Charles may want to do a full post on this later, but it is worth noting that Treasury’s estimate of the cost of the ETS to taxpayers has doubled.  To quote from the Dom Post story

The Government’s plans to combat climate change will add $110 billion more than expected to New Zealand’s debt, a report out this morning has revealed.

The select committee report into National’s proposals to change the Emissions Trading Scheme says Treasury now estimated that proposals to allow much higher allocations of free carbon credits to big polluters would increase government debt by 13-17 per cent of gross domestic product by 2050.

That was about twice the 6 to 8 per cent of gdp that had previously been advised to the Cabinet.

As Phil Goff has pointed out that is like a $92,000 burden for each New Zealand family to pay for their plan.  What is more the stuff up over the cost has typified what has been a shambolic and fundamentally anti-democratic process followed by National in rushing the ETS bill through.  We will all pay for the botched process, literally.
