The Threats of Gas Appliances Every day, domestic gas-powered building appliances emit 65 tons of toxic and highly reactive gases called nitrogen oxides (NOx) per day. The Rule and Other Potential Developments By adopting this rule, BAAQMD is exercising its legal authority under both federal and state law to regulate nitrogen oxides.

This year, the Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) proposed new emissions and fuel economy standards (respectively) for model year 2027-2032 passenger cars and light trucks (sedans, utility vehicles, pickups, etc.). We cannot afford such harm in the middle of a climate crisis.
