Evaluating Health Co-Benefits of Climate Change Mitigation in Urban Mobility

There is growing recognition that implementation of low-carbon policies in urban passenger transport has near-term health co-benefits through increased physical activity and improved air quality. Nevertheless, co-benefits and related cost reductions are often not taken into account in decision processes, likely because they are not easy to capture. In an interdisciplinary multi-model approach we address this gap, investigating the co-benefits resulting from increased physical activity and improved air quality due to climate mitigation policies for three urban areas. Additionally we take a (macro-)economic perspective, since that is the ultimate interest of policy-makers. Methodologically, we link a transport modelling tool, a transport emission model, an emission dispersion model, a health model and a macroeconomic Computable General Equilibrium (CGE) model to analyze three climate change mitigation scenarios. We show that higher levels of physical exercise and reduced exposure to pollutants due to mitigation measures substantially decrease morbidity and mortality. Expenditures are mainly born by the public sector but are mostly offset by the emerging co-benefits. Our macroeconomic results indicate a strong positive welfare effect, yet with slightly negative GDP and employment effects. We conclude that considering economic co-benefits of climate change mitigation policies in urban mobility can be put forward as a forceful argument for policy makers to take action

Restructuring the Austrian Energy System: An Extended Technology Wedges Approach

EU climate and energy policy defines ambitious objectives for the EU member countries requiring a fundamental change of energy systems. This paper suggests basing the analysis of restructuring options on energy services instead of energy flows. In order to provide the energy services in a sustainable way the guidelines "low energy – low carbon – low distance" should be used. This refers to an increase in energy efficiency, the reduction of fossil fuels and the reduction of (redundant) transport. An extended technology wedges approach is applied for Austria to illustrate emission reduction options through technological and behavioural changes. Two portfolios of technology wedges are quantified regarding their effects on energy flows and emissions as well as the economic impacts of investments required.climate and energy policy, energy services, technology options, input-output analysis
