  • When you go to the grocery store and you buy a bag of chips, a chocolate bar, crackers, ice-cream, doughnuts, frozen snacks or other candy, you may see a label on the products saying ???RSPO Certified Sustainable Palm Oil??? or ???Green Palm Sustainability.??? Such labeling makes it is easy to think that the product you are holding contains palm oil that has been produced responsibly.
