Faced with the growing threat of climate vulnerability, many have turned to the idea of geoengineering. However, many environmentalists and human rights advocates are wary of the risks related to geoengineering. At present, there is no international agreement that governs the deployment of geoengineering technologies. This Article explores a rights-based approach for the governance of geoengineering in international law, including the impetus, rationale, and options for implementation. The approach would take into account the need for participation, accountability, nondiscrimination, and equality in its development and deployment, while addressing the potential of such technologies in mitigating the impacts that climate change would have to the full enjoyment of human rights, including the right to a healthy environment.
