P&G Supplier Requirements: Carbon Reporting, Greenchain and EcoVadis

If you supply Procter & Gamble, or you're bidding to, carbon data can now form part of how your offer is assessed. For relevant suppliers, three important pieces of the sustainability picture are the carbon footprint of the materials you supply, your material-level GHG reduction plan, and your EcoVadis assessment. 

P&G doesn't publish a penalty for not having those things. But it could still cost you work. If a competitor puts a credible product carbon footprint in front of a buyer and you can't, they score on a criterion where you score nothing, and that can be the difference at renewal or in a competitive tender.

This guide covers what P&G Supplier Citizenship is, the climate targets behind it, which suppliers are in scope, what you have to produce, how it gets submitted, where EcoVadis fits, and what happens if you fall short.

What Is P&G Supplier Citizenship? 

Procter & Gamble is one of the world's largest consumer goods manufacturers, with brands spanning fabric care, home care, baby care, grooming and personal health.

Supplier Citizenship is how P&G sets expectations for its external business partners. It covers three areas: Responsible Sourcing (human rights, labour standards and ethics), Supplier Diversity, and Climate.

Two tools carry these expectations, and they work at different scales. EcoVadis is P&G's broader supplier assessment, used across Supplier Citizenship as a whole rather than the Climate strand alone. It covers environment, labour and human rights, ethics, and sustainable procurement together. Greenchain sits specifically inside the Climate strand. It's where P&G collects the two carbon-specific deliverables set out in its Supplier Greenhouse Gas Reduction Playbook, published in 2025: a product carbon footprint and a GHG reduction plan, both at material level.

Both tools are covered in detail below, and both can contribute to how P&G evaluates supplier performance and sourcing opportunities.  

What are P&G's climate targets and key dates?

P&G announced its Net Zero ambition in 2021, alongside an intermediate target for this decade.

With P&G reporting a roughly 9% reduction against a 40% 2030 target, supplier engagement is becoming an increasingly important part of its strategy. P&G says supplier GHG reductions and innovative solutions are critical to achieving its goals because purchased materials are within the scope of its supply chain target. 

That framing is worth understanding. The emissions you generate making the materials P&G buys land in P&G's Scope 3. Reducing these emissions is something P&G can only do with its suppliers, which is why the request lands with you rather than being handled internally. 

Which P&G Suppliers Need to Report Carbon Data? 

Scope depends on which part of Supplier Citizenship you're being asked about. EcoVadis is the broader net. Because it's used across Supplier Citizenship as a whole, not just the Climate strand, you can be asked to complete it whatever you supply, whether or not the Greenchain requirements below apply to you.

Greenchain is narrower. It's aimed specifically at suppliers of raw materials, packaging, and contract manufacturing, set out in P&G's Supplier Greenhouse Gas Reduction Playbook. Within that group, P&G prioritises what it calls high impact materials:

• Surfactants
• Polymers
• Solvents
• Inorganics
• Non-wovens
• Super absorbents
• Perfumes
• Rigid packaging

Supply one of these and expect more specific calls to action, sometimes including a deep dive Life Cycle Assessment on a priority material or project. Supply something outside that list and the Greenchain ask is lighter but not absent. P&G says criteria are clarified by your individual Purchases contact, based on your materials' exposure to greenhouse gas emissions. There's no published threshold, so the honest answer to "does this apply to me" is a conversation with your buyer.

What are P&G's supplier carbon reporting requirements?

P&G's climate requirements run through two separate tools, working at two different levels: an EcoVadis assessment at organisational level, and Greenchain submissions at material level. Depending on what your Purchases contact asks for, you may need one or both.

EcoVadis

P&G uses EcoVadis to assess supplier social and environmental risk across Supplier Citizenship as a whole, and runs a dedicated invitation and registration page for its suppliers. Unlike the Climate-specific tools covered next, EcoVadis spans four themes: Environment, Labour and Human Rights, Ethics, and Sustainable Procurement.

