Methane: The Climate Crisis Within the Climate Crisis
While carbon dioxide receives most of the attention in climate discussions, methane is a far more potent greenhouse gas over the short term — approximately 80 times more warming than CO2 over a 20-year period. It accounts for roughly 30% of the global warming experienced since the industrial revolution. And unlike CO2, methane breaks down in about a decade — meaning that cutting methane now would produce rapid, measurable reductions in warming within years.
Where Methane Comes From
The three largest sources of anthropogenic methane are fossil fuels — particularly gas and oil leaks and flaring — livestock agriculture, and landfill waste decomposition. Satellite data published in 2026 has revealed that methane leaks from oil and gas infrastructure are systematically underreported, with actual emissions running 40 to 70% higher than official national inventories in some regions including parts of the US, Russia, and the Middle East.
The Global Methane Pledge: Progress and Gaps
Over 150 countries have signed the Global Methane Pledge, committing to a 30% reduction in methane emissions from 2020 levels by 2030. But current policies are tracking to deliver only about half that ambition. UN Secretary-General Guterres made emergency methane cuts the centrepiece of his address at London Climate Action Week in June 2026, calling it the fastest and most affordable lever available to slow warming in the critical near term.
