At the very end of 2012, the second part of Kyoto Protocol expired. All the countries that ratifed the protocol have guaranteed that they will cut down on their carbon emissions and curb the greenhouse gasses.
The question is: How did they do that? One of the solutions has been to buy and sell carbon credits. If e.g. a rich country in the developed world has problems in reaching the goal set in the Kyoto Protocol, they can buy Carbon Credits in the poor countries. Hocus-pocus and the arithmetic fits.
One of the major arguments for the UN, the EU and other developed countries has been to establish and support environmental friendly projects that are “additional” – meaning that the projects – supported by our part of the world – would never had been established if it had not been for the trading of carbon emissions. However, a number of the projects that the film describes was already established before the rich countries dicided to buy their credits.
