Solar Geoengineering

“Solar geoengineering deployment cannot be fairly governed globally and poses unacceptable risk if implemented as a future climate policy option.¬†

We call on fellow academics, civil society organizations and concerned individuals to sign our open letter to governments, the United Nations and other actors to stop development and potential use of planetary-scale solar geoengineering technologies. 

Our initiative mobilizes especially against the most widely debated speculative technology: the massive spraying of aerosols in the stratosphere to block a part of incoming sunlight to cool the planet. Such dangerous planetary-scale interventions cannot be governed in a globally inclusive, fair and effective manner and must be banned. 

Therefore, we call for an International Non-use Agreement on Solar Geoengineering
