The individual level consumer solutions presented in this thread are useful (and kind of common sense too), but I still wonder how can it be that ecological values are basically non-existent in mainstream skate product marketing. It sounds like a no-brainer to at least try to market with environment-friendly processes, renewable energy use etc.
skateboarding is kinda like the pinnacle of capitalism. And capitalism is a lot about generating thrash and making money out of it. The more people consume, the more they generate thrash, the more collecting and recycling companies make money. Skateboard products are already expensive. making it eco-friendly would unfortunately make skateboarding even more expensive.
Some brands plant trees when you buy shoes, others make vegan shoes (but should we use animal skins or plastics ? what's worse ?), but it's always about compromises (cost effectiveness primarily).
In the end, skateboarding is mainly for teenagers and they don't care about that. it's not a marketing leverage. Sometimes parents of these teenagers are happy to hear that boards aren't coming from China... but they don't really care as a whole.
Retail prices are the main concern
And brands want you to skate & DESTROY your own stuff and buy new stuff
