How to spot ESG greenwashing in fashion claims

Fashion brands now talk about ESG as readily as they talk about fit, colour and fabrication. That does not make an ESG claim false, but it does mean the label can create more confidence than the evidence deserves. To spot greenwashing in ESG claims, we need to separate disclosure from proof, targets from results, and broad corporate language from what is actually happening to fibres, factories, mines and finished products.

In fashion and jewellery, the safest approach is to treat every claim as a statement with a scope. What exactly is being claimed, about which part of the business, over what period, and according to whose method? Once we ask those questions, much of the fog clears. Some claims remain strong. Many turn out to be partial, carefully framed, or too vague to carry the weight of the impression they create.

What ESG means and why it can still mislead

ESG stands for environmental, social and governance. In plain English, it is a way of organising information about how a company manages environmental impacts, labour and human rights issues, and internal oversight such as policies, boards, controls and reporting.

That sounds useful, and often it is. The problem is that ESG is a reporting framework, not a guarantee of responsible products. A business can publish an ESG report, set climate targets, join an initiative, score well on a rating, and still sell clothes made with problematic fibres, unclear sourcing or poor supply-chain visibility.

In fashion, this confusion happens for a few reasons.

First, ESG disclosure is often company-level. It may tell us about office electricity, packaging reductions, or governance processes, while saying much less about the biggest impacts in the value chain, such as raw material production, dyeing, finishing, wet processing, subcontracting and end of life.

Second, targets can be mistaken for outcomes. “We aim to use more preferred fibres by 2030” is not the same as “this garment contains verified lower-impact material today”. Ambitious language can make a business sound further along than it is.

Third, ESG ratings do not all measure the same thing. Some focus heavily on whether a company has policies, systems and disclosures in place. That matters, but policies are not proof that a cotton crop used less water, that a tannery controlled hazardous chemicals, or that a recycled fibre was physically present in the product sold.

Fourth, the term itself carries a halo effect. Consumers see ESG and assume ethical sourcing has been checked in detail. Small businesses may assume a supplier with an ESG deck has already done the hard work. Often, the deck is only the starting point.

This is why Greenwashing and ESG now sit so close together in fashion conversations. The issue is not that ESG is meaningless. It is that ESG can be used to signal responsibility more broadly than the underlying evidence supports.

The greenwashing patterns that appear in fashion ESG claims

The most common pattern is selective measurement. A brand highlights one metric that improved, such as reduced plastic packaging or lower emissions from owned operations, while the more material impacts sit elsewhere. In fashion, most impacts are usually in the supply chain rather than the head office. If a claim centres on what the company directly controls and leaves out mills, dye houses, farms, mines or subcontractors, we should read it carefully.

A second pattern is vague language. Words such as “conscious”, “responsible”, “sustainable”, “eco” and “better” can create a strong impression while saying almost nothing measurable. If a label says “responsibly sourced wool” or “sustainable gold tone finish”, we need to know what standard, what sourcing route, and what evidence sits behind those words.

A third pattern is the use of partial material truths. A garment may contain a preferred fibre, but only in a small percentage. A brand may spotlight recycled polyester while saying little about microfibre shedding, blend complexity, or whether the rest of the garment is conventional virgin material. Jewellery can present “recycled silver” as a complete ethical answer when the claim does not address stone sourcing, plating chemistry, labour conditions or traceability.

A fourth pattern is overreliance on carbon offsets. Offsets can be presented as if they erase impact at source. In reality, an offset claim is not the same as reducing emissions in fibre production, manufacturing, transport or use. If a brand says a collection is “carbon neutral”, the immediate question is how much was reduced within its own value chain and how much was balanced through purchased credits.

A fifth pattern is supplier blind spots. Brands sometimes make polished ESG claims based on tier 1 factory relationships while having limited visibility into tier 2 and tier 3, where spinning, weaving, dyeing, tanning, smelting and raw material extraction happen. Yet these stages often carry major environmental and human rights risks.

A sixth pattern is swapping company progress for product proof. A business may say it has signed a responsible sourcing code, mapped a percentage of suppliers, or improved audit coverage. Those may be positive steps, but they do not automatically prove that a specific dress, ring or pair of trainers meets the impression created in marketing.

