Accelerating the transition of the Portuguese agri-food sector towards a more sustainable and efficient production model, aligned with the decarbonisation objectives defined at national and European levels. This sector, which is particularly relevant within the national economic structure and largely composed of SMEs, is characterised by high energy consumption—especially related to thermal processes, refrigeration, and intensive use of resources—resulting in a significant contribution to greenhouse gas emissions. The limited dissemination of low‑carbon technologies and the difficulty in assessing their technical and economic viability in real‑world contexts constitute additional barriers to the shift in the energy and production paradigm of these companies.
