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.

California Moves Forward to Address Pollution from Heavy-Duty Trucks

, senior vehicles analyst

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 >

Old Laws, New Science, and Protecting Public Health: The Trump Administration’s Decision on Particulate Pollution Standards

, Research Director, Center for Science and Democracy

In June, the public comment period closed on the EPA’s draft rule on the National Ambient Air Quality Standards for Particulate Matter. Now we wait, as the agency reviews the more than 66,000 public comments submitted and Trump leadership at EPA rushes to finalize the rule by its own arbitrary deadline of the end of 2020. Here’s a rundown of the state of play, and where I and the Union of Concerned Scientists stand on the nation’s protections against one of the most common and harmful air pollutants in the US.

The EPA Is Set To Ignore Science and Risk Your Health on Particulate Pollution: Your Voice Needed

, Research Director, Center for Science and Democracy

The Trump Administration is set to ignore science and risk your health on an air pollution rule that will affect millions of people in the US. By June 29, we need the voices of scientists and members of the public to tell the EPA and the Trump Administration that our particulate matter (PM) standards must protect public health, as the Clean Air Act requires. Here’s a list of top points it would be useful to make in public comments. Read more >
