Over the past few years, regenerative cotton has moved rapidly up the agenda for the fashion industry. Several brands have made public commitments to sourcing it, driven by climate targets, biodiversity ambitions and an evolving regulatory landscape. At the same time, new certifications, sourcing pathways and programmes are making regenerative cotton increasingly available.

To better understand these market dynamics, Milkywire partnered with Vere Initiatives, a philanthropy focused on conservation and agricultural resilience, to carry out research across the regenerative cotton value chain. The research combined desk research with interviews across brands, standards organisations, programme developers, manufacturers and independent experts. The aim was to understand how the regenerative cotton market is evolving, how regenerative cotton reaches brands and what is shaping its direction.

One point became clear. Regenerative cotton is often discussed as though it were a single category, but the market is developing through different sourcing pathways with different objectives, evidence requirements and commercial models.

Understanding those differences is important. But brands should not begin by asking which certification is best. A more useful starting point is to ask what they want to achieve through regenerative cotton.

What regenerative cotton means in practice

Regenerative agriculture does not have one globally agreed definition. Its principles are intended to be adapted to different landscapes, farming systems and environmental conditions. This flexibility allows farmers and programmes to respond to local needs, but it has also led to different interpretations of what should qualify as regenerative.

One important distinction is between practice-based and outcome-based approaches.

Practice-based approaches assess what farmers are doing. This may include adopting cover crops, reducing synthetic inputs, changing tillage practices or introducing measures intended to improve soil health and biodiversity.

Outcome-based approaches focus more on what has changed. They seek to measure environmental outcomes over time, such as changes in soil health, biodiversity or water quality.

In reality, most programmes sit somewhere along this spectrum. Some are primarily focused on helping more farmers begin adopting regenerative practices. Others combine practice requirements with greater investment in traceability, data collection and the measurement of environmental outcomes.

These approaches involve different trade-offs. Practice-based approaches can enable wider participation and may be easier to integrate into existing supply chains. Outcome-based approaches often require more investment, stronger traceability and longer-term partnerships. However, they can also generate the evidence brands may increasingly need to substantiate environmental claims as regulation and market expectations evolve.

This does not mean practice-based approaches are failing to do what they were designed to do. It means that practice adoption and verified environmental outcomes are not the same thing. 

How brands can engage with regenerative cotton today

One question came up repeatedly throughout the research: how can brands actually engage with the regenerative cotton market? We found three broad pathways.

1. Purchasing certified regenerative cotton already available on the market

The most accessible route is to purchase regenerative cotton that has already been certified and is available through existing supply chains.

This allows brands to begin sourcing regenerative cotton without creating a new programme, changing established supplier relationships or making a significant long-term commitment. It has played an important role in expanding the market and making certified cotton easier to access.

However, brands should not assume that purchasing certified cotton automatically provides a clear connection to the farm where it was grown.

Cotton is commonly aggregated during ginning and later stages of the supply chain. Fibre from different farms may be brought together before it reaches the spinner, mill or brand. Preserving the identity of certified cotton therefore requires additional systems, oversight and coordination.

Maintaining these systems costs money. Where premiums are very low, an important question arises about how much investment is available for farmer support, segregation, traceability and programme implementation.

This route remains a useful entry point. But it may not meet the needs of brands seeking farm-level visibility, closer relationships with producers or evidence of measured environmental outcomes.

2. Joining an established regenerative programme

A second route is to join a programme that has already developed farmer relationships, implementation systems and supply chain partnerships.

Rather than buying certified supply through the open market, the brand enters a longer-term relationship with an organisation that is actively managing how the cotton is produced and moves through the supply chain.

These programmes can provide greater visibility into farmer support, practice adoption and traceability. Some also include additional monitoring and measurement to generate evidence of environmental outcomes.

This route generally requires larger volume commitments, longer collaboration and higher premiums. The brand is not only paying for cotton and certification. It is helping fund the infrastructure required to run the programme and demonstrate what it is delivering.

