I could believe that carbon footprint was intended as a stalling tactic, but if that was the original intention, then it kind of backfired, because fossil fuel consumption must go down when citizens demand lower carbon footprint for the society.

To emit CO2, someone must be producing fossil fuels, and someone must be paying money to buy and burn it. IMO, everybody is responsible (some more than others), and if anyone starts arguing that it's the responsibility of (those different group of people), I get suspicious because that is a classical stalling tactic.
