In the absence of legislation, critical long-distance transmission can be developed by applying existing federal legal authorities. A number of important regulatory and commercial measures have been proposed, including streamlining transmission planning, upgrading existing transmission system components, putting transmission lines underground, and using existing rights-of-way from highways and railroads. Even if these solutions are adopted, however, state siting requirements may prove an important obstacle to developing an efficient, national transmission grid. So, this paper examines legal authorities already available to the Department of Energy and the Federal Energy Regulatory Commission to develop the interstate transmission capacity crucial to the energy transition.

To ensure policies are based on accurate predictions of climate impacts, it is critical to understand social-ecological system (SES) feedbacks, including how humans change the climate by reacting to a changing climate. Building on recent scholarly work on the topic, this article describes SES interactions and how they can be incorporated into climate policy tools such as the social cost of carbon. The article then proposes a research agenda for the identification, quantification, and integration of climate-society feedbacks into social-cost integrated assessment models (SC-IAMs).

To achieve the Biden administration’s ambitious commitments to equity and environmental justice, agencies will need guidance on how to assess and weigh the distributional effects of policy options. This report recommends steps that the Office of Management and Budget (OMB) can take to mainstream equity into agencies’ decisionmaking.

The typical starting point and centerpiece of energy decarbonization is the electric power sector, a large direct GHG emitter. Published in The Electricity Journal, this paper explores what the modeling community should do to inform this transition, including expanding energy market datasets and designing models that incorporate multiple objectives and manifold actors behaving strategically in a framework consisting of large uncertainty, while accounting for the physics of power systems.

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.

This report identifies best practices EPA should adopt to holistically assess and weigh the costs and benefits of risk management options, allowing the agency to meet its statutory obligations and best enhance public welfare.

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.
