L'augmentation des émissions mondiales de gaz à effet de serre marque un ralentissement

Un rapport publié par l'Agence néerlandaise pour l'évaluation de l'environnement montre que la hausse des émissions de gaz à effet de serre en 2016 a été la plus lente depuis le début des années 1990.

A report published by PBL Netherlands Environmental Assessment Agency on September 28, 2017, calculates the global increases of greenhouse gases (GHG) emissions in 2014, 2015 and 2016. The results show that emissions reached 49.3 GT of CO2.

Most of the emissions (about 72%) consist of CO2, but methane (CH4), nitrous oxide (N2O) and fluorinated gases (F-gases) also make up substantial shares (19%, 6% and 3%, respectively). HFC-134a represents a large sub-category of F-gases, with about 19% of emissions.

Most countries showed a decrease in CO2 emissions in 2016; most notably the USA (-2.0%), the Russian Federation (-2.1%), Brazil (-6.1%), China (-0.3%), and the UK (-6.4%). In contrast, the largest absolute increases were seen in India (+4.7%) and Indonesia (+6.4%).
