Dunkin’ Brands Group has agreed to set a target date to source 100 percent of the palm oil it uses from sustainable sources, according to an article from Forbes.com.

Dunkin’ currently produces all of its donut products with a blend of soy, palm and cottonseed oil—a blend it created in 2007 to satisfy trans fat-free requirements. The chain has come under attack in the past by environmental groups claiming the cost of palm oil production from unsustainable sources causes devastating environmental and climate damage.

“Consumers may not realize that many of the foods and cosmetics they eat and use contain palm oil that has been harvested in ways that are severely detrimental to the environment,” DiNapoli said in a statement. “Shareholder value is enhanced when companies take steps to address the risks associated with environmental practices that promote climate change.”
