The problem is that there is no such thing as a truly "Free" market, there are a lot of invisible hands tipping many scales.
Also, this sentence didn't make much sense to me:
"on a project it says will help in its efforts to trim carbon emissions by 75% compared to 2005 levels."
Why are we comparing to 2005 levels? Why not something more recent? That's extremely suspicious. Is that before we started moving a bunch of things over from coal to gas?
