Solutions Series: Cutting Methane Emissions

Methane is a potent greenhouse gas with over 80 times the warming power of CO2 over 20 years, though it breaks down in about 12 years. Approximately 60% of methane emissions result from human activity, primarily agriculture (40%), the energy sector (35%), and waste management (20%). The five largest global emitters are China, the U.S., Russia, India, and Brazil. In the U.S., the energy sector's contribution is estimated by the IEA at 54%, significantly higher than the EPA's 38% due to underreported 'ultra-emitting events'. Reduction strategies include repairing leaks in oil and gas production, capturing biogas from waste and agriculture, and using alternative livestock feed. Measurement is shifting from 'bottom-up' inventories to 'top-down' remote sensing via satellites and aircraft to better identify point sources. The Global Methane Pledge, launched at COP26, aims for a 30% reduction in global methane emissions from 2020 levels by 2030, though several top emitters have not yet joined.

• Methane is a highly potent but short-lived greenhouse gas; it traps over 80 times more heat than CO2 over a 20-year period but decomposes in the atmosphere after approximately 12 years.
• Human activities account for roughly 60% of global methane emissions, with the primary contributors being agriculture (40%), the energy sector (35%), and waste management (20%).
• There is a significant discrepancy between reported and actual methane emissions in the energy sector; the IEA estimates global energy sector emissions are about 70% higher than national inventories, and U.S. energy sector emissions are 54% compared to the EPA's 38% estimate.
• The Global Methane Pledge involves 125 nations committing to reduce global methane emissions by at least 30% from 2020 levels by 2030, although half of the top emitting countries, including China, Russia, and India, are not participants.
