The Department of Energy (DOE) issued a rule Friday mandating standards for residential gas furnaces to reduce "greenhouse gas emissions," according to a press release.

The DOE said it has proposed or finalized rules for new efficiency standards for 24 appliances in its attempt to reduce greenhouse gas emissions, according to the press release. The new rule, opposed by the American Gas Association (AGA), which said it might prohibit 40-60% of gas furnaces in homes, will take effect in 2028 and require residential furnaces to have an annual fuel efficiency of 95%.

"At the direction of Congress, DOE is continuing to review and finalize energy standards for household appliances, such as residential furnaces, to lower costs for working families by reducing energy use and slashing harmful pollutants in homes across the nation," Secretary of Energy Jennifer Granholm said, according to the press release.
