"Climate interventions with solar geoengineering could reduce climate damages if deployed in a globally coordinated regime. In the absence of such a regime, however, strategic incentives of single actors might result in detrimental outcomes. A well-known concern is that a "free-driver" (Weitzman 2015), the country with the strongest preference for cooling, might unilaterally set the global thermostat to its preferred level, thus imposing damages on others. Governance structures, i.e. more or less formal institutional arrangements between countries, could steer the decentralized geoengineering deployment towards the preferable global outcome. In this paper, we show that the coalition formation literature (an excellent summary is Ray & Vohra 2015) can make a valuable contribution to assessing the relative merit of different governance schemes."
