You missed his point. People have measured this. Basically all plastic waste in the oceans come from Asia. This was true before these EU regulations and is also true of America where such bans don't exist.

It's a good example of why EU regulation sucks. It sounds like it solves a problem until you learn anything about the problem. Then it becomes clear it's all cost and no benefit.

The reason the EU passes all these rules is nothing to do with the actual problems themselves. It's because they think that by doing this they can forge a pan-European equivalent of the USA that reduces the existing nations to mere historical geographic regions. It seems to be some kind of simplistic idea that if most laws are written by the EU, and it has a flag, then it is a nation that can rival the US. If you believe that then to make it happen you have to pass a lot of laws.
