And that's exactly what all business-class carrier Silverjet is doing. They've gone completely carbon neutral -- which is basically a way of putting a dollar value against emissions, with those dollars then used for carbon cutting measures.

We don't know if this will work or spread, but, hey, we don't see how this can be a bad thing.
