Carbon Pollution Reduction Scheme
The Carbon Pollution Reduction Scheme (or CPRS) was a cap-and-trade emissions trading scheme for anthropogenic greenhouse gases proposed by the Rudd government, as part of its climate change policy, which had been due to commence in Australia in 2010. It marked a major change in the energy policy of Australia.
