Requiring certain entities doing business in Montana to disclose their greenhouse gas emissions

This bill (LC 1391) proposed requiring certain businesses operating in Montana to publicly report their greenhouse gas emissions. It would have directly affected large commercial entities meeting specific size or emission thresholds within the state. The bill outlined a reporting mechanism for entities to submit annual emissions data to a state agency. However, the bill was drafted in November 2024 and ultimately died in the legislative process by May 2025, meaning it never became law and no policy changes were implemented.
