LC 669: Requiring public utilities to report a plan for 100% renewables

This bill requires public utilities in Montana to create and submit detailed plans by June 1, 2026, outlining how they intend to transition to 100% renewable energy sources for their retail sales. The plans must include specific options, timelines, and challenges related to achieving this goal, with hydroelectric resources potentially included as part of the renewable mix. Additionally, each utility must address how its proposed transition will reduce greenhouse gas emissions in compliance with state constitutional requirements. The Energy and Telecommunications Interim Committee will review these plans, gather public feedback, and provide recommendations to the next legislature for further action.

LC 1392: Require rules to limit GHG emissions

This bill directs the Montana Department of Environmental Quality to create rules that limit greenhouse gas emissions to protect public health, safety, welfare, and the environment. It expands the department's existing authority to regulate air pollutants by explicitly requiring it to develop emission limits while exempting certain agricultural and forestry activities from new permitting requirements. The legislation also allows the department to require access to emissions-related records and establish fees for permits and applications. These changes apply to the state environmental agency and any entities subject to its air quality regulations, with specific carve-outs for short-term agricultural and forestry operations.

LC 3841: Generally revise Montana environmental policy act to implement court decision

This bill amends Montana's Environmental Policy Act to comply with a state Supreme Court ruling, requiring state agencies to evaluate greenhouse gas emissions in environmental reviews. It removes previous language that prohibited considering greenhouse gases and mandates that agencies analyze alternatives to proposed projects, including a meaningful no-action alternative that assesses environmental, social, and economic impacts if a project is not completed. The changes also require agencies to examine how regulations affect private property rights and ensure that environmental assessments include customer fiscal impact analyses where applicable. These provisions apply to all state agencies except the legislature and affect the process for reviewing state-sponsored projects that could impact Montana's environment.

LC 4171: Generally revise the Montana environmental policy act

This bill requires state agencies in Montana to conduct greenhouse gas assessments for proposed fossil fuel projects as part of their environmental reviews under the Montana Environmental Policy Act. The legislation clarifies that while agencies cannot deny permits based on greenhouse gas emissions, they must still analyze these emissions for fossil fuel activities to inform the public about potential impacts. The bill amends existing environmental review statutes to mandate this analysis for fossil fuel projects while maintaining that greenhouse gases will not be regulated through this process. State agencies conducting environmental reviews will follow updated guidelines that specify when greenhouse gas assessments are required versus optional.

LC 2340: Require legislative approval of greenhouse gas rules

This bill requires that any state agency rules or regulations concerning greenhouse gas emissions or the social cost of carbon must be approved by the Montana Legislature before they can take effect. It directly affects state departments, commissions, and boards that have the authority to create rules on these environmental topics. The key mechanism is a delay provision that prevents such rules from becoming effective until the legislature reviews and approves them during the next legislative session. Additionally, the bill includes instructions on how these new requirements should be added to the state's existing legal code.

LC 2339: Exempt GHG emissions analysis for appliances, vehicles, engines

This bill exempts state and local building departments from conducting greenhouse gas emissions analyses for certain appliances, vehicles, and engines under Montana's environmental review process. The exemption applies to products regulated by federal laws that preempt state authority, such as those governed by the Clean Air Act and Energy Policy and Conservation Act, as well as emissions originating outside Montana's borders. By removing these specific sources from environmental review requirements, the bill clarifies that state agencies do not need to assess greenhouse gas impacts for items where federal law already establishes national standards. The legislation also provides instructions for codifying these exemptions into existing state environmental statutes.

LC 2205: Clarify state's position on global warming and greenhouse gases

This bill (LC 2205) is a declarative statement by the Montana Legislature asserting the state's position on climate science, directly challenging the Montana Supreme Court's ruling in *Held v. Montana*. It disputes specific findings from the court case, including claims about human-caused warming, greenhouse gas accumulation, and climate impacts, arguing scientific consensus is irrelevant to climate science. The bill does not establish new environmental regulations, reporting requirements, or policy changes - it solely aims to formally reject the court's scientific conclusions. It addresses the legal context of the *Held* case but contains no concrete policy mechanisms or affected parties beyond the state's official stance.

LC 1391: 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.

SB 221: Generally revise the Montana environmental policy act

SB 221 revises the Montana Environmental Policy Act (MEPA) by establishing new requirements for greenhouse gas (GHG) assessments during state agency environmental reviews. Under this bill, state agencies are mandated to conduct GHG assessments for proposed actions classified as "fossil fuel activities." For other proposed actions, agencies may conduct a GHG assessment if deemed necessary for MEPA compliance. The bill clarifies that these assessments are for informational purposes, and state agencies cannot regulate greenhouse gas emissions or deny permits based solely on these GHG assessments under MEPA. This affects Montana state agencies conducting environmental reviews and entities proposing fossil fuel-related projects.

HB 660: Require rules to limit GHG emissions

HB 660, titled "Require rules to limit GHG emissions," would have mandated the Montana Department of Environmental Quality (DEQ) to develop specific rules for limiting greenhouse gas emissions. This bill sought to amend existing state law (Section 75-2-112, MCA) by requiring the DEQ to create regulations to protect public health, safety, welfare, and the environment from these emissions. The legislation directly affects the DEQ by expanding its regulatory responsibilities to include greenhouse gases.
