I don’t know if the spot offsets they do is in addition to that commitment or just a part of it. But their announced offsets are not the whole story.

I'm actually curious -- are they emitting more carbon than in 2012? They've replaced a lot of older, inefficient planes since then (not that that's a bad thing).
