Public preferences for local carbon capture and utilization implementation: A French-German comparison

Carbon Capture and Utilization (CCU) technologies are emerging as critical solutions in addressing the climate crisis, yet their successful implementation hinges on public acceptance. This study compares public acceptance and preferences regarding local CCU implementation in Germany and France. Utilizing choice-based conjoint analysis, we examined the preferences and relevance of varying energy sources, types of hydrocarbon transport, and manufactured end-products among 2390 respondents, revealing significant differences between the two populations. Germans exhibit higher overall acceptance levels for CCU projects and attribute most importance to the energy source used – compared to French respondents, who prioritize CO₂ transport over energy source considerations. Both populations demonstrate a strong preference for minimal or no transport options, suggesting that on-site conversion facilities may alleviate community concerns. Also, a clear preference for renewable energy over nuclear power can be observed. The study highlights the importance of tailored communication strategies that address specific cultural narratives and local values to enhance public support for CCU initiatives. The insights allow for policy implications by contributing to a deeper understanding of how societal attitudes shape the future of CCU implementation across Europe.
