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.
What is Solar Geoengineering?
Solar geoengineering (also known as solar radiation management or modification, SRM), refers to a set of speculative technologies to lower global temperatures by artificially intervening in the climate systems of our planet.

Solar Geoengineering Myths Debunked
Should We Block the Sun to Counter Climate Change?
As the world continues to fall short of the goals of the Paris agreement and the costs of climate change mount, is geoengineering an idea worth taking seriously, or is it a world-historically reckless distraction from the global effort to transition away from fossil fuels? Here’s a look at the debate.
