Sustainable packaging has accumulated a lot of badges, labels and claims. Some tell you something useful about the material. Some tell you about the company supplying it. Others are really disposal instructions rather than certifications at all. Put them all together on a procurement spreadsheet and it can get confusing quite quickly.
For packaging buyers, the useful question is not really, 'Which logo should this box have?' It is, 'What does this claim actually prove?' FSC certification, an OPRL recycling label and ISO 14001 all have value, but they are answering completely different questions. Even the word 'recyclable' needs a bit of interrogation because, on its own, it is a claim rather than a certification.
We hold a number of environmental and wider business accreditations, so there are some good real examples to work with here. The important bit is knowing which ones are relevant to the packaging itself, which ones say something about the supplier, and which should never be treated as shorthand for the whole sustainability story.
Start with the obvious one: FSC®
FSC® certification is probably the most familiar sustainability mark in paper and corrugated packaging. The Forest Stewardship Council runs a certification system for forest-based materials, with Chain of Custody certification used to track eligible FSC material through processing, manufacturing and sale.
That makes FSC particularly relevant when you are buying cartons, paper protection, paper mailers or other fibre-based packaging. It gives you a traceable sourcing claim rather than a vague promise that the material comes from 'responsible forests'.
There is one detail worth keeping in mind, though. Allpack itself is FSC certified, but that does not mean every paper or board packaging item available automatically carries an FSC claim. Our website covers this to help support businesses: only products specifically identified as FSC certified should be treated as such. That is the right way to think about supplier certification generally. A company's accreditation can give you confidence in its systems, but you still need to check the status of the actual packaging specification you are buying.
What should you ask when FSC matters?
If FSC is part of your own procurement policy or a claim you want to pass on to customers, ask which FSC claim applies to the product and make sure the supplier can support it. FSC 100%, FSC Mix and FSC Recycled do not mean exactly the same thing, so 'it's FSC' is not quite enough if the detail matters to your reporting.
You should also keep sourcing and performance separate in your head. An FSC-certified box can still be the wrong size, the wrong board grade or badly suited to the product inside it. Certification gives you evidence about the fibre supply chain. It does not do the packaging engineer's job for you.
Recyclable is important, but it is not a certification
This is probably the biggest terminology trap. 'Recyclable' sounds like a formal status, but in normal packaging language it is an environmental claim. The strength of that claim depends on whether the finished packaging can actually move through the relevant collection, sorting and reprocessing system.
That means the complete pack matters. A corrugated carton may be widely recyclable, but coatings, laminates, windows, labels, adhesives and other components can affect the picture. Likewise, saying a pack is 'paper-based' does not automatically settle the recyclability question.
The Competition and Markets Authority's Green Claims Code is useful here. Environmental claims should be clear, accurate and supported by credible, up-to-date evidence. A business should not imply that an entire product or pack is recyclable when only part of it is, or use broad terms such as 'eco-friendly' without being able to explain what the claimed benefit actually is.
This matters beyond marketing. The CMA published additional supply-chain guidance in January 2026, reinforcing that responsibility for environmental claims does not simply disappear because the wording originally came from a supplier. Ecommerce brands, retailers, manufacturers and distributors all need to understand the claims they are passing along.
RAM is becoming the harder-edged recyclability test
For businesses in scope of Extended Producer Responsibility for packaging, recyclability now has a more formal regulatory side too. The government's Recyclability Assessment Methodology, or RAM, assesses household packaging against the UK recycling system and assigns red, amber or green ratings.
RAM 2027 was published in July 2026 and applies to the 2027 reporting year. The methodology considers collection, sortation, reprocessing and whether the recovered material has a viable end market. Those ratings feed into modulated EPR disposal fees, so recyclability is increasingly a commercial specification issue as well as a customer-facing claim.
Again, RAM is not a sustainability badge to stick on the corner of a parcel. It is a regulatory assessment methodology. But for packaging managers it is increasingly useful evidence when deciding whether a supposedly recyclable specification is likely to stand up to scrutiny.
What OPRL actually means
OPRL stands for On-Pack Recycling Label. The familiar labels are designed to give UK consumers clear instructions about what to do with packaging after use.
It is easy to lump OPRL together with FSC because both can appear as marks on packaging, but they sit at different ends of the process. FSC is concerned with the sourcing and chain of custody of forest-based material. OPRL is concerned with communicating recyclability and disposal information to the person opening the pack.
OPRL membership gives businesses access to its labelling tools and rules, allowing them to determine the appropriate recycling instruction for individual packaging components. OPRL also offers separate recyclability certification services for certain packaging formats, but the standard on-pack recycling label should not itself be treated as a blanket sustainability certification.
