Headline: Lay perceptions of Carbon Dioxide Utilisation technologies in the United Kingdom and Germany: An exploratory qualitative interview study

Carbon Dioxide Utilisation (CDU) technologies convert Carbon Dioxide (CO2) into carbon-based products. CDU technologies are viewed as a means of helping to address climate change while creating commodities that can be sold to generate financial revenue. While technical research and development into CDU options is accelerating, at present there has been little research into public acceptance of the technology. The current study presents the findings of a series of 28 exploratory interviews conducted with lay people in the United Kingdom and Germany. The results show that awareness of CDU is currently very low in both countries but that there is tentative support for the concept. This support is, however, caveated by considerations of the techno-economic feasibility of the technology and the societal consequences that might result from investment. While the thematic content of discussions was similar in both countries, where appropriate any notable differences are outlined and discussed. In addition to providing fresh insight into the emerging nature of public perceptions and acceptance of CDU, it is reasoned that the findings of this research could help to benefit the design of communication materials intended to engage lay-publics in debate about the nature and purpose of CDU technologies.
