Mars has made a commitment to conduct business in a way that is good for the company, good for people and good for the planet.
Mars is focused on reducing carbon emissions in its own operations and is gradually increasing renewable energy supply to its sites worldwide with the goal that 100% of energy consumption will be fossil fuel free by 2040, with a stepping stone target of a 25% carbon emission reduction by 2015.
Mars has explored a number of on-site renewable generation options, either integrating them into the design stage of new sites or updating current facilities. For example, solar panels were added to the Wrigley site in Tennessee.
Utilizing renewable power generated by local resources is also an important option for some locations; electricity generated from hydropower in Brazil is used at one Mars chocolate and three Mars pet care factories.
The majority of Mars’ emissions are in its supply chain - approximately 65% - and so it is important to work with partners to generate clean power as one option to reduce carbon emissions.
A 200 MW wind farm is being built at Mesquite Creek, Texas, and is expected to go live in 2015. The wind farm will provide 800,000 MWh annually, enough electricity to supply 100% of the US energy requirements and 12% of global energy demand. Mars has signed a 20-year contract with wind farm operators Sumitomo Corporation, demonstrating its long-term commitment to renewable energy.
The Green Steam project at Hagenau chocolate factory in France meets 90% of steam demands of the site and 50% of neighbor Sonocco. The project is delivered by a partnership between Mars and GDF SUEZ – Cofely Services, which links the Schweighouse-sur-Moder Energy Recovery Unit (ERU) to the Mars Plant. The ERU generates steam from energy recovered from household waste; this steam is used to melt chocolate for M&M production.
Wrigley factories in Shanghai and Guangzhou, China; Poznan, Poland; Porici, Czech Republic; and Biesheim, France all treat wastewater anaerobically, which provides renewable energy in the form of biogas. The biogas is then used to fuel boilers and heat water. This approach prevents methane from being released into the atmosphere, in addition to reducing consumption of fossil-fuel-derived natural gas by approximately 3% annually at these sites.
In Nevada, a 4.4 acre solar garden, which generates 1.25 million kWh of energy per year, was installed in 2012. The solar garden provides 100% of the chocolate factory’s electricity needs, avoiding 867 tons of carbon emissions. When it was installed it was the largest solar installation by a food manufacturer in Nevada.
A solar garden onsite a Wrigley factory in Tennessee will generate more than 170,000 KWh annually. The site at Chattanooga has 240 solar panels installed across nearly 4,000 square feet of roof space.
Solar thermal energy is used in Guangzhou, China to warm water for showers, hand washing stations and equipment-cleaning procedures, reducing carbon emissions by nearly 200 tons per year.
Mars continues to explore renewable energy options to achieve its 2040 targets.
- Fossil fuel based energy use has reduced by 6.5% and carbon emissions fell by 5% between 2007 and 2013.
- Mars is tackling climate change to help reduce the direct impact it has on suppliers’ livelihoods and its ability to grow crops like cocoa beans for chocolate.
