Environment & Climate Change

This brief examines the national challenges related to deploying and scaling infrastructure to transport CO₂ from capture sites to storage or utilization sites at a scale consistent with achieving net-zero by 2050.

The Salata Institute for Climate and Sustainability at Harvard University launched today a major research and outreach initiative to reduce global methane emissions. The initiative seeks meaningful and sustained progress in global methane-emissions reductions through research and effective engagement with government policymakers — and with key stakeholders in business, nongovernmental organizations, and international institutions.

The geopolitical implications of solar displacing oil as the world’s major source of energy are enormous. Why has the Middle East been a central arena in the “great game” for the past century? Because countries there have been the major suppliers of the oil and gas that powered 20th-century economies. If, over the next decade, photovoltaic cells that capture energy from the sun were to replace a substantial part of the demand for oil and gas, who will the biggest losers be? And even more consequentially: who will be the biggest winner?

Renowned environmental economist Kathleen Segerson, who in addition to her academic and scholarly research and teaching has served on numerous state, national, and international advisory boards, expressed her frustration with the political polarization of climate policy in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.” The podcast is produced by the Harvard Environmental Economics Program.

An excerpt from an interview with Fran Ulmer, Senior Fellow with the Belfer Center’s Arctic Initiative, explains what we might expect from the transition to Norwegian leadership, as well as possible paths forward for the Arctic Council and Arctic governance more broadly. The interview was conducted by Belfer Center Communications and Outreach Specialist Elizabeth Hanlon. 

Visionary environmental regulator Mary Nichols, whose groundbreaking work as Chair of the California Air Resources Board (CARB) helped pave the way for many of the nation’s current environmental laws and regulations, shared her perspectives on her California and Washington D.C. experience during the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.” The podcast is produced by the Harvard Environmental Economics Program.

Joseph S. Nye argues that history shows that globalization is largely driven by technological changes that reduce the importance of distance, and that will not change.

How have Appalachia’s coal-dependent communities adjusted to historical and contemporary declines in demand for coal, and how do these shocks – and their consequences for the educational composition of affected communities – influence the capacity for future generations to adapt to new challenges? In this policy brief, Eleanor Krause presents estimates of how Appalachia’s coal country has adjusted to recent declines in coal mining employment (“coal shocks”), and demonstrates how this adjustment process is, in part, dictated by the persistent consequences of historical employment shocks in Appalachia.

Arctic Initiative Co-Director John Holdren and Senior Fellow Fran Ulmer call for increased U.S.-Canadian cooperation on geopolitical challenges around relations with Russia and China as well as the critical problems being imposed by climate change on the North American Arctic.

Steven E. Miller provides an analysis of what the Russian invasion of Ukraine means for the security dynamics of the Arctic and Northern Europe.