Carbon sits within the Environment theme, and the assessment rewards evidence over intent. A footprint measured to a recognised methodology, with third-party support behind it, scores better than a stated commitment. Our guide on how to improve your EcoVadis score covers how carbon data feeds the Environment section and what documentation analysts accept.

Your Product Carbon Footprint (PCF)

P&G's Climate page sets out three calls to action: share your products' carbon footprint, share your GHG reduction plan, and leverage P&G support. The first two, unlike EcoVadis, are submitted through Greenchain, and both sit at material level. 

Your PCF is calculated using PACT methodology. PACT is the Partnership for Carbon Transparency, hosted by the World Business Council for Sustainable Development, which has developed a common approach to product-level emissions calculation and exchange.

Three qualities are specified:

• Quality data. High specificity, using primary data where possible rather than industry averages.
• Granularity. Emissions split across Scopes 1, 2 and 3, per material.
• Transparency. Sharing data openly, including the challenges behind it.

P&G's approach also places greater emphasis on supplier-specific data, which means businesses may need to engage their own suppliers to improve the quality of the Scope 3 data underpinning their PCFs. 

Your GHG reduction plan for P&G materials 

This is a material-level plan, not an organisational one, covering the specific materials you supply to P&G. Submitted through Greenchain alongside your PCF. P&G wants suppliers past the plan-writing stage and into delivery. The four asks are: 

• Integrate your GHG plan into your business strategy, and work with P&G to identify joint value creation opportunities
• Take accountability to lead and develop your own plans
• Implement your own direct interventions to reduce emissions
• Continue to deliver against P&G's Responsible Sourcing Expectations for External Business Partners

What is a Product Carbon Footprint, and how is it different from a company carbon footprint?

Product and company carbon footprints sound similar, so it’s worth clearly separating the two to avoid confusing suppliers. A company carbon footprint measures the emissions of your whole organisation across Scopes 1, 2 and 3, in line with the GHG Protocol. It's the basis for reporting like B Corp or a client questionnaire, covers the Scope 1 and 2 data that frameworks like SECR require, and is what underpins a strong EcoVadis submission, since EcoVadis assesses your organisation at corporate level.

A product carbon footprint measures the emissions associated with one product or material, per unit, within a defined boundary such as cradle to gate. It's built from the process and activity data specific to producing that item, energy used, materials consumed, transport involved, rather than a slice allocated from your total footprint.

Through Greenchain, P&G asks for the second: a PCF at material level. You don't strictly need an organisational footprint to build one. But in practice, much of the data a PCF draws on, energy use, fuel, key processes, overlaps with what a company-wide footprint measures, so having one already gives you a running start and a way to sense-check the numbers.

One useful feature of the PACT approach is that it is a standard rather than a P&G-specific format. P&G notes that PCFs calculated to PACT can be shared with customers other than P&G, so the work is reusable.

The same practical logic applies to your reduction plan. P&G asks for it at material level, but it's easier to prioritise and justify material-level actions once you understand where your organisation's emissions sit as a whole.

How Does P&G Greenchain Work? 

P&G collects supplier climate data through Greenchain, its climate data exchange platform, which gathers Product Carbon Footprints and associated GHG reduction plans at material level.

There are two submission routes:

Two practical steps P&G asks high impact materials suppliers to take: assign a sustainability manager in Greenchain and set up a system to exchange data per the PACT API specification.

P&G says it will use Greenchain data for reporting, tracking, analytics and decision making, and prioritises high GHG impact materials for collection.

On timing, P&G does not publish a fixed annual supplier deadline in the way some programmes do. Expectations are set through your Purchases contact, so ask directly rather than waiting to be chased. That is different from, say, Walmart's Project Gigaton, which runs a set autumn reporting window.

What Happens If a P&G Supplier Doesn't Provide Carbon Data? 

