Current and proposed greenhouse gas cap-and-trade systems allow regulated entities to offset abatement requirements by paying unregulated entities to abate. These offsets from unregulated entities are believed to contain system costs and stabilize allowance prices. However, the supply of offsets...

Nearly all discussions about the appropriate consumption discount rate for climate change policy evaluation assume that a single discount rate concept applies. We argue that two distinct concepts and associated rates apply. We distinguish between a social-welfare-equivalent discount rate...

Energy generated from land-based wind power is expected to play a crucial role in the decarbonisation of the economy. With the looming biodiversity and nature crises, spatial allocation of wind power cannot, however, any longer be considered solely a trade-off against local disamenity costs....

There is a large number of regional agreements concerning Greenhouse Gas (GHG) emissions, often linked to other regional integration agreements. The most successful one in making effort in reducing carbon emissions is the Emission Trading System by the European Union (EU ETS). Apart from this...

The EU Parliament has agreed on a target of a 20 % share of renewables in the EU's total energy consumption by 2020. To achieve the target, the Council has adopted mandatory differentiated national targets for each of the Member States. In this paper we consider the potential for cost reductions...

Owing to the extensive critique of food-crop-based biofuels, attention and hopes have turned toward second-generation wood-based biofuels. An important question is therefore whether wood from boreal forests could serve as a source for biofuels. However, in a typical boreal forest, it takes...

We study interactions between a "policy bloc's" emissions quota market and an offset market where emissions offsets can be purchased from a non-policy "fringe" of countries (such as for the CDM under the Kyoto Protocol). Policy-bloc firms are assumed to benefit from free quota allocations that...

Standard economic theory provides clear guidance on the design of cost-efficient policy in the presence of imperfect markets and externalities. However, observed policies reveal extensive discrepancies between principles and practise. Based on interviews with core politicians from the Norwegian...

This paper examines the impacts of the EU Emissions Trading System (ETS) on the environmental and economic performance of Norwegian plants. The EU ETS is regarded as the cornerstone climate policy both in the EU and in Norway, but there has been considerable debate regarding its effects due to...

We theoretically and numerically analyse the impacts for a small, open country with carbon abatement ambitions of joining a coalition with allowance trading. Besides welfare impacts for both the coalition and the small, open economy joining the coalition, we scrutinise how the studied policy...
