7 Reasons California Should Get Tougher on Methane from Dairies
California lawmakers should rethink the role of dairy digesters in the state’s dairy and livestock mitigation strategy.
Even though California aims to decrease the emissions of methane, dairy operations are rewarded for creating, and capturing, more and more of the planet-warming super pollutant in the form of manure-derived biogas. Today, California lawmakers declined to correct that perverse incentive, but they still have opportunities to rethink the state’s embrace of digesters as its …

CONTINUE READINGThe Unique Legal Context of EPA Methane Regulations
Three separate congressional actions intersect to support the regulations.
The government’s efforts to control methane have followed a complicated path, involving three different congressional actions: section 111 of the Clean Air Act, which allows EPA to regulate emissions of greenhouse gases; a congressional override of an earlier regulatory action; and a newer statute that creates a fee on methane emissions. The upshot is to …

Numerous Key Environmental Issues and Doctrines Will Confront the Justices This Year
As we begin 2024, it’s useful to identify and assess the many environmental issues that the U.S. Supreme Court has agreed to decide this year. It seems likely that the conservative majority of the justices will erode or, perhaps, dramatically jettison longstanding principles of environmental law and policy in the coming months. Summarized below are …

Guest Contributor Meleana Chun-Moy reflects on COP28 and the growing recognition of the intersection between the climate crisis and human health.
The climate crisis is a public health crisis, and it finally seems global leaders have recognized that fact. With the backdrop of the first-ever Health Day at the annual UN climate conference, air quality in Dubai soared, as PM2.5 pollution reached 155 micrograms per cubic unit. The World Health Organization states the annual average concentrations …

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 …

Nations, companies, and NGOs are targeting methane like never before using satellite data. A new UCLA paper outlines what that could mean for regulation.
Methane is ready for its close-up. The first week of COP28, the UN climate talks taking place in Dubai, saw a handful of big announcements about how world leaders plan to tackle human-made climate change by targeting methane, a powerful short-term climate pollutant. The UCLA Emmett Institute is also drawing attention to the issue of …

One of these things is not like the others.
The automotive world is changing quickly. Most of the trends are mutually reinforcing. But one points in the opposite direction. The first and most obvious trend is the rise of EVs. In the twenty years since Tesla arrived, EVs have gone from 0.2% of new cars to 13%, and Bloomberg predicts that this figure will …

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 …

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 …
