As a result of the Inflation Reduction Act (IRA), the US economy is on track to emit between 35% and 43% less carbon dioxide by 2030 than it did in 2005, according to a US government assessment released on Tuesday.

President Joe Biden’s IRA, which went into effect in August 2022, provides billions of dollars in tax credits to assist customers in purchasing electric vehicles and businesses in producing renewable energy.

The Environmental Protection Agency (EPA) report analyzed the impacts an estimated $391 billion of support under the IRA for climate and clean energy programs and incentives through 2031.

U.S. annual carbon dioxide emissions should decline to a median of 3,300 metric tons in 2035, below the 4,100 MT projected without the IRA – equivalent to shutting 214 coal-fired power plants – and down from 6,130 MT in 2005, the report said.

The report showed that the EPA “has supercharged climate action in the United States,” said John Podesta, a senior White House adviser on clean energy.

It projected CO2 emissions from electricity production in 2030 declining by 49% to 83% from 2005 levels, largely driven by greater use of solar and wind output.

By 2035, electricity CO2 emissions on average will be half of what they would be in the ‘No IRA’ scenario, the models showed.

The modeling does not include the impact of a contested plan announced by the EPA in July to slash U.S. power plant emissions through large-scale use of carbon capture and green hydrogen.
