The Supreme Court’s Latest Decision Is a Blow to Stopping Climate Change

Union of Concerned Scientists

Had the court ruled fully in favor of the EPA— or not taken the case at all —a much more meaningful dent in power plant carbon emissions would be within reach, while also delivering much greater reductions in other dangerous co-pollutants from burning fossil fuels such as particulate matter, mercury, nitrogen oxides and sulfur dioxide.

Don’t Believe the Lies: Five Facts to Consider as the UN’s COP27 Comes to a Close

Union of Concerned Scientists

A few critical points puncture the industry’s empty rhetoric: When hydrogen is burned, it can emit as many nitrogen oxides as natural gas combustion —if not more —which can cause significant respiratory health problems. degrees goal is threatened by political inaction. Why not just start with renewables?

Why UCS Supporters Are Pressing EPA to Let California Enforce Its Truck Pollution Rules

Union of Concerned Scientists

California’s leadership on reducing truck pollution has been on full display the past few years, passing critical regulations requiring 90 percent reduction in smog-forming nitrogen oxide (NO X ) emissions from diesel trucks and requiring manufacturers sell an increasing share of electric trucks to move away from fossil fuels altogether.

New Analysis Shows Truck Manufacturers’ Scare Tactic Just a Bunch of Hot Air

Union of Concerned Scientists

Primarily, these have focused on the 2007 EPA regulations, which were the first step in the phase-in of diesel engine standards meant to cut particulate emissions by more than 80 percent and smog-forming nitrogen oxides (NO X ) emissions by 90 percent. It’s not clear whether such late-breaking support will be enough.

Accelerating Freight Decarbonization

Legal Planet

The emissions from these trucks, such as particulate matter & nitrogen oxides, can contribute to poor air quality in these communities. This target has been incorporated into the National Climate Agreement, a binding law that ensures political commitment to implementation.

RePlanet Nederland letter to the EU Commission about the sustainable finance taxonomy

Environmental Progress

Nuclear energy has very low NOx (nitrogen oxides), SO2 (sulphur dioxide), PM (particulate matter) and NMVOC (non-methane volatile organic compounds) emissions. The values are comparable to or better than the corresponding emissions from the solar PV and wind energy chains.
