Managing forests for CO2 reduction

A new US Department of Energy report coauthored by Yale School of the Environment (YSE) scientists lays out a pathway to remove at least 1 billion tonnes of carbon dioxide per year from the atmosphere by 2050 and storing it on a gigaton scale—a figure that is needed to reach the Biden administration’s net-zero emissions goals and avoid the worst impacts of climate change. A key component of this pathway centers on forests, which have the potential to yield a cumulative removal of 1.5 to 1.8 billion tonnes of carbon dioxide equivalent (CO2e) by 2050 with careful intervention and management, YSE scientists say.

YSE professor clarifies costs of addressing climate change

How much will it cost to meaningfully reduce greenhouse gas emissions on a global scale? The answer, according to a new analysis coauthored by Matthew Kotchen, professor of economics at the Yale School of the Environment, is that it depends on who’s doing the calculation.

In a new study published in Science, Kotchen and coauthors James Rising, assistant professor at the University of Delaware, and Gernot Wagner, Columbia University climate economist, map out a large discrepancy in the two core modeling approaches that are used today, and suggest four ways to move forward to resolve the issue.
