Climate policy has been a contentious issue on the Australian political scene in recent years.Former Prime Minister Julia Gillard famously promised in the 2010 election campaign that there would be no carbon tax under the government she led.Nevertheless, a carbon tax was subsequently introduced- something that was exploited by the then-opposition on their way to beating Labor at the last federal election.
Even in introducing Labor's policy for this election, opposition leader Bill Shorten has distanced himself from the carbon tax concept.
The cap on pollution is a policy that aims for a 45 percent reduction in carbon emissions by 2030, as opposed to the government's target of 26 to 28 percent by the same year.
The other pillar of the policy is an aim for 50 percent of Australia's energy to come from renewable sources by 2030.