3. Investing in future regenerative supply

A third route is to invest directly in developing new regenerative cotton supply.

This often begins before the cotton is commercially available. Funding may support farmer training, technical assistance, data collection, certification and the early costs of transitioning farming systems.

For some brands, this is primarily an investment in the wider market. For others, it is intended to create a future sourcing pathway connected more closely to their own supply chain.

This approach offers brands a greater opportunity to shape how the programme is developed. It also comes with more risk. Investing in farmers and programme development does not automatically guarantee that the resulting cotton can be integrated into a brand’s existing supply chain.

These three routes are not simply different sourcing options. They represent different levels of involvement in building the regenerative cotton market.

Three challenges shaping the market

1. Premiums are being asked to fund very different things

Brands often compare regenerative cotton sourcing options on price without first considering what the premium is paying for.

In one model, the premium may primarily cover certification and supply chain administration. In another, it may also fund farmer payments, technical support, traceability, environmental monitoring and the collection of data over several seasons.

These are fundamentally different value propositions.

Supporting farmers, running a credible programme and proving environmental outcomes all require investment. Some of those costs may fall as farmers progress through the transition. Others, particularly measurement, reporting and verification, remain necessary for as long as outcome claims are being made.

A low premium is therefore unlikely to simply reflect a lower price for the same product. It may reflect a different programme, a different level of evidence and a different allocation of cost.

2. Purchasing decisions shape market outcomes

One of the clearest messages from the research was that markets respond to demand signals.

Many brands have ambitious regenerative cotton targets, but those ambitions are not always reflected in purchasing decisions. Short buying cycles, uncertain demand and continued pressure on cost make it difficult for suppliers and programme developers to invest with confidence. Without clear signals that brands will continue purchasing regenerative cotton over the long term, there is less incentive to invest in building new supply, strengthening traceability systems or supporting farmers through the transition to regenerative agriculture.

This also shapes which sourcing pathways continue to grow. If demand is primarily for certified regenerative cotton that is readily available through existing supply chains, investment is likely to continue flowing towards pathways designed for accessibility and scale. By contrast, established programmes and investments in future regenerative supply may rely on stronger traceability, closer farmer engagement or measurement of environmental outcomes. These pathways require a different type of demand signal, one that gives organisations the confidence to invest over time.

In other words, purchasing decisions do not just influence what is available today. They influence what the market invests in, what scales and ultimately what the future regenerative cotton market looks like.

3. Financing the transition remains an unresolved market challenge

Regenerative agriculture is built around long-term change. Farmers often need several seasons to adopt new practices, manage risk and begin seeing measurable environmental and economic benefits.

The challenge is that the market has not yet established a consistent way of financing that transition.

Across the research, different pathways relied on different funding mechanisms. Some were supported through brand premiums, others through philanthropy or programme funding. While these approaches have enabled important projects to develop, they remain fragmented and are often dependent on a small number of committed partners.

As demand for regenerative cotton grows, this question becomes increasingly important. If brands expect more farmers to transition, greater traceability and stronger evidence of environmental outcomes, the market will also need more consistent ways of financing those activities at scale.

How that transition is financed will therefore be critical to scaling regenerative agriculture.

The market is scaling, but towards what?

The research suggests that the challenge facing the regenerative cotton market is no longer simply whether it will grow, but how it will grow. Different sourcing pathways prioritise different things, from accessibility and scale to stronger traceability, farmer engagement and evidence of environmental outcomes.

Ultimately, regenerative cotton is not just a sourcing decision. It is a market-building decision.

For brands navigating this landscape, choosing a programme is only part of the decision. These are the questions to start with:

• What outcomes are we trying to achieve?

• What level of traceability and evidence will we need?

• What are we expecting the premium to fund?

• Are our purchasing decisions creating the demand signals needed to build the market we want to see?
