Mars Powers All U.S. Operations With 100% Renewable Electricity

Mars now powers all U.S. operations with 100% renewable electricity, covering factories, offices, veterinary hospitals and diagnostic labs.
The company cut Scope 1 and Scope 2 greenhouse gas emissions by 42.6% against a 2015 baseline, meeting its science-based target.
Mars reduced full value chain emissions by 6.4% in 2025, its largest annual cut to date, while growing the business by about 75% since 2015.

Mars Reaches U.S. Renewable Electricity Goal

Mars has moved all of its U.S. operations to 100% renewable electricity, a major step in the company’s global decarbonization strategy.

The achievement covers a wide operational base. It includes factories, corporate offices, veterinary hospitals and diagnostic labs. The update was released with the company’s 2025 Sustainable in a Generation Report, which tracks progress across climate, agriculture, manufacturing and value chain resilience.

Mars said the shift helped cut Scope 1 and Scope 2 greenhouse gas emissions by 42.6% from a 2015 baseline. That reduction meets the company’s science-based target for direct operations and purchased energy.

The company also reported a 6.4% drop in absolute greenhouse gas emissions across its full value chain in 2025. That is its largest annual reduction to date. It brings Mars’ cumulative absolute emissions reduction to 16.9% against 2015 levels, despite business growth of about 75% over the same period.

Poul Weihrauch, Mars CEO, said: “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. 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.”

Renewable Power Moves Into the Supply Chain

Mars is now extending its clean energy strategy beyond direct operations. Its Renewables Acceleration, or RAcc, program launched in 2025 to expand renewable electricity across the company’s wider value chain.

By 2030, Mars estimates the program could reduce emissions by around 3 million metric tons. That equals roughly 10% of the company’s 2025 footprint.

The latest U.S. RAcc contract is with Enel North America. It will support three new solar projects in Texas. The projects are expected to generate about 1.80 terawatt-hours of renewable electricity each year.

The electricity will support both Mars operations and its suppliers. For large consumer goods groups, this is where climate execution becomes more complex. Scope 3 emissions often sit outside direct control, yet they dominate the footprint of global food and pet care businesses.

Mars also uses wind and solar projects that generate Renewable Energy Certificates equivalent to the electricity used by its direct U.S. operations. The company said it continues to invest in reducing and converting energy consumption across its footprint.

Agriculture Becomes a Climate Risk Priority

Mars also expanded its climate-smart agriculture work in 2025. The company now has about 77 projects across 26 countries and 12 crops.

The programs target supply resilience in crops that face rising climate pressure. They also show how food companies are moving beyond factory emissions. For investors and procurement leaders, agriculture is now a core climate risk category.

Mars invested about $5.2 million over five years in its Protect the Peanut program. The initiative focuses on drought- and disease-resistant peanut varieties. It also supports farmers dealing with more unpredictable weather.

The company is also investing $20 million between 2020 and 2030 through its Raising Rice Right program. The initiative aims to scale climate-smart rice production, support farmer training and strengthen industry collaboration.

In Poland, Mars partnered with PepsiCo and ADM on a regenerative agriculture program. The project supports 24 farmers across more than 5,450 hectares. Mars is backing regenerative wheat across 3,450 hectares for brands including WHISKAS® and PEDIGREE®. The program aims to improve soil health, support biodiversity and build long-term climate resilience.

Alastair Child, Mars Chief Sustainability Officer, said: “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.”

Capital Spending Links Growth and Decarbonization

Mars paired its climate progress with major capital commitments. The company announced plans to invest an estimated $2 billion in U.S. manufacturing and €1 billion in European Union operations by the end of 2026.

The investments are designed to strengthen manufacturing capacity while supporting value chain decarbonization and business resilience. For executives, this matters because sustainability spending is increasingly tied to energy security, supply assurance and long-term operating risk.

Mars also launched the Mars Sustainability Investment Fund, with total capital commitments of up to $250 million. It established the Mars Impact Fund to complement its existing sustainability and philanthropic programs.

The company’s latest report places Mars in a broader corporate shift. Global businesses are under growing pressure to show absolute emissions cuts, not only intensity gains. They also face investor scrutiny over Scope 3 delivery, renewable procurement quality and climate adaptation across supply chains.

For Mars, the U.S. renewable electricity milestone is a clear operational win. The harder test now sits across suppliers, farms and manufacturing expansion. Its 2025 results show progress, but also point to the next phase of corporate climate execution: turning renewable procurement, capital spending and agricultural resilience into measurable global emissions reductions.
