Denmark has been a frontrunner in policies that reduce greenhouse gas emissions and now plans to cut emissions by 70% by 2030 from 1990 levels and to achieve carbon neutrality by 2050. Such ambition induces halving emissions from 2019 levels and making the same emission abatement effort in ten...

In the European Union (EU) and in Germany the transport sector is the only sector with increasing CO2 emissions (in the EU by about 32 % and in Germany by about 1 % since 1990). Especially in road freight and air transport a further strong increase is forecasted. In the transport sector this...

I study climate policy choices for a 'policy bloc' of fuel-importers, when a 'fringe' of other fuel importers have no climate policy, fuel exporters consume no fossil fuels, and importers produce no such fuels. The policy bloc and exporter blocs act strategically in fossil fuel markets. When the...

We derive the optimal unilateral policy in a general equilibrium model of trade and climate change where one region of the world imposes a climate policy and the rest of the world does not. A climate policy in one region shifts activities - extraction, production, and consumption - in the other...

This study analyses the economic effects of the EU's ‘Fit for 55’ climate mitigation policies using the OECD ENV-Linkage model, a dynamic, global Computable General Equilibrium model. The model projects macroeconomic, sectoral, energy and emission trends for the EU, and for the five largest...

Australia has committed to achieving net zero greenhouse gas emissions by 2050 and more recently outlined a more ambitious intermediate target for emission reductions by 2030. However, achieving these targets will be challenging given a historical reliance on coal generation and the presence of...

Germany has implemented a range of measures to mitigate climate change. The implementation of such measures results in the imposition of financial burdens and restrictions on residents. Consequently, individual attitudes toward the fairness and effectiveness of such measures are a critical...

To reduce the United States’ greenhouse gas emissions by at least 80% from 1990 levels by 2050 will require multiple legal pathways for changing its transportation fuel sources. The Deep Decarbonization Pathways Project (DDPP) authors characterize the transformation required of the...

The Kyoto Protocol's success or failure should be evaluated against the unobserved counterfactual of no treatment. This requires instrumental variables. We find that countries' membership in the International Criminal Court (ICC) predicts Kyoto ratification in a panel model. Both multilateral...

We examine international cooperation on technological development as a supplement to, or an alternative to, international cooperation on emission reductions. R&D should be increased beyond the non-cooperative level if (i) the technology level in one country is positively affected by R&D in other...
