Data for: Can we shop ourselves to a clean sea? An experimental panel approach to assess the persuasiveness of private labels as a private governance approach to microplastic pollution

Respondents in each country were randomly assigned to two identical panels with 500 respondents on each panel, resulting in a total of 3000 respondents. In this study, we conducted an experimental panel survey in Norway, Germany and Portugal to explore consumers willingness to pay more for products that are certified microplastic free.

This is placed within the context of private certification schemes and private governance as mechanisms to increase consumer conscientiousness, establish a higher environmental standard in terms of microplastic and reduce marine pollution. We used the polling service YouGov Omnibus. The following dataset only includes data reported on in the article.
