Mars released its 2025 Sustainable in a Generation Report, detailing progress against sustainability commitments while announcing that all U.S. operations now operate on 100% renewable electricity. The milestone reflects coordinated operational decarbonization aligned with broader value chain emissions reductions achieved despite growing the business by approximately 75% since the 2015 baseline.
The company achieved a 42.6% reduction in Scope 1 and 2 greenhouse gas emissions against a 2015 baseline, combined with 6.4% reduction in absolute value chain emissions in 2025 — the company’s largest single-year reduction. The cumulative progress represents 16.9% absolute emissions reduction against the 2015 baseline while expanding business operations.
“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,” said Poul Weihrauch, Mars CEO. “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.”
Renewables Acceleration program extends beyond operations
Mars is driving energy security through its Renewables Acceleration (RAcc) program, an innovative strategy launched in 2025 designed to extend renewable electricity beyond direct operations into broader value chains. By 2030, the program could reduce emissions by approximately 3 million tonnes — roughly 10% of the company’s 2025 footprint.
The latest U.S. RAcc contract with Enel North America supports three new solar projects in Texas expected to generate approximately 1.80 terawatt-hours of renewable electricity annually, serving both Mars operations and its suppliers. Wind and solar projects generate renewable energy certificates equivalent to the amount of electricity used in the company’s direct U.S. operations.
The value chain approach recognizes that Scope 3 emissions — encompassing suppliers, distribution, and customer operations — typically represent the largest emissions category for food manufacturers. Extending renewable energy access to suppliers creates coordinated decarbonization across interconnected operations.
Climate-smart agriculture expansion
Mars expanded its climate-smart agriculture portfolio to approximately 77 projects across 26 countries and 12 crops, addressing agricultural production emissions representing the largest Scope 3 component for food companies.
Protect the Peanut involves approximately $5.2 million in investments over five years toward crop resilience, developing drought- and disease-resistant peanut varieties supporting farmers adapting to unpredictable weather events. Raising Rice Right commits $20 million between 2020 and 2030 to scale climate-smart agriculture in rice production, supporting farmer training and strengthening industry collaboration.
Mars partnered with PepsiCo and ADM to launch a regenerative agriculture program in Poland, supporting 24 farmers adopting sustainable practices across more than 5,450 hectares. Mars supports regenerative wheat across 3,450 hectares for WHISKAS® and PEDIGREE® brands, improving soil health, enhancing biodiversity, and strengthening climate resilience.
Capital commitments for manufacturing decarbonization
Mars announced significant investments in 2025 to strengthen manufacturing infrastructure and supply chain decarbonization. The company plans to invest approximately $2 billion in U.S.-based manufacturing and €1 billion in European Union operations by end of 2026, enabling operational upgrades supporting emissions reduction.
The company established the Mars Sustainability Investment Fund with a total capital commitment of up to $250 million and created the Mars Impact Fund to complement existing sustainability and philanthropic efforts.
“The hard work of our Associates and partners in 2025 demonstrates how sustainability sits at the center of how we plan, invest and operate,” said Alastair Child, Mars Chief Sustainability Officer. “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.”
