Livestock Operations Are Responsible for Over Half of California’s Methane Emissions—Why Won’t CARB Regulate Them?
CARB will have the authority to regulate methane from livestock operations beginning in January but has not initiated rulemaking
At a recent California Air Resources Board (CARB) meeting, a staff member responded to a question about why CARB’s program for reducing emissions from transportation fuels incentivized the capture of methane from landfills so much less than the capture of methane from dairies: “Landfills have a different CI [carbon intensity] score because they are …

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 …

Three big cases in the D.C. Circuit will determine the fate of Biden’s vehicle regulations.
This week, the D.C. Circuit hears three cases challenging use of federal regulations to push adoption of electric vehicles and to allow California to forge path toward zero-emission cars. If all three cases go badly, the regulatory system would be disabled from playing a role in this area. This would be a huge setback, though …

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 …

These three power plants cause a big share of America’s mercury pollution.
In Ireland, poor people used to burn peat from fuel. Barely a step ahead of that, some American power plants burn semi-fossilized peat (lignite) to run their generators. It turns out that those power plants produce about a third of all the toxic mercury emissions of the entire industry. Even more remarkably, about half of …

Court Decision May Well Be Correct as a Matter of Law, But Represents Outdated & Unsound Public Policy
Last week, the California Supreme Court unanimously ruled that a local initiative measure that would have imposed severe restrictions on oil and gas development in Monterey County is preempted by state law and therefore invalid. The decision came in the case of Chevron U.S.A., Inc. v. County of Monterey. The Supreme Court’s ruling was predictable, …
CONTINUE READINGBiden’s Proposed Power Plant Rule is a Solid First Step
The electric power sector remains 30 percent of the nation’s carbon dioxide emissions, and this rule can incentivize the push towards renewables.
On May 23, the Environmental Protection Agency (“EPA”) proposed emission limits and guidelines for carbon dioxide from fossil fuel-powered plants. To avoid the same fate as the Obama Administration’s Clean Power Plan, which was struck down by the conservative Supreme Court in West Virginia v. EPA last year, the new draft rule does not determine …

The benefits of the energy transition transcend climate.
The main reason to control carbon is to protect the climate. But cleaning up the energy system has plenty of other benefits. Those benefits will flow to people in rural areas as well as urban ones, to national security and international development, and to nature itself. To begin with, there are the health benefits of …

CONTINUE READINGLocal Authority Over Oil Drilling Heads to California Supreme Court
Cities and counties have long held authority to decide where and whether to allow oil and gas exploration and extraction. The state’s high court can make that crystal clear.
If California residents decide by voter initiative to limit land uses for oil and gas extraction in their county, can fossil fuel businesses turn around and claim state preemption to overturn the voice of the voters? That’s what is at issue in a case that’s headed to the State Supreme Court. Oral arguments in this …
