SB 1383 repeals Arizona's existing greenhouse gas program framework, specifically removing Title 49, Chapter 1, Article 6 of the Arizona Revised Statutes. This bill directly affects any current or future state programs operating under that repealed legal authority. The bill contains no new provisions or mechanisms - it solely eliminates the existing statutory structure for greenhouse gas programs. No new requirements or prohibitions are created; the action is purely a repeal of prior law.
HB 2356 repeals Title 49, Chapter 1, Article 6 of the Arizona Revised Statutes, which previously established a statutory framework for greenhouse gas programs. This repeal removes the specific legal provisions governing such programs in Arizona's law. The bill directly affects the regulatory structure for greenhouse gas initiatives by eliminating the existing statutory basis. As a repeal bill, it does not create new programs or directly impact specific entities, but rather removes the legal foundation for prior greenhouse gas program regulations. The bill is currently in early legislative stages (House First and Second Readings as of January 2026).
HB 2912 requires Arizona electric utilities to submit detailed integrated resource plans to the Corporation Commission every three years. These plans must project 15-year energy demand (with low/medium/high scenarios), detail existing and planned generation assets, analyze costs and reliability of potential new plants, and use a ratepayer impact test to select the lowest-cost, most reliable option - without prioritizing emissions goals. The Commission must also obtain an independent third-party review of each plan to verify data and evaluate alternatives. The bill includes optional analysis of carbon emissions across all plant lifecycle stages (scopes 1-3), but the core requirement focuses on cost, reliability, and transparency for ratepayer decisions.
This is not a legislative bill but a memorial (SCM 1004) from Arizona's state legislature, not a federal bill. It requests Congress to clarify the EPA's authority to regulate greenhouse gases like CO2 and methane, arguing the EPA lacks explicit statutory power under the Clean Air Act and that current regulations violate the "major questions doctrine" established by the Supreme Court in *West Virginia v. EPA* (2022). The memorial specifically asks Congress to end EPA "regulation overreach" by defining the agency's powers regarding greenhouse gas emissions. It directly affects federal environmental policy by challenging the EPA's current regulatory scope on climate-related emissions.
