Leasing public lands and waters for fossil-fuel extraction drives a quarter of U.S. carbon dioxide emissions. Our new report offers analytic tools for federal leasing decisions to drive policies that maximize economic and environmental welfare—nationally and locally.

The February 2021 blackout in Texas underscored the importance of reliable and resilient power systems. This article discusses the roles of regulators, markets, fuel and generation supply chains, and interdependent infrastructures, and finds that they need to be reconsidered and redefined to successfully meet the future challenges of increased electrification and severe weather

Federal agencies will need to offer considered and detailed responses to objections raised in the notice-and-comment processes for individual regulations or administrative actions that apply the Working Group’s social cost valuations. Given its expertise, the Working Group should consider providing such responses now, so that agencies can then incorporate them into future actions. This working paper offers a blueprint for those responses.

The Interagency Working Group on the Social Cost of Greenhouse Gases can use the findings from expert elicitations to improve the U.S. federal government’s social cost of greenhouse gas estimates, which are used in regulatory cost-benefit analysis and other policy contexts. Our report highlights several component updates, incorporating data from expert elicitations, that the Working Group should consider during its current update of the social cost of greenhouse gas estimates.

In light of recent evidence, a new range of discount rates appropriate for calculating the social cost of greenhouse gases could be conservatively estimated as between 0.5%-2.5%, with a central estimate of 1.5%. Agencies should follow the Interagency Working Group’s guidance on applying new social cost of greenhouse gas estimates based on updated discount rates—and will need to justify their choices, including any departures from prior practices.
