The evidence on green premiums in B2B textile sourcing is thin and points to costs falling on suppliers. Here is what I could confirm, what I could not, and where a supplier's data does have a price.
Does a supplier earn a higher price for lower emissions, certified materials or better data? The honest answer from the evidence I could find is: not reliably, and the cost of meeting brands' requirements often falls on the supplier. There is little hard data on B2B premiums, so this article sets out what is documented and marks where I cannot back a claim. The earlier version quoted a specific supplier survey figure that I could not verify, and it said CBAM covers textiles, which is wrong, so I removed both.
| Finding | Source | What it means |
|---|---|---|
| Only 6 of 42 fashion brands reported offering project financing for suppliers' decarbonisation. About half offered some support, mostly assessments, audits or small pilots | Stand.earth fashion scorecard, 2025 (via Thomson Reuters Foundation, 30 June 2025) | Brands set targets, but few fund the supplier changes behind them. Stand.earth is an advocacy group |
| 63% of suppliers say brands expect them to advance sustainability while continuing to squeeze margins | Vogue Business survey, quoted on a Better Buying webinar page | Cost pressure is common; I could not see the survey method or sample |
| Between 1% and 7% of consumers had paid a premium for sustainable products | BCG survey of 19,000 consumers in eight countries, 2022 | Consumer demand for a premium is limited. It is not a B2B measure |
None of these directly measures how many B2B buyers pay a price premium. The original version of this article quoted the Better Buying Partnership as showing that fewer than 20% of suppliers received compensation for sustainability requirements in 2022 to 2025. I could not find that figure. Better Buying is now run under Cascale, and I could not read its 2025 findings, so I do not repeat any number from it.
A brand's sustainability team sets commitments, while sourcing teams are judged on cost per unit. Unless there is a mechanism that turns a commitment into purchase terms, such as a price premium, preferred supplier status or financing, the requirement can arrive without any payment attached. This is a reasoned account of how procurement is organised. I do not have measured data on how often it happens.
Three situations in which a supplier's sustainability work has a price or a clear commercial value:
Where it shows up
On CBAM, the original said that some textiles and leatherwear are covered. They are not. The covered goods are iron and steel, aluminium, cement, fertilisers, electricity and hydrogen, so for a textile supplier the CBAM route is indirect at most. For a textile or leather supplier, the practical value of measured data is that customers and the CSRD ask for it, not that CBAM taxes the product.
On SBTi, the original said that brands are "contractually committed" to improving supply chain intensity. A validated target is the brand's own public commitment, not a contract with suppliers. The original also said that this influences preferred supplier programmes at several major brands, and I found no source for that, so it is out.
I would not invest in sustainability mainly to win a premium, because the evidence for one is weak. Invest where the saving is yours: energy efficiency that lowers your own bills, and measured emissions data that customers increasingly ask for. Where a customer wants you to do more, ask what it will pay or finance, and get the answer in writing.
If a customer asks for a certification or a data system, ask four questions: what volume will it commit, for how long, what price or financing will it provide, and what happens if you do not comply. If it will not answer, treat the request as a cost you carry.
Steps
I could not find solid data that they usually do. What I found points to costs falling on suppliers: the 2025 Stand.earth scorecard found only 6 of 42 brands reporting project financing for supplier decarbonisation.
No. It covers iron and steel, aluminium, cement, fertilisers, electricity and hydrogen. Check the covered list before assuming that a product is in or out.
I could not find a reliable figure. The earlier figure of under 20% could not be verified.
A 2022 BCG survey found that 1–7% of consumers had paid a premium. That measures consumers, not business buyers.

Most brands estimate purchased-goods emissions from spend and averages. What that does to the numbers, what the CSRD and SBTi actually require, and what a supplier can provide.
Textiles are not covered by the EU Carbon Border Adjustment Mechanism, and they are not in the Commission's current extension proposal. This guide explains what CBAM does cover, how its costs are calculated, and what a Pakistani textile manufacturer should prepare.
