Climate engineering, or geoengineering, is receiving growing attention from both scientists and policymakers concerned with the slow progress of international negotiations to reduce emissions of greenhouse gases. However, scientists and climate activists seem sharply divided over the wisdom and practicality of climate engineering. The concept of climate engineering includes a wide range of different proposals for removing carbon dioxide from the atmosphere, or to reflect the sun’s light and heat back into space. These proposals differ widely with regards to technical feasibility and effectiveness, environmental risks, cost estimates, moral implications and governance challenges. However, all of the options face major challenges, not only concerning lack of understanding or inability to control the negative side-effects but also most ethical and governance issues are still unresolved. This chapter outlines and discusses governance challenges for climate engineering, and proposes some high-level principles for the governance of the field of climate engineering. Further, the chapter outlines recurrent ways in which climate engineering has been framed in public and scientific discourse and discusses how such framings may influence on the future of climate engineering. The chapter ends in a discussion about in which direction climate engineering would take future climate politics and governance.
