Open Letter - Solar Geoengineering Non-Use Agreement
www.solargeoeng.org
We call for immediate political action from governments, the United Nations, and other actors to prevent the normalization of solar geoengineering as a climate policy option.

The International Non-Use Agreement on Solar Geoengineering should commit governments to five core prohibitions and measures:

  1. The commitment to prohibit their national funding agencies from supporting the development of technologies for solar geoengineering, domestically and through international institutions.
  2. The commitment to ban outdoor experiments of solar geoengineering technologies in areas under their jurisdiction.
  3. The commitment to not grant patent rights for technologies for solar geoengineering, including supporting technologies such as for the retrofitting of airplanes for aerosol injections.
  4. The commitment to not deploy technologies for solar geoengineering if developed by third parties.
  5. The commitment to object to future institutionalization of planetary solar geoengineering as a policy option in relevant international institutions, including assessments by the Intergovernmental Panel on Climate Change.
