Oil Refineries: A Deadly Industry

Union of Concerned Scientists

One good example of the nexus between global warming and local pollution is ground-level ozone. It has been estimated that globally oil processing is responsible for about 15 percent of all VOCs released into the atmosphere. To make matters worse, NOx contributes to the formation of ground-level ozone and secondary PM2.5,

Project 2025’s Assault on EPA, Human Health and the Environment Must Never Be Put into Action

Union of Concerned Scientists

This, along with many other chemicals, like diesel particulates and ground-level ozone that form soot and smog, and metals like lead in paint and drinking water, are regulated by the EPA to keep us safe. PFAS is shorthand for a class of “forever chemicals” that persist in the environment indefinitely.

In a Blow to Public Health, EPA Delays Strengthening Ozone Standards

Union of Concerned Scientists

Despite clear recommendations from its own science advisors, the US Environmental Protection Agency (EPA) announced over the summer that it will delay its scheduled process to consider strengthening public health standards for ground-level ozone pollution. The stakes over ground-level ozone standard are high.
