Site sustainability

As one of our five core values and a cornerstone of our long-term strategy, sustainability drives us to continuously improve our ESG initiatives across our global network. As a concrete action in support our goals, the lighting system in the ointments and eye drops shopfloor in El Masnou was recently replaced with LED technology, achieving energy savings of 17.72 toe/year and avoiding 107.37 t CO₂/year. The program is co-financed by the European Regional Development Fund (ERDF), coordinated by IDAE and managed by the Catalan Institute of Energy, and funded by the National Energy Efficiency Fund, with the aim of promoting a cleaner and more sustainable economy.
