The Need for Governance of Climate Geoengineering

  • Janos Pasztor
Abstract

Keeping global temperature rise to within 1.5–2 degrees Celsius above preindustrial levels is looking increasingly unlikely through mitigation alone. While increased adaptation to inevitable climate impacts will be necessary, a new realism is creeping into the climate debate. A growing number of scientists are proposing geoengineering technologies to deal with the expected shortfall, both through carbon dioxide removal and possibly through solar radiation management. But both approaches bring risks and pose significant governance challenges, and would likely affect different communities in different ways. As geoengineering moves mainstream, it is time to put governance at the heart of future discussion, and to broaden the debate from academia to governments, treaty bodies, faith groups, and civic organizations.

The Carnegie Climate Geoengineering Governance Initiative is a major new effort to catalyze this conversation, bringing together players from a wide range of social, geographical, and professional backgrounds. It argues that policymakers need to take an ethical risk management approach, informed by continued research. How should transborder and transgenerational ethical issues be addressed? How will governance frameworks withstand geopolitical change? Can we build on existing international treaties and institutions, or do we need new ones? And most immediately, how should further research on solar engineering be governed—given current plans to start experiments in the stratosphere? In a geoengineered world, who controls the “global thermostat”?

NOTES

1 Work has already begun on an Intergovernmental Panel on Climate Change special report on the impacts of global warming of 1.5 degrees Celcius above preindustrial levels, due for publication in 2018.

2 The home of this project is the Carnegie Council for Ethics in International Affairs. Founded in 1914 by Andrew Carnegie, the Council is an independent nonpartisan institution that works to foster global conversations on ethical issues in the international arena. Ethics & International Affairs, the journal in which this essay appears, is the Council's flagship publication.

9 Villum Kann Rasmussen was a Danish entrepreneur who created the Velux roof window. VKRF was created in 1991 to strengthen environmental research. According to its website it has funded a number of climate engineering governance projects “since there currently is no systematic, coherent set of international legal governance frameworks in place.” Further, “we need to know more about climate engineering, if only to discover what is and is not possible, and we need to be careful that investigation in this space is not driven solely by the interests of individual investors, scientists, or non-transparent governments.” See www.vkrf.org/content/what-we-fund.
