Environment & Climate Change

Harvard Kennedy School hosted Leon Clarke, Director of Decarbonization Pathways at Bezos Earth Fund, for an Energy Policy Seminar to discuss the economic challenges that are slowing the pace of the energy transition.

Plastic pollution in the Arctic marine system is sparsely quantified, and few enforceable policies are in place to ameliorate the issue. In this paper, Dewey and Mackie estimate the flux of plastic through rivers, sea ice, and ocean, and quantify marine plastic pollution from Arctic shipping and fishing. They also examine how a suite of proposed policy interventions would quantitatively change those concentrations.

Energy economist Severin Borenstein, Professor of the Graduate School at the Haas School of Business at the University of California, Berkeley, discussed the many significant challenges facing the nation’s electricity power sector in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.

Resource economist UC Berkeley Professor Meredith Fowlie spoke about the complex regulatory challenges and ‘just transition’ dynamics of climate policy in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program.” 

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.

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.

Esteemed economist Geoffrey Heal lauded recent technological advancements while also expressing his frustration with the impact of international efforts to combat climate change policy 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.

Divestment is a prominent strategy championed by activists to induce positive social change. For example, the current fossil fuel divestment movement includes over 1,500 institutions that control $40 trillion in assets. A primary pathway through which divestment is theorized to be effective is by influencing public beliefs and policy preferences, thus pressuring policymakers to take action. However, prior research only tests this argument via qualitative case studies. The authors assess the impact of exposure to information about fossil fuel divestment on public opinion through the use of national survey experiments in three major greenhouse gas emitters: the U.S., India, and South Africa.

The climate catastrophe is one of the most pressing and consequential challenges of the 21st century. To meet these challenges and maintain global leadership, the United States needs a diverse, nuanced, and data-driven approach to climate resiliency. U.S. foreign policy should prioritize climate diplomacy with an urgency that is comparable to any other U.S. national security interest.

The economist and HKS professor is passionate about solving what may be humanity's most important and perplexing problem: How to untangle fossil fuels from the global economy.
