Methane, a greenhouse gas with a warming potential more than 80 times higher than CO2 over a 20-year time frame, is responsible for half a degree Celsius of warming to date. Methane’s concentration in the atmosphere has been increasing rapidly over the last 15 years. Human activity in three sectors account for more than half of global methane emissions, with agriculture accounting for 40% of emissions, fossil fuels for 35%, and waste for 20%. However, available measures could reduce methane emissions across these three sectors by as much as 45% by 2030. Reducing methane emissions from anthropogenic sources is one of the most cost-effective strategies to rapidly reduce the rate of global warming and meet the goals of the Paris Agreement, while contributing to Sustainable Development Goals.
Through collaboration and shared knowledge, the identification and implementation of methane pollution solutions becomes faster, scalable, and accessible. The Climate and Clean Air Coalition, Clean Air Task Force, GIZ, the International Finance Corporation, and World Resources Institute have the expertise and capacities to support nations in their methane pathways. By adopting more of the technological or regulatory approaches described in these factsheets, countries can continue with their efforts to turn their ambitions into action by cutting global methane.
