New rules from the U.S. Environmental Protection Agency to reduce mercury and other toxic air emissions will affect dozens of antiquated power plants currently operating without pollution controls. These
rules have stirred debate in some circles as to whether retrofitting or retiring outdated plants will cause shortfalls in electricity capacity. How will EPA mercury rules influence the electricity system? This fact sheet updates earlier assessments by taking a close look at recent studies on the reliability of the electricity grid to answer that question.
The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Transportation (DOT) announced today a joint proposal to set stronger fuel economy and greenhouse gas pollution standards for model year 2017-2025 passenger cars and light trucks.
Earlier this week, the U.S. Environmental Protection Agency (EPA) sent proposed greenhouse gas emissions standards for new and modified power plants to the Office of Management and Budget (OMB) for review.
Economist Frank Ackerman has called the “social cost of carbon” the most important number you never heard of. What is the social cost of carbon, where do the numbers come from, and why should policymakers take care when using them?
This policy brief explains the various steps in calculating the social cost of carbon, the weaknesses and strengths of those calculations, and how they are used to inform climate policy. The aim is to help policymakers, regulators, civil society, and others judge for themselves the reliability of using the resulting numbers in making policy decisions.
WRI works to inform Congress about the opportunities and impacts of legislative proposals that affect U.S. greenhouse gas emissions and to help shape federal policies that will lead the U.S. on a path of low-carbon growth.
