MT HB229

Removes the prohibition on evaluating greenhouse gas emissions and corresponding climate impacts in environmental reviews conducted under the Montana Environmental Policy Act, implementing the Montana Supreme Court's decision in Held v. State of Montana

Eliminates the provision that prevented legal challenges based on greenhouse gas emissions from vacating, voiding, or delaying permits, licenses, or other authorizations

Amends MCA sections 75-1-102, 75-1-201, and 75-1-208 to strike language that previously barred climate impact analysis unless required by a federal agency or Congress amended the Clean Air Act to regulate carbon dioxide

Retains existing procedural requirements for environmental reviews, including time limits (60 days for public scoping, 90 days for standard reviews, 180 days for detailed statements) and judicial challenge procedures
