Environment & Climate Change

The international agreement on greenhouse gas emissions and climate change to be determined in Paris in December 2015 is “the greatest opportunity the world has had in 20 years to make meaningful progress on this exceptionally challenging issue,” Harvard Project on Climate Agreements (HPCA) Director Robert Stavins said in a Boston Globe op-ed in September. Stavins was in New York City during the week of the United Nations Climate Summit, which included numerous side events and a march that attracted several hundred thousand Americans calling for serious climate actions.

The Spring 2011 issue of the Belfer Center newsletter features recent and upcoming activities, research, and analysis by members of the Center community on critical global issues. This issue highlights the Belfer Center’s continuing efforts to build bridges between the United States and Russia to prevent nuclear catastrophe – an effort that began in the 1950s. This issue also features three new books by Center faculty that sharpen global debate on critical issues: God’s Century, by Monica Duffy Toft, The New Harvest by Calestous Juma, and The Future of Power, by Joseph S. Nye.

"...[T]he Copenhagen Accord is "only" a political agreement, so it does not provide sufficient assurance that countries will take action. But how much difference does it make that the Copenhagen Accord is a political rather than a legal agreement? Obviously, political agreements do not require domestic ratification, so they provide a weaker signal of domestic commitment. But the legal versus non-legal form of an instrument makes less of a difference in other respects, such as judicial enforcement, since even when an agreement is legally-binding, there are relatively few opportunities for adjudication either internationally or domestically. And evidence from other regimes suggests that states often take non-binding agreements quite seriously and make significant efforts to implement them."

This paper proposes a new architecture for international climate policy that might usefully be considered by delegates at COP 17 in Durban. It highlights a top-down approach that is designed to produce a fair distribution of burdens across countries, while achieving objectives of: (a) economic development; (b) decreasing wealth inequality; and (c) emission reductions consistent with holding the expected increase in global average temperature to 2 degrees Celsius. In addition, this discussion paper discusses several key design elements that will be important, especially from the perspective of developing countries, to the success of COP 17 and subsequent international climate negotiations. These design elements include agreements on burden sharing, choice of policy instruments, financial mechanisms and technology transfer, penalties for noncompliance, and linkages between trade and climate change.

An effective international climate agreement poses formidable challenges. Existing agreements, naturally, have some good features. Further improvements are being discussed in the current negotiations. But the cost and uncertainty associated with regular renegotiation of commitments is not being addressed. The São Paulo Proposal suggests mechanisms that would avoid the need for regular renegotiation of commitments and suggests other ways to make international climate agreements more effective.

"Implementing such a linkage is possible. The Montreal Protocol, successfully protecting the ozone layer, is already restricting trade with non-participants and non-compliers, although only in the substances controlled by the treaty. To repeat this success and overcome the obstacles for a climate agreement, signatories should become favoured trading partners while non-compliance should trigger a temporary denial of this status. Disputes can be solved by expanding the mandate of the WTO's dispute settlement body or another mediator."

A "deal" is proposed in this paper, whereby all major-emitting countries, including the United States and China, agree to reduce emissions through implementation of significant, mutually agreeable, domestic emission-reduction policies. To resolve the competitiveness and equity concerns, a proposed Carbon Mitigation Fund would be created. This proposed fund is contrasted with other existing and proposed mitigation funds and finance mechanisms. 

The finance of climate mitigation and adaptation in developing countries represents a key challenge in the negotiations on a post-2012 international climate agreement. Finance mechanisms are important because stabilizing the climate will require significant emissions reductions in both the developed and the developing worlds, and therefore large-scale investments in energy infrastructure. The current state of climate finance has been criticized for its insufficient scale, relatively low share of private-sector investment, and insufficient institutional framework. This policy brief presents options for improving and expanding climate finance.

International climate negotiations are at an impasse because the world's two largest greenhouse gas (GHG) emitters, the United States and China, are unwilling to accept binding emission-reduction commitments. At the same time, each blames the other for its inaction. This paper proposes a global "deal" for breaking the deadlock in a way that reconciles both countries' economic concerns with the imperative of reducing emissions. The deal has two core elements: (1) All major emitting countries agree to reduce GHG emissions by implementing significant, mutually agreeable, domestic policies and (2) The largest industrialized-country emitters agree to establish a global Carbon Mitigation Fund that would finance the incremental cost of adopting low-carbon technologies in developing countries.
