Bottom Line on State and Federal Policy Roles

This briefing explores the debate over whether the United States should adopt a single federal climate policy, allow states to lead with individual policies, or utilize a joint approach. It analyzes the rationales for each model, the likelihood of federal preemption of state authority, and the implications for businesses operating across multiple jurisdictions.

• Advocates for a single federal climate policy argue it would create a "level playing field for all businesses" and simplify compliance for corporations by replacing multiple jurisdictional regulations with a uniform standard. Furthermore, a strong federal policy is viewed as capable of achieving greater emission reductions than state-led actions alone, as not all states would implement their own policies.
• The rationale for state-led climate policy is that states can act as "laboratories for developing new, innovative policies" and typically implement new ideas faster than the federal government. State-level action is also seen as a catalyst for federal action and allows for policies tailored to specific geography, natural resources, and stakeholder interests.
• A joint policy approach, where the federal government sets a minimum standard that states may exceed, is presented as a likely outcome based on the history of U.S. environmental policy. This cooperative model aims to capitalize on the strengths of both government levels and provide businesses with more stability than a scenario where states act independently.
• Full federal preemption of state and local authority is rare; partial preemption is more common. While federal legislation could potentially prohibit states from implementing any GHG regulations, it is unlikely that states would be prevented from regulating sources that the federal government does not cover.
• State-level climate policies create both challenges and opportunities for businesses. While differing state regulations increase compliance costs, renewable energy mandates and incentives have allowed businesses to adopt green technologies and reduce "vulnerability to fossil fuel price volatility," while also catalyzing new industries.
