Policy brief
Enhancing EU legal frameworks for Solar Radiation Modification

Policy brief | 28 February 2023

In short

Solar Radiation Modification (SRM) refers to a type of climate engineering technique that aims to reflect sunlight and heat back into space to reduce warming.

This policy brief sets out recommendations based on the regulatory challenges related to SRM that were identified in our analysis of EU laws and policies. We address them to EU policymakers and officials involved in the preparation of legislative or policy initiatives related to climate action, climate technologies, climate engineering, geoengineering, and SRM specifically.

To protect and uphold ethical, fundamental rights and sustainability considerations in the research and development of SRM, TechEthos encourages policy makers to:

  • Clarify the definition and various types of research activities that constitute SRM research;
  • Determine the conditions under which – if any – research into various types of SRM may be conducted;
  • Clarify the role – if any – of various types of SRM in alleviating the impacts of climate change;
  • Evaluate the effects of SRM research activities on EU fundamental rights and principles;
  • Collaborate internationally and evaluate existing international governance regimes
