So far, I have posted on the comprehensiveness of the NZ ETS vs the Australian Clean Energy Future ETS, the Kyoto chart junk in the Report on the New Zealand Emissions Trading Scheme, and the over-supply of the New Zealand Units in 2010.
This post mixes two of these ideas; searching out bad charts and looking again at the supply side of the NZ ETS market, how many New Zealand Units were allocated for free to emitters and businesses.
The Report on the New Zealand Emissions Trading Scheme provides in Figure 5 a pie chart of the number of New Zealand Units (NZUs) surrendered by emitters.

America is much better in technology than governance. That’s the sentence that leapt out at me and remained prominent throughout my reading of economist Robert Repetto’s book America’s Climate Problem: The Way Forward.

The book doesn’t exactly inspire hope on either count, but it is constructive in the path it suggests for the US to follow and puts the ball squarely in the court of the policy makers.
In a rational world the notion that Canadian tar sands oil is ‘ethical’ by comparison with oil from many other sources would be laughable. But I
