The impact of demographic change on energy use and greenhouse gas emissions in Germany
This paper estimates the impact of demographic change on energy use and greenhouse gas emissions in Germany. Since old people display different consumption patterns than young people, an increase in the proportion of old people affects overall consumption patterns. Micro data from a household survey are used to identify age-specific consumption patterns and to project the impact of demographic change on the structure of total consumption expenditure up to the year 2030. The resulting final demand vectors are entered into an environmental input-output model, which allows the calculation of sectoral production, energy use and greenhouse gas emissions. The model results suggest that until 2030, demographic change raises the share of methane in total greenhouse gas emissions and does not contribute to reducing energy use and greenhouse gas emissions in Germany. The model is also used to explore the effects of redistributing income between age groups and a policy-induced switch from motor vehicle use to public transport.
