Web1 In addition to CO 2, other greenhouse gases, such as methane and nitrogen dioxide, are also responsible for the climate problem. These are stronger than CO 2 . Where CO 2 is mainly released during the burning of fossil fuels, methane and nitrogen dioxide are mainly released during decomposition processes (fermentation) of waste. Web20 aug. 2024 · Les émissions de méthane d'origine humaine pourraient être réduites de 45 % au cours de la décennie. Cela permettrait d'éviter un réchauffement climatique de près de 0,3 °C d'ici à 2045, contribuant ainsi à limiter la hausse de la température mondiale à 1,5˚C et mettant la planète sur la voie des objectifs de l'Accord de Paris.
