Shirin Carbon na Duniya

The Global Carbon Project ( GCP ) kungiya ce da ke neman kididdige hayaki mai gurbata yanayi a duniya da musabbabinsa.  An kafa shi a cikin 2001, ayyukansa sun haɗa da kasafin kuɗi na duniya don manyan iskar gas guda uku - carbon dioxide ( CO  ), methane (  ), da kuma nitrous oxide (  ) -da kuma ƙarin ƙoƙarce-ƙoƙarce a cikin birane, yanki, tarawa, da gurɓataccen iska.
