In pursuit of a workable successor to the Kyoto Protocol, this study offers a framework of formulas that produces precise numerical targets for emissions of carbon dioxide (CO2) and other greenhouse gases, in all regions of the world in all decades of this century....Firms, consumers, and researchers base their current decisions to invest in plant and equipment, consumer durables, or new technological possibilities on the expected future price of carbon: If government commitments are not credible from the start, then they will not raise the expected future carbon price.

The climate change talks in Cancun, Mexico, didn't solve all the world's climate problems. But they were hugely successful. Through the Cancun Agreements, 194 countries reached landmark consensus (even the US and China) to set emissions targets and limit global temperature increases.

The international climate negotiations in Cancun, Mexico, have concluded, and despite the gloom-and-doom predictions that dominated the weeks and months leading up to Cancun, the Sixteenth Conference of the Parties (COP-16) of the United Nations Framework Convention on Climate Change (UNFCCC) must be judged a success.  It represents a set of modest steps forward.  Nothing more should be expected from this process.

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.

The authors compare the targets and actions to which countries have committed under the Copenhagen Accord. The Accord allows participating countries to express their commitments to reduce greenhouse-gas (GHG) emissions in a variety of ways—most broadly, through economy-wide quantified emissions targets for developed countries and mitigation "actions" by developing countries. These are difficult to compare. However, even mitigation commitments that look similar can require very different levels of effort in different countries, and commitments that produce similar economic outcomes can look inequitable. These variations in effort and equity depend on historical patterns of energy use, marginal costs of greenhouse-gas abatement, choice of base year, methods for determining "business as usual" projections, and other factors.

There is no integrated, comprehensive regime governing efforts to limit the extent of climate change. Instead, there is a regime complex: a loosely coupled set of specific regimes. We describe the regime complex for climate change and seek to explain it, using functional, strategic, and organizational arguments. It is likely that such a regime complex will persist: efforts to build an effective, legitimate, and adaptable comprehensive regime are unlikely to succeed. Building on this analysis, we argue that a climate change regime complex, if it meets specified criteria, has advantages over any politically feasible comprehensive regime, particularly with respect to adaptability and flexibility. These characteristics are particularly important in an environment of high uncertainty, such as in the case of climate change where the most demanding international commitments are interdependent yet governments vary widely in their interest and ability to implement such commitments.

Sectoral approaches have been gaining currency in the international climate debate as a possible remedy to the shortfalls of the Kyoto Protocol. Proponents argue that a sector-based architecture can more easily invite the participation of developing countries, address competitiveness issues, and enable immediate emissions reductions. However, given the numerous proposals, much confusion remains as to what sectoral approaches actually are. This article provides a simple, yet comprehensive, taxonomy of the various proposals for sectoral approaches.

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.
