Environmental Protection Agency Administrator Lee Zeldin’s efforts to cancel $20 billion in climate grants meant to fund clean energy projects in low-income communities have led to litigation and controversy.

The grants were issued through the Biden administration’s Greenhouse Gas Reduction Fund, which was established as part of the 2022 Inflation Reduction Act passed by Democrats and signed by former President Joe Biden and included hundreds of billions of dollars in subsidies for clean energy. The fund was given a total of $27 billion, with $7 billion for a solar program called Solar for All and $20 billion to be distributed to eight nonprofit organizations through two major initiatives: the National Clean Investment Fund and the Clean Communities Investment Accelerator.
