Wisconsin moves to scrap 40-year-old vehicle emissions testing rules

Wisconsin lawmakers are pushing to end the state's long-running vehicle emissions testing programme. Congressman Tom Tiffany, a gubernatorial candidate, argues the scheme is outdated and wastes resources. He plans to work with the US Environmental Protection Agency (EPA) to scrap the requirement in seven counties. The emissions testing programme has been in place since 1984 for counties designated as non-attainment zones under the Clean Air Act. Over nearly four decades, it has cost residents an estimated £216 million. Yet failure rates remain low, with just 3.1% in 2021 and 3.0% in 2022.

Critics say the tests no longer make sense. Matt Leppard, a repair shop owner, claims they hurt the used car market and force families into expensive repairs. Bob Donovan, a Wisconsin representative, agrees, pointing to widespread resident frustration. He argues people are willing to follow rules—but only if they seem reasonable. Tiffany dismisses calls for repair subsidies as another burden on taxpayers. Instead, he wants to redirect funds to other environmental projects. His proposal would require changes to federal Clean Air Act rules, meaning EPA approval is essential.

The programme's future now depends on negotiations with the EPA. If successful, ending testing could save residents money and shift resources elsewhere. For now, the seven affected counties must still comply with the decades-old requirement.
