Abstract
Input-output modeling provides a means to assess socioeconomic and environmental impacts of policies and instruments and, thus, support public and private decision makers. This report discusses aspects of scenario definition and indicator set development in the context of such modeling. A first case study is concerned with green transition and regional competitiveness. We outline how scenarios may be modelled for input-output analyses on topics such as carbon taxation, energy and mobility, public procurement, and employment and skills transformation. The scenarios highlight also how national and supranational political decisions may affect local authorities. A second case study is centred on municipal solid waste management. There, we investigate how to develop an indicator set that effectively supports policymaking but is applicable within the possibilities and limitations of the underlying analysis framework.
