On the futility of carbon trading

The New Scientist has a provocative comment piece on the shortcomings of carbon trading from Andrew Simms of the New Economics Foundation:

Unless the parameters for carbon markets are set tightly in line with what science tells us is necessary to preventing runaway warming, they cannot work. That palpably did not happen with the ETS, which initially issued more permits to pollute than there were emissions and now, in the recession, is trading emissions that don't exist - so-called hot air.
Carbon markets cannot save us unless they operate within a global carbon cap sufficient to prevent a rise of more than 2 °C above pre-industrial temperatures.
Governments are there to compensate for market failure but seem to have a blind spot about carbon markets. They could counteract the impact of low carbon prices by spending on renewable energy as part of their economic stimulus packages, yet they have not done so. The UK, for example, has spent nearly 20 per cent of its GDP to prop up the financial sector, but just 0.0083 per cent in new money on green economic stimulus.
Price mechanisms alone are unable to do the vital job of reducing carbon emissions. They are too vague, imperfect, and frequently socially unjust.

It's more than just a criticism of current trading schemes, it's pretty much a broadside against a large portion of environmental economics. I await the response, not least from these guys.
