This joint resolution seeks to reject an Environmental Protection Agency rule that sets greenhouse gas emissions standards for heavy-duty vehicles under Phase 3 regulations. The rule, published in April 2024, would establish new pollution limits for trucks and other large vehicles. If passed, this resolution would overturn the EPA regulation and prevent it from taking effect. The measure is sponsored by a bipartisan group of House members primarily from Republican districts. No specific funding is mentioned, as this resolution is focused on blocking a regulatory action rather than appropriating money or establishing new programs.
