The RPM Act – How a Multi-billion Dollar Industry is Trying to Ruin Our Air

, senior vehicles analyst

With “defeat devices” once again in the news, thanks to yet another manufacturer failing to comply with the Clean Air Act, now seems as good a time as any to remind folks how the automotive industry is actively working to undermine the protections of the Clean Air Act and increase the use of defeat devices in passenger cars and trucks. 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.

Why UCS Is Suing Trump Over Car Standards

, president

On September 27, the Trump administration issued a new rule that purports to take away the right of California and thirteen other states to cut carbon dioxide emissions from cars and light duty trucks and require increasing percentages of new car sales to be electric vehicles or other zero emitting technology.

Today, the Union of Concerned Scientists filed suit against the Trump administration for this action. UCS does not typically file lawsuits that focus on the legal authority of states and the federal government. But this suit is about much more than that. Read more >

Hurricane Season’s Impact at the Pump and Why Fuel Efficiency Matters

, research and deputy director, Clean Vehicles

Gas prices are spiking. This week EIA reported an increase in the average price of gasoline of 28 cents per gallon – with some states seeing more than 40 cent increases. That’s the largest nationwide weekly gas price increase since hurricane Katrina in 2005.

What’s 28 cents worth you ask? More than a $100 million a day it turns out.

That’s bad, but it could be worse. Without vehicle fuel efficiency and emission standards that are currently in place, American drivers would be paying an average of $50 million more per day on fuel costs.
