This submission will address the areas of the Commonwealth's Carbon Pollution Reduction Scheme Green Paper which the South Australian Government views as critically important to the impact of the scheme. One of these issues is the transition path to a low-carbon economy that is implied by the proposed design of the scheme. In this context, the submission will provide the South Australian Government's views on transitional impacts on affected households and businesses. The submission will also discuss the critical role for research and development in encouraging low emissions technologies in order to smooth the transition.
