Ferrero defended itself in a press statement released on Tuesday.
"Ferrero sources approximately 170,000 metric tons of palm oil, out of a worldwide production of 60 million metric tons, meaning that Ferrero's impact on the palm oil supply chain represents less than 0.3 percent," the company said. "All Ferrero products sold everywhere in the world, are produced with palm fruit oil that is 100 percent certified as sustainable according to the Roundtable on Sustainable Palm Oil (RSPO)."
The company has made efforts to produce palm oil sustainably. For instance, it launched a Palm Oil Charter in 2013 in order to address the causes of deforestation. The charter committed the company to sourcing palm oil responsibly, while protecting animals, the environment and the rights of workers.
