Palm oil policy Palm oil is significant as it has one of the highest yields per hectare of any oil, however, its production has been linked to significant deforestation and habitat loss, particularly across Africa and South America. In order to reduce this impact The Co-operative became the first major supermarket to commit to only using certified sustainable palm oil in its own brand products. During 2014 the Co-op was awarded 'Best Buy' status by the 'Rainforest Foundation UK' (RFUK) and Ethical Consumer magazine for its use of certified palm oil products and for its palm oil policy.
