Realistically if you're a small company, you just do it, until someone tells you "hey you're supposed to comply with X" and then you say "oh sorry, we didn't realise, we'll do that now", repeat for all X. Programmers think the written law is a description of what actually happens - it's not.

0.8% at the size of the EU economy is a huge win. It's slightly smaller than Denmark's fossil fuel emissions. Though, the savings are presumably calculated over several years while Denmark produces it every single year.

Almost a 1% win, just by changing packaging? That seems massive.

0.8% actually sounds pretty good

I have no skin in this game, but just because they're doing it doesn't mean it's their focus, the EU is big enough to work on multiple 0.8%-size wins all over the place.
