# California study: gas stoves leak methane even when off 2026-08-12T23:13:21+00:00 | World & Diplomacy | Indian Opinion Desk Corroboration: 1 independent outlet A study of 53 California homes found that gas stoves release methane even when switched off. More than three-quarters of the measured methane came from the steady-state-off condition, not from cooking. The researchers at Stanford University and PSE Healthy Energy estimate that US gas stoves emit about 28.1 gigagrams of methane annually, with a climate impact over 20 years comparable to the carbon dioxide from 500,000 passenger cars. The leaks come from post-meter connections and appliance components. Methane is a powerful greenhouse gas, and the same molecule is also sought by astronomers as a possible biosignature on distant planets. ## Coverage - timesofindia.indiatimes.com Tags: California, climate change, gas stoves, indoor-air-quality, methane, research Canonical: https://indianopinion.org/california-study-gas-stoves-leak-methane-even-when-off/ License: Summary and commentary (c) Indian Opinion, reusable with attribution.
