Description:
This deliverable synthesizes the first results on public perceptions of marine Carbon Dioxide Removal (CDR) methods from a cross-country survey in Canada, China, France, Germany, Norway, and Taiwan. The purpose is to inform the other work packages in OceanNets and stakeholders about our results in a timely and brief manner about the ways members of the public view marine CDR specifically. The survey was fielded in April 2023, has approximately 2000 observations in each country, and aims to be representative for the population active online in the respective country. It covers the marine CDR approaches ocean alkalinity enhancement (OAE), macroalgae farming with BECCS (mBECCS) or macroalgae farming with biomass sinking. Our analysis found notable differences in perceptions of the three methods and between the countries. OAE received the largest shares of negative assessments in all countries, mBECCS received the highest shares of positive assessments. Overall, respondents in the Asian countries assess ocean-based CDR approaches more positively than respondents in Western countries. We also find differences in self-reported familiarity. In Western countries, a majority (55-84%) report never having heard of these approaches; in Asian countries, a majority (56-75%) report having heard of the approaches before. Results on the associations with the methods confirm the results for the general question and add more nuanced insights into how the methods are perceived. The survey also included an experimental design that indicates a potential spillover effect, wherein presenting OAE first negatively influenced perceptions of the subsequent technology.
