The Environmental Protection Agency has terminated grant agreements worth $20 billion issued by the Biden administration under a so-called green bank to finance clean energy and climate-friendly projects.

The green bank was quickly targeted by EPA administrator Lee Zeldin, who was confirmed to the role in late January.

Clean-energy nonprofit Climate United says the EPA grant freeze is causing catastrophic harm to project employees, contractors and service providers.

In a related action, the Coalition for Green Capital, a separate group that received $5 billion from the Biden-era program, sued Citibank Monday, alleging breach of contract over the refusal to disburse the grant funds awarded by the EPA.
