The Mountain region (AZ, CO, ID, MT, NV, NM, WY) sees economic gains from a carbon fee and dividend policy. By 2025, the region is expected to have a $10 billion increase in gross regional product, 220,000 new jobs, and higher real income per capita. While mining and fossil fuel industries contract, other industries like real estate, retail, and healthcare see growth. The policy leads to cleaner energy from wind, natural gas with carbon capture, and geothermal, replacing lost coal power. On balance, the Mountain region experiences overall economic expansion and environmental benefits from the carbon fee and dividend policy.
