Study: New law in the US will reduce carbon emissions by 40%

Incentives for clean energy in the new spending package signed this week by US President Joe Biden will reduce greenhouse gas emissions by about 1.1 billion tonnes (1 billion metric tons) by 2030, according to an analysis by the Energy Department.

The first federal estimates, shared with the Associated Press ahead of publication Thursday, show that between newly signed legislation and last year’s infrastructure spending bill, the United States will produce about 1.26 billion tons of carbon by the end of the decade. Less carbon than it would be without both laws. Those savings equal the annual greenhouse gas emissions of all households in the United States.

A Department of Energy analysis concluded that with the new law, the country’s emissions of these gases should be about 40% below 230 levels by 2005, yet not at the intended level declared by the United States. Reduce pollution with carbon between 50% and 52% by the end of the decade. But the 40% reduction is similar to a previous calculation by independent research firm Rhodium Group, which indicated the reduction would be between 31% and 44%, and scientists at Climate Action Tracker, who forecast them between 26% and 42%. . ,

The analysis suggests that most of the projected emissions reductions in the roughly $375 billion spending package will come from the promotion of “clean energy,” mostly solar and wind power, and electric vehicles. It added that more than half of the projected cuts would be from the way electricity is generated in the country. About 10% of the emissions savings will come from agriculture and land conservation.

The federal analysis noted that the new land provisions in the law that provide for oil and gas leases on federal land “may lead to some increase” in carbon emissions, but other provisions to encourage clean energy are available for each new tonne. 35 tons of gas will reduce greenhouse gas. Pollution from oil and gas exploration.

Independent experts such as Climate Action Tracker’s Bill Hare say the new law is a significant step forward for the United States, but still inadequate because the country, the biggest emitter of carbon, has done little in decades and is lagging behind Europe. .
