Environment & Climate Change

Decarbonizing existing buildings is a key component of greenhouse gas emission reduction strategies, but private investors have been slow to finance residential decarbonization projects because of a range of barriers. Authors Chang, Fornara, and Sanghvi argue that green banks could play a major role in unlocking public and private financing for projects that are currently financially unviable. 

This brief examines the national challenges related to deploying and scaling infrastructure to transport CO₂ from capture sites to storage or utilization sites at a scale consistent with achieving net-zero by 2050.

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.

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.

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.
