The Inflation Reduction Act (IRA) is the single largest climate investment that the US government has ever made. Signed into law in August 2022, the legislation includes $369 billion in funding for climate solutions and environmental justice initiatives, with the ultimate goal of reducing carbon emissions by 40% by 2030.
