Given the vast uncertainty surrounding climate impacts, meta-analyses of global climate damage estimates are a key tool for determining the relationship between temperature and climate damages. Due to limited data availability, previous meta-analyses of global climate damages potentially suffered from multiple sources of coefficient and standard error bias. To address and test for these biases, we expand on previous datasets to obtain sufficient degrees of freedom to make the necessary model adjustments, including dropping duplicate estimates and including methodological variables. Estimating the relationship between temperature and climate damages using weighted least squares with cluster-robust standard errors, we find strong evidence that duplicate and omitted variable biases flatten the relationship. However, the magnitude of the bias greatly depends on the treatment of speculative high-temperature (>4 ◦C) damage estimates. Replacing the DICE-2013R damage function with our preferred estimate of the temperature–damage relationship, we find a three- to four-fold increase in the 2015 SCC relative to DICE, depending on the treatment of productivity. When catastrophic impacts are also factored in, the SCC increases by four- to five-fold.

Budget cuts threaten EPA’s ability to enforce federal environmental laws, and states have neither the means nor the will to substitute for it. Our issue brief on EPA enforcement explores the financial and political constraints that state regulators already face when implementing federal environmental laws and how the Trump Administration’s budget cuts would exacerbate these problems.

The Midnight Rules Relief Act, approved by the Senate’s Homeland Security and Governmental Affairs Committee on May 17, 2017, would turn the Congressional Review Act (“CRA”) from a scalpel into a sledgehammer. Our issue brief describes how this shift in regulatory policy would allow for quick repeals of public safeguards after only 10 hours of Senate debate and prevent similar rules from being enacted in the future.

The Regulations from the Executive in Need of Scrutiny Act (“REINS Act”) would prevent agencies from issuing statutorily required rules unless approved by Congress. Our issue brief describes how this bill would create substantial burdens for Congress, worsen outcomes for the American public, and raise constitutional red flags by allowing Congress to repeal earlier statutes through inaction.

The Senate’s Regulatory Accountability Act would rewrite notice-and-comment rulemaking procedures and create extraordinarily burdensome hurdles in rule implementation by requiring trial-like public hearings. Our issue brief describes how this change to regulatory reform would give opponents of major public safeguards a valuable tool to delay implementation for years, without any regard to the harm that delay would impose on the health and safety of the American public.

To solve the unprecedented global commons problem posed by climate change, all nations must internalize the global externalities of their emissions. If not, collective efforts will never achieve an efficient, stable climate outcome. The United States’ practice of looking at the global impact of emissions has come under attack in courtrooms and academic journals, with some arguing that the U.S. should instead consider only the domestic impacts of climate change in its decisionmaking.

In a letter published in Review of Environmental Economics and Policy, we argue that federal agencies should continue to use a global number for Social Cost of Carbon, as developed by the Interagency Working Group on Social Cost of Carbon. First, the United States benefits tremendously if other countries set policy based on global rather than local effects. From a legal perspective, not only does international law—the U.N. Framework Convention on Climate Change—commit the United States to account for global effects, but domestic laws like the Clean Air Act and the National Environmental Policy Act also either require or give discretion to agencies to consider global climate costs. Many seemingly “foreign” climate damages would actually spill over to harm the United States.

Scientific studies show that climate change will have, and in some cases has already had, severe consequences for society, like the spread of disease, increased food insecurity, and coastal destruction. The social cost of carbon (SCC) is a metric designed to quantify climate damages, representing the net economic cost of carbon dioxide emissions. Our issue brief on the Social Cost of Carbon details how this metric was developed and how it applies to federal regulatory policy.

Our issue brief on Jobs and Environmental Regulation addresses rhetoric on “job-killing regulations,” describing the lack of consistent evidence that regulations lead to long-term changes in the unemployment rate. It also provides information on how to analyze claims about job impacts.

Our issue brief on Regulatory Co-Benefits analyzes the importance of using unbiased economic analysis to consider all direct and indirect costs and benefits of any environmental safeguard.

This report contains a set of recommendations for the Trump Administration that, if implemented, would strengthen the process of regulatory review. These recommendations reflect the general consensus of a group of former Administrators and Acting Administrators from the Office of Information and Regulatory Affairs who served under both political parties.