We see a related issue in the way percentages are framed. “Ninety per cent of our cotton is more sustainable” sounds impressive until we learn the term covers several different schemes with different levels of assurance, or that cotton makes up only part of the total fibre mix. The same applies to claims about “certified factories” without explaining whether certification covers quality management, social compliance, chemical management or environmental performance.

If you want a broader checklist for consumer-facing claims, our guide to how to spot fashion greenwashing before you buy pairs well with ESG-specific reading.

How to read the evidence behind a claim

When we assess a claim, we start with scope. Is the claim about a company, a product line, a single product, or one component within that product? “Our brand uses recycled materials” is very different from “this coat contains 80 per cent recycled wool, verified through chain of custody”.

Next, check the baseline. If a brand says it has “cut emissions” or “reduced water use”, compared with what year, what business size, and what method? Growth can complicate the picture. A company may reduce emissions intensity per item while total emissions still rise. Neither figure is useless, but they tell different stories.

Timeframe matters too. Is this a current claim, a future target, or a historic achievement? “By 2030” language belongs in the target category. It should not be allowed to blur into the impression that the issue has already been solved.

Methodology is another key test. If a claim relies on a life cycle assessment, was it product-specific or based on generic datasets? Was it cradle-to-gate or cradle-to-grave? Were assumptions made about consumer use, washing frequency, repair and disposal? We do not need every shopper to become a technical reviewer, but we do need enough information to see whether the claim is robust or selectively constructed.

Supply-chain coverage often reveals the real strength of a statement. Ask which tiers are included. Tier 1 is cut, sew and final assembly. Tier 2 may include fabric mills and processors. Tier 3 can include spinning, dyeing inputs and earlier transformation stages. Beyond that lie farms, forests, oil extraction or mining. A claim that stops at tier 1 may leave the highest-risk stages untouched.

Then ask what exactly is being counted. Is a recycled content claim based on the whole product, the textile shell only, or one trim? Is a chemical management claim about restricted substances in the final product, or about wastewater and process chemicals in manufacturing? Is a “traceable” jewellery claim referring to precious metal, gemstone, or both?

The distinction between product, fibre and company is one of the most important ways to spot Greenwashing and ESG overreach. A company may have a climate strategy. A fibre may carry a certification. A product may contain only a fraction of that fibre, mixed with other materials of unknown origin. Marketing often compresses these layers into one reassuring message. We should pull them apart again.

What certification can and cannot tell you

Certification can be valuable, but only if we understand what each scheme covers and what it does not.

For fibres, some standards focus on how a raw material is produced. Organic standards for cotton, for example, address agricultural practices and inputs. Forest-based fibre standards may focus on forest management or responsible sourcing of wood inputs. Animal fibre schemes may address land management or animal welfare criteria. None of these automatically covers every stage after the farm or forest unless paired with additional chain-of-custody certification.

Chain of custody matters because it addresses whether certified material is kept separate, physically mixed under controlled rules, or accounted for through a mass balance system. Those are not interchangeable. A consumer reading “contains certified material” may assume physical traceability through the product. The scheme may actually allow controlled mixing and accounting rather than one-to-one physical segregation.

For chemicals, standards and programmes can cover different things. Some focus on restricted substances in finished products. Others address input chemistry, wastewater, sludge, or broader environmental management in processing facilities. A claim that a product is “non-toxic” is usually too broad to be meaningful. A claim tied to a recognised chemical management standard is better, but we still need to know whether it covers the finished item, the process, or both.

For recycled content, certification can help verify whether a stated percentage comes from pre-consumer or post-consumer sources and whether chain-of-custody controls exist. But it does not automatically tell us about durability, shedding, recyclability at end of life, or the impacts of blending recycled synthetics with other fibres.

In jewellery and mining, responsible sourcing schemes can improve due diligence and traceability for certain metals or stones, but they rarely solve every issue in one stroke. A certification may cover a mine, a refiner, a chain-of-custody process, or a code of practices for members. That is useful. It is not the same as proving complete transparency for every component in a finished piece.

