A brand's sustainability report is one of the few places where a company is expected to show its working — not just tell you it cares about the planet, but demonstrate it with numbers, timelines, and third-party verification. Most shoppers never open one. The ones who do often close it again within minutes, defeated by corporate language and charts that seem designed to impress rather than inform. This guide walks you through the process, step by step, so you can read one with clear eyes.
Key takeaways
- The absence of a sustainability report is itself a signal worth noting.
- Absolute emissions figures (total tonnes of CO2) tell you more than intensity ratios (emissions per garment), which can fall even as a brand grows and pollutes more overall.
- Third-party verification is the single fastest check: if no independent auditor has signed off on the data, treat every number as a claim, not a fact.
- Brands that set targets without base-year data are asking you to trust a promise with no starting point.
- The Ellen MacArthur Foundation publishes free guidance on circular economy metrics that gives you a useful benchmark for what good reporting looks like in fashion.
What you need before you start
- A laptop or tablet (sustainability reports are often long PDFs — a phone screen will frustrate you)
- The brand's website address
- A notes app or a piece of paper to jot down what you find and what is missing
- About thirty minutes for your first report; it gets faster with practice
Step 1: Find the report — and notice if it does not exist
Go to the brand's website and scroll to the footer. Look for links labelled 'Sustainability', 'Impact', 'Responsibility', or 'ESG'. Larger brands often publish a dedicated annual report as a downloadable PDF; others fold the information into a webpage. If you cannot find anything after two minutes of looking, search the brand's name alongside the words 'sustainability report' or 'impact report' in your browser.
Expected result: You either have a document or a dedicated page in front of you, or you have confirmed that no such thing exists. Both outcomes are informative. A brand that sells itself on its environmental values but publishes no structured account of them is telling you something.
A missing report does not automatically mean a brand is behaving badly — very small independent labels may not have the resources to produce one. But for any brand with significant scale, the absence of public data is worth questioning.
Step 2: Check the date and the scope
Before reading a single word of the content, find the publication date and the reporting period it covers. Sustainability reports are typically published annually and cover the previous calendar or financial year. If the most recent report is more than two years old, the brand is not keeping pace with its own commitments.
Next, check the scope. Does the report cover the brand's own operations only — its offices and stores — or does it extend to its supply chain? Supply chain emissions (what the industry calls Scope 3) are almost always the largest share of a fashion brand's environmental footprint, because they include the energy used to grow fibres, spin yarn, weave fabric, and cut and sew garments, often across multiple countries. A report that stops at the brand's own walls is leaving out most of the story.
Expected result: You know how current the data is and whether the supply chain is included. If it is not, note that gap.
Step 3: Look for absolute numbers, not just ratios
This is the step most readers skip, and it is where the most important information lives. Brands sometimes report progress in relative terms — 'we reduced emissions intensity by 20 per cent per garment' — while their total emissions have risen because they are producing and selling far more. Relative improvements can be genuine progress, but they can also mask overall growth in harm.
Look for absolute figures: total tonnes of greenhouse gas emitted, total litres of water consumed, total weight of textile waste sent to landfill. Then look at whether those numbers are going up or down over time. A brand that shows you a multi-year trend in absolute terms is giving you something you can actually evaluate.
Research into the fast fashion model has consistently shown that volume growth is one of the primary drivers of the industry's environmental burden, which is why absolute figures matter so much more than per-unit ratios.
Expected result: You have noted whether the brand reports absolute or relative figures, and whether a multi-year trend is visible.
If a brand only shows you one year of data with no prior comparison, you have no way of knowing whether things are improving or not. That is not transparency — it is a snapshot presented as progress.
Step 4: Find the third-party verification statement
Anyone can write numbers into a report. The question is whether an independent organisation has checked them. Look for a section called 'assurance', 'verification', or 'independent review'. It will usually appear near the end of the document and will name the auditing firm and the standard they applied.
If there is no assurance statement, every figure in the report is self-reported. That does not make it false, but it means you are relying entirely on the brand's own word. Many smaller brands do not yet commission external assurance — but the largest ones have no good excuse for omitting it.
Also look for recognised certifications referenced in the report: GOTS (Global Organic Textile Standard), bluesign, Fair Trade, or B Corp status, for example. These are awarded by independent bodies and carry more weight than a brand's own language about its values.
Expected result: You know whether the data has been independently verified and which, if any, external certifications the brand holds.
