How do they choose people for these surveys? And can 24k people from 32 countries (so, 750 in each) be representative of 8 billion in 200+ countries? I know only a minority locally who could support a plastics ban, due to low awareness.
Certainly a guesstimate in other countries I can think of who are likely responsible for high plastics pollution, would be far lower than 8 or 9 out of every 10 people, as it's a contributor as to why the issue exists in those places, surely?

If they aren't, a bigger sample size won't help anyways: https://sample-size.net/confidence-interval-proportion/ https://sample-size.net/confidence-interval-proportion/

"These are the results of a survey conducted by Ipsos on its Global Advisor online platform [...] they are more urban, more educated, and/or more affluent than the general population. The survey results should be viewed as reflecting the views of the more “connected” segment of their population" So basically it's people who have internet and accepted to be paid to answer surveys. Like a Twitter poll. It's nowhere meant to be representative of the population.
