Postgrowth S.A.: Alimentación

Postgrowth S.A.: Alimentación was the third edition of the series, carried out during the 2025-2026 school year at IES Luís Seoane in Pontevedra. It sought to learn the food consumption pattern of the municipality's households, the social and material factors behind it and the associated greenhouse-gas emissions, in order to check whether there are differences between urban, peri-urban and rural areas. It was coordinated by the Post-Growth Innovation Lab at the Universidade de Vigo, within the Plataforma ODS project and with support from the Spanish Ministry of Social Rights, Consumer Affairs and the 2030 Agenda, between July 2025 and June 2026.

This edition introduced an important change of model. Instead of the university team going into the classrooms, it trained the school's teachers through an accredited five-session course, and the teachers themselves led the research with their students. Around 200 students from fourteen groups of lower and upper secondary and vocational training took part, together with 19 teachers. Between December 2025 and February 2026 the students went out to survey the city's households about what they buy, how much and where, and collected 587 surveys, 503 of which were valid.

Using the responses, the team estimated household food emissions with the ARCA methodology, developed by the universities of Vigo and A Coruña. Meat, fish and seafood and dairy and eggs account for more than half of the estimated emissions. The results reached the Citizens' Climate Committee and shaped three of the four challenges of the 1st Local Development Forum, held on 28 April 2026, and in July the Committee handed the City Council twelve recommendations on food and climate change. The action also left an accredited teacher-training course, with 19 teachers trained, and a reusable methodology for future editions.
