No, EVs are Not Worse for the Planet
There’s an electric car culture war raging. It doesn’t hurt to say obvious things, like that electric cars reduce driving costs and pollute far less than gas-powered cars.
If you have somehow managed to escape the frenzied political headlines about electric vehicles, first I envy you and second, I must regrettably inform you that the EV has become an acronym of partisan rancor on par with IVF, DEI, and CRT. There’s a lot of reasons for this electric car culture war: President Biden …

CONTINUE READINGThe New EPA Car Rule Doesn’t Violate the Major Questions Doctrine
They both relate to climate, but West Virginia v. EPA involved a very different regulation raising very different issues.
In West Virginia v. EPA, the Supreme Court struck down the Obama-era Clean Power Plan. The heart of the ruling was that EPA had engaged in a power grab, basing an unprecedented expansion of its regulatory authority on an obscure provision of the statute. Conservative groups have claimed since then that virtually every government regulation …

CONTINUE READINGThe New Particulate Standard and the Courts
The tough new air quality standard is sure to be challenged in court. Winning the challenges will be tougher.
EPA has just issued a rule tightening the air quality standard for PM2.5 — the tiny particles most dangerous to health — from an annual average of 12 μg/m³ (micrograms per cubic meter) down to 9 μg/m³. EPA estimates that, by the time the rule goes into effect in 2032, it will avoid 4500 premature …

CONTINUE READINGInequality Today: Unfinished Work
The first step in addressing the problem is to be clear about the facts.
More than a half century after Martin Luther King’s death, his work is still unfinished. Sadly, despite his efforts and those of many others, inequality remains a reality along multiple, interrelated dimensions: race, income, and geography. Inequality is not merely economic; it involves differences in health and life expectancy — and in exposure to pollution …

CONTINUE READINGThe Mystery of the Missing Stay Order
Why is the Supreme Court waiting for weeks to dispose of a demand for extraordinary intervention in a routine situation?
The steel industry applied for Supreme Court intervention on what they claimed was an urgent issue of vast national importance. Chief Justice Roberts requested an immediate government response. That was six weeks ago. Since then . . . crickets. No doubt you’re on the edge of your seat, wondering about the impending crisis facing the …

CONTINUE READINGEvolving Air Quality Standards
The standards have gotten tougher. Compliance still lags.
The goal of the Clean Air Act is to achieve national ambient air quality standards (NAAQS), with the primary requirement being protection of public health. As our understanding of the health effects of air pollution has improved, there has been a general trend toward tightening the standards. However, it’s very hard to keep track of …

CONTINUE READINGWhat’s Been Killing U.S. Coal?
No, it’s not Biden. Or EPA. The culprits are supply and demand.
From 1960 to 2005, coal use grew more or less steadily by 18 million tons per year. It then tread water for a few years and began a steep decline in 2008, going from half of U.S. electricity to about one-fifth today. What happened in the middle of the Bush Administration to halt growth? And …

A leading environmental lawyer gives his perspective.
Transportation is now the source of 28% of U.S. greenhouse gas emissions, more than the electric power sector. The transportation sector is also a substantial source of nitrogen oxides and particulates, both of which are dangerous to human health. The Biden Administration has taken important regulatory actions bearing on these problems, with others in the …

CONTINUE READINGCars, Smog, and EPA
Over the past fifty years, EPA has overseen incredible reductions in auto pollution.
This is part of an occasional series of posts about the evolution of pollution standards. Today’s subject is pollution control for new vehicles, which have been known to cause smog since the 1960s. The history of these pollution standards is quite distinctive. At the high temperatures in internal combustion engines, some of the nitrogen in …

CONTINUE READINGState Air Regulations Can Go Above and Beyond National Standards
State and local regulators can and should work to reduce particulate matter, ozone, and NOx emissions even when national standards are met.
States and local air quality regulators have the legal authority to set particulate matter (PM), ozone, and nitrogen oxides (NOx) emissions standards and adopt regulations for these pollutants when they are already in attainment of the national ambient air quality standards (NAAQS) set by the U.S. Environmental Protection Agency (EPA) under the federal Clean Air …
