Solar Geoengineering Non-Use Agreement

There are growing calls in recent years for research on “solar geoengineering“, a set of entirely speculative technologies to reduce incoming sunlight on earth in order to limit global warming. Our initiative stands against such emerging initiatives to explore planetary techno-fixes as a climate policy option. Solar geoengineering deployment at planetary scale cannot be fairly and effectively governed in the current system of international institutions. It also poses unacceptable risk if ever implemented as part of future climate policy. A strong political message from governments, the United Nations and civil society is urgently needed.
