This paper considers the question under what conditions domestic markets of emission permits would and should merge to become an international market. Emission permits are licenses, and so governments would need to recognize other countries' permits. In a two-county model, we find that it is in...

South Africa is a water-scarce country with an average rainfall of 500 mm per year. It is estimated that national water demand will exceed supply by 2025. Increasing the water supply would be environmentally, financially or politically unfeasible. Impoverished communities, especially those in...

The current EU proposal on greenhouse gas emission reduction has 28 targets for 2020: an EU-wide one for carbon dioxide emissions covered by the European Trading System, and one target for non-ETS emission per Member State. Implementation is necessarily more expensive than needed. I consider...

Under 2013 to 2020 European Union proposals for CO2 emission reduction, a Member State can transfer to another Member State ‘part’ of their allowed emission allocation in the non-Emission Trading Sector (“ETS”). The paper addresses three questions in relation to these Transfer Emission...

This paper warns against the risk of underestimating the costs -and the uncertainty about the costs- of achieving stringent stabilization targets. We argue that a straightforward review of integrated assessment models results produces biased estimates for the more ambitious climate objectives...

Three computable general equilibrium models are used to estimate the economic implications of a stylized version of EU climate policy. If implemented at the lowest possible cost, the 20% emissions reduction would lead to a welfare loss of 0.5-2.0% by 2020. Second-best policies increase costs. A...
