At Silo, wine causes a lot of headaches. Their solution is to use wind-powered transport ships. Then, they turn the waste glass into tiles. So, the carbon footprint is low.
If you can tolerate slow shipping, then the carbon footprint can be reduced. So, well-preserved food in glass (as opposed to, say, flowers in plastic) can have a lower environmental impact. Plus, glass can be reasonably reused or recycled.
