What interests me is that the things I've noticed are not necessarily things included in new legislation.

It suggests to me that the intervention is prompting businesses to consider their all round plastic use (i.e. they're making proactive change expecting upcoming legislation) or they're responding to consumer opinion.

Either way, this is a really positive step. Also, more importantly, the public seem supportive. I think the success of the 5p plastic bag charge has made people rethink their opposition to green schemes.
