suHCO (Systemic Sustainability Transition Solution for Health Care Organisations) is a European project funded under the Horizon Europe programme (Grant Agreement No. 101226802) and implemented through a Pre-Commercial Procurement (PCP) scheme. The project aims to support health and care organisations in their transition towards more sustainable and environmentally responsible models by fostering the development of innovative digital solutions. Through the PCP process, suHCO will procure research and development services for the creation of an AI-enabled digital platform capable of helping healthcare organisations assess their sustainability performance, identify improvement opportunities, plan and implement actions, monitor progress, and support evidence-based decision-making. The future solution is expected to integrate sustainability knowledge, regulatory requirements, standards, best practices and relevant data sources, providing users with practical guidance tailored to their organisational context. It should also support sustainable procurement processes, impact assessment, reporting activities and organisational change management. The project is driven by a Buyers Group composed of healthcare organisations from Spain, Italy and Wales. The solutions developed during the PCP will be progressively designed, prototyped and validated in real healthcare environments to ensure their relevance, usability and scalability. By bringing together healthcare providers, technology developers and sustainability experts, suHCO seeks to stimulate innovation and contribute to the sustainability objectives of European health systems.
