WASHINGTON, D.C. — U.S. Sen. Mike Crapo of Idaho has joined Sen. John Barrasso of Wyoming and more than 20 other Republican senators in introducing legislation that would require Senate approval before the United States can enter or reenter any international climate agreement, according to a news release issued Tuesday.
The proposed legislation, titled the No Climate Treaties Act of 2026, would classify international climate agreements as treaties under the U.S. Constitution. As a result, any such agreement would need approval from two-thirds of the Senate before taking effect.
The bill was introduced following the United States’ official withdrawal from the Paris Climate Agreement. Under the legislation, agreements that mandate legally binding reductions in domestic greenhouse gas emissions — including the Paris Agreement — would be subject to the Senate’s advice and consent process outlined in Article II of the Constitution.
In addition to the approval requirement, the bill would prohibit the use of federal funds to implement or comply with any international climate agreement that has not received Senate approval.
Crapo said in the release that the legislation is intended to prevent future administrations from entering international climate agreements without congressional oversight.
The bill is co-sponsored by multiple Republican senators, including Idaho Sen. Jim Risch, along with lawmakers from Kansas, Tennessee, Louisiana, Utah, Florida, Texas, Arkansas, West Virginia, Wyoming, Alabama, Montana, Mississippi, Missouri, and Kentucky.
The legislation has been introduced in the U.S. Senate and referred to committee for consideration.
