Mars Takes Climate Action

Cutting Emissions to Fight Climate Change

Humanity’s greenhouse gas (GHG) emissions have changed the composition of our atmosphere and the climate that surrounds us. Around the world, people are beginning to feel the effects.

In order to be Sustainable in a Generation, we’ve looked at the best-available science. It tells us we must reduce the total GHG emissions across our value chain by 27 percent by 2025 and 67 percent by 2050 (from 2015 levels) in order to do our part to keep the planet from warming beyond 2 degrees. So, we are working toward that goal.

  • We took a first step by focusing on our direct operations where we have the most control and influence. We’re committed to achieve net-zero GHG emissions in our direct operations by 2040, and we are making progress by implementing renewables at scale. This goal covers Mars’ energy use from approximately 420 sites in more than 80 countries.
  • Mars is already using or purchasing renewable electricity to cover 100 percent of our operations in Austria, Belgium, the Czech Republic, France, Lithuania, Mexico, Poland, Spain, the United Kingdom and the United States. Beyond these ten countries, we have signed a new 20-year power purchase agreement with Total EREN to purchase 100% of our electricity in Australia from solar power starting in 2020.

Looking beyond our operations, we are also tackling GHG emissions in our extended supply chain. Three-quarters of our full value chain carbon footprint comes from agricultural and land use change emissions associated with the ingredients we source to make our products. We are working to transform key supply chains by working with suppliers, farmers, and other partners to prevent deforestation and produce ingredients more efficiently and effectively for a lower carbon footprint. Sustainable agricultural practices, such as efficient irrigation techniques, resistant and resilient crop varietals, and increased soil health, will not only improve environmental impacts, but can help farmers thrive.

Beyond our direct operations and deeper in our supply chains, addressing land use change and ending deforestation are among our biggest opportunities to reduce GHG emissions. Our goal is to end deforestation in our supply chains for cocoa, palm oil, paper and pulp, beef, and soy. Additionally, we’re using our purchase of these raw materials to help influence behavior across these extended supply chains.

Collaborations with suppliers and farmers, large and small, will be critical to making progress on deforestation. We’re working with them to improve agronomic practices, reduce GHG emissions, and explore opportunities to sequester carbon in soil and trees.

Using our Principles to Take Climate Action

Climate change will have significant effects on people and the planet — using The Five Principles as a guide, our goal is to be part of the solution.
