Prepaid-Strom per Smartphone
(2020)
Prepaid-Stromzähler sind in Deutschland noch selten, bieten jedoch zukünftig einen interessanten Markt. Vor allem kleinere Anbieter, aber auch erste Regionalversorger kombinieren die Megatrends Digitalisierung und Energiewende und kreieren daraus neue Dienstleistungen. Zusammen mit IT-Firmen entwickeln sie daraus neue Geschäftsideen, die auch hinsichtlich sozialer Aspekte hohen Anforderungen genügen. Der Rollout von Smart Metering-Lösungen eröffnet zukünftig noch größere Chancen, durch Echtzeit-Datenerfassung den Energieverbrauch und damit auch Einsparpotenziale transparent zu machen. Hochaufgelöste Daten ermöglichen innovative Dienstleistungen und bringen die Kundenbeziehung auf eine neue Ebene.
Driving forces of changing environmental pressures from consumption in the European food system
(2020)
The paper provides an integrated assessment of environmental and socio-economic effects arising from final consumption of food products by European households. Direct and indirect effects accumulated along the global supply chain are assessed by applying environmentally extended input-output analysis (EE-IOA). EXIOBASE 3.4 database is used as a source of detailed information on environmental pressures and world input-output transactions of intermediate and final goods and services. An original methodology to produce detailed allocation matrices to link IO data with household expenditure data is presented and applied. The results show a relative decoupling between environmental pressures and consumption over time and shows that European food consumption generates relatively less environmental pressures outside Europe (due to imports) than average European consumption. A methodological framework is defined to analyze the main driving forces by means of a structural decomposition analysis (SDA). The results of the SDA highlight that while technological developments and changes in the mix of consumed food products result in reductions in environmental pressures, this is offset by growth in consumption. The results highlight the importance of directing specific research and policy efforts towards food consumption to support the transition to a more sustainable food system in line with the objectives of the EU Farm to Fork Strategy.
Integrated assessment models (IAMs) are commonly used by decision makers in order to derive climate policies. IAMs are currently based on climate-economics interactions, whereas the role of social system has been highlighted to be of prime importance on the implementation of climate policies. Beyond existing IAMs, we argue that it is therefore urgent to increase efforts in the integration of social processes within IAMs. For achieving such a challenge, we present some promising avenues of research based on the social branches of economics. We finally present the potential implications yielded by such social IAMs.
Klimaneutralität wird im Zuge des Pariser Klimaabkommens zur politischen Zielgröße. Die Nationalstaaten, die das Abkommen unterzeichnet haben, müssen regeln, wie sie das Ziel erreichen möchten. Das deutsche Klimaschutzgesetz unterscheidet dabei zwischen "klimaneutral" und "treibhausgasneutral". Das kann zu Missverständnissen führen, kann aber auch sinnvoll sein.
