"As China advances its geoengineering capabilities, the security and geopolitical risks associated with these techniques for South and Southeast Asia need to be addressed urgently—and climate diplomacy can help."

"Specifically, negative emissions technologies would directly remove greenhouse gases (GHGs) from the ambient air and help to remove accumulated atmospheric carbon dioxide (CO2) caused by historical emissions. After over a decade of debate, substantive research and planning associated with negative emissions technologies and solar radiation management have begun to inch forward. But this movement is happening in unexpected ways, and some of the most important decisions and commitments are occurring outside of the spotlight. "

"Scenarios for limiting warming below 1.5°C require both drastic emissions reductions measures and the large-scale deployment of negative emissions technologies. Both of these measures carry the potential for major unintended consequences, particularly as we do not yet understand the full implications of negative emissions technologies. Historically, the unintended consequences of climate mitigation efforts have disproportionately been borne by already marginalised communities, and hence there is a potential for the unintended consequences of measures taken to limit warming below 1.5°C to result in environmental injustice. This article argues that environmental and climate justice concerns need to be accounted for in the design of policy measures for keeping warming below 1.5°C, and outlines policy guidance for safeguarding against unintended consequences."

"This is the first book to focus on the legal aspects of these technologies: what government approvals would be needed; how liability would be assessed and compensation provided if something goes wrong; and how a governance system could be structured and agreed internationally."
