Who Pays for the Decarbonization of the Fashion Industry?

Fashion brands and suppliers face a trillion-pound funding shortfall

The fashion industry knows how to cut emissions. What it has not resolved is who pays for the transition. Brands increasingly expect suppliers to reduce carbon footprints, yet the cost of cleaner energy, updated machinery, and low-carbon production upgrades typically falls on manufacturers rather than the retailers who set purchasing terms. This creates a structural problem: the factories that generate most emissions often have the least access to affordable capital.

Estimates suggest decarbonizing fashion supply chains will require just over one trillion dollars in investment. That figure, from Aii and Fashion for Good, highlights the scale of the funding gap. Meanwhile, McKinsey analysis indicates most fashion brands could cut over 60 per cent of their greenhouse gas emissions for less than two per cent of revenues. Despite this, many remain behind schedule on reduction targets. Some have even seen emissions rise after making public commitments.

The question facing UK businesses that source from garment manufacturers is not whether decarbonization is technically feasible. It is whether the financing model supports it. For SMEs that rely on fashion supply chains, this matters commercially. Procurement decisions increasingly include carbon criteria, and suppliers unable to fund emissions cuts may lose competitiveness in tenders or face delisting by major buyers.

New shared-finance model shifts risk from suppliers to brands

Several large fashion retailers are testing a different approach. H&M Group, Bestseller, Gap Inc., and Mango have backed the Future Supplier Initiative, which aims to lower borrowing costs for manufacturers by having brands underwrite supplier debt. The mechanism works through either full collateralization of loans or partial guarantees, allowing banks to offer more competitive interest rates to factories that would otherwise face high costs or no credit access at all.

The program launched initially in Bangladesh, with plans to expand into Vietnam, India, China, Italy, and Türkiye. These countries host significant garment production capacity, and many suppliers there lack affordable finance for capital-intensive upgrades such as solar installations, energy-efficient dyeing systems, or wastewater treatment improvements. By backing loans, brands effectively transfer creditworthiness down the supply chain, reducing the financial barrier for suppliers to act.

This marks a shift from the traditional model, where brands negotiate prices downward while expecting suppliers to absorb investment risk independently. Under the new structure, brands accept some liability in exchange for suppliers meeting decarbonization milestones. The arrangement creates shared accountability, though it also introduces new reporting and verification requirements for both parties.

Upstream emissions drive most of fashion’s carbon footprint

Fashion supply chains are emissions-intensive by design. A large share of climate impact occurs upstream, particularly in fabric production, dyeing, wet processing, and energy use at manufacturing sites. Because brands typically outsource these activities, they control purchasing decisions but do not own the assets that generate emissions. This creates a split between responsibility and investment capacity.

Suppliers operate on thin margins, often between two and five per cent. Consequently, capital expenditure on emissions reduction competes directly with working capital, wages, and maintenance budgets. For smaller manufacturers, the choice is stark: invest in decarbonization and risk cash flow problems, or wait for cheaper technology and risk losing contracts. This dynamic explains why adoption of low-carbon solutions remains uneven despite technical availability.

Moreover, suppliers in developing economies face higher borrowing costs than brands headquartered in Europe or North America. A garment factory in Bangladesh might pay 10 to 15 per cent interest on a commercial loan, while a UK retailer can access debt at a fraction of that rate. Consequently, the same solar panel installation costs more in real terms for the supplier than it would for the brand, even though the supplier has less revenue to cover it.

The financing imbalance also affects speed of transition. Brands set decarbonization targets aligned with their own timelines, but suppliers need predictable, long-term purchase commitments to justify capital investments. Short contract cycles and volatile order volumes make it difficult for factories to secure loans or plan upgrades. Without financial backing from buyers, many suppliers delay action until regulatory pressure or lost business forces their hand.

How financing structures affect UK sourcing and compliance

UK businesses that source clothing or textiles face increasing scrutiny over supply chain emissions. Public sector procurement rules now include carbon reduction criteria, and private sector clients often require suppliers to demonstrate environmental performance. For SMEs that manufacture or trade fashion products, this means upstream emissions are becoming a direct commercial risk.

If your suppliers cannot afford decarbonization, several consequences follow. First, you may struggle to meet your own Scope 3 emissions targets, which include purchased goods and services. Second, you risk exclusion from tenders that require verified supply chain carbon data. Third, you face potential cost increases if suppliers pass financing costs onto unit prices without improving efficiency.

Conversely, suppliers that secure affordable finance for emissions cuts can often reduce operating costs over time. Solar power lowers electricity bills, efficient boilers cut fuel use, and waste heat recovery reduces energy demand. These savings improve competitiveness, but only if upfront capital is available. Therefore, brands that help suppliers access finance may benefit from lower costs and more stable supply relationships in the medium term.

