TCI Health Study Shows Benefits, But More Needed to Address Inequitable Air Pollution

, Senior vehicles engineer

Communities across the Northeast and Mid-Atlantic region of the U.S. could see substantial health improvements from just modest changes in air quality, according to a new preliminary study released by a team of researchers from the Harvard T. H. Chan School of Public Health, Boston University School of Public Health and the University of North Carolina. By investing in clean transportation solutions such as enhanced transit, safe and bikeable streets, and vehicle electrification, states in the region would not only experience lower greenhouse gas emissions, but also a drop in local air pollution. At a time when clean air is desperately needed, the health benefits of the proposed program are a step in the right direction, but we will need significant complementary policies to bring us into a truly equitable clean transportation future.

Why is the Transition to Clean Cars by 2035 Critical? To Avoid Worsening Impacts of Climate Change and Air Pollution

, Senior vehicles engineer

California is already seeing the impact of climate change, with droughts, heat waves, and of course the unprecedented wildfires seen this summer. If the state follows through on the recent announcement from California’s Governor Newsom setting a target of 100% zero emission new car sales by 2035 and other states and countries follow, we can avoid even worse impacts of climate change.

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.

Uber and Lyft Are Harassing a Researcher, Pulling a Page from Climate Deniers’ Playbook

, Research Director, Center for Science and Democracy

Don’t like the message that research findings bring? Attack the researcher. At least that’s the strategy that industries and ideologues have used for years to intimidate and silence scientists when their results are inconvenient. Now, Uber, Lyft, and Door Dash are joining the likes of fossil fuel interests, chemical companies, and pharmaceutical giants in endorsing the bullying of researchers to protect their own profits.
