CSIRO denies censoring climate paper  

The ABC has a report on the efficiency of Australia's proposed ETS, which one CSIRO scientist (accurately) views as far inferior to a carbon tax - CSIRO denies censoring climate paper.

Dr Clive Spash is an ecological economist who has worked for the CSIRO since 2006, specialising in the interactions between the environment and the economy.

In Dr Spash's paper, which he has not been allowed to publish, he argues that carbon trading - like the emissions trading scheme being promoted by the Federal Government - appears to be ineffective in reducing greenhouse gas emissions.

He says more direct measures such as a carbon tax or new infrastructure would be simpler and more effective.

His paper was submitted for publication in the UK journal New Political Economy earlier this year.

But in July the CSIRO wrote to the editors, telling them the paper was being withdrawn because it had not been approved through internal CSIRO processes.
