From Mars:

Knowing where our cocoa is grown is key to delivering on our ambition of a deforestation-free cocoa supply chain by 2025. Today, for the first time, we’re publicly sharing an interactive map of each farmer group as part of our Responsible Cocoa program. 

We’re proud of our progress so far, but we’re not stopping here. Explore our map – and check back for regular updates as we advance toward our goal. [Mars.com link with map] #TomorrowStartsToday
