Mars has signed its largest-ever renewable power purchase agreements in the U.S., tapping Enel’s solar projects in Texas to accelerate supply chain decarbonization. The move reflects how food and consumer goods companies are shifting from isolated sustainability projects to system-level energy strategies.
A Contract Designed for Scale and Supply Chain Reach
The three contracts with Enel North America will generate an estimated 1.8 terawatt-hours of renewable electricity each year, avoiding roughly 700 kilotonnes of carbon emissions, according to the companies. Mars and its suppliers will draw directly on the output from Enel’s Texas solar plants, linking clean power not only to corporate operations but to upstream and downstream partners.
Enel is also introducing a dual-use model across these sites, deploying more than 6,000 sheep for vegetation control, replacing chemical herbicides and mechanical mowing. This reflects a growing trend in utility-scale solar projects, where land management practices are paired with renewable output to reduce costs and environmental impact. For Enel, the Mars contract is its largest U.S. agreement with a global corporate buyer.
Renewable Acceleration Extends Beyond Factory Walls
The partnership builds on Mars’ “Renewable Acceleration” initiative, launched earlier this year, which aims to shift all electricity needs in its supply chain onto renewable sources. Unlike traditional corporate PPAs that cover only owned facilities, Mars’ model extends to farms producing raw ingredients, the logistics networks that move finished products, and even energy tied to consumer use.
Mars estimates the program will cut 3 million tonnes of supply chain emissions by 2030 compared with 2015 levels. That target reflects only about 10% of the company’s overall footprint, underscoring how energy procurement is becoming a lever for broader value chain transformation. Recent data shows a wider shift in this direction: RE100, a coalition of major corporates committed to renewable electricity, reports that more than 70% of members now seek to extend renewable sourcing beyond direct operations into supplier networks.
Why Energy Strategy Is Becoming Competitive Ground
What’s notable about Mars’ approach is not only the size of the deal, but how it positions clean energy procurement as an operational advantage. For global manufacturers, rising regulatory scrutiny on emissions, coupled with pressure from retailers and investors, is making renewable integration a requirement for market access as much as a sustainability pledge. While many companies are still piecing together regional PPAs, Mars’ system-wide strategy may give it a head start in navigating both compliance and customer expectations.