This is why we are careful not to treat certification as a magic stamp. A strong claim usually combines a relevant standard, clear scope, and honest wording about limits. If a brand uses certification language to imply more than the scheme actually verifies, that is a warning sign.

What UK and EU rules mean for fashion marketing now

In the UK, environmental marketing claims are already governed by general consumer protection law. The Competition and Markets Authority has published the Green Claims Code, which says claims should be truthful and accurate, clear and unambiguous, not omit important information, make fair comparisons, consider the full life cycle where relevant, and be substantiated.

The Advertising Standards Authority also applies the CAP Code to ads and has upheld complaints where environmental claims were likely to mislead. In practice, that means broad statements such as “sustainable” or “eco-friendly” need solid evidence and careful qualification. It also means qualifications cannot be buried where the main impression still overstates the benefit.

For UK readers, the key point is that a claim can be problematic even without a sector-specific fashion law. General consumer law still bites if the overall impression is misleading.

In the EU, the direction of travel is more prescriptive. The Empowering Consumers for the Green Transition rules are intended to tighten how generic environmental claims and labels are used in consumer marketing. Alongside that, the proposed Green Claims Directive has aimed to require stronger substantiation and verification for explicit environmental claims, though the legislative picture can shift before final implementation. For brands selling into the EU, this means broad green language is becoming harder to defend without detailed evidence.

Corporate disclosure rules matter too, but in a different way. The EU Corporate Sustainability Reporting Directive increases sustainability reporting obligations for many companies in scope. That may improve the amount of information available, but more disclosure does not automatically mean better products. We still need to distinguish between reporting compliance and substantiated marketing claims.

There are also supply-chain due diligence developments in Europe, and product-specific initiatives such as the EU strategy for sustainable and circular textiles. These affect the wider compliance context, data expectations and future product information requirements.

The UK is not simply identical to the EU here. UK businesses and UK consumers operate under UK consumer protection and advertising rules, while EU rules may apply where products are marketed or sold into EU member states. Small fashion businesses in Britain should therefore check both the home market rules and the destination market rules if they sell cross-border.

Questions to ask before trusting an ESG claim

A few questions will usually tell us whether a claim is solid or mostly styling.

What is the claim actually about? Is it about the whole company, one collection, one product, one fibre, one component, or one stage of production?

What evidence is named? Look for a standard, report, methodology, audit scope, chain-of-custody model, or supplier programme. If the claim relies on mood words alone, that is weak.

Is the wording specific? “Contains 70 per cent recycled cotton certified through chain of custody” is specific. “Made more responsibly” is not.

What is the baseline and timeframe? Reduced compared with when, and over what period? Is this a current fact or a future target?

How much of the supply chain is covered? Does the evidence stop at final assembly, or does it include spinning, weaving, dyeing, tanning, refining, mining or farming?

Is the claim material to the product? A recycled hangtag does not make a high-impact garment low impact. A cardboard box redesign is not the same as responsible fibre sourcing.

Does the claim confuse policy with outcome? A supplier code of conduct, ESG strategy or net zero roadmap may be relevant, but none is proof on its own that the product in front of us is responsibly made.

Are offsets doing too much work? If the climate claim depends heavily on offsets, ask what was reduced in the real supply chain first.

Does certification match the message? A standard may verify one aspect only. Make sure the marketing has not stretched that narrow assurance into a broad ethical conclusion.

What is not being said? Silence can be informative. If a brand talks at length about packaging and says almost nothing about materials, wet processing or sourcing geography, the omission may tell us where the unresolved issues are.

For small fashion businesses, these questions are just as useful when assessing suppliers as when assessing competitors. Ask for transaction certificates where relevant, not just logos on a presentation. Ask whether recycled content is product-level or portfolio-level. Ask whether traceability refers to physical segregation, mass balance, or supplier declarations. Ask whether social compliance data covers subcontracting and unauthorised production. Good suppliers will recognise these as normal commercial questions.

Spotting Greenwashing and ESG inflation is less about cynicism than precision. We do not need to dismiss every ESG claim. We need to read it at the right level, with the right boundaries in mind. Once we do that, the difference between a meaningful statement and a marketing gloss becomes much easier to see.