Step 5: Read the targets — and look for the base year
Most sustainability reports include a section on future commitments: 'we will reach net zero by 2040', 'we will use 100 per cent recycled materials by 2030'. These targets are only meaningful if the report also tells you where the brand is starting from.
Look for a base year — the year against which progress will be measured — and check whether the brand reports its current position relative to that baseline. A target without a base year is a wish. A target with a base year and annual progress data is a commitment you can hold the brand to.
Also pay attention to the language around targets. 'We aim to' and 'we are committed to exploring' are softer than 'we will' or 'we have committed to a Science Based Target'. The Science Based Targets initiative (SBTi) is a credible external framework that aligns corporate climate targets with climate science — its presence in a report is a positive signal.
Expected result: You can see what the brand has promised, when it promised to deliver, and whether it is on track.
Step 6: Notice what is not there
This is the most subjective step, and often the most revealing. After reading the report, ask yourself what you expected to find that was absent.
Common omissions include: wage data for garment workers, the percentage of the supply chain that has been audited, the volume of unsold stock and how it is handled, and water stress data for the regions where the brand sources its fabric. The Ellen MacArthur Foundation has published detailed frameworks for what genuinely circular fashion reporting should include — these are freely available and give you a useful checklist.
A brand like Patagonia has long published granular supply chain data alongside its environmental commitments, including its involvement in land conservation initiatives. That level of specificity is a useful benchmark for what detailed, substantive reporting can look like.
Expected result: You have a short list of the topics the report did not address. That list is part of your overall assessment.
Greenwashing rarely involves outright lies. It more often involves careful selection — reporting the metrics that look good and staying quiet about the ones that do not. The gaps in a report are as important as its contents.
Troubleshooting
The report is a PDF of 150 pages and I do not know where to start. Use the document's search function (Ctrl+F or Cmd+F) and search for 'emissions', 'water', 'waste', 'supply chain', and 'assurance'. Jump to those sections first.
The brand uses a lot of technical language I do not recognise. Terms like 'Scope 1, 2 and 3 emissions' refer to direct emissions from owned operations (Scope 1), indirect emissions from purchased energy (Scope 2), and all other indirect emissions including the supply chain (Scope 3). 'GHG' means greenhouse gas. 'tCO2e' means tonnes of carbon dioxide equivalent — a standard unit for comparing different greenhouse gases.
The brand does not publish a standalone report but has a sustainability page on its website. Apply the same steps. Look for numbers, dates, third-party verification, and targets with base years. A webpage can be just as rigorous as a PDF — or just as vague.
I cannot tell whether the certifications mentioned are credible. Search the certification name alongside the word 'standard' or 'accreditation'. Credible certifications have publicly available criteria and independent auditing processes. If a brand has invented its own badge, that is worth noting.
What success looks like
After working through these steps, you will have a clear picture of what a brand is willing to show you and what it prefers to leave unexamined. You will not always reach a definitive verdict — sustainability is genuinely complex, and even well-intentioned brands are working through difficult supply chains. But you will be able to distinguish between a report that is trying to inform you and one that is trying to reassure you. That distinction is worth more than any single number.
Publications like Business of Fashion cover brand accountability and industry transparency regularly, and can help you stay current on which brands are being scrutinised and why.
FAQ
How do I find a fashion brand's sustainability report? Scroll to the footer of the brand's website and look for links labelled 'Sustainability', 'Impact', or 'Responsibility'. If nothing appears, search the brand name alongside 'sustainability report' in your browser. Some brands publish PDFs; others use dedicated webpages.
What is the difference between Scope 1, 2, and 3 emissions in a fashion context? Scope 1 covers a brand's direct emissions (its own factories or vehicles). Scope 2 covers the energy it buys. Scope 3 covers everything else — including the farming, spinning, weaving, and sewing done by suppliers. For most fashion brands, Scope 3 is the largest share by far.
How can I tell if a brand is greenwashing? Look for absolute emissions figures rather than ratios, check for third-party verification, and note what the report leaves out. Greenwashing often works through selective reporting rather than false claims — the gaps matter as much as the contents.
What certifications should I look for in a sustainability report? GOTS, bluesign, Fair Trade, and B Corp are awarded by independent bodies with published criteria. Science Based Targets (SBTi) alignment is a credible signal for climate commitments. A brand's own proprietary badge carries less weight.
Do small brands need to publish sustainability reports? Very small independent labels may not have the resources to produce a formal report. For any brand with significant scale and marketing spend on sustainability claims, the absence of structured public data is worth questioning.
