Defining our Approach

Why does Mars care about climate change? Why have we committed to making our operations Sustainable in a Generation? Why do we invest in scientific research to improve agricultural crops?

The answer lies in our objective to create a mutuality of benefits by doing business in ways that are good for Mars, good for people and good for the planet. To ensure focus and effectiveness, we root our business decisions in scientific understanding. We strive to understand and quantify our impacts using accepted, publicly available data where possible, and to develop science-based strategies in response. Our targets are based on what is needed to solve the problem, rather than relying solely on what we can achieve in the immediate future.

One of the key scientific inputs we have used in this process is the concept of Planetary Boundaries1, a highly-respected analysis based on a review of existing research which identifies nine environmental impacts and the point at which each one will cause catastrophic harm to human wellbeing. We have combined this data with information about our value chain, and agricultural supply chains in particular, to identify three broad areas of impact most relevant to our business. These three areas encompass the majority of impacts in the Planetary Boundaries model. They are:

The methodologies and available data sets for calculating or estimating these impacts are at different stages of development – they are well established for greenhouse gas emissions, while there is no agreed method for assessing the impacts of land use.

We aim to help develop the methods and data sets required, and are making progress using what data is available in the meantime.

Priority Issues

Beyond environmental sustainability, we have identified broader issues that we need to address and have plotted their relevance to the success of our business against their importance to external stakeholders. Other criteria taken into account include our level of influence and the scale of the potential impacts on people and the planet. We recognize that we live in a dynamic world and the relevance of each issue may shift, so we review this matrix regularly.
