Ilias works on maximising the positive impact of digitalisation on the green transition in cooperation with several Commission services and external stakeholders. He has initiated the European Green Digital Coalition, launched in 2021 by Commissioner Breton. Members of the Coalition have committed to work, with the support of the European Parliament Pilot project, on science-based methods to estimate the net environmental impact of digital solutions, and, to develop guidelines for deployment of such solutions in major climate critical sectors that lead to quantifiable emission reductions. Ilias also works on the Digital Product Passport as introduced in the Eco-design for Sustainable Product Regulation. The aim is to accelerate the transition to circular economy by supporting products’ sustainability and enabling sustainable business models (e.g. product as a service).
Before 2017, Ilias has contributed to the EU Agenda of eHealth and ICT for Active and Healthy Ageing for over 20 years. Areas he pioneered include digitally supported Integrated Care, 'Virtual Physiological Human' (digital twin of patient), Personal Health Systems and Electronic Health Records.
