The new president has sought to put a stop to predecessor Joe Biden’s “Green New Deal” and funding under the 2022 Inflation Reduction Act.

The 2022 law, which had bipartisan support, contains a variety of subsidies and tax credits for green and blue fuels that can be used in shipping and other industries looking for low-carbon alternatives.
