During the last decade, Norway has carried out an ambitious climate policy. The main policy tool is a relatively high carbon tax, which was implemented already in 1991. Data for the development in CO2 emissions since then provide a unique opportunity to evaluate carbon taxes as a policy tool. To...

In absence of joint global climate action, several jurisdictions unilaterally restrict their domestic demand for fossil fuels. Another policy option for fossil fuel producing countries, not much explored, is to reduce own supply of fossil fuels. We explore analytically and numerically how...

Unilateral CO2 emission reduction can lead to carbon leakage, such as relocation of power-intensive and trade-exposed industries. In the EU emission trading system, these industries are also subjected to higher cost of electricity due to emission pricing in this sector. As a result, the...
