Think of toxin free epoxy/glue, maybe use the wood that has been grown sustainably (eg farmed or replaced after the cutting). Here is a simple brainstorm:
A fully environmentally friendly/ sustainable ski will be:
Graphic - designed by a indigenous artist hence supporting the indigenous communities
Wood (idea 1) - harvested/bought from a certified tree farm which ensures minimal/no damage to environment
Wood (idea 2) - harvested from recycled/salvaged wood, eg construction site offcuts etc.
Wood (idea 3) -
Epoxy - Ecopoxy toxin free epoxy, no VOC, no BPA, no Heavy Metals, water based (

Factory - an ISO 14001 EMS (environmental management system) certified, meaning that its constantly improving its environmental performance.
Factory - Carbon neutral offseting its ommisions by investing into the green power or green credits through tree farming/or tree sanctuaries.
That was just a short run down, if you need any more info let me know, haha got to put my recently finished Environmental Science Degree to some good use ahaha.
