Greenpeace Spain has prepared a weighted ranking of ten supermarkets based on their commitments and practices to curb the use of single-use plastic. None of the supermarkets achieves a good grade in the ranking, and Greenpeace concludes that more ambitious measures are needed to overcome the throwaway culture. Many of the supermarkets reduce the thickness of the packaging to use less plastic, or use biodegradable or compostable packaging that remains single-use, thus not effectively curbing plastic pollution.
