    Das Kopernikus-Projekt ENavi - Die Transformation des Stromsystems mit Fokus Kohleausstieg
    (2019) Fahl, Ulrich; Gaschnig, Hannes; Hofer, Claudia; Hufendiek, Kai; Maier, Beatrix; Pahle, Michael; Pietzcker, Robert; Quitzow, Rainer; Rauner, Sebastian; Sehn, Vera; Thier, Pablo; Wiesmeth, Michael; Hufendiek, Kai; Pahle, Michael
    In diesem Bericht wird die Transformation des Stromsystems als zentrale Stellschraube zur Erreichung der Klimaziele analysiert. Dabei wird die Dekarbonisierung, insbesondere der Ausstieg aus der Kohleverstromung, in den Fokus gerückt. Anhand einer systematischen Vorgehensweise werden Transformationsszenarien für das deutsche Energiesystem identifiziert, analysiert und bewertet. Die Analyse erfolgt mithilfe unterschiedlicher computergestützter Modelle, um die Auswirkungen im gesamten System abschätzen zu können. Es werden sowohl Wechselwirkungen im Stromsystem und im Energiesystem, als auch im Wirtschaftssystem und im Bereich Ressourcen und Umwelt untersucht.

    Strategies for the effective reduction of aircraft noise exposure at airports : preparation of an integrated, effective and practice-orientated aircraft-noise reduction concept
    (Stuttgart : Institute for Energy Economics and the Rational Use of Energy (IER), 2012) Friedrich, Rainer; Müller, Wolf; Ohlau, Katrin; Bertschmann, Damaris; Maibach, Markus; Peter, Martin; Sutter, Daniel; Rokitansky, Carl-Herbert; Kubera, Barbara; Bergmann, Heidi
    Exposure of the population to aircraft noise is still a severe problem. In this study, instruments and measures are investigated with which aircraft noise exposure might be reduced to a tolerable level. These investigations are carried out exemplarily for three types of airport: an airport with a large volume of freight and night-flight operations, a medium-sized airport and a regional airport. Initially, short- and long-term objectives for noise exposure are deduced. Measures for noise reduction are then identified and their impact (noise reduction and consequential decline in health risks and annoyance) and legal feasibility assessed. The measures are subsequently consolidated in strategies (that is, packages of measures). The efficiency strategy comprises measures that are easily implemented legally; namely, an increase in takeoff and landing charges, introduction of noise-optimized approach procedures and reduction of noise limits for establishment of protection zones in accordance with the German Aircraft Noise Protection Act (Fluglärmgesetz). In the effectivity strategy further measures are implemented, in particular a night-flight ban. Long-term noise abatement objectives cannot be achieved with the short- and also long-term measures under investigation. A possible solution could be a drastic reduction in permissible noise limits for new aircraft.

    Integrated environmental health impact assessment for Europe : methods and results of the HEIMTSA/INTARESE Common Case Study
    (Stuttgart : Universität Stuttgart, IER, 2011) Friedrich, Rainer; Kuhn, Alexandra
    Within the EU FP6 projects HEIMTSA and INTARESE a framework for carrying out integrated environmental health impact assessments has been developed. In this paper, the framework is tested and applied.The following question is analysed: how do EU climate mitigation and adaptation policies and measures affect environmental health impacts in Europe? While answering this question, a number of important parameter values and functions, especially dose-response functions, concentration-response functions and exposure-impact functions as well as monetary values for health endpoints are provided, which may be used in further studies. Results show that the impact of most climate change mitigation policies on environmental human health is nearly as important as the climate change effects themselves. Quite some climate protection policies have important positive effects, i.e. they reduce health effects considerably (e.g. the use of wind or solar energy replacing oil and coal). However some policies, especially biomass burning and reducing air exchange rates in houses, cause quite high additional health impacts. The analysis also allows a ranking of stressors in environmental media with regard to overall health impacts in the EU: The highest overall damage stems from primary and secondary fine particles, followed by noise and radon. Less damage is caused by ozone, then mould followed by dioxins and heat waves. Pesticides and especially PCBs cause relatively low health impacts if only cancer endpoints are considered. This hierarchy does not change if different indicators like DALYs or monetary values are applied. Sensitivity analyses furthermore show that the pattern of importance does not change, either, if different toxicity of PM components is assumed. This information is useful to identify priorities when planning health protection policies.A general conclusion is that taking relevant ‘environmental health effects’ into account will change policy recommendations in many fields substantially.

    An approach to reducing the greenhouse gas footprint in the manufacturing industry: Determinants for an economic assessment of industrial decarbonisation measures
    (2022) Buettner, Stefan M.; Wang, Diana
    A reduction of the greenhouse gas footprint towards net zero emissions can be achieved with the help of a wide variety of measures. There are three principal approaches (categories): first, reducing greenhouse gases by adjusting the way business is done (efficiency and processes); second, substituting what business is done with (sources of energy and material); and third, offsetting the greenhouse gases emitted. Some measures seem simple and obvious, while others appear complex and demanding. The decisive factor is the respective impact on economic efficiency. Therefore, the authors have identified six types of measures that differ in terms of the impact of investment and operating costs on energy and emission costs. In this report, the authors evaluate these types of measures from an economic perspective and address the limitations and advantages and disadvantages of the different types of measures in terms of emerging needs for action and consequences. Since, for example, on-site measures are often more sensible and also the increase or introduction of emission prices in many countries can have significant cost implications (and subsequently affect global supply chains), an adjustment of the traditional approach to economic valuation seems necessary. On this basis, a novel economic valuation approach for decarbonisation measures is proposed. The approach, illustrated by calculation examples and extensions to dynamically rank, score, and adjust to changing circumstance over time, facilitates an optimal selection of measures to support companies in achieving and sustaining their greenhouse gas reduction goals while maintaining economic efficiency.
