This bill, known as the "Ending Green Giveaways Act," aims to eliminate a specific provision within the Clean Air Act. Its primary purpose is to repeal section 138 of the Clean Air Act, which is dedicated to establishing and funding environmental and climate justice block grants. Furthermore, the legislation mandates the rescission of any unobligated balances of funds that were previously made available under the now-repealed section 138. This action would effectively terminate the program and withdraw any remaining financial resources allocated for these particular grants, thereby ending federal support for such initiatives.
