Les \u00e9missions de m\u00e9thane, un gaz \u00e0 effet de serre, restent \u00ab\u00a0\u00e0 des niveaux tr\u00e8s \u00e9lev\u00e9s\u00a0\u00bb dans les \u00e9nergies fossiles, alerte lundi l’AIE, estimant que la r\u00e9cup\u00e9ration de ces rejets pourrait fournir du gaz suppl\u00e9mentaire dans le contexte de la crise \u00e9nerg\u00e9tique.
En 2025, la production record du secteur des \u00e9nergies fossiles (p\u00e9trole, charbon, gaz) a \u00e9t\u00e9 responsable de 35% des \u00e9missions de m\u00e9thane provenant de l’activit\u00e9 humaine, soit 124 millions de tonnes (Mt), estime l’Agence internationale de l’\u00e9nergie dans son rapport annuel. En l\u00e9g\u00e8re hausse par rapport \u00e0 2024 (121 Mt), ces \u00e9missions \u00ab\u00a0restent \u00e0 des niveaux tr\u00e8s \u00e9lev\u00e9s\u00a0\u00bb, proches des records de 2019, domin\u00e9es par le secteur p\u00e9trolier (45 Mt), devant le charbon (43 Mt) et le gaz (36 Mt). Il n’y a \u00ab\u00a0aucun signe que les \u00e9missions mondiales de m\u00e9thane li\u00e9es \u00e0 l’\u00e9nergie aient diminu\u00e9 en 2025 \u00ab\u00a0, souligne l’AIE.
Inodore et invisible, le m\u00e9thane, principal composant du gaz naturel, s’\u00e9chappe notamment des gazoducs, des vaches et des d\u00e9charges.
Environ 580 millions de tonnes de m\u00e9thane sont rejet\u00e9es chaque ann\u00e9e dans le monde, dont 60% attribuables \u00e0 l’activit\u00e9 humaine avec l’agriculture en t\u00eate suivie de l’\u00e9nergie.
Dot\u00e9 d’un pouvoir bien plus r\u00e9chauffant que le CO2, le m\u00e9thane est responsable d’environ 30% de la hausse de la temp\u00e9rature moyenne mondiale depuis la r\u00e9volution industrielle. Mais sa dur\u00e9e de vie \u00e9tant plus courte, le r\u00e9duire offre \u00ab\u00a0des \u00ab\u00a0b\u00e9n\u00e9fices climatiques significatifs \u00e0 court terme\u00a0\u00bb, souligne l’AIE.<\/p>\n","protected":false},"excerpt":{"rendered":"
