The company previously spent $20 million annually in the previous two years, but believes the added investment is necessary to avert a future cocoa supply deficit.
Mars predicts that by 2020 demand for cocoa will outstrip supply by 1 million metric tons.
This week, the company published its Principles In Action summary, which details Mars’ social responsibility aims.
In 2009, the company committed to sourcing cocoa from only certified farms where audits are conducted to combat child labor and promote sustainable agricultural practices.
This July, Mars reported that it would purchase 90,000 tons of sustainable cocoa in 2012 through Rainforest Alliance, Fairtrade and UTZ Certified to meet its target to source 20% of its cocoa volume from certified farms by the end of the year.
