MICAT - Multiple Impacts Calculation Tool

Within the MICAT project, a tool to estimate Multiple Impacts of Energy Efficiency will be developed. MICAT will enable analyses at three different governance levels (local, national and EU) to address a broad target group and interested actors. This allows simplified analyses to be carried out on the basis of different data and policy scenarios in order to compare and assess the relevance of the Multiple Impacts. The project sets a sound scientific empirical basis for monitoring Multiple Impacts while providing a publicly available and easy usable online tool (MICATool) which shall be developed in a co-creational manner with the respective governance levels. The national and local cases for monitoring Multiple Impacts of Energy Efficiency will be developed further in a broad stakeholder and dissemination approach to set a standard for future reporting on Multiple Impacts of Energy Efficiency. It should open up the possibility of connecting the approach with scenario exercises and measure evaluations on EU, national and local level and thereby contributing to closing the energy efficiency gap.

There is still significant potential to improve energy efficiency in all sectors and levels where measures can be applied. Facing the often cited “energy efficiency gap”, even the profitable potential is not fully exploited. Highlighting and quantifying the additional values of energy efficiency measures and investments considering the Multiple non-energy Impacts (economic, social and environmental impacts) could help closing this gap and facilitate energy-relevant decisions and policy-making.

The main objectives of the MICAT project link science, policy and stakeholders in the field of Multiple Impacts of EE and can be formulated as follows. MICAT shall:

  • improve scientific knowledge and provide a set of methods to analyse Multiple Impacts of energy efficiency measures
  • develop a comprehensive approach and tool for estimating Multiple Impacts of EE
  • allow facilitated assessments of core policy scenarios and specific policies at EU, national and local levels estimating the outcomes of Multiple Impacts
  • establish a culture of underlining the importance and assessment of Multiple Impacts in connection with scenario approaches and policy evaluations on EU, national and local level.
