Mars, Incorporated has released its 2025 Sustainable in a Generation Report, detailing a 16.9 per cent cumulative reduction in absolute greenhouse gas (GHG) emissions across its full value chain against a 2015 baseline. The decarbonisation milestone was achieved despite a concurrent 75 per cent expansion in the corporation’s global business volume.
A primary driver of the group’s 2025 environmental performance was the transition of all domestic US operations—encompassing manufacturing plants, corporate offices, veterinary hospitals, and diagnostic laboratories—to 100 per cent renewable electricity. This infrastructure shift contributed to a 42.6 per cent absolute reduction in the company’s direct Scope 1 and Scope 2 emissions, alongside a 6.4 per cent annual contraction in its broader Scope 3 supply chain footprint.
To address its indirect supply chain footprint, Mars launched its Renewables Acceleration (RAcc) programme in 2025. The initiative is designed to transition upstream suppliers and agricultural partners to clean energy sources, with an operational target to eliminate approximately 3 million tonnes of $\text{CO}_2$ emissions by 2030—equivalent to roughly 10 per cent of the company’s aggregate 2025 carbon footprint.
As part of this framework, Mars finalised a commercial contract with Enel North America to back three new solar energy installations in Texas. The projects are projected to generate 1.80 terawatt-hours (TWh) of renewable electricity annually. This output will support both direct Mars infrastructure and the operations of its regional raw material suppliers through the generation of verified Renewable Energy Certificates (RECs).
The report highlighted the expansion of Mars’ sustainable sourcing network, which grew to encompass 77 active climate-smart agricultural projects across 26 countries, covering 12 distinct cash crops.
To sustain its decarbonisation trajectory, Mars announced a series of major capital expenditures targeting its global manufacturing base. The company intends to deploy an estimated $2 billion USD into US-based production facilities and €1 billion into its European Union industrial operations by the end of 2026.
Furthermore, the enterprise institutionalised its internal financing mechanisms by establishing the Mars Sustainability Investment Fund, which carries an initial capital commitment of up to $250 million USD. This vehicle operates alongside the newly formed Mars Impact Fund to accelerate technical carbon-reduction solutions throughout the corporate supply chain.
Poul Weihrauch, Chief Executive Officer of Mars, commented, “Reaching a milestone of 100% renewable electricity in our direct U.S. operations – from factories to offices, from veterinary hospitals to diagnostic labs – it’s something to celebrate and be proud of. Building a resilient business includes access to clean and accessible energy, farmers that are not at the mercy of extreme weather events and communities that thrive across our full value chain.”
Alastair Child, Chief Sustainability Officer at Mars, added, “The hard work of our Associates and partners in 2025 demonstrates how sustainability sits at the center of how we plan, invest and operate. Delivering impact at scale requires collaboration across industries, suppliers, governments, NGOs and local communities, and we remain focused on turning ambition into measurable progress across our value chain.”
