Over 40 million natural gas stoves in the US release methane (CH4) via incomplete combustion, leaks (when off), and at ignition. Up to 1.3% is unburned methane (U.S. annual total 28.1 Gg ), equivalent to 500,000 cars (over 3/4 when off). Health-damaging pollutants such as nitrogen oxides (NOx) are also emitted and can trigger respiratory diseases.
