If they have more than 50 employees, they are have probably had to make more than one moral sacrifice along the way. You will read that we do this or that, but the bottom line is well, the bottom line. Even if you try, you can't determine how much your supply chain is doing. And if you have a supply chain, well that's carbon footprint for sourcing and for distribution.

You can compare and say this one is better than that one, but morally and sustainably? Neh.
