Regulations to curtail climate change have the additional benefit of reducing air pollution by accelerating the shift away from carbon-intensive and high-polluting energy such as coal. The benefits from reducing just one air pollutant – particulate matter – account for almost half of the quantified benefits of the Obama Administration’s Clean Power Plan. Regulatory opponents have launched an aggressive attack on the use of these benefits to justify climate change regulations. They claim that these benefits are not real, are accounted for in other regulations, or should not be considered because they are indirect benefits. This article, published in the Minnesota Law Review, collects and analyzes for the first time the robust support for valuing particulate matter and other air pollution reduction benefits. Following an examination of the scientific literature, longstanding agency practices under administrations of both major political parties, and judicial precedent, the authors conclude that particulate matter benefits deserve a meaningful role in regulatory cost-benefit analysis.

When federal and state policymakers account for the impacts of climate change, they regularly use a tool called the Social Cost of Carbon (SCC). The SCC puts a dollar value on the most significant, quantifiable damages caused by each additional ton of carbon dioxide emitted. The most recent estimate of the cost is at least $51 per ton and rising over time. But now, turning its back on years of work, the Trump administration has disbanded the federal group that developed the SCC, and produced a new “interim” estimate claiming that each ton of carbon dioxide causes as little as $1 in climate damages. This issue brief describes how the Trump Administration reached this misleading number by ignoring the interconnected, global nature of our climate-vulnerable economy and obscuring the devastating effects that climate change will have on younger and future generations. Though the administration has been proposing rollbacks of environmental rules using this problematic SCC estimate as justification, we explain why federal agencies and state governments should continue using the most recent estimate by the Interagency Working Group that developed the SCC.

Distributed energy resources (DERs)—grid-connected, small-scale electric generators such as rooftop solar installations, micro-turbines, combined heat and power systems, customer backup generators, and distributed energy storage systems—are a growing part of the U.S. electric system. They can help avoid the high levels of greenhouse gases and local air pollution produced by traditional energy sources. As their use grows, state electric utility regulators are seeking to compensate DERs accurately for the benefits they offer, including reductions in pollution that contributes to climate change and harms human health. This report shows how regulators can calculate the types and amount of pollution avoided, and then monetize these benefits for use in policy.

Recent advances in technology and the consequent decline in manufacturing costs are making energy storage systems a central element of energy and climate change policy debates across the nation. Energy storage systems have the potential to provide many benefits such as lower electricity prices at peak demand times, deferred or avoided new capacity investments, and reduced greenhouse gas emissions. Indeed, both federal and state policymakers are enthusiastically encouraging more energy storage deployment with the belief that energy storage systems will help reduce greenhouse gas emissions from the electricity sector by making intermittent and variable renewable energy resources such as solar and wind more attractive. This article, published in the Harvard Environmental Law Review, challenges this common assumption that increased energy storage will necessarily reduce greenhouse gas emissions.

The article was selected by Environmental Law Reporter as one of the five best environmental law articles published during the 2018-2019 academic year. An adapted version, The Future of Energy Storage: Adopting Policies for a Cleaner Grid, was included in the August 2019 Environmental Law and Policy Annual Review issue of Environmental Law Reporter’s News & Analysis.

Most regulations seek to improve social welfare, but maximizing overall welfare may not help or protect all groups evenly. Many economists suggest handling unequal regulatory effects through the tax system. But some harms—like the disproportionately high environmental pollution felt by poor and minority communities and loss of the employment base in rural communities due to shifts in the economy—cannot be addressed by monetary compensation alone. A new article by Richard Revesz, published in the NYU Law Review, offers a blueprint for establishing a standing, broadly constituted interagency body charged with addressing serious negative consequences of regulatory measures on particular groups.
