AUSTRALIA'S carbon emissions fell 8.6% in the six months since the carbon tax came into effect, government figures revealed on Thursday.
The latest corporate emissions data from the Clean Energy Regulator, for the 2011-12 year, found the 25 biggest corporate carbon-emitting companies were also responsible for 70% of all reported emissions.
While the government's carbon tax laws prevent the identification of who pays the most carbon tax, Climate Change Minister Greg Combet said the top 25 emitters were mostly from the electricity sector.
Other big companies listed as paying at least some carbon tax including many in the resources sector, some local councils and heavy industry.
A statement from Mr Combet's office said data from the National Electricity Market had confirmed carbon emissions fell 8.6% in the six months since July 1 last year, compared with the same period in 2011.
He said the fall in emissions was the equivalent of 7.6 million tonnes of carbon emissions.
