The CHOICE Horizon Europe project, coordinated by the Institute of Communication and Computer Systems (ICCS) of the National Technical University of Athens (NTUA), successfully held its Final Event on 8–9 October 2026, at the «TEST BEFORE INVEST FACILITY» premises of ICCS/NTUA in Koropi, Greece.
Bringing together consortium partners from Europe, Africa and Latin America, the two-day event marked the culmination of three years of research, innovation and international collaboration dedicated to promoting climate-conscious choices across food production, supply chains and consumption.
The event opened with an address by Dr Angelos Amditis, ICCS Research Director and CHOICE Project Coordinator, who reflected on the project’s achievements, collaborative efforts and opportunities for the continued exploitation of its results.
The first day focused on the project’s scientific and technological achievements, including advances in Integrated Assessment Models (IAMs) that better capture human behaviour, dietary patterns and their implications for climate change, biodiversity and health.
Partners also showcased innovative digital solutions designed to translate scientific knowledge into practical action. Among them was Shrink Your Food Waste, a mobile application developed by ICCS to help consumers plan meals and monitor the environmental footprint of their food choices. Additional results included interactive climate simulation tools, educational games and 30 engaging data stories.
One of the project’s key modelling findings suggested that a global transition towards flexitarian diets could reduce annual food-system greenhouse gas emissions by approximately 35% by 2050, compared with the projected baseline, highlighting the significant potential of dietary changes for climate mitigation.
The second day was dedicated to the outcomes of five pilot demonstrations implemented in Greece, Austria, Spain, Colombia and South Africa. These pilots explored how behavioural insights, targeted communication campaigns and digital technologies can encourage more sustainable food consumption and agricultural practices.
In Greece, the pilot implemented through e-Fresh.gr combined product climate-impact information with targeted consumer engagement campaigns. During one campaign, revenue increased by 23.3% compared with the preceding period, although the evaluation also acknowledged the potential influence of external and seasonal factors.
Other pilots demonstrated promising developments in digital agriculture, sustainable coffee production, climate-resilient farming, food waste reduction and youth engagement, highlighting the importance of locally adapted approaches to climate action.
Beyond its scientific and technological achievements, CHOICE has established a valuable legacy of open-access models, digital applications, educational resources and 20 Key Exploitable Results, offering opportunities for researchers, policymakers, businesses and citizens to continue advancing sustainable food systems.
The Final Event concluded with a guided tour of the ICCS laboratory facilities, celebrating the collaboration and shared commitment of the consortium partners.
As CHOICE reaches the end of its three-year journey, its results demonstrate how combining climate science, behavioural research and digital innovation can help turn knowledge into meaningful action towards a more sustainable future.