For an ecommerce operation, the practical value is customer clarity. If a parcel contains a box, insert, tape and protective material, the customer should not have to guess which pieces belong in which waste stream. Clear component-level labelling can make a well-designed recyclable pack easier to deal with in the real world.
ISO 14001: this one is about the supplier's environmental management
FSC tells you something about forest-based material. OPRL helps communicate disposal. ISO 14001 is different again because it is an environmental management system standard.
We hold ISO 14001 certification. In practical terms, that means its environmental management processes are assessed against an internationally recognised framework covering areas such as environmental impacts, resource management, compliance obligations and continual improvement.
That is useful when you are evaluating the supplier itself rather than one particular roll of tape or carton. If your procurement team has supplier ESG requirements, ISO 14001 gives you something more concrete to work with than a sustainability page full of broad promises.
It does not mean every product a certified business sells is automatically low-impact. That would be stretching the claim much too far. What it does tell you is that environmental management is being handled through a formal, audited system.
EcoVadis: useful for the wider supplier picture
Packaging sustainability does not stop at material choice, especially for larger ecommerce businesses with supplier due-diligence requirements. Our Silver EcoVadis rating looks at the business across a wider set of sustainability themes, including environment, labour and human rights, ethics and sustainable procurement.
That makes EcoVadis more useful for comparing supplier-level sustainability management than deciding whether one particular mailer is recyclable. It can sit alongside your product-level evidence rather than replacing it.
This distinction is quite helpful in procurement. If you want to know whether a corrugated box uses FSC-certified fibre, look at the product and its FSC claim. If you want to know whether the supplier has broader sustainability systems and policies in place, an EcoVadis assessment gives you a different kind of evidence.
Carbon Neutral Britain™: a company-level carbon claim
We also hold Carbon Neutral Britain™ certification. This relates to the company's carbon-neutral certification and wider work around its operational environmental impact.
It is relevant when assessing the environmental credentials of the supplier, but it should not be transferred onto individual packaging products without a separate product-level basis for doing so. Buying a carton from a carbon-neutral-certified business does not make the carton itself 'carbon neutral'.
That may sound obvious written down, but it is exactly the kind of distinction the Green Claims Code is designed to protect. Company claims and product claims need to stay in their proper lanes.
The Bronze FORS accreditation is slightly further from the packaging material itself, but it can still be relevant to a sustainability-focused supplier review. FORS covers fleet operation, including safety, legal compliance and operational efficiency, with environmental performance forming part of the wider scheme.
For a business buying packaging at scale, delivery is part of the supply relationship. It is reasonable to look at how a supplier manages its fleet and distribution as well as what the packaging is made from. Just do not confuse a fleet accreditation with evidence that a particular packaging product is recyclable.
And the certifications that are useful, but not really sustainability certifications
We posses several other certifications and accreditations, including BRCGS, ISO 9001, SafeSupplier, Sedex and SMAS Worksafe. They are valuable in the right procurement context, but there is no need to squeeze every accreditation into an environmental claim.
BRCGS is particularly relevant to customers operating around food packaging and storage standards. ISO 9001 is about quality management. SafeSupplier and Sedex support broader supplier assurance, responsible business and ethical supply-chain due diligence, while SMAS Worksafe focuses on health and safety.
Those things matter. In fact, a genuinely sustainable supply relationship should probably care about quality, ethics and worker safety as well as carbon and recycling. But if the question is specifically, 'What proves this packaging has an environmental benefit?', they are supporting context rather than the main evidence.
So, what should sustainable packaging actually have?
There is no universal checklist where a pack needs FSC, OPRL, ISO 14001 and three other logos before it qualifies as sustainable. The right evidence depends on the claim you are making.
That is a much more useful way to build a packaging specification than asking a supplier for 'the most sustainable option'. You can define the evidence you actually need and then compare products on performance, material use, recyclability, sourcing and cost.
A quick supplier checklist
When a packaging supplier makes an environmental claim, a few fairly ordinary questions will tell you more than a page of green icons.
The logo is the start of the question, not the answer
Certifications are useful because they turn some fairly woolly sustainability claims into things that can be checked. FSC gives you traceability around forest-based materials. ISO 14001 tells you something about the supplier's environmental management. EcoVadis gives you a wider view of business practices. OPRL helps make recycling instructions understandable.
None of them can tell you, on their own, that a pack is the right one for your operation. That still comes down to the product, the material used, how much of it you need, whether the parcel survives transit and what happens to the packaging afterwards.
The better approach is to use certifications for the specific questions they are good at answering, then make the packaging decision on the full picture. It is slightly less tidy than looking for one magic sustainability logo, but it is a lot more useful.
