Genetically modified (GM) food has raised both health-risk fears and environmental concerns. This has led some countries to ban the trade in such food triggering a great deal of controversy among countries. In this paper we ask under what conditions will voluntary labeling of GM-free food be at...

The density of fuel filling stations influences consumers' utility of private car transport. Thus, to the extent that different modes of private transport require different fuels, there may exist a network externality in the consumption of private transport. We investigate this in a formal model...

Many European politicians argue that since technological development is needed to solve the climate problem, the EU should take the lead and set tougher emission targets than what is required by the Kyoto protocol. Moreover, emission trading with other countries outside EU should be limited so...

We examine the potential of Carbon Capture and Storage (CCS) technologies in the European electricity markets, assessing whether CCS technologies will reduce carbon emissions substantially in the absence of investment subsidies, and how the availability of CCS technologies may affect electricity...

Our point of departure is that a group of developed countries invest in the development of greenhouse gas (GHG) abatement technologies both at home and in developing countries. Such investments reduce the cost of future GHG abatement, and influence the future GHG abatement choices of both...

Asymmetric regulation of a global pollutant between countries can alter the competitiveness of industries and lead to emissions leakage. For most types of pollution, abatement technologies are available for firms to produce with lower emissions. However, the suppliers of those technologies tend...

The major claim in Acemoglu, Aghion, Bursztyn & Hemous (2012) (AABH) is that subsidies for research and development of clean technologies are more important than carbon taxes when dealing with climate change. However, they - unconventionally - assume that a patent only lasts for one period. In...

Agenda 21 required countries to develop and regularly update a national set of indicators for sustainable development. Several countries now have such sets also including separate indicators for climate change. Some of these indicators typically report global concentration of green house gases...

On the one hand, wind power production is necessary for decarbonizing the electricity sector. On the other hand, we risk replacing one environmental problem with other environmental problems, that is, stopping climate change in exchange with increased loss of pristine land and biodiversity. The...
