Voters know virtually nothing about carbon dioxide removal (CDR), but warm to it quickly when exposed to more information. Voters support the Carbon Dioxide Removal Investment Act by a 68%-19% margin after reading a brief description of it. Among voters who have any familiarity with CDR (including all those who have heard at least “a little” about it), impressions of it are overwhelmingly positive (56% favorable / 16% unfavorable). And after reading a description, around two-thirds of voters (65% favorable / 15% unfavorable) – including majorities of Democrats (70% favorable), independents (66%), and Republicans (57%) – have favorable opinions of CDR.
