Wrigley uses mint to flavor 70% of its gum formulas, including some fruit-flavored products.

We are still assessing the best approach to sourcing some of the raw materials that we use in high volumes or that have high social and environmental impacts. We are committed to working with industry, governments, suppliers and other partners to ensure we source these ingredients responsibly in the long term.


We use a mix of beet and cane sugar in our chocolate and confectionery products and source most of it within the region in which it will be used, including Australia, Brazil, China, France, Germany, Mexico, the Netherlands, the UK and the US. The total volume we use is less than 1% of global supply. For several years, we have worked closely with our direct suppliers like ASR, Copersucar, Manildra and Suikerunie to ensure our sugar is responsibly sourced, while maintaining the highest levels of quality. All the sugar in our UK brand MALTESERS® is certified Fairtrade and comes from Belize.

Our sugar sourcing meets all regulatory requirements in all markets, and we assure this through the AIM-PROGRESS initiative.

We are committed to continuing to work with the industry to understand and improve the impacts of sugar cultivation, and are members of Bonsucro, the leading global stakeholder group for the sugar supply chain.


Wrigley uses mint to flavor 70% of its gum formulas, including some fruit-flavored products, so ensuring there is always high quality mint available is vital to our business. And making sure we source it responsibly is vital to all involved in our value chain.

We are identifying best practices to reduce environmental impacts of mint farming related to productivity, water usage, distillation efficiency and reduction of GHG emissions. For example, Wrigley collaborated with the Mint Industry Research Council to educate North American farmers on the environmental and economic benefits of using natural gas over diesel fuel. As of May 2014, these farmers converted 18 percent of total mint production from diesel to propane or natural gas, resulting in a reduction of over 8000 metric tonnes of carbon dioxide.

In India, another key mint growing region, Wrigley is developing a sustainable agriculture plan. This assesses our economic, environmental and social impacts, and sets strategies against these impacts to ensure we secure a vibrant Indian mint industry for the future.

Tomatoes are the key ingredient in DOLMIO® sauces and are Mars Food’s second most-used raw material after rice. We use less than 1% of the global tomato supply, and source from suppliers such as Conesa, Ingomar, Kagome and Solana.

Tomatoes are a summer crop, typically grown in warm, temperate regions using irrigation. Ensuring a secure supply of irrigation water is of prime interest. In addition, concentrating tomatoes to remove excess water from the fruits is energy-intensive.

We are developing a science-based strategy for tomato sourcing. We currently source from Australia, Chile, Italy, Portugal, Spain and the US. In many of these areas, highly efficient drip irrigation is increasingly used to improve water-use efficiency. Research suggests that improved tomato varieties and farming practices can increase yields and further reduce irrigation and water content in the fruit.

We are currently assessing alternative tomato-growing regions, using agricultural, demographic, environmental and political criteria to ensure new sources are sustainable. Once this process is complete, we will apply the water stress index developed by the Commonwealth Scientific and Industrial Research Organization to confirm the most sustainable regions from which to source tomatoes.


We need a consistent and high-quality supply of peanuts for some of our most popular products, including SNICKERS® and M&M’S® peanut candies. We are committed to working with the industry to understand and address the impacts of peanut production. This work includes:

  • Jointly funding the U.S. Peanut Resources and Efficiency Measures Report conducted by the independent research firm IHS Global Insight, which found major potential improvements in farming practices among U.S. peanut farmers

  • Leading a collaboration with industry, government and academic institutions to sequence, assemble and annotate the peanut genome

  • Chairing the American Peanut Council Sustainability Task Force

  • Supporting research to develop varieties and farming practices that reduce land, energy and water use while improving soil health

  • Developing improved logistics to reduce fuel use

  • Evaluating new roasting operations to reduce energy and water use.


Mars, Incorporated buys more corn by weight than any other raw material. Most of our confectionery products and pet food contain corn, corn-based products such as syrup, starch and sugar alcohol, or meat from animals fed on corn. We estimate that 25 percent of the raw materials we buy come directly from corn and another 26 percent are heavily dependent on it. A reliable supply of corn is therefore imperative to our future success.

However, corn is a globally produced and traded commodity with thousands of end uses both in and beyond food products, so our influence is limited. There is a substantial incentive for major users and producers to find ways to reduce the environmental impacts of growing corn. For now, we are relying on wider industry efforts regarding this crop.


Dairy ingredients are a critical component of many of our milk chocolate and caramel brands. Our suppliers include Deutsches Milchkontor GmbH, Fonterra and FrieslandCampina and in total we buy less than 1% of global dairy supplies. Since milk is produced in many places we have factories, we try to source our dairy products in origin countries close to our factories, if our quality requirements can be met – including the Netherlands, France, Germany, UK, New Zealand and the US.

We are committed to supporting a strong, high-quality dairy industry by working in partnership with others to promote more sustainable agriculture and responsible sourcing. This work includes:

  • Membership of the Dairy Working Group of the Sustainable Agriculture Initiative alongside the largest dairy users and producers in the world

  • Collaborating with other consumer brand companies and suppliers through the AIM-PROGRESS Initiative, which promotes responsible sourcing through industry collaboration

  • Membership of The Sustainability Consortium. Other members include the Innovation Center for U.S. Dairy, which has produced a lifecycle assessment of the U.S. dairy industry

  • Searching for additional regional and global groups focused on driving positive changes in the industry.
