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% by 2025 and 67% by 2050 (from 2015 levels) in order to do our part to keep the planet from warming beyond two degrees. So, that’s our goal.

We took a first step by focusing on our direct operations where we have the most control and influence. As part of Mars’ legacy Sustainable in a Generation plan, we set a goal to eliminate 100% of the GHG emissions from our direct operations by 2040.  On the way to that, we set and delivered a 2015 goal of a 25% reduction.  We’re now resetting our baseline to 2015 as part of the larger Sustainable in a Generation Plan.  From this 2015 base we will still deliver a 100% reduction by 2040 and a 20% reduction by 2020 on top of our progress to date. This goal covers the energy use from about 420 sites in more than 80 countries.


Mars must do our part to keep the planet from warming beyond two degrees. This means we must reduce our total greenhouse gas emissions by 27% by 2025 and 67% by 2050.

Our Climate Action Plan

In our own operations, we’re investing in energy efficiency and renewable energy projects that allow us to tackle emissions at scale. We’re already using or purchasing renewable electricity to cover 100% of our operations in Belgium, Brazil, Lithuania, the United Kingdom and the United States.

In 2018, we’ll add Austria, the Czech Republic, France, Spain, Poland and Mexico to the list of countries where we use or fund renewable electricity to cover 100% of our operations.

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

Collaborations with 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 in some cases, sequester carbon. And, where necessary, we’re prepared to change our sourcing of key raw materials.

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.
