The authors explore, in particular, the implications for CO2 removal and solar geoengineering of the Paris Agreement's long-term temperature goals, provision for "removals by sinks," and market-based mitigation mechanisms.

Geoengineering grows in salience, the more time that passes without an effective international regime for mitigating climate change. It will be in the background of negotiations at COP 17 in Durban—and, perhaps, in the foreground of some important discussions. This discussion paper by Daniel Bodansky explores the opportunities and risks presented by geoengineering, as well as the particular challenges to crafting an effective system of governance for this set of approaches to addressing climate change

Negotiations under the United Nations Framework Convention on Climate Change (UNFCCC) at Copenhagen in December 2009 did not produce a new international treaty with binding emissions commitments, but have defined a roadmap for dealing with global climate change in the post-2012 era. As countries continue to pursue new models for global agreement, it will be important to learn from the weaknesses of past approaches, while building on positive aspects of the experience with the Kyoto Protocol so far.

This brief considers the technology negotiations of the United Nations Framework Convention on Climate Change (UNFCCC) within the wider context of low-carbon energy technology. In doing so, it focuses on how technology issues can be effectively embedded within a potential agreement at the 15th Conference of the Parties (COP15) in Copenhagen. The paper asserts that the negotiations must be conducted with cognizance of national decision-making processes and competing priorities. It puts forth a series of framing topics in order to more explicitly explore the large technology "ecosystem". It concludes that the most appropriate area for international cooperation on technology under the UNFCCC lies in the direct provision of human and institutional capacity building with a focus on the least developed countries.

This paper considers opportunities for improved and expanded international development and transfer of climate technologies. It characterizes the economic scale of the climate technology challenge, and it reviews the pattern of public and private R&D and the rationale for R&D policies within the global innovation system. The paper clarifies the importance of options for inducing technology market demand through domestic GHG pricing, international trade, and international development assistance. It then turns to upstream innovation strategies, including international coordination and funding of climate technology R&D, and knowledge transfer through intellectual property. The paper concludes that a successful international effort to accelerate and then sustain the rate of development and transfer of GHG mitigation technologies must harness a diverse set of markets and institutions beyond those explicitly related to climate, to include those for energy, trade, development, and intellectual property.

CAMBRIDGE, Mass.— Harvard University announced a two-year project to help identify key design elements of a future international agreement on climate change, drawing upon the ideas of leading thinkers from academia, private industry, government, and advocacy organizations, both in the industrialized world and in developing countries.
