For UK food and grocery suppliers, sustainability is no longer a “nice to have” conversation that sits alongside commercial negotiations. It is increasingly part of them.
Across the sector, the big retailers are tightening expectations around carbon reporting, Scope 3 emissions and wider compliance. For suppliers, that shift brings a growing sense of pressure. Not just to disclose data, but to demonstrate credible progress, clear plans and alignment with supermarket climate goals.
Why Scope 3 has become the real battleground
Supermarkets have made significant progress in reducing emissions from their own operations. The harder challenge lies further upstream.
Scope 3 emissions, which include farming, manufacturing, transport and packaging, account for the overwhelming majority of a retailer’s total carbon footprint. In many cases, they represent more than 90% of overall emissions. That reality leaves retailers with limited options. If they want to meet their net-zero commitments, suppliers have to be part of the solution.
This is why Scope 3 has moved from being a long-term ambition to an immediate commercial priority. As Andy, Achieve Goal 12’s Founder recently highlighted in The Grocer, retailers are now grappling with how to persuade suppliers to act without destabilising already stretched supply chains.
That tension between ambition and practicality sits at the heart of today’s sustainability debate.
Through direct research into supermarket sustainability frameworks, AG12 has seen a clear pattern emerge. While retailers are taking slightly different routes, expectations are converging around a few core themes: transparency, measurable targets and evidence of action.
Tesco, for example, has put significant emphasis on supplier data. Its Scope 3 programme requires suppliers to report emissions annually and to work towards science-based targets aligned with Tesco’s own net-zero commitments. To balance those expectations, Tesco has introduced sustainability-linked supply chain finance, signalling that disclosure and progress can be commercially rewarded.
Sainsbury’s approach places strong emphasis on collaboration. Its ambition to reach a net-zero supply chain by 2030 relies heavily on suppliers setting 1.5°C-aligned targets and sharing emissions data. Rather than focusing solely on enforcement, Sainsbury’s has invested in joint action groups and shared tools designed to help suppliers build capability over time.
Marks & Spencer’s Plan A has long positioned sustainability as integral to buying and sourcing decisions. Public commentary from M&S leaders consistently frames Scope 3 as the single biggest challenge in delivering meaningful carbon reduction. For suppliers, alignment with Plan A is increasingly tied to long-term partnership rather than short-term compliance.
Aldi’s model is quieter but no less influential. Its supplier scorecards incorporate environmental performance metrics, meaning carbon and sustainability are now embedded in how suppliers are evaluated commercially. While the requirements may appear lighter on the surface, expectations are still very much present.
Along with the retailers mentioned above, Morrisons, Coop, Waitrose, ASDA and Lidl all have similar initiatives to drive emissions reductions in the supply chain.
Alongside individual retailer programmes, collaboration is growing at sector level. Initiatives such as WRAP’s Retailer Net Zero Collaboration Action Programme aim to standardise Scope 3 measurement and reporting, reducing duplication while raising the baseline for everyone involved.
Incentives or enforcement? The balance is shifting
Supermarkets are moving away from purely enforcement-led approaches.
Delisting or penalising suppliers for failing to meet carbon targets may feel decisive, but it risks damaging supply resilience and disproportionately impacting smaller businesses. Retailers increasingly recognise that pressure alone does not deliver progress.
Instead, we are seeing a more nuanced balance emerge. Incentives such as preferential payment terms, access to finance, and long-term contract security are being used alongside clear expectations. Retailers are also investing more in supplier education, shared data platforms and collaborative forums.
The message is changing. Sustainability performance still matters, but so does a supplier’s willingness to engage, improve and be transparent. Progress is becoming as important as perfection.
What supermarkets now expect from suppliers
While requirements continue to evolve, most major supermarkets now expect suppliers to have a basic but credible sustainability foundation in place.
That typically includes regular emissions reporting, particularly for high-impact categories, alongside clear plans for reduction. Many retailers now expect suppliers to be working towards science-based targets or to be able to explain how their plans align with recognised climate frameworks.
There is also a growing focus on data quality and verification. Retailers are under increasing scrutiny themselves, which means supplier data must stand up to challenge. Transparency is no longer optional.
How suppliers can prepare without panic
For suppliers, the most important step is to move early and deliberately, rather than reactively.
Understanding where emissions sit across your operations and supply chain is the starting point, even if the data is not perfect at first. Retailers are generally more receptive to honest baselines than to last-minute, rushed submissions.
Equally important is setting realistic targets and being able to explain how they will be achieved. Suppliers who can demonstrate a clear roadmap, even one that spans several years, are far better placed than those who wait for exact instructions from retailers.
Engagement matters too. Suppliers who take part in retailer-led initiatives, workshops and pilot programmes are more likely to receive support rather than sanctions. Sustainability is increasingly relational, not just technical.
Finally, many suppliers will benefit from external support. Specialist tools, advisors and platforms can accelerate progress, particularly for businesses without in-house sustainability expertise.
At Achieve Goal 12, our work with suppliers and retailers alike shows that meaningful progress happens when expectations are clear, incentives are aligned and collaboration is genuine.
