Estimating the social cost of carbon

Reconsidering the social cost of carbon

Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us.

In this episode, Frances Moore presents a re-analysis of how the social costs of carbon emissions are quantified.
