Climate change is a global problem that needs a comprehensive international response. If countries adopt different measures this may lead to carbon leakage that then leads to further emissions and to competitiveness concerns from those countries that have adopted more stringent measures. One...

For sufficiently low abatement costs many countries might undertake significant emission reductions even without any international agreement on emission reductions. We consider a situation where a coalition of countries does not cooperate on emission reductions but cooperates on the development...

In the Tragedy of the Commons Hardin suggested that with respect to global commons we are trapped in a vicious circle where calculations of utility pushes us to keep polluting our own nest. This taken on a global scale has led to concerns about climate change and a realization that measures need...

As the implications of anthropogenic climate change are better understood the pressure builds for more effective legal and policy responses at national and international levels. With climate change looming as an existential threat, climate change law ought not to be characterised merely as a...

We argue that a global carbon price is the only way to effectively tackle free riding in international climate policy, required to substantially reduce greenhouse gas emissions. We briefly review the main reasons behind the essential role of carbon pricing, address common misunderstandings and...
