"The Biden administration is proposing a more stringent efficiency standard for new home heating appliances, a move it says will both lessen climate change and save consumers money.
The proposed standard pertains to certain types of furnaces that run on natural gas and requires them to operate at 95 percent efficiency.
In a statement, the Energy Department said that the proposed changes — which, if adopted, will go into effect in 2029 — will save consumers $1.9 billion annually.
Over a 30-year period, they will also cut planet-warming emissions of carbon dioxide by 373 million metric tons and methane by 5.1 million tons, the equivalent of the emissions from 61 million homes, according to the department."
