MEIC is known throughout Montana and the West as a strong advocate for a clean and healthful environment that backs advocacy with hard science and thorough research. We have been called “perhaps the most influential and active environmental organization in the state” and for good reason. For almost 50 years, MEIC has fought for policies that will affect the Montana environment for generations to come. Below is a list of MEIC’s biggest accomplishments, but does not include the full breadth of our work and success.

At the Legislature

MEIC is the lead voice for the environment at the Montana Legislature. We have played a role in lobbying to establish, protect, and strengthen almost every environmental law on the books, including but not limited to the Montana Environmental Policy Act, the Subdivision and Platting Act, the Major Facility Siting Act, the Strip and Underground Mine Reclamation Act, the Voluntary Conservation Easements Act, the Coal Severance Tax Trust Fund, the Metal Mine Reclamation Act, the Comprehensive Environmental Clean-up and Responsibility Act, the Mega Landfill Siting Act, the Water Use Act, and the Renewable Energy Standard. MEIC has also played a lead role in defeating hundreds of anti-environmental bills that are not listed his.
