IN Brief:
- Mars says its US direct operations are now powered by 100% renewable electricity.
- The company has cut Scope 1 and 2 emissions by 42.6% since 2015 and reduced full value-chain emissions in 2025.
- Manufacturing investment, supplier agriculture programmes, and renewable procurement are becoming connected parts of food industry resilience planning.
Mars has reached 100% renewable electricity across its direct US operations, adding another milestone to its wider programme to cut emissions across manufacturing, agriculture, and the food supply chain.
The company has also reported a 42.6% reduction in Scope 1 and 2 greenhouse gas emissions against its 2015 baseline, alongside a reduction in full value-chain emissions in 2025. Mars has linked those results to renewable electricity procurement, operational decarbonisation, manufacturing investment, and work across agricultural supply chains.
The renewable milestone covers direct US operations, from factories and offices through to veterinary hospitals and diagnostic labs. Mars is also using its Renewables Acceleration programme to extend renewable electricity work beyond direct operations and into its value chain, including a US contract with Enel North America intended to generate approximately 1.80TWh of solar electricity each year.
Electricity procurement is now moving directly into industrial strategy. Large food plants depend on reliable, cost-visible power for refrigeration, drying, cooking, pumping, compressed air, packaging, warehousing, and material handling. A renewable electricity agreement can therefore support long-term planning in a market where energy volatility has repeatedly exposed manufacturing margins.
Mars is connecting power sourcing with agriculture, where it has identified projects across multiple crops and countries, including work on peanut resilience, rice production, and regenerative agriculture. These programmes sit outside factory walls, but they influence ingredient availability, cost exposure, and long-term supply quality. A business built across confectionery, snacks, petcare, and food brands has to manage agricultural risk and manufacturing risk together.
The company has already been applying the same logic in Europe, where a long-term wind power agreement is linked to its Lithuanian pet food manufacturing site. The Gargždai site power agreement tied renewable capacity to a defined production footprint, showing how energy strategy is becoming part of site planning, supplier engagement, and investment discipline.
The emissions figures stand out because many food manufacturers have struggled to reduce carbon while continuing to grow. Direct emissions reductions can be achieved through renewable electricity, energy efficiency, electrification, and site-level improvements. Full value-chain emissions are harder, because they include agricultural inputs, logistics, third-party manufacturing, packaging, retail, and product use.
Mars has also indicated substantial manufacturing investment in the US and Europe. Newer production assets can be designed with better energy performance, more efficient utilities, improved heat recovery, cleaner power integration, and stronger digital monitoring. Retrofitting older plants is generally harder, although food companies cannot wait for full estate renewal before reducing emissions.
Retail customers increasingly ask for emissions data, credible renewable sourcing, and evidence of progress against climate commitments. Regulators are moving towards more demanding corporate sustainability disclosure. Investors and lenders are watching transition risk more closely. At plant level, high energy costs still affect product cost, pricing decisions, and capital allocation.
Confectionery and snacks add another layer of exposure because several core ingredients face climate pressure. Cocoa, peanuts, rice, dairy, palm-related inputs, and sugar all carry supply risks shaped by weather, disease, farm economics, and land-use scrutiny. Renewable electricity helps cut direct operational emissions, but a resilient food business also needs agricultural programmes that protect supply volume and quality.
The Mars update shows how the boundary between sustainability and operations is narrowing. Renewable power is relevant because factories need energy. Regenerative agriculture is relevant because products need reliable ingredients. Supplier programmes are relevant because Scope 3 emissions sit across the value chain. The manufacturers that treat those areas as one industrial system will have more room to absorb volatility than those that leave them split between departments.
