Since 2015 Mars has been on a journey to map our entire palm oil supply chain, publishing our full mill lists since 2018. Through the process of simplifying our supply chain, Mars will have complete traceability to the mills our palm oil is sourced from.

Mars is a member of the Roundtable on Sustainable Palm Oil (RSPO), a non-profit membership organization that promotes the growth and use of sustainable palm oil. Since 2013, we have purchased 100% of our palm oil from RSPO-certified sources through the mass balance program.

We will continue progress with simplification in line with our ambition. The full list of Tier-1 partners and significantly simplified mills supplying palm oil to Mars are available below*.
