Environment & Climate Change

This paper examines the understudied role of international engagement, and of specific international actors, in greening China’s Belt-and-Road Initiative.

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?

Direct air capture (DAC) is a type of technology that captures carbon dioxide directly from the air. As the negative impacts of climate change become ever more apparent, governments and private industries have funneled increasing support toward DAC as a critical pathway toward achieving a net-zero future. Although a promising technology, wide-scale deployment of DAC faces several significant challenges.

To date, most of the climate policy attention has been focused on the need to reduce the greenhouse gases that are causing climate change and, as a corollary, to accelerate the U.S. economy’s transition from fossil fuels to clean energy. Yet climate change also is straining our nation’s emergency response capabilities as traditional climate-infused disasters such as hurricanes and floods become more frequent and destructive. At the same time, the emergency response community faces new challenges as slower-to-develop climate impacts like drought, heat, and wildfire increasingly are hitting an acute tipping points and becoming life- and livelihood-threatening disasters.

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. 

The Africa in Focus series is a forum for the intellectual and critical analysis of processes and policies from the continent and its engagement with the international community. Through thoughtful and dynamic programming, Africa in Focus brings greater African perspectives into broader policy conversations at HKS.

Arctic Initiative Faculty Affiliate Stuart Harris has been chosen as a finalist for the 2023 Frederik Paulsen Arctic Academic Action Award, recognizing scientific and academic ideas that are action-oriented and hold potential for addressing the challenges and critical needs posed by climate change in the Arctic region.

The Harvard Initiative to Reduce Global Methane Emissions released its first publication in May 2023: a research brief titled “Updating Estimates of Methane Emissions: The Case of China.” The Initiative is one of five interdisciplinary research clusters funded by the Salata Institute for Climate and Sustainability at Harvard University. The Harvard Project on Climate Agreements collaborates in the implementation of the Initiative.

Nat Keohane, a climate expert, spoke with HKS faculty member Henry Lee at a Harvard Climate Action Week event held at the Kennedy School on the challenges and opportunities for building on recent progress in U.S. climate policy.
