Pathways for a climate-neutral and more circular bio-economy in the Vienna metropolitan region
Abstract
Vienna has recently refined its ambition to reach carbon-neutrality until the year 2040. A more circular use of resources and wastes as well as the increased utilization of biomass resources are considered essential cornerstones to achieve this goal. The resulting sustainable and circular bioeconomy is discussed as crucial development within the sustainability transformation. Nevertheless, the feasibility of the large-scale substitution of fossil fuels with biomass products in energy production as well as biomass replacing other non-renewables for construction/infrastructure and the implications for greenhouse gas (GHG) emissions and urban- hinterland relations remain unclear. PACE aims to support this sustainability transformation and decarbonization of Vienna through co-creating viable and feasible pathways towards a climate- neutral and circular bio-economy. PACE combines expert interviews, workshops with urban experts and administrators, as well as policymakers, with robust biophysical analyses, consumption-based accounting of GHG implications, and scenario modelling, addressing Vienna as embedded into a regional to global hinterland. This approach is essential to avoid that carbon savings are based on undetected carbon leakages and problem shifting beyond the administrative boundaries of the City of Vienna. Based on the evolution of the current status of circularity in biomass flows and the related GHG implications, the future option space for a circular bioeconomy which contributes to climate-neutrality until 2040 will be modelled and evaluated in a co-creation process. The transdisciplinary approach brings together biophysical data and modelling with stakeholder expertise and ensures that the pioneering biophysical assessment can identify viable options for policy-action, in particular for the Smart Klima City Wien Strategy and Sustainable Development Goals 2, 7, 11, 12, 13, and 15.
