This paper analyses the incentives to participate in an international climate agreement and the stability of the resulting climate coalition using the integrated assessment model WITCH. Coalition stability is assessed under alternative assumptions concerning the pure rate of time preference, the...

In the present paper we use the output of multiple expert elicitation surveys on the future cost of key low-carbon technologies and use it as input of three Integrated Assessment models, GCAM, MARKAL_US and WITCH. By means of a large set of simulations we aim to assess the implications of these...

Climate change is a global issue, but actions to mitigate its development are regional. Europe has taken the leadership in the carbon emission policy by introducing the Emissions Trading Scheme (EU ETS), formerly regulated by Directive 2003/87/EC and since 2013 by Directive 2009/29/EC. This new...

The importance of a focus on mobility and the kilometres travelled using light duty vehicles is reflected in the persistence of strong demand for personal mobility and emissions that tend to be linked with population and economic growth. Simulation results using the WITCH model show that changes...

With a focus on the interaction between long-term climate targets and personal transport we review the electrification of light duty vehicles (LDVs) within a model that utilizes a learning-by-researching structure. By modeling the demand of vehicles, the use of fuels and emissions implied, the...
