The documentary quite refreshingly calls out to the sad fact that instead of the creation of laws saying "you can't do it" i.e.: belch pollutants into the atmosphere, we have become a society that essentially pays corporations to not do something. It is ludicrous... and as the documentary points out, if countries were serious about curtailing carbon emissions they would tax it. The idea that you can put a bumper sticker on your hummer that says you paid a "sin" tax so you can continue driving the gas guzzler is to the point. If one really looks more deeply at the issues raised here- about how money by the financial sharks on Wall Street and also the mechanisms for trading carbon on ICE- the Intercontinental Exchange one can understand why the trading of Carbon Futures will have no positive effect on the emissions. I am all for adjusting your behavior (all 7 billion of us) or taxing!!!!
