Its called Coming Clean - New Zealand's Emissions Trading Scheme Explained and the film maker is Lindsay Horner.
Its very good. It hammers the key points well;
- that the NZETS lacks the real cap on greenhouse gas emissions that is an essential part of a textbook 'cap-and-trade' scheme.
- that relying on post-1990 forestry carbon credits to match growth in GHGs since 1990 is the same as borrowing on a credit card, as the forestry carbon credits will have to be surrendered when the forests are eventually logged.
