Mondelez International, which manufactures Cadbury and Milka, is attempting to protect its business from global warming by making the switch to sustainable cocoa.

Mondelez is currently sourcing around 43% of the cocoa for its chocolate brands through its Cocoa Life program, which provides educational and financial support to cocoa farmers in order to improve crop yield.

This week, Mondelez pledged to raise this figure to 100% by 2025, saying without a good source of quality cocoa, they can’t have a healthy chocolate business.
