The Governance of Solar Geoengineering
Climate change is among the world’s most important problems, and solutions based on greenhouse gas emission cuts or adapting to a new climate remain elusive. One set of proposals receiving increasing attention among scientists and policymakers is “solar geoengineering” (also known as solar radiation modification), which would reflect a small portion of incoming sunlight to reduce climate change. Evidence indicates that this could be effective, inexpensive, and technologically feasible, but it also poses environmental risks and social challenges. Governance will thus be crucial.
In this CSPO Conversation, Jesse Reynolds will draw on his just-released book, The Governance of Solar Geoengineering: Managing Climate Change in the Anthropocene (Cambridge University Press), to show how solar geoengineering is, could, and should be governed. He will focus on the most common concern: solar geoengineering could undermine already insufficient efforts to reduce greenhouse gas emissions. Can policies be crafted in which solar geoengineering could actually increase emissions cuts?
