That's a good maxim to live by, but lies come in different flavors. Are they not improving conditions at all or just not in the amount they claim they are? Are they just throwing all the recycling material they get in the dumpster or they recycle less than claimed?
I expect the latter in both cases, which put them in a better ethical standpoint than many competitors, who are just as readily patent trigger happy and actually use minor labor and recycle nothing at all.
