Environment & Climate Change

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.

For many, integrating “decarbonization” into public policy, corporate and financial strategies has become a requirement, not an option — yet, what happens when the critical link between climate stability and decarbonization breaks?

While stating that climate change is a “huge problem” in need of innovative solutions, Louisiana Congressman Garret Graves (R-6th district) made the case for bridging political divides by aligning environmental sustainability with economic sustainability during a Virtual Forum (view recording here) on Thursday (March 10). The event was hosted by the Harvard Project on Climate Agreements (HPCA) and moderated by Robert Stavins, HPCA Director and A.J. Meyer Professor of Energy and Economic Development. 

In late 2017, Mexico made headlines as Italian company Enel bid what was then a world-record low price for renewable energy in the country’s third such energy auction. This development was possible due to the historical and sweeping energy reforms passed with broad support in Mexico in 2013. Then-President Enrique Peña Nieto had succeeded where previous Mexican presidents had failed, reversing decades of resource nationalism and overhauling the energy sector through constitutional reforms that gave the private sector a larger role and advantaged renewable energy in Mexico’s economy. The 2017 auction seemed to indicate Mexico’s bright future not only as a conventional oil producer, but also as a clean energy power.

Kelly Sims Gallagher asserts that politicians' pledges of dramatic long-term reductions should not let them off the hook for their failure to achieve more modest progress in the short term.

At the Arctic Frontiers 2021 conference, Joel Clement delivered the keynote address for the "Building the future" panel. His inspirational speech was an ode to empowering youth and building a resilient Arctic — and a reflection on the discussions of the 2020 Arctic Resilience Forum.

The United States and United Kingdom have longstanding traditions in use of environmental benefit-cost analysis (E-BCA). While there are similarities between how E-BCA is utilized, there are significant differences too, many of which mirror ongoing debates and recent developments in the literature on environmental and natural resource economics. We review the use of E-BCA in both countries across three themes: (a) the role of long-term discounting; (b) the estimation and use of carbon valuation; and, (c) the estimation and use of the value of a statistical life. 

Richard Revesz, the Lawrence King Professor of Law at New York University and co-founder of the Institute for Policy Integrity, shared his thoughts on how the transition to a new presidential administration later this month will impact U.S. environmental and climate change policy in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program,” a podcast produced by the Harvard Environmental Economics Program.
