In order to assess climate mitigation agreements, we propose an iterative procedure linking TIAM-WORLD, a global technology-rich optimization model, and GEMINI-E3, a global general equilibrium model. The coupling methodology combines the precise representation of energy and technology choices...

Political pressure often exists for rebating environmental levies, particularly when incomplete regulatory coverage allegedly creates an“"unlevel playing field" with other, unregulated firms or industries. This paper assesses the conditions under which rebating environmental levies is justified...

L’article a pour objet d’évaluer la directive européenne sur les quotas d’émission de CO2 menée à l’aide du modèle GEMINI-E3. Après un bref rappel de la directive européenne et une description du modèle, sont décrits et analysés des scénarios correspondant à différentes...

The introduction of unilateral climate policies, and the absence of a climate constraint in many parts of the world raise questions about the distortions in competitiveness and CO2 leakage that may result. Therefore, proposed climate policies are often accompanied by corrective measures intended...

he Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) predicts global sea level to rise (SLR) by up to 60 cm by 2100 in response to ocean warming and glaciers melting. Moreover, it is expected that sea level rise might be of 1 meter or more in 2100 due to recent...

Switzerland is already and will continue to be affected by climate change. In its fourth assessment report, the IPCC indeed predicts a temperature increase of approximately 2 °C during winter and 2.5 °C during summer until 2050 compared to 1990 levels. By then, precipitation is estimated to...

In Switzerland, the research community along with public authorities are increasingly aware of the challenges raised by the necessity to adapt to future climate change. Such awareness results from the conviction that some amount of climate change will inevitably happen, even in case of important...
