United States enacts the Inflation Reduction Act with historic clean-energy investment

On 16 August 2022 President Biden signed the Inflation Reduction Act, which directs roughly $369 billion toward clean energy and climate measures - tax credits for solar, wind, storage, EVs and domestic clean-tech manufacturing - the largest U.S. climate investment to date, projected to cut emissions about 40% by 2030.

Who was responsible

Contribution type and responsibility level for each recorded actor — not sole-author shorthand.

  • Joe Biden

    Person

    Shared responsibility

    responsibility level 0.7 · verified

    Biden approved and signed Public Law 117-169 on 16 August 2022. The contribution is limited to the presidential enactment role and does not assign him sole authorship of the legislation.

  • United States Congress

    Organization

    Shared responsibility

    responsibility level 0.7 · verified

    Congress enacted Public Law 117-169, including the clean-electricity tax-credit and investment provisions. The contribution records the legislature's institutional role in passage.

  • Joe Manchin

    Person

    Shared responsibility

    verified

    Manchin and Schumer jointly announced that they had finalized the Inflation Reduction Act agreement after months of negotiations. This supports Manchin's direct legislative contribution to the already-reviewed IRA fact; it does not claim that he personally implemented later CMS price negotiations.
