Good News—and Bad—about Fossil Fuel Power Plants in 2023 

Union of Concerned Scientists

And fossil fuel power plants may not stick to their retirement schedules for a variety of reasons. NO x also contributes to the formation of ozone (or “smog”), another toxic pollutant. A bit more on those reasons later. A recent study found that more than 99 percent of the global population is exposed to unsafe levels of PM 2.5

Improving EPA’s Latest Ozone Transport Rule

Acoel

EPA’s latest proposed rule targeting NOx emissions from fossil-fueled electric generating units (EGUs) is a classic study of diminishing returns. The agency’s air quality modeling indicates that most areas would receive an ozone reduction of less than 0.1 enjoyed ozone reductions of 3 to 5 ppb or more.

EPA’s Power Plant Carbon Rules Are Critical—and Complex. Here’s What to Know, and What to Watch.

Union of Concerned Scientists

The IRA gave us effective tools for cleaning up the power sector through dedicated support for the rapid and widescale deployment of renewable resources and the technologies that support them. Which means the consequences of these polluters unabashedly continuing to pollute aren’t just severe—they’re compounding.

Unraveling LA’s Hydrogen Combustion Experiment

Legal Planet

But with the recent influx of government incentives for hydrogen production, new and improving production and storage technologies, and greater political will than ever before, H 2 ’s reputation is gaining favor. But for many of these use-cases, hydrogen doesn’t do the job particularly well, at least as compared to existing technology.

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

Environmental Progress

The analyses did not reveal any science-based evidence that nuclear energy does more harm to human health or to the environment than other electricity production technologies already included in the Taxonomy as activities. The European Commission commissioned a thorough review of nuclear energy by the Joint Research Centre (JRC).

Glossary of Greenhouse Gas Terms

Greenbuilding Law

With proposed federal regulation of greenhouse gas emissions by the Securities and Exchange Commission requiring GHG disclosure and new state statutes, including a new Maryland law that requires not only disclosure, but also a mandated reduction in GHG emissions, a greater appreciation of the subject of GHG appears in order.
