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.

EPA Proposal to Rescind Oil and Gas Methane Regulations Has Not Been Adequately Justified and Disregards Negative Climate Impacts

Columbia Climate Law

The emissions make a significant contribution to climate change because methane is a highly potent greenhouse gas which, in the first 20 years after it is released, traps approximately 84 times more heat in the earth’s atmosphere than carbon dioxide (on a per ton basis).

These Attorneys General Are Defending the Fossil Fuel Industry, Not Their States

Union of Concerned Scientists

In 2015, when he took office as AG after stints in the Texas Legislature, he sued the Environmental Protection Agency for strengthening a standard for ground-level ozone, better known as smog. By railing against what he calls a “radical climate change movement” and suing the federal government to protect corporate polluters.