P&G does not publish a carbon-specific penalty or delisting policy. But the outputs covered above, your product carbon footprint, your material-level GHG reduction plan, and your EcoVadis score, don't just sit on file. They feed into Best Total Value, one of P&G's five global sourcing principles, which P&G uses to make its sourcing decisions.

P&G's own wording is that sourcing decisions are driven by total cost of ownership, quality, supplier responsiveness and account service, speed to market, social and environmental impact, and a supplier's willingness to share risk or provide resources. Environmental performance, including carbon data, sits within that combined social and environmental impact factor, alongside your EcoVadis score, GHG reduction plan and product carbon footprint.

It's also worth knowing that P&G's stated preference is for continuity. It says it favours ongoing relationships with incumbent suppliers, and that new suppliers must offer meaningfully better total value to win business over one already in place. That cuts both ways for carbon reporting: for an incumbent supplier, weak carbon data could become a disadvantage; for a prospective supplier, strong carbon data gives buyers another way to demonstrate environmental performance and total value.

P&G's own call to action to high impact materials suppliers is to include PCF data, GHG reduction plans and value propositions in your next offers. That makes this more than a corporate reporting exercise: for relevant suppliers, carbon data can become part of the commercial conversation. 

So the realistic risk is not a formal sanction. It is scoring weaker on a factor your competitors are scoring stronger on, at renewal or in a competitive tender, and never being told that was the difference. Add the cost of being asked at short notice with no data ready, and the position gets uncomfortable quickly.

The pattern is repeating across large buyers. We have covered Apple's Supplier Code of Conduct, Microsoft's supplier sustainability reporting and CDP Supply Chain reporting separately. The requirements differ in detail. The direction does not.

What Support Does P&G Offer Suppliers? 

P&G runs a Climate Unlock Program with six free resources, split between suppliers getting started and those further along:

Accelerate is free for P&G suppliers, with a financial obligation only if you choose to purchase renewable electricity through it.

The Scope 1 & 2 toolkit is worth reading if you run manufacturing sites. It covers four areas: setting up a sustainability management programme, energy and water monitoring and analytics, thermal studies, and renewable electricity sourcing. 

Two caveats. P&G states these are its own best practices and recommendations, and that suppliers remain responsible for their own decisions and execution. And these resources stop short of doing the carbon accounting itself: none of them measure your organisational footprint, calculate a PACT-aligned product carbon footprint, or build a quantified reduction plan against it. That's exactly where Seedling can help. 

How Seedling helps P&G suppliers report emissions

Most of what P&G is asking for is carbon accounting work: a defensible organisational footprint, product-level data built from it, a quantified reduction plan, and evidence strong enough to hold up in an EcoVadis assessment.

Seedling pairs carbon accounting software with one-to-one support from a dedicated carbon expert. For suppliers responding to P&G, that means we can:

• Measure a full-scope footprint across Scopes 1, 2 and 3, aligned to the GHG Protocol and expert-reviewed. This is the practical starting point for both an EcoVadis submission and material-level PCF work.
• Produce product carbon footprints at material level, so you can answer material-specific requests rather than offering a company-wide figure.
• Go beyond spend-based data. Spend data is a reasonable starting point, but P&G asks for primary data where possible. We help you collect the activity data that makes a footprint accurate, and makes reductions visible year on year.
• Collect data from your own suppliers. Our supplier engagement tool lets you request emissions data that feeds straight into your footprint, which is what cascading PCF requests down your chain requires in practice.
• Build a quantified reduction plan with SBTi-aligned Net Zero targets, modelling the impact of specific changes rather than listing intentions.
• Strengthen your EcoVadis submission with assured emissions data and documentation that meets the evidence standards analysts apply.
• Keep your data reusable, so the same footprint serves P&G, your other customers, ISO 14064 verification, B Corp, SECR and your own reporting. Our guide on how to report carbon data to clients covers the general case.

We work with manufacturers and mid-market suppliers across the UK and beyond, typically without a full-time sustainability team, and the process takes around a day of your time in total.
