French grocery retailer Carrefour is ending printed promotional leaflets in Poland, moving catalogue communication to its My Carrefour app, website and digital aggregators. Carrefour Polska said 84% of Polish consumers regularly use electronic leaflets, while paper use for promotional materials has fallen 96% since 2016. The change could eliminate up to 10,000 tonnes of paper annually. Carrefour operates more than 700 outlets in Poland. (Carrefour Polska)
