1. Introduction to CEEH Eigil Kaas, Niels Bohr Institutet Københavns Universitet

2. Interdisciplinary effort CEEH is a collaboration between seven Danish institutions working within the subject areas of Meteorology and air pollution (UoC, DMI, DMU/AU) Toxicology (AU, DMU) Epidemiology (NIPH/SDU, AU) Public health economy (CAST/SDU) Energy and system analysis (RISØ, DMU/AU, DMI) CEEH is financed by the Danish Council for Strategic Research and runs over 5 years beginning in January 2007.

3. Output A chain of different models will be used to obtain economically optimized energy systems in Denmark for a number of different “scenarios” and at different time horizons: 2010, 2020, 2030, 2040 and 2050. In CEEH their is particular focus on “externality costs” i.e. indirect environmental and health costs associated with a given setup of the Danish energy system. The final product will – for each scenario – be detailed suggestions for optimal Danish energy systems. Common language: Money and cost minimization

4. Inputs Main input: Scenarios spanning the 3-dimensional space of Technological development Economic growth Global energy prizes Additional inputs: State of the art energy technology catalogue Population and health data, local demography (including future assumptions) IPCC scenario for global/hemispheric particle emissions according to scenario A1B. Global/hemispheric/regional weather evolution in year 2000. Global “climate cost” of one kilogram of CO2 emission. IPCC scenario for physical climate changes according to scenario A1B.
