There is a large and growing literature on scientific estimates and regulatory instruments associated with international efforts to control greenhouse gas (GHG) emissions. The underlying collective action processes have received much less attention. In particular, bargaining among sovereign...

The Kyoto Protocol is not yet in force, the exact nature of domestic legal regimes governing reductions in emissions of Greenhouse Gases is (in most countries) still not known, there is no regulated scheme for transactions involving project based emission reductions and the market for such...

The effects of climate change on the world's cities and the people who live in them is not a matter that has received a great deal of attention. The effects of climate change tend to get considered in continental or regional terms – melting ice caps, agricultural crop losses across vast swaths...

The stabilisation of GHG atmospheric concentrations at levels expected to prevent dangerous climate change has become an important, global, long-term objective. It is therefore crucial to identify a cost-effective way to achieve this objective. In this paper we use WITCH, a hybrid...

In recent years, a large number of papers have explored different attempts to endogenise technical change in climate models. The obvious reason is that technical change is widely considered the main route to achieving a significant reduction in global GHG emissions. This recent literature has...

The present stalemate in climate negotiations has led policy analysts and economists to explore the possible emergence of alternative climate regimes. This paper explores the idea of replacing international cooperation on greenhouse gas emission control with international cooperation on...

It is widely recognized that technological change has the potential to reduce GHG emissions without compromising economic growth; hence, any better understanding of the process of technological innovation is likely to increase our knowledge of mitigation possibilities and costs. This paper...

Carbon budgets are a useful way to frame the climate mitigation challenge and much easier to agree upon than the allocation of emissions. We propose a mechanism with countries agreeing on the global carbon budget, while the decision to emit is decentralized at the country level. The revenue is...

This paper uses the WITCH model, a computable general equilibrium model with endogenous technological change, to explore the impact of various climate policies on energy technology choices and the costs of stabilising greenhouse gas concentrations. Current and future expected carbon prices...
