Methane Pollution Has Cheap, Effective Solutions That Aren’t Being Used

The article highlights methane as a potent greenhouse gas that, despite being odorless and colorless, significantly contributes to global warming—trapping up to 84 times more heat than carbon dioxide over a short timeframe. Methane emissions, largely driven by human activities such as energy production and cattle farming, account for nearly a third of the global temperature increase since the Industrial Revolution. Recognizing its impact, over 100 countries pledged in 2021 to reduce methane emissions by at least 30% below 2020 levels by 2030. However, major emitters like Russia and China have not committed, and global methane emissions from energy production continue to rise, partly due to inadequate measurement and reporting. The article also underscores the challenges in tracking methane emissions accurately, as measurement-based data is scarce and emissions often go underreported. Methane leaks occur throughout the natural gas lifecycle—from drilling and transportation to consumption—and from coal mining, which releases even more methane than natural gas production. Despite the availability of low
