Under Biden Administration, a New Decade Has Dawned—Passenger Car Regulations Must Keep Up

With a new administration taking office and a new decade upon us, it’s a perfect opportunity to recommit to holding the automobile industry accountable under the Clean Air Act. While manufacturers continue to be in compliance with fuel economy and emissions regulations, improvements are stalling, and a continued shift away from cars to SUVs and light trucks shows the country progressing far too slowly to avert the worst impacts of climate change. With a new presidential administration set to take over, it’s time to put the previous administration’s rollback in the rear-view and the pedal to the metal, pushing industry onto a more sustainable path.

Last week, General Motors announced it’s ending its part in the lawsuit supporting the Trump administration’s illegal elimination of California’s ability to set global warming emissions standards for passenger cars and trucks. While the news is a welcome action and something UCS and others have been pressuring GM to do, done in the wake of the election of a new president, it screams of political expediency, not environmental leadership.

In this case, aftermarket parts manufacturers and dealers, under their trade association, are fighting for passage of the Recognizing Protection of Motorsports (RPM) Act, a bill which would cripple EPA’s ability to go after people who tamper with automotive emissions controls and one UCS has been tracking for more than three years. Since the industry continues to push this bill in session after session of Congress, let’s break down what the RPM Act does, why it keeps coming back, and why this zombie bill should be taken out and never be heard from again.

California Moves Forward to Address Pollution from Heavy-Duty Trucks

The San Joaquin Valley and Southern California continue to have the worst air quality in country, in terms of both smog and particulate pollution (soot). Next Thursday, the California Air Resources Board (CARB) will vote a proposal to reduce smog-forming and soot emissions from heavy-duty vehicles sold in the state over the next decade. This latest proposal is a critical part of cleaning up the trucking sector until that broader transformation takes place. Read more >

EPA Made So Many Mistakes with Clean Cars Rollback, Even Its Own Lawyers Want to Know What’s Up

On Monday, EPA’s Office of Inspector General (OIG) announced an investigation into the so-called “SAFE” rule, which rolled back Obama-era global warming emissions and fuel economy standards and will cost both consumers and the environment. This investigation is just the latest example of the many ways in which the administration’s attempts to cut corners and ignore science are being challenged.
