Fair Trade vs. B Corp vs. GOTS: Ethical Knitwear Certifications Compared
A jumper can carry three different certifications and still leave you with questions. GOTS tells you about the fibre and how it was processed. Fair trade tells you about the deal the cotton farmer got, or the terms the sewing floor worked under. B Corp tells you about the company as a whole. These are not competing stamps. They answer different questions, and shopping gets much easier once you know which question you are asking.
Here is what each one covers, what it quietly leaves out, and how to combine them on a real purchase.
Work out your question first
Certifications are answers, so start with the question. Most knitwear concerns fall into four buckets: the fibre (organic cotton, wool from a farm with animal welfare standards), the processing (dyes, wastewater, chemical residues), the people (were workers paid and treated decently), and the company (does it behave like a business that takes responsibility for its supply chain).
No single label covers all four. Match the label to the thing you care about most.
GOTS: the fibre and the factory floor
The Global Organic Textile Standard is the most demanding of the three at product level because it follows the material from the field to the finished garment. Organic fibre content is the entry point: a garment labelled "organic" must be at least 95% organic fibre, while "made with organic" allows 70%. From there, every processing stage — spinning, knitting, dyeing, cutting, sewing — has to be certified.
Environmental criteria cover a restricted substances list, wastewater treatment and chlorine-free bleaching. Social criteria based on the core ILO conventions apply to processing and manufacturing sites. Because each stage is certified, the finished jumper should come with a licence number you can check in the public GOTS database. Worth doing: that number is the difference between a certified supply chain and a nice-looking label.
What GOTS doesn't do
It doesn't require wages above the legal minimum where the factory operates, and it doesn't assess the brand's own operations, transport emissions or how long the jumper will last. Animal welfare reaches a GOTS wool jumper only through the organic farming standard behind the fibre, so if the farm matters to you, look for a wool-specific standard as well.
Fair trade: the price, the premium, the people
Fair trade certifications focus on trading relationships rather than materials. On the farm side, the familiar mark on cotton guarantees a minimum price, a premium paid to the producer organisation, democratic structures and rules against child and forced labour. The premium is spent collectively — a co-operative might vote for new equipment, training or a school bus.
Some schemes certify factories instead of farms. Workers then receive a premium and elect a committee to decide how it is used, and the standard includes provisions intended to move wages toward a living wage over time. Coverage varies a lot by scheme and region, and programmes change, so check what the specific mark on your label currently applies to. WFTO takes a third route: it certifies whole businesses against fair trade principles rather than individual products.
The blind spot is materials. Fair trade cotton is not automatically organic, and a fair trade mark says nothing about dye chemistry or chemical residues in the finished knit. It also says little about the brand's environmental footprint.
B Corp: the whole company, not the jumper
B Corp is a company-level certification from B Lab. A business has to score at least 80 points on the B Impact Assessment, which looks at governance, workers, community, environment and customers; change its legal documents to make accountability to stakeholders binding; and recertify every three years. Scores are published, so you can compare one brand against another.
The catch is that it certifies nothing about a specific garment. A B Corp can sell a conventional acrylic jumper. What you are getting is evidence that the company's policies on employee pay, energy use, supply chain oversight and governance were assessed — largely through self-reported answers backed by documentation, with verification and site reviews for larger companies. That is genuinely useful, and it is a different kind of useful from a fibre standard.
What none of them cover
Whichever label you buy, some things stay invisible:
- Durability — whether the jumper pills, loses shape or survives twenty washes
- Overproduction — how many units were made versus sold, and where the surplus went
- Transport, including air freight
- Design choices that make a garment hard to repair or recycle
- Retail, packaging and end of life
- Whether the brand's marketing is honest about the limits of its certificates
A certification is a floor, not a ceiling. A brand can meet a standard and still be a business you would rather not support.
