Senator BIRMINGHAM (South Australia—Minister for Education and Training) (14:37): We will, and, indeed, as my colleague Senator Sinodinos alluded to in his earlier answer, there are clear points of policy difference between the coalition and One Nation. We are committed to ensuring that Australia meets its emissions reductions targets—as Senator Brandis acknowledged earlier, our world-leading emissions reductions targets on a per capita basis. Australia has of course always done so. We have met our targets and exceeded them at every juncture. We will do so again with the 2020 targets, and we will ensure that we do so again with the 2030 targets. But we will be doing so with a firm eye as a government, as we always have, on how it is you do so while ensuring affordability and reliability. That is why our government will meet the 2020 targets without Labor's carbon tax, without that job-destroying carbon tax, which we removed, putting downward pressure on electricity prices, because we have implemented more cost-effective policies that deliver for the Australian people— The PRESIDENT: Order! Pause the clock. Senator Roberts, a point of order? Senator Roberts: Again, Mr President, I requested an answer to the question, 'Will the policies be based on hard evidence on climate science?' not as Senator Birmingham is discussing. The PRESIDENT: Thank you, Senator Roberts. The minister has five seconds in which to complete his answer. I remind the minister again of the question. Minister. Senator BIRMINGHAM: Our policies are absolutely based on evidence about climate science, affordability and reliability for Australians and their energy bills. (Time expired)
