This call aims to enhance cooperation among EU Member States and Associated Countries in the decarbonisation of energy-intensive industries, within the framework of a research and innovation (R&I) deployment agenda. It supports the implementation of the ERA Action 2025–2027 on accelerating industrial decarbonisation by fostering the exchange of best practices, aligning national and regional strategies, and promoting joint planning and monitoring. Proposals should be led by public authorities and focus on coordinating R&I funding, sharing knowledge through the INCITE platform, and aligning national efforts with EU-level initiatives such as the SET-Plan, Net Zero Industry Act, and the Clean Industrial Deal.
