What is it worth to move your materials to preferred production systems?
Almost every brand sourcing cotton, wool or polyester is being asked to move to preferred production systems: certified, traceable, lower-impact supply. The cost of doing that is easy to see, because it arrives as a premium on the fiber bill. The value is not, so the conversation usually stops there.
SHIFT puts a number on the other side of that trade. It is a decision framework and financial model that quantifies, over five years and in your own currency, what the move is worth to a brand your size: the legal and regulatory exposure it reduces, the sourcing costs it takes out, and the revenue it protects.
This page is a teaser. Pick the structure nearest to yours, enter your revenue, and you will have a first read in under a minute. The full platform builds the case on your own portfolio, markets and data.
What SHIFT is, and why we call it that
There is no universal number, because fashion brands run very differently across archetypes and business models. So we built this platform to help brands construct the case on their own data, and get as close as possible to the number that is theirs.
SHIFT stands for Scaling Higher Investment in the Fiber Transition. It is a decision framework, built on a peer-reviewed financial model, that helps brands identify, evaluate, quantify and communicate the financial value of moving their cotton, wool and polyester to preferred production systems.
The name carries two meanings. The first is the shift itself: moving a brand's fibre portfolio from conventional materials to fibres from preferred production systems. The second is a shift in mindset, because shifting fibres without shifting mindsets produces incremental change at best. Shifting both is what turns a sourcing decision into a strategy.
The model behind it was developed by Sustainabelle Advisory Services in connection with the Textile Exchange Preferred Materials Financial Impact Model, through 18 months of research, 34 stakeholder consultations and peer review by two fashion groups and two brands.
Finance, sourcing, design and sustainability share one analytical language and one responsibility, so the case is owned collectively rather than debated departmentally.
Financial impact is more than unit cost: it is the full set of value drivers the transition unlocks and protects, from revenue resilience to regulatory readiness.
The horizon that matters is not the next season or budget cycle, but a multi-year window over which risks compound and benefits accrue.
Your first read
Year by year
Costs are paid early while the largest benefits arrive late, as regulations switch on across the period.
If you charge a price premium
The Base Case holds the premium at zero, because stated willingness to pay rarely survives the shelf. This shows what is at stake in that assumption.
The Information Included on the Platform
The first read runs on one of four reference structures. Members build the case on their own portfolio, challenge every assumption with the function that owns it, and leave with material for each room. The two previews below are drawn from the structure and revenue you chose above.
What moves your number
Ten drivers flexed around your own settings, each with its owner. The widest bar is the assumption to defend first.
What survives the most sceptical reading
The same case with less and less believed: no EU enforcement, no brand equity, then operational lines only.
Your own portfolio
Fibre mix, shares today and 2030 targets by category, sourcing origins, markets and regulations, or a blank start from your own numbers.
Every proxy visible, and ranked
Each of the inputs is marked proxy or your data, and the platform tells you which proxies to replace first for your own result.
Assumptions with owners
Enforcement probabilities for legal, premiums for procurement, reputational risk for marketing, cost of capital for finance.
One case, seven functions
A department report with each function's numbers, the KPIs to track and the graded evidence behind every line, as a branded PDF.
Board-ready exhibits
Twenty-three charts and tables drawn from your inputs, downloadable as images, data or a single Excel workbook.
Built to be co-authored
Save a case and send it to your finance partner, who loads it, edits it and sends it back.
Why not build this yourself?
A capable analyst can build a spreadsheet. What takes years, and what no single brand can see from the inside, is what sits underneath this one.
Evidence no single brand holds
Premiums actually paid by peer brands, the view from producers, traders and innovators, and real enforcement experience, gathered in 34 consultations and then averaged and anonymised. It is pre-competitive data you cannot collect about your own competitors.
A number that is not only yours
In our interviews, cases presented to finance as finished products were dismantled. This model was stress-tested with live data by two fashion groups and two brands, so it arrives with a standing your own spreadsheet does not have.
Conservative by construction
Around 140 assumptions, each sourced, graded and open to challenge. Peer review pushed every one toward its cautious end and kept demonstrated value strictly apart from speculative value.
The regulatory mapping is done
Six regulations translated into exposure, timing and cost, and eight certification standards scored for the protection each provides against them, by supply chain tier and by sourcing origin.
A first case today, not next year
The data gaps behind a first credible case can take a year or more to close. Research proxies let you start now, and the platform shows exactly which inputs to collect first.
Built to be used in the room
One case translated for seven functions, with the exhibits ready for a board paper. Your data stays in your browser and the conclusions stay yours.
The five SHIFT steps
The platform follows the same order as the framework.
- Luxury, Pure Fashion, Sportswear, Mass Market, or your own numbers
- Finance co-authors; legal, procurement and marketing each own their assumptions
- A reader can discount any layer without sinking the rest
- Every driver tested with its owner before leadership sees the case
- Which fibre first, which production system, which suppliers, and when
How the number is built
The model compares a transition to a higher share of preferred materials against no further action, from 2026 to 2030. Only the increment between your share today and your 2030 target drives the result.
Risk
Fines, market bans, border detentions, legal and reputational cost, supply disruption from climate and other shocks, and reputational events.
Opportunity
Traceability efficiencies, compliance execution savings, EPR bonuses, and, only when you switch them on, price premium and demand uplift.
Investment
Material premium on the incremental volume, program fees for direct sourcing, supplier integration, and material and quality testing.
The SHIFT Base Case is a conservative floor: no price premium, no demand uplift, no value for the certified base a brand already holds, and every probability at its cautious setting. The SHIFT Upside Case applies a 1 percent price premium, a 1.7 percent demand uplift and the regulatory drivers at their favourable end. It is a tested range, not a forecast. Most modelled value is avoided loss rather than new revenue, so for most brands the case is best framed in the language of insurance.
Limits, stated plainly: the model sees one brand acting alone, assumes preferred material is available in full, holds prices and premiums flat to 2030, and treats enforcement that is still unsettled as forward-looking estimates.
