Southeast Asian expert perceptions of solar radiation management techniques and carbon dioxide removal approaches: caution, ambivalence, risk precaution, and research directions

Abstract

Abstract As the climate crisis intensifies in its impacts, discussions around the deployment of geoengineering solutions in case other interventions fail or prove insufficient have figured in research and have even been on the agenda of the United Nations. There have been calls for more investigation of geoengineering techniques to address the climate crisis. Yet, this response presents technological unknowns and economic, political, and ethical risks. Producing knowledge on these techniques has been pushed in many research institutes in the global North, especially in the United States, Europe, and Australia. Still, contributions from global South researchers, including those in Southeast Asia, remain scant. This paper describes the responses of seventeen climate and energy experts from southeast Asia on a purposively designed survey that collected expert opinions on two geoengineering techniques: solar radiation modification (SRM) and carbon dioxide removal (CDR), their risks, impacts, and governance as they pertain to their countries and region. Respondents showed ambivalence towards these techniques, with many supporting ‘natural’ CDR research and deployment while being cautious about ‘technological’ SRM and CDR research and deployment. Although respondents would welcome research on these technologies, especially their risks and impacts, they also identified critical barriers in research capacity development and funding availability.
