Abstract
The IPCC stated that carbon dioxide removal through negative emission technologies (NETs) is necessary to limit global warming to 1.5°C or even 2°C. Public acceptance of such technologies is an important factor that determines whether large-scale implementation and integration into society is possible. This research aimed to clarify the role of knowledge in the specific context of public acceptance of Direct Air Carbon Capture with Storage (DACCS). Previous research that investigated the effect of knowledge on acceptance of NETs found contradictory results. The impact of perceived climate severity was examined both as an independent predictor and as a moderator in the relationship between knowledge and acceptance. Specifically, this study tested whether providing more knowledge decreases acceptance of DACCS. Furthermore, it was hypothesized that perceived climate severity is positively associated with acceptance, and that the effect of knowledge is reversed for those with high perceived climate severity. A multiple regression analysis was conducted to test this model (N = 150). The results did not reveal a significant main effect of knowledge or perceived climate severity on acceptance of DACCS. Moreover, no evidence for a moderation effect of perceived climate severity was found. This indicates that other factors are more important for explaining acceptance of DACCS. Future research could investigate the relationship between perceived climate severity and perceived effectiveness, as proposed by the Protection Motivation Theory. Knowledge about DACCS does not increase acceptance of the technology, but it is still crucial for people to develop informed opinions. Information about DACCS should be contextualized to ensure that a comprehensive understanding of the technology and its implications is possible.
