Mars goes all in on renewables as emissions fall and growth climbs

Mars renewable energy and emissions reduction overview

• Mars achieves 100% renewable electricity across all US operations
• Company cut Scope 1 and 2 emissions by 42.6% since 2015
• Total value chain emissions fell 6.4% in 2025 amid growth
• RAcc programme and Enel North America contract aim to expand renewable supply
• Mars invests billions in manufacturing, sustainability funds, and regenerative agriculture

Mars, Inc has hit a major milestone – all US operations are now powered by 100% renewable electricity.

“Reaching a milestone of 100% renewable electricity in our direct US operations – from factories to offices, from veterinary hospitals to diagnostic labs – it’s something to celebrate and be proud of," says Mars CEO, Poul Weihrauch. “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. Our priority is to continue our efforts to generate good jobs, support our Associates and communities, and continuing to work towards a more resilient and sustainable future for all.”

Together with broader operational decarbonisation efforts, this contributed to a 42.6% reduction in Scope 1 and 2 GHG emissions in 2025, against a 2015 baseline. It also helped achieve a 6.4% reduction in GHG emissions across its full value chain, bringing the company’s cumulative absolute emissions reduction to 16.9% against a 2015 baseline. And all this happened while the business was growing by around 75%.

Impact across the value chain

The confectionery and snacking giant is also driving energy security through its Renewables Acceleration (RAcc) programme, a strategy aimed at extending renewable electricity beyond Mars’ direct operations and into its broader value chains. By 2030, it’s hoped this will reduce emissions by around 3 Mt (million tonnes), or roughly 10% of the company’s footprint in 2025. And new US RAcc contract with Enel North America is expected to generate approximately 1.80 TWh (trillion watt-hours) of solar electricity annually, supporting both Mars operations and its suppliers.

Added to this the American multinational now has 77 sustainability projects across 26 countries and 12 crops, including:

• Protect the Peanut: Investing approximately $5.2m (€4.4m) in crop resilience to develop drought- and disease-resistant peanut varieties and support farmers adapting to unpredictable weather events
• Raising Rice Right: Investing $20m to help scale climate-smart agriculture practices in rice production, support farmer training and resilience, and strengthen industry collaboration 
• Mars, PepsiCo, and ADM partnered to launch a regenerative agriculture programme in Poland, supporting 24 farmers in adopting more sustainable practices across more than 5,450 hectares.

“The hard work of our Associates and partners in 2025 demonstrates how sustainability sits at the centre of how we plan, invest and operate,” says Alastair Child, chief sustainability officer at Mars. “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.”

Resilience and decarbonisation

Mars has also announced significant investments across its business, strengthening its manufacturing base and supporting the decarbonisation of its value chain, while strengthening long-term resilience.

This includes plans to invest an estimated $2bn in US-based manufacturing and €1bn in its European operations by the end of 2026.

Finally, Mars has launched the Mars Sustainability Investment Fund, with a total capital commitment of up to $250m and established the Mars Impact Fund to complement its existing sustainability and philanthropic efforts.

With renewable energy deals, regenerative agriculture programmes and dedicated sustainability funds now in place, Mars is positioning itself to drive emissions reductions beyond its own operations. The challenge now will be maintaining momentum across complex global supply chains, and translating long-term commitments into measurable progress at scale.
