The PalmOil Scan app, developed by the World Association of Zoos and Aquariums (WAZA), rates companies based on their commitment to sustainable palm oil. Companies are evaluated on their use of certified sustainable palm oil (CSPO), conservation efforts, sourcing practices, and RSPO membership. Ratings range from Excellent to No Commitment. This company is rated "Poor" (retrieved 4 Feb 2025). However, scoring is largely dependent on reporting to the RSPO, and smaller companies may avoid membership because of the associated fees and paperwork. Therefore this criticism has not been heavily weighted.
