This paper identifies principles for carbon pricing that could attract a broad based and durable societal consensus in Australia. It applies these principles to a phased carbon pricing architecture as put forward by Australia’s Multi-­‐Party Committee on Climate Change, namely a government determined (fixed) carbon price transitioning to emissions trading. Linking to international carbon markets decouples Australia’s domestic carbon price from its national emissions target, allowing significant net national emissions reductions with manageable transitional impacts. A fixed price in the near term can end costly delays to carbon pricing while dealing with uncertainties about Australia’s target and international markets. A strategy is outlined to manage international uncertainties and to accommodate the multiple goals of domestic constituencies, while achieving efficiency and effectiveness. First, ensure the medium term carbon price is high enough to for emissions to begin to trend down in the next few years, recognising that investment decisions are shaped by current expectations about future prices. Second, set the initial price at a level that gives confidence that short run impacts will be manageable, given other transitional assistance. Third, ensure that wider policy settings do not compromise incentives for reducing emissions, and make the scheme robust in the face of competing claims for carbon revenue and lobbying efforts. For Australian carbon pricing policy, these principles suggest the carbon price may need to rise rapidly over the course of the decade, to double or more compared to starting prices that are currently in the Australian discussion. Payments of carbon pricing revenue to industry may need to be limited to create more room for income tax cuts, possibly by means of an overall cap and accelerated phase-­‐out of industry assistance. Forestry and agricultural offsets can be supported through the scheme, but at the cost of fiscal revenue.
