Minority groups, Indigenousness and Indigeneity, and place in social perceptions of future climate interventions

Radical climate intervention technologies such as carbon dioxide removal and solar radiation management pose difficult questions as potential remedies for destructive climate change. The effect these technologies could have on Indigenous peoples and minority groups, and those living in rural areas, could be profound and potentially calamitous. Drawing on a large-scale, cross-country set of nationally representative surveys (n = 30,284 participants, with at least 1,000 in each country) in 30 countries and 19 languages, this article examines public preferences for climate intervention technologies through the three dimensions of minority groups, Indigenousness, and place. The survey explores 10 climate intervention or geoengineering technologies: stratospheric aerosol injection, marine cloud brightening, space-based geoengineering, afforestation and reforestation, soil carbon sequestration, blue carbon and marine biomass, direct air capture with carbon storage, bioenergy with carbon capture and storage, enhanced rock weathering, and biochar. Comparing the full sample of respondents with a subsample self-identifying as ethnic minorities or Indigenous peoples, it finds this latter category of respondents has greater familiarity with these technologies than non-members, are more positive about small-scale trials and have more positive attitudes towards engineered options (versus nature-based options). Those in cities also expressed stronger support for small-scale field trials. Moreover, members of Indigenous groups or ethnic minorities expressed significantly higher levels of support for small-scale trials for nearly all technologies, were more supportive of policy incentives, and, inter alia, less supportive of policy restrictions. Conversely, non-members of Indigenous or ethnic minority groups expressed small but significantly greater support for independent national restrictions being placed on solar radiation management and engineered forms of carbon removal.
