MO HB2543

Requires the Missouri Department of Natural Resources, the commission, and all other state agencies to immediately suspend all activity related to the EPA's Clean Power Plan, which regulates carbon dioxide emissions from power plants under section 111(d) of the Clean Air Act

Prohibits state agencies from resuming any Clean Power Plan-related activities until litigation over the plan has been fully adjudicated and the General Assembly approves resumption through a concurrent resolution passed by majority vote in both chambers

Declared an emergency act, meaning it takes effect immediately upon passage and approval rather than following the standard effective date

Stated justification is preserving the state's ability to regulate electricity within its borders to ensure reliable and affordable electricity supply for Missouri citizens
