In the absence of effective world-wide cooperation to curb global warming, import tariffs on embodied carbon have been proposed as a potential supplement to unilateral emissions pricing. We systematically consider alternative designs for such tariffs, and analyze their effects on global welfare...

We explore a hypothesis that a change in investment behaviour among international oil companies (IOC) towards the end of the 1990s had long-lived effects on OPEC strategies, and on oil price formation. Coordinated investment constraints were imposed on the IOCs through financial market pressures...

We analyze how different ways of allocating emission quotas may influence the electricity market. Using a large-scale numerical model of the Western European energy market with heterogeneous electricity producers, we show that different allocation mechanisms can have very different effects on...

Petroleum companies and Arctic states are carefully watching the sea ice withdrawal and the future access to petroleum resources in the Arctic. We raise the question if the global market for petroleum will actually keep the door open for substantial supply of oil and gas from the Arctic, a...

This paper analyses the impact of carbon policy on unemployment in Spain and whether recycling the public revenues earned from permit auctions can alleviate this problem. While Spain's deviation from the European Union's intermediate emission goals is more serious than most other member...

Welfare analyses of energy taxes typically show that systems with uniform rates perform better than differentiated systems, especially if revenue can be recycled by cutting taxes that are more distortionary. However, in practical policy, efficiency gains must be traded off against industrial...

The European 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 European Council has adopted mandatory differentiated national targets for each of the member states. In this paper, we consider the use of green...
