Methane emissions are rising faster than ever

The world has not hit the brakes on methane emissions, a powerful driver of climate change. More than 150 nations have pledged to slash by 30% this decade under a global methane pledge, but new research shows global methane emissions over the past five years have risen faster than ever. Atmospheric concentrations of methane are now more than 2.6 times higher than in pre-industrial times – the highest they’ve been in at least 800,000 years. Methane emission rates continue to rise along the most extreme trajectory used in emission scenarios by the world’s leading climate scientists.

Despite growing policy focus on methane, however, total annual methane emissions have increased by 61 million tons or 20% over the past two decades, according to the new estimates. Increases are being driven primarily by growth of emissions from coal mining, oil and gas production and use, cattle and sheep ranching, and decomposing food and organic waste in landfills.

In 2020, the most recent year for which complete data are available, nearly 400 million tons or 65% of global methane emissions came directly from human activities, with agriculture and waste contributing about two tons of methane for every ton from the fossil fuel industry. According to the researchers, human-caused emissions continued to increase through at least 2023.
