In the Middle ages social security was largely a matter for the guilds. When the guilds were abolished, insurance companies partly assumed this responsibility. Later, the Government demanded that it should take over. Now, the key question is how responsibilities can be divided between the public...

In this paper we argue that the discussion on how to get to an equitable global climate change regime requires a long-term context. Some key dimensions of this discussion are responsibility, capability and development needs. Each of these, separately or in combination, has been used in designing...

Summary Most global energy models are developed by institutes from developed countries, focusing primarily on issues that are important in industrialized countries. Evaluation of the results for Asia of the IPCC/SRES models shows that broad concepts of energy and development, the energy ladder...

We used the TIMER energy model to explore the potential role of hydrogen in the energy systems of India and Western Europe, looking at the impacts on its main incentives: climate policy, energy security and urban air pollution. We found that hydrogen will not play a major role in both regions...

Uncertainties in energy demand modelling allow for the development of different models, but also leave room for different calibrations of a single model. We apply an automated model calibration procedure to analyse calibration uncertainty of residential sector energy use modelling in the TIMER...
