Commissioner Wopke Hoekstra, in a written answer on 12 June 2026, told the European Parliament that the European Commission sees no immediate need for specific EU rules on weather modification and geoengineering technologies, instead favouring international governance discussions and continued monitoring. The answer, responding to a question from MEP Anja Arndt (ESN), reaffirms the EU's precautionary approach to large-scale climate interventions, which Hoekstra said remain poorly understood in terms of risks and unintended consequences.
The Commission's position, as outlined in the answer, draws on the Joint Communication on the Climate-Security Nexus of 28 June 2023, which stressed that necessary rules and institutions have not yet been developed. Hoekstra also referenced a 2024 scientific opinion from the Group of Chief Scientific Advisors and an ethical perspective from the European Group on Ethics, both of which cautioned against deployment of solar radiation modification technologies. The Commission's Strategic Foresight Report 2025 further called for EU leadership in fostering global collaborative governance structures for such technologies.
The answer contains no concrete proposals for EU legislation, numerical targets, or deadlines. Instead, it signals a policy orientation of cautious observation and support for international efforts to assess risks and promote discussions on a potential global governance framework. The Commission is monitoring the issue but has not committed to any regulatory timeline. Institutional follow-up is likely to remain limited to continued participation in international forums and possible further scientific advice, with no immediate legislative action expected.
