To mark World Ocean Day, U.S. Congressman Robert Garcia (CA-42), alongside Senator Alex Padilla (D-California), have introduced new legislation to help curb greenhouse gas emissions from shipping by limiting, and eventually eliminating, the carbon intensity of marine fuel used by ships calling at U.S. ports.

The Clean Shipping Act of 2023 would amend the Clean Air Act to set a path to eliminate greenhouse gas emissions from ships doing business with the U.S. by 2040, while giving the Environmental Protection Agency the authority to regulate carbon intensity standards for maritime fuel.
