Treaty Design and Duration: Effects on R&D, Participation, and Compliance

    Author:

| January 2013

Climate policy is complicated. For a treaty to be beneficial, one must think through carefully how it will work, once it is implemented. Crucial questions include the following: How should an international treaty be designed? Should one negotiate commitments for a five-year period, or for much longer? Assuming that the treaty specifies aggregate or country-specific emission caps, what should these caps be and how should they change over time? How should the agreement be updated once policymakers, scholars, and the public learn more about the severity of the climate-change problem, or about the effects of the policy? Can the treaty be designed to encourage investments in "green" abatement technology or renewable energy sources? Finally, how can one motivate countries to participate and comply with such an agreement?

| January 2010

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.

A Sectoral Approach as an Option for a Post-Kyoto Framework—Summary

The Kyoto Protocol uses a top-down mechanism to negotiate economy-wide emissions caps. This paper proposes an alternative "sectoral" approach, which would determine industry-level emissions reduction targets based on technological analyses.
