SRA&rsquos FY 2007 Scope 1 and 2 GHG goal baseline is 6,267.9 metric tons CO2-equivalent (MTCO2e). SRA has further committed to reduce paper use by 75 percent per person (from FY 2007 use) and to achieve a 90 percent recycling rate by FY 2020. SRA has committed to conducting its operations in an environmentally responsible manner and minimizing its environmental impacts. In 2007, SRA launched its Go Green initiative. Since then, the company has applied sustainability practices to many of its business operations and has identified, assessed and implemented initiatives to help it operate more efficiently and with a lighter environmental footprint.

Humana
Humana Inc., a health and well-being company, announced today that it will work to reduce its GHG emissions by 5 percent from 2015 through 2017, from a 2013 baseline. In 2012, Humana announced energy-saving goals, identifying and investing in a variety of energy-efficiency initiatives, primarily focused on owned real estate. By the end of 2012, the company achieved a 6 percent reduction in energy consumption. During 2013, the company realized an 8 percent reduction in energy consumption and a 3 percent reduction in GHG emissions (approximately 3,000 metric tons of carbon dioxide) from a 2009 baseline. Humana&rsquos facilities represent one of the company&rsquos biggest opportunities to increase efficiencies and reduce emissions. Humana will continue to invest in capital projects to support improvements in various owned and leased sites, including its data centers, adopting LED lighting standards, expanding waste-reduction programs, and continuing to explore renewable energy options. In addition, Humana acknowledges that its employees play an important role in achieving a healthy planet, and pledges to continue enhancing engagement efforts with associates, helping them become better stewards of the environment in the workplace and at home.

CSC
CSC, a next-generation information technology (IT) services and solutions provider, today confirmed its intention to meet an absolute global greenhouse gas reduction target of 18 percent by 2018 (baseline 2012). Through implementing best practices in data center power and cooling, employee education and real estate footprint consolidation, CSC has already achieved 8.7 percent reduction in greenhouse gas emissions in one year and eliminated 30,472 tons of Scope 1 (Direct), Scope 2 (Indirect) CO2e and Scope 3 (Travel) emissions across the business.

AECOM
AECOM, a global infrastructure design, build, finance and operating services firm, today announced it will identify the GHG issues relevant to its operations by October 2015 and set reduction targets for 2018. The firm will report progress toward those targets and the strategies employed will be reported in its annual enterprise sustainability report each year starting in 2016. Given the nature of AECOM&rsquos business, the firm will report on GHG issues related to the energy consumed (conditioning, water and waste) in the spaces it occupies &mdash in conjunction with its landlords &mdash as well as in areas related to travel, purchasing and printing.

Science Applications International Corporation (SAIC)
SAIC, a technology integrator for government and select commercial customers, announced today that it plans to publicly disclose its GHG emissions for calendar year 2014 to establish a baseline for emissions and to set a goal for a new GHG reduction target by March 2016. SAIC&rsquos GHG emissions for the first three months of operations (October &ndash December 2013) were 4,814 metric tons of carbon dioxide equivalents. SAIC recognizes that GHG emissions are an important metric in gauging an organization&rsquos overall environmental impact and corporate commitment to mitigate negative impacts.

HP
HP, one of the world&rsquos largest providers of information technology infrastructure, software, services, and solutions, is committed to reducing GHGs across its entire value chain. HP was the first global IT company to publish and verify its complete carbon footprint and take action to reduce its GHG emissions across all three parts of its value chain: operations, supply chain and products. HP set a goal to reduce total GHG emissions from its operations (Scope 1 and Scope 2) by 20 percent by 2020, compared to 2010 levels. This built on the company&rsquos previous goal of a 20 percent carbon reduction, which HP achieved in 2011&mdashtwo years early. In 2013, HP set the industry&rsquos first supply chain GHG emissions reduction goal: a 20 percent decrease in first-tier manufacturing and product transportation-related GHG emissions intensity by 2020, compared with 2010. In 2014, HP set a new goal to reduce the emissions intensity of its product portfolio by 40 percent by 2020 from a 2010 baseline, which will help HP and its customers worldwide reduce carbon impacts.

Northrop Grumman
Northrop Grumman Corporation, a global security company, is committed to environmental sustainability leadership. Northrop Grumman has announced its 2020 environmental sustainability goals: to reduce absolute GHG emissions 30 percent from 2010 levels to reduce water consumption by 20 percent from 2014 levels and to achieve a 70 percent solid waste diversion rate. As of year-end 2013, Northrop Grumman reduced its GHG emissions intensity by 26.5 percent relative to sales from 2008 levels and achieved its inaugural GHG reduction goal two years early. This performance resulted in the reduction of more than 260,000 metric tons of carbon dioxide equivalent.

United Technologies
United Technologies Corporation (UTC), a global aerospace and commercial building industries company, has reduced GHG emissions in its own operations by more than 30 percent since 2007. On the product side, the company&rsquos Carrier business calculates that installations of its high-efficiency heating, ventilating and air conditioning systems since 2000 have avoided the release of more than 164 million metrics tons of CO2 into the atmosphere. And UTC&rsquos Pratt & Whitney business&rsquos innovative PurePower jet engine cuts carbon emissions by over 3,600 metric tons per aircraft per year &ndash equal to planting more than 900,000 trees. UTC is committed to continuing its absolute GHG reduction and later this year will release new goals to be achieved by 2020.

