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.

In recognition of the urgency of reducing methane emissions, several voluntary international multiparty agreements and initiatives have recently been concluded to accelerate collective action and establish formal mechanisms for monitoring the implementation of methane-related commitments. While these initiatives reflect ambition on the part of public, private, and civil society actors with regard to methane, the implementation of these initiatives presents challenges for governments, emitting sectors, and other parties.

Ely Sandler and Daniel Schrag propose a new approach to Article 6 of the Paris agreement, arguing that states must use cross-border investment to finance the energy transition. By linking additionality to an investment’s impact on cost of capital, Sandler and Schrag demonstrate how Article 6 can leverage blended finance to de-risk private investment, creating a new model of public private partnership. The paper uses case studies from the Middle East and North Africa region to demonstrate the potential economic, environmental and political benefits of cooperation on Article 6.  

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.

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. 

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.

This discussion paper explores key areas of disagreement on Article 6 and explores possible outcomes from the upcoming Conference of the Parties to the United Nations Framework Convention on Climate Change (COP-26) in November 2021 in Glasgow.

There is an urgent need to incorporate the latest science on carbon emissions from permafrost thaw and northern wildfires into international consideration of how much more aggressively societal emissions must be reduced to address the global climate crisis.

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.

How do the two major approaches to carbon pricing compare on relevant dimensions, including efficiency, cost-effectiveness, and distributional equity? This paper addresses this question by drawing on theories of policy instrument choice pertaining to the attributes — or merits — of the instruments.
