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

The terms ‘grandfather clause’ and ‘grandfathering’ describe elements of a policy program in which existing participants in an activity are protected from the impact of regulations, restrictions or charges applied to new entrants. In this paper, the role of grandfathering in the design...

Effective climate policy requires global emissions of greenhouse gases to be cut substantially, 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...

Uncertainty is an obstacle for commitments under cap and trade schemes for emission permits. We assess how well intensity targets, where each country's permit allocation is indexed to its future realised GDP, can cope with uncertainties in international greenhouse emissions trading. We present...

China is considering a national emissions trading scheme, to follow several pilot schemes, as part of the suite of policies to reduce the growth of greenhouse gas emissions. A carbon tax or tax-like scheme could be an alternative. However there are special challenges in a fast-growing economy...

The inaugural Australia Carbon Pricing Survey elicits expectations about the future of carbon pricing from experts working for Australia's largest greenhouse gas emitting companies, the carbon finance and investment industry and selected other experts. The survey indicates pervasive uncertainty...

This paper summarises results from the inaugural China Carbon Pricing Survey. The survey elicited expectations about the future of China's carbon price from China-based experts on carbon pricing and carbon markets during July to September 2013. The results indicate confidence that all seven of...

Uncertainty is an obstacle for commitments under cap and trade schemes. We assess how well intensity targets, where countries' permit allocations are indexed to future realised GDP, can cope with uncertainties in international greenhouse emissions trading. We present some empirical foundations...

Uncertainty can hamper the stringency of commitments under cap and trade schemes. We assess how well intensity targets, where countries' permit allocations are indexed to future realised GDP, can cope with uncertainties in a post-Kyoto international greenhouse emissions trading scheme. We...

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...
