This Report has been undertaken at the Bioethics Program, FLACSO Argentina in collaboration with international researchers. This three part-Report aims to provide a clear overview of the current ethical debates surrounding governance and public engagement of SRM and possible health consequences. It also attempts to sketch some answers and to provide a roadmap for the World Health Organization (WHO) to ask questions about the health-related ethics and governance of SRM. And hopes to show that—though SRM is in a preliminary stage and it is not certain it will be deployed—an anticipatory governance framework is urgently needed. And that WHO may be one among the international organisms to take the lead. Funding: WHO climate change, health, ethics initiative supported by Wellcome Grant 306679/Z/23/Z.
