Barry Callebaut links Arla dairy sourcing to carbon data

Barry Callebaut has launched a three-year dairy decarbonisation partnership with Arla Foods, starting with skimmed milk powder sourced from the UK. The FarmAhead Customer Partnership programme links the dairy volumes supplied to Barry Callebaut with farm-level carbon data and emissions-reduction activity across the shared supply chain.

Arla will provide annual primary carbon-footprint data linked to the relevant volumes at farm level. Reporting will be aligned with recognised greenhouse gas and dairy carbon methodologies, while participating farmers can receive incentive payments for practices intended to reduce emissions.

The arrangement brings dairy sourcing more directly into Barry Callebaut’s Scope 3 programme. Dairy remains an important ingredient across milk chocolate, fillings, coatings, and other products, while most of the associated agricultural emissions occur before milk reaches the ingredient processor or chocolate factory.

Tilmann Silber, head of Net Zero at Barry Callebaut, said: “Decarbonizing dairy is essential to reducing our carbon footprint.” The company is using the partnership to improve transparency around dairy emissions and create a route for funding reductions at farm level.

Arla’s FarmAhead model already combines farm measurement with an incentive mechanism. Its climate check uses more than 200 data points for participating farms, while the incentive model rewards specified actions through the milk price rather than simply paying farms for having a lower starting footprint.

Those actions can include measures around feed efficiency, manure handling, renewable electricity, and other farm practices. For an ingredient customer, the structure provides a link between purchased dairy volumes and primary data from the farms supplying the milk, rather than relying solely on generic emissions factors.

Scope 3 emissions can account for most of a food company’s footprint, yet the manufacturer often has limited direct control over the agricultural activity that creates them. Supplier programmes therefore depend on credible measurement and commercial mechanisms that reach further upstream than a conventional ingredient specification.

The Barry Callebaut and Arla programme addresses that gap through collaboration rather than ownership. Arla retains the direct relationship with its farmer owners and the systems used to collect farm data, while Barry Callebaut gains a defined mechanism for connecting its dairy purchases with emissions-reduction activity upstream.

The initial focus on skimmed milk powder also gives the programme a bounded starting point. Milk powder passes through several processing stages before it enters chocolate manufacturing, so annual farm data has to remain traceable through a supply chain that includes raw milk collection, dairy processing, ingredient supply, and final chocolate production.

That traceability is central to the credibility of any product or corporate carbon claim. A manufacturer can only use primary supply-chain data effectively if the methodology, volume allocation, and reporting boundaries remain consistent enough to withstand internal and external scrutiny.

Barry Callebaut has set a target to reduce total emissions by 30% by 2030 against a 2021/22 base year and to reach net zero by 2050. Its latest sustainability reporting identifies dairy among eight priority raw materials — alongside cocoa, sugar, palm, coconut, soy, vanilla, and hazelnuts — that together account for 97% of total raw-material volume.

Dairy therefore sits inside a broader sourcing programme rather than as a stand-alone climate project. The group has already identified supplier engagement and lower-carbon dairy farming among the levers in its Net Zero roadmap, alongside factory energy, transport, cocoa farming, and other agricultural measures.

The Arla partnership gives that roadmap a specific commercial vehicle. Annual data should allow the parties to compare progress over the three-year period, while the incentive structure gives farmers a financial reason to implement selected measures instead of treating emissions reduction as an unfunded customer requirement.

For Arla, the agreement extends FarmAhead into another industrial ingredient relationship. The programme has already been used with customers seeking farm-level climate data for their own reporting, and the Barry Callebaut arrangement applies the model to a supply chain in which milk is processed into powder before becoming one component of a finished chocolate product.

That extra processing step does not remove the agricultural emissions attached to the ingredient. It does, however, make allocation and reporting more complex, particularly when milk from many farms is pooled before processing and the resulting powder is supplied into multiple products and markets.

The three-year structure should provide enough time to test whether the accounting and farm interventions remain workable beyond a single reporting cycle. It also gives Barry Callebaut a basis for deciding whether the model can be expanded to additional dairy volumes or geographies.

The first measure of success will be whether annual primary data can be linked consistently to purchased volumes, and whether the funded farm actions produce reductions that can be evidenced over time. If that holds, the partnership gives Barry Callebaut a repeatable route for addressing a Scope 3 category that cannot be decarbonised from inside a chocolate factory.