CH2MHill
CH2M HILL, an employee-owned global consulting firm, set an absolute GHG reduction goal of 25 percent between 2012 and 2017 for global operations and is well over halfway toward meeting the 2017 target. The company&rsquos emissions have declined through reduced energy consumption and GHG emissions for vehicles and buildings improved efficiency of four LEED- and ENERGY STAR-certified headquarter buildings and office energy conservation programs. Looking forward, CH2M HILL plans to continue its energy management efforts, renewable energy investments, sourcing of high-quality carbon offsets, and additional actions for management of its Scope 3 carbon footprint. In February, CH2M HILL received the Excellence in Greenhouse Gas Management&mdashGoal Setting certificate from the U.S. Environmental Protection Agency, in collaboration with the Association of Climate Change Officers, the Center for Climate and Energy Solutions, and The Climate Registry at the fourth annual Climate Leadership Awards. CH2M HILL was one of the first in its sector to publish a sustainability report in 2005.

Furthermore, ADS plans to benchmark its internal energy and fuel consumption and put forth a reduction plan in 2015.

Battelle:
Battelle, a leading nonprofit research and development organization, announced today that it is committed to reporting GHG emissions beginning in 2016. Battelle is also setting a goal to reduce GHG emissions by 25 percent by the year 2025. Battelle has been participating in a continuous energy improvement program and will use the statistical model established in 2013 as the baseline. Battelle is committed to managing and operating corporate facilities in a sustainable manner. In harmony with reporting and reducing GHG emissions, Battelle will make every effort to apply strategies for sustainable buildings, pollution prevention, waste reduction, electronic stewardship, sustainable acquisition, renewable energy, and water efficiency. Battelle has already made significant investments in sustainability including a net-zero energy building, energy efficiency, and environmental protection.


Tracking the editor's carbon footprint

𠇍o you, Dr Godlee, consider yourself a climate criminal? If yes, what punishment would you consider for yourself?” The question comes from MedGadget (www.medgadget.com), a web only publication, in response to an editorial co-written by the BMJ's editor, Fiona Godlee, which called for doctors “to lead by example on climate change by reducing the carbon footprint of medical conferences” (BMJ 2007334:324-5 doi: 10.1136/bmj.39125.468171.80). Tracking Dr Godlee's carbon footprint from her flights, the editors of the website wrote: “What we can say is that Dr Godlee is a ‘has been there, done that' kind of person. And we mean around the world, most likely in business class”𠅊nd accused her of hypocrisy.

In response, Hugh Montgomery of University College London, a member of the BMJ's Carbon Council (http://resources.bmj.com/bmj/about-bmj/carbon-council-1), drew attention to the fact that most of the trips made by Dr Godlee were within the UK, and that personal attacks such as these were 𠇊n unhelpful diversion.” He added: “Six were foreign trips made well before the Climate Change issue had been openly publicly raised or had reached the consciousness of most, and when debate even over its existence was continuing in many circles.”

To this, another respondent wrote that Dr Godlee had stressed the importance of global warming from 1996. Using data from Dr Godlee's carbon blog (www.bmj.com/cgi/content/full/332/7554/DC1), he wrote: 𠇌ounting her personal carbon footprint in the same post, she calculates it as 10.5 tonnes per year. 𠆊nd if you add in my travel by train and plane for work (22 tonnes), my tonnage is 32.5.' And this is after more than a decade of ‘grave' concern. As one of her resolutions considering all this she decides: ‘I'm putting climate change on the agenda for the next International Committee of Medical Journal Editors meeting because we've got to get the Americans on board somehow.' The tonnage for an average American is 7.2.”

Subsequently, MedGadget also set up an interactive map to monitor Dr Godlee's footprint (www.medgadget.com/archives/2007/02/fionagate_an_il.html): 𠇏rom now on, we will be monitoring Dr Godlee's travels, as well as BMJ-sponsored events, and will bring that to your attention. We can assure you that we will not allow Dr Godlee to display the hypocrisy of her behavior without a response. Her editorials are nothing but ego trips of feel-good ideas of failed deeds.”

Dr Godlee responded on MedGadget: “I'm afraid you give me too much credit. I first wrote about climate change in the BMJ not in 1996 but in 1991 (BMJ 1991303:1254-6). And my business travel is rather more extensive than you have so far managed to document indeed were it not so I might be charged with failing to do my job. But I'm grateful to you for taking the trouble to track my carbon footprint and for keeping me on my toes about this.

“To your charge of hypocrisy I am tempted to hold my hand up and say that this is a fair cop. But on the basis of what I have written I don't think the charge stands. In our recent editorial, Ian Roberts and I said:

1 Climate change is important

2 Air travel contributes to it

3 Much air travel is unnecessary

4 We should try to reduce it and some are already doing so.

You don't argue with any of these substantive points.”

The editors of MedGadget were “pleased with the dialogue,” but “when a globe-trotting editor of a pulp publication tells us we should cut down on our activities, it rubs us the wrong way.” More importantly, they added: “Since deforestation's contribution to global warming outweighs that of air travel, we'd love to hear some announcements about BMJ phasing out their costly, wasteful paper products, and joining us in the realm of web-only publications” (www.medgadget.com/archives/2007/03/in_response_to.html).

Their final advice is straightforward: “Instead of scolding and urging others to sacrifice, she should use her position as head of an esteemed scientific journal to promote research on the wastefulness of conferences and paper journals, and steer the British Medical Journal clear of those practices.”