For UK businesses, this creates both risk and opportunity. Companies that support supplier decarbonization early may secure better pricing and contract terms as carbon regulations tighten. Those that wait may find themselves reliant on suppliers unable to meet future compliance requirements, forcing costly last-minute switches or price renegotiations. Additionally, businesses that can demonstrate funded supplier improvements gain an advantage in ESG reporting and client due diligence processes.

The regulatory context is also shifting. The UK government has signaled that supply chain emissions reporting will become more detailed, and the EU is implementing supply chain due diligence rules that affect UK exporters. Consequently, businesses need visibility into supplier carbon performance, and suppliers need funding to deliver it. This alignment of commercial and regulatory pressure makes financing models a central issue, not a secondary concern.

Five financing barriers suppliers face in reducing emissions

• High interest rates on commercial loans in manufacturing countries often exceed 10 per cent annually, making payback periods for energy upgrades prohibitively long compared to typical contract durations with buyers.
• Lack of collateral prevents smaller suppliers from accessing bank credit, as many do not own factory buildings or have sufficient fixed assets to secure loans for capital expenditure.
• Short purchasing cycles from brands create uncertainty, so suppliers cannot commit to multi-year loan repayments without guaranteed order volumes that justify the investment.
• Limited technical capacity means many suppliers lack in-house expertise to assess decarbonization options, prepare funding applications, or manage installation projects, increasing perceived risk for lenders.
• Currency risk affects suppliers in developing economies who must repay foreign-currency loans while earning revenue in local currency, exposing them to exchange rate volatility that brands do not share.

What industry experts recommend for shared investment

Industry analysts broadly agree that brands need to move beyond asking suppliers to decarbonize at their own expense. Trellis, a supply chain advisory group, outlines four priorities for brands: provide direct financial support, back first-mover projects, collaborate on technical solutions, and share both risk and cost with suppliers. This approach treats decarbonization as a joint investment rather than a purchasing condition.

Direct financial support includes mechanisms like the Future Supplier Initiative, but can also involve subsidized loans, grants for feasibility studies, or co-investment in specific equipment. For example, a brand might cover half the cost of a solar installation in exchange for verified emissions reductions over a set period. This spreads risk and accelerates action, particularly for suppliers who cannot wait for equipment to pay back through energy savings alone.

Backing first-mover projects is important because early adopters of low-carbon technology face higher costs and greater uncertainty. Brands that guarantee purchase volumes or premium prices for decarbonized products give suppliers confidence to invest ahead of competitors. Over time, this drives down costs for later adopters and creates market pull for green technology. However, it requires brands to accept higher short-term costs in exchange for long-term supply chain resilience.

Technical collaboration addresses another barrier. Many suppliers lack the expertise to evaluate energy audits, compare technology options, or negotiate with equipment vendors. Brands with sustainability teams can provide this knowledge, either directly or by funding third-party advisors. Similarly, sharing best practices across supplier networks helps smaller manufacturers learn from peers who have already completed upgrades. This reduces duplication of effort and lowers overall industry costs.

Sharing risk and cost means rethinking contract structures. Longer-term agreements give suppliers the stability to repay loans, while price adjustments that reflect decarbonization investment acknowledge the real cost of transition. Some brands are experimenting with carbon-linked pricing, where unit costs include a premium for verified emissions reductions. This makes the cost of decarbonization visible and distributes it across the value chain rather than concentrating it at the factory gate.

For UK businesses, these recommendations translate into practical steps. Review supplier contracts to identify whether terms support or hinder investment in emissions cuts. Consider whether your purchasing volumes and payment terms give suppliers confidence to borrow for upgrades. Assess whether you have technical resources to share, or whether you need to partner with advisors who can support your supply chain. Finally, evaluate whether your pricing structure allows suppliers to recover decarbonization costs without eroding margins that fund future investment.

Where to find guidance on supply chain decarbonization funding

The UK government provides resources on supply chain emissions through the Department for Energy Security and Net Zero, including guidance on net zero strategy and supply chain considerations. For businesses looking at carbon reporting and Scope 3 compliance, structured support can help navigate both measurement and financing questions.

The Institute of Environmental Management and Assessment offers industry-specific guidance on Scope 3 emissions and supply chain engagement, including practical case studies from manufacturing sectors. Meanwhile, the Chartered Institute of Procurement and Supply provides sustainable procurement frameworks that address financing and contract structures for environmental performance.

Fashion industry bodies such as the British Fashion Council publish updates on sustainability initiatives and financing mechanisms, relevant for businesses across the textile supply chain. Additionally, businesses can explore sustainable procurement support tailored to managing supply chain carbon and compliance requirements.
