California’s EPA-approved mandate to ban the sale of new gas-powered cars and light trucks by 2035 is creating ripples across the nation, including Wisconsin. Under the Clean Air Act, California has a unique waiver, approved by Biden’s EPA, allowing it to enforce stricter vehicle emissions standards than the federal government. Automakers often align their production with California’s rules, extending its influence well beyond its borders.
In 2022, the California Air Resources Board (CARB) launched its Advanced Clean Cars II Regulations (ACC II), targeting a 35% sales requirement for zero-emission vehicles by 2026 and a full phase-out of new gas-powered cars by 2035. While California Governor Gavin Newsom praised the EPA’s approval as a step toward cutting pollution and combating climate change, critics argue that the move grants California outsized power to shape national policy.
Wisconsin’s Republican Legislature recognized this risk and passed a bill designed to protect the state from similar restrictions. The legislation passed last session would have ensured that Wisconsin retained control over its vehicle market, shielding consumers from potential limitations on their choices. However, Governor Tony Evers vetoed the measure, leaving Wisconsin exposed to external pressures from policies like California’s.
In his veto message, Governor Tony Evers, cites his objection to permanently limiting the ability of state agencies and local governments to adapt to “evolving energy technologies.” Evers emphasized that as clean energy innovations become more accessible, cost-efficient, and competitive, Wisconsin should be embracing these advancements to meet the demands of a 21st-century economy. He argued that the bill would hinder the state’s ability to address consumer needs, combat climate change, and transition to innovative industries and technologies. Additionally, Evers criticized the Legislature’s efforts to preempt local control, asserting that the state should act as a supportive partner, not an obstacle, in helping local governments address their unique challenges.
President-elect Donald Trump has been a vocal critic of California’s waiver system, emphasizing that states should not dictate national standards. During his previous administration, Trump blocked California’s auto emission rule, citing concerns about regulatory confusion and economic consequences. His incoming administration is expected to revisit these policies, prioritizing consumer choice and state autonomy.
Evers’ veto highlights a growing debate about the balance between state rights and federal authority, particularly as California’s environmental policies set a de facto standard for the automotive industry. For Wisconsin residents and businesses, the stakes are significant. Without protections, Wisconsin could face downstream effects from California’s rules, including limited vehicle options and higher costs.
As the Trump administration works to challenge California’s regulatory power, Wisconsin lawmakers may need to reconsider how to safeguard the state’s interests and ensure that policies reflect local priorities—not those imposed by another state. Wisconsin State Assemblyman, Rep. Tyler August has vowed to bring this legislation back in the upcoming legislation session.
