This is basically a fluff piece about Lego with a side helping of climate and sustainability topics. It’s not a particularly good article in my opinion.
I think the most fundamental question facing Lego is that clone brick makers are now able to deliver excellent sets at significantly lower cost. The article doesn’t mention that at all.
Agreed. Plus I expected photos of some sort of in-house reference product archive given the title, and instead there was none of that. It's at the level of blogspam.
If they are referring to the energy cost of manufacturing it, that's got nothing to do with the raw material being fossil fuels.
