Environment & Climate Change

Following the COP27 climate conference in Egypt, Robert Stavins said in an interview with the Harvard Gazette that the talks were both frustrating and hopeful: frustrating because they did little to accelerate the slow pace of action to reduce carbon emissions, and hopeful because of a reawakened dialogue between the world’s biggest emitters—the U.S. and China—and movement to address climate-related damage to the world’s most vulnerable nations.

Robert Stavins closely examines the advantages and disadvantages of two distinct pricing instruments for reducing carbon emissions—carbon taxes and cap-and-trade. Both policy instruments are in common use today in many countries although not in the United States. Stavins looks at the practical challenges, financial implications, and political feasibility of both approaches, concluding that while they are equivalent in many ways, they can perform quite differently along other dimensions, making an apples-to-apples comparison quite difficult.

For an assessment of what was done, and left undone, at the recent United Nations’ Conference of the Parties on climate change, the Gazette spoke with Rob Stavins, the Harvard Kennedy School’s A.J. Meyer Professor of Energy and Economic Development and head of the Harvard Project on Climate Agreements, who attended his first COP in 2007 in Bali. 

Professors David Keith and Joseph Aldy and their co-authors say deeper social science research could contribute to policy decisions on this tool to address climate change.

At COP26, the focus on adaptation was more prominent than ever due to the escalating impacts of climate change, elevating adaptation to the same level as mitigation.

An analysis of the costs of climate change caused by adding one tonne of methane to the atmosphere finds that high-income regions of the world should spend much more on efforts to lower such emissions than should low-income regions.

Harvard Kennedy School professor Joseph E. Aldy discussed how policymakers can learn from past models to maximize the impact of current American energy legislation at an October 19 webinar hosted by the Harvard Project on Climate Agreements.

Professors Robert N. Stavins and David Victor explore how the coronavirus pandemic has tested the ability of many governments to respond to crises. Climate change could require a similar approach.

Former U.S. lead climate negotiator Sue Biniaz shares her thoughts on the postponement of COP26 in this interview by Professor Robert Stavins. Stavins and Biniaz explore ways to reimagine future United Nations climate negotiations, unresolved concerns from COP25, and how the United States might approach rejoining the Paris Agreement.

In a recent podcast interview, Robert Stavins and Scott Barrett discussed lessons from historic pandemics, how economists can help with policymaking surrounding the coronavirus, and what the “post-pandemic economic equilibrium” might look like. Resources Magazine has published an abridged version of their conversation.
