Mars has signed a renewable energy agreement with Foresight Energy Infrastructure Partners to secure the majority of output from the 277 megawatt Kölvallen Wind Farm in Sweden. The deal represents one of the company’s largest renewable energy commitments in Europe to date.

Under the agreement, Mars will purchase 70 percent of the wind farm’s annual electricity production, equating to approximately 670 gigawatt-hours of clean power each year. The commitment supported the project’s construction and financing, enabling its development at scale.

Expanding the Renewable Acceleration Program

The Swedish wind contract marks Mars’ second European agreement under its Renewable Acceleration program. Launched in 2025, the program is designed to speed the company’s transition from fossil fuels to renewable energy across both its direct operations and broader value chain.

Earlier partnerships under the program include agreements with Enel North America and GoldenPeaks Capital, the latter focused on developing more than 100 new solar projects in Poland. These deals collectively strengthen Mars’ renewable energy footprint across multiple regions.

Strengthening Scope 1, 2 and Value Chain Decarbonization

Mars set a goal in 2023 to cut carbon emissions across its entire value chain by 50 percent by 2030. Renewable electricity sourcing is a central pillar of that strategy, alongside regenerative agriculture, deforestation-free supply chains and logistics optimization.

In September 2025, the company announced that its Snacking factories in Europe reached 100 percent renewable electricity sourcing. BloombergNEF recently identified Mars as one of the top five global corporate purchasers of clean energy in 2025.

Impact on European Energy Transition

The Kölvallen Wind Farm contributes new onshore wind capacity to Sweden’s grid, supporting regional decarbonization and energy security. Large corporate power purchase agreements such as this help de-risk renewable projects and accelerate investment in clean generation infrastructure.

For Mars, the agreement reinforces its position as a major corporate clean energy buyer while embedding renewable sourcing deeper into its European operations and supply chains.
