The European Strategic Energy Technology Plan (SET Plan) Implementation Working Group on Sustainable and Efficient Energy Use in Industry (SET Plan IWG-Industry) enhances energy efficiency and promotes sustainable energy sourcing within the European Union's process industry. It fosters the engagement of the European energy-intensive industry community by developing synergies and facilitating the dialogue between the European Commission, the SET Plan countries and stakeholders from industry and research to identify and address the actions needed to progress on the activities outlined in the Implementation Plan. It also facilitates the alignment of European and national R&I priorities in the areas of energy-intensive industry. The SET Plan IWG-Industry is supported by the SET-IndEU project which establishes a structured Secretariat to support, monitor and reinforce its activities and results.
