Description:
This working paper presents first insights on lay public perceptions of marine carbon dioxide removal (CDR) approaches. In seven focus groups, three in Germany and four in Norway (including one pilot) the researchers asked members of the lay public to share their views of the ocean and the effects of climate change, four CDR approaches, as well as their reflections on responsible research and innovation (RRI) of marine CDR. The four CDR methods were ocean iron fertilization, ocean alkalinity enhancement, artificial upwelling, and blue carbon management through restoration of coastal and marine ecosystems. In addition, respondents were asked to compare the four approaches. Our findings indicate that the public will be very supportive of blue carbon management irrespective of its actual carbon sequestration potential, due in part to the perceived bad state of marine ecosystems worldwide. Participants were skeptical whether any of the CDR approaches could have relevant effect on carbon sequestration and long-term storage; they reasoned about issues such as the ability to scale up treatments in time and space, unforeseen or unforeseeable effects on ecosystems in time and space, and the role of industry in the implementation process. They argued that despite the potential availability of marine CDR, industry and the general public should stop polluting behaviors and practices. Nevertheless, the participants universally agreed that further research on all four CDR methods should be pursued to better understand effects on climate, ecosystems, local communities, and the economy.
