Senator LUDWIG (Queensland—Minister for Agriculture, Fisheries and Forestry and Minister Assisting on Queensland Floods Recovery) (14:58): I thank Senator Madigan for his question on our climate change policy. I will start by indicating that wind farms are a very cost-effective form of renewable energy and they are already cutting carbon pollution.

The Waubra wind farm was accredited under the Renewable Energy (Electricity) Act 2000 on 10 March 2009 by the Renewable Energy Regulator. Like all applications for the accreditation of a power station, it was required to submit extensive documentation and to demonstrate compliance with state or territory planning laws.

To require, as seems to be the premise of the question, the Clean Energy Regulator to enforce state and territory legislation would undermine the proper allocation of jurisdictional responsibility between state and federal governments and add unnecessary red tape to clean energy investments. A duplication of regulation and confused lines of responsibilities would in fact ensue. Clearly, there are— (Time expired)
