Abstract

Geoengineering represents a set of large-scale technological interventions aimed at mitigating climate change by modifying Earth's natural systems. This report summarizes discussions from the Geoengineering Symposium held in Luleå, Sweden, in collaboration with the Swedish Foundation for Strategic Research and other key institutions. The symposium explored two primary geoengineering approaches: solar radiation management (SRM) and carbon dioxide removal (CDR). Experts assessed the feasibility, potential benefits, and risks associated with these technologies, emphasizing the uncertainties related to regional climate effects, governance challenges, and ethical concerns. Key discussions also addressed the role of international governance, public perception, and the risk of moral hazard in geoengineering deployment. The symposium concluded that while geoengineering should not replace emissions reduction efforts, it may serve as an emergency measure or complement traditional mitigation strategies. Further scientific research, climate modeling, and inclusive policymaking are crucial to evaluating the future role of geoengineering in climate action.
