Price floors in greenhouse gas emissions trading schemes can have advantages for technological innovation, price volatility, and management of cost uncertainty, but implementation has pitfalls. We argue that the best mechanism for implementing a price floor is by way of firms paying an extra fee...

There is demand for qualitative and quantitative economic analysis on the optimum degree of climate change mitigation and adaptation, the optimal timing of such actions, and their optimum distribution between countries and sectors. This paper discusses what is possible for economic modelling in...

Effective climate policy requires global emissions of greenhouse gases to be cut drastically, which in energy sectors can be achieved by lower emissions supply technologies, greater energy use efficiency, and substitution in demand. For policy to be efficient requires fairly uniform, pervasive...

Following the Copenhagen climate Accord, developed and developing countries have pledged to cut their greenhouse gas emissions, emissions intensity or emissions relative to baseline. This analysis puts the targets for the major countries on a common footing, and compares them across different...

We analyse the long-term efficiency of the emissions target and of the provisions to reduce carbon leakage in the Australian Government's Carbon Pollution Reduction Scheme, as proposed in March 2009, and the nature and likely cause of changes to these features in the previous year. The target...

Price floors in greenhouse gas emissions trading schemes can guarantee minimum abatement efforts if prices are lower than expected, and they can help manage cost uncertainty, possibly as complements to price ceilings. Provisions for price floors are found in several recent legislative proposals...

Several developing economies have announced carbon emissions targets for 2020 as part of the negotiating process for a post-Kyoto climate policy regime. China and India's commitments are framed as reductions in the emissions intensity of the economy by 40-45% and 20-25%, respectively, between...

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...

The merits of floor prices in emissions trading schemes (ETS) depend on the problem addressed. Traditional hybrid approaches emphasise automatic response to lower than anticipated abatement costs, but we find adjusting emissions targets over time is the better way to deal with this in the...
