The main purpose of this legislation, titled the "No Climate Treaties Act of 2026," is to ensure that any international climate agreement the United States wishes to enter into or rejoin requires approval from the Senate. This includes agreements that impose legally binding limits on domestic greenhouse gas emissions, such as the Paris Agreement. Key provisions of the legislation include a requirement that any international climate agreement be treated as a treaty. This means that it must be submitted to the Senate for its advice and consent, following the constitutional process.
