Short summary
We measured measured CH₄, CO₂, CO, and NOx emissions from household gas stoves in Chile and Colombia. We found that emissions are much higher than official estimates, mainly due to small leaks and ignition. These hidden emissions contribute to climate change and air pollution. Our work shows the need for better measurement, reporting, and appliance standards to reduce environmental impacts from everyday cooking.
