Carbon neutrality in the United States

Carbon neutrality in the United States refers to reducing U.S. greenhouse gas emissions to the point where carbon emissions are neutral compared to the absorption of carbon dioxide, and often called "net zero". Like the European Union, and countries worldwide, the United States has implemented carbon neutrality measures and law reform at both federal and state levels:
 * the Presidency has set a goal of reducing carbon emissions by 50% to 52% compared to 2005 levels by 2030, a carbon free power sector by 2035, and for the entire economy to be net zero by 2050.
 * by April 2023, 22 states, plus Washington DC and Puerto Rico had set legislative or executive targets for clean power production.
 * all cars or light vehicles will have zero emissions (i.e. no internal combustion engine with gas or diesel) by 2035 in light duty vehicles, and no longer be bought by federal government by 2027.
 * the California Air Resources Board voted in 2022 to draft new rules banning gas furnaces and water heaters, and requiring zero emission appliances in 2030. By 2022, four states have gas bans in new buildings.
