How to reduce emissions in the fashion industry by acting on Tier 2 production
A practical guide for brands, manufacturers and suppliers that want to decarbonize the textile supply chain through operational criteria, primary data and real collaboration.
Reducing emissions in the fashion industry requires action in one of the areas where much of the climate impact is concentrated: Tier 2 production. This is the stage where materials are converted into fabric and processed before garment manufacturing. It can account for a significant share of a clothing company’s Scope 3 emissions, which means that focusing only on low-impact materials or recycling campaigns is not enough. Brands need primary data, better supplier selection and investment strategies that improve energy efficiency, renewable energy use and emissions reduction at source.
Why are fashion industry emissions a priority?
Fashion industry emissions are a priority because much of the sector’s environmental impact comes from high resource intensity and high energy demand during textile production. If the industry wants to meet climate targets, it must reduce emissions across the supply chain with more precision and depth.
Although many visible initiatives focus on recycled garments, greener packaging or consumer-facing sustainability campaigns, the strongest opportunities for improvement are often deeper in the supply chain.
Reducing emissions in fashion requires action where the highest energy consumption takes place, not only where the change is most visible for marketing.
What role do Tier 2 suppliers play in a brand’s carbon footprint?
Tier 2 suppliers play a key role because they manage processes such as dyeing, washing and finishing fabrics. These stages can represent a major part of Scope 3 emissions and often remain outside the direct visibility of many brands.
Many brands work primarily with Tier 1 suppliers, which are responsible for final garment manufacturing. However, the production and treatment of fabrics happen earlier, and that is where many emissions are generated.
High-impact processes
Fabric treatment involves energy, water and industrial processes that increase the environmental footprint of each garment before final manufacturing.
Limited visibility
Many brands do not work deeply enough with Tier 2 suppliers, even though this is where decisive decarbonization opportunities are often found.
Textile decarbonization does not depend only on product design. It also depends on how the fabric is produced and which supplier produces it.
Why can acting on Tier 2 suppliers be an efficient way to reduce emissions?
Acting on Tier 2 suppliers can be efficient because it targets a stage where sustainable technologies already exist and can deliver real improvements. Many of these measures can be implemented without making production costs unmanageable.
The challenge is not only identifying solutions. It is also helping suppliers implement them in contexts where renewable infrastructure, financing and technical knowledge may be limited.
- Many suppliers operate in countries with limited renewable energy infrastructure.
- Access to financing for sustainability projects is often complex.
- Technical knowledge about energy planning may not always be available.
- Cost pressure can delay investments with medium-term returns.
Which strategies can decarbonize textile production more effectively?
The two most effective strategies are sustainable technology investments by suppliers and strategic supplier selection by brands. Combining both approaches allows the industry to move faster and with more consistency.
Real decarbonization rarely depends on a single action. It requires coordination between operational, financial and sourcing decisions.
| Strategy | What it provides | Operational impact |
|---|---|---|
| Sustainable technology investment | Improves energy efficiency and reduces emissions at source. | Drives structural change in Tier 2 production. |
| Strategic supplier selection | Integrates carbon footprint into sourcing decisions. | Redirects volume toward partners with better environmental performance. |
| Combination of both routes | Connects investment, traceability and sourcing. | Accelerates a more realistic and scalable transformation. |
How can brands support climate action through their supply chains?
Brands can support climate action when they stop limiting themselves to demanding improvements and start offering real support to suppliers. Collaboration is a practical condition for reducing emissions at scale.
When brands participate in financing, technical knowledge or shared projects, suppliers have more options to adopt long-lasting sustainable improvements.
- Create investment partnerships for renewable energy in producing countries.
- Facilitate access to financing with favourable conditions for environmental upgrades.
- Share best practices and energy planning tools.
- Coordinate with other brands that use the same production base.
Sustainability in fashion moves faster when brands turn supplier collaboration into an operational strategy, not an isolated requirement.
How should brands measure and plan carbon footprint reduction in fashion?
Measuring carbon footprint in fashion properly requires working with primary data from each supplier, not only with industry averages. Generic data can lead to incomplete diagnoses and poorly prioritized investments.
A useful planning tool is the Marginal Abatement Cost Curve, or MACC. It helps visualize which actions can reduce the most emissions with the most favourable relationship between cost and impact.
Why is primary data more useful than industry averages?
Primary data reflects the real operational situation of each supplier. It helps identify which facilities emit more, where improvement opportunities are located and which measures should be prioritized.
What does a MACC add to decision-making?
A Marginal Abatement Cost Curve helps rank actions according to cost and reduction capacity. This allows brands to build a more realistic and better-sequenced action plan.
What is the value of combining MACCs with traceability?
Combining economic analysis and traceability makes it possible to create a clearer roadmap for each production stage, with evidence-based decisions and more precise follow-up.
Which concrete actions help reduce fashion industry emissions?
The most useful actions are those that improve relationships with Tier 2 suppliers, raise data quality and enable sustainable investments. Reducing emissions requires a mix of control, collaboration and planning.
The most effective measures do not only reduce environmental impact. They can also improve energy efficiency, optimize processes and strengthen supply chain resilience.
- Establish long-term relationships with Tier 2 suppliers.
- Gather and use primary emissions data to make better decisions.
- Train and incentivize suppliers with plans and best practices.
- Facilitate access to sustainable financing for decarbonization projects.
- Invest in renewable energy at source through agreements or certificates.
- Collaborate between brands that share common supply chains.
Why is this transformation also an opportunity to rethink the supply chain?
This transformation is an opportunity because it forces brands to review how suppliers are selected, how impact is measured and how sustainability and efficiency are integrated into the business. The carbon footprint reflects structural decisions, not only environmental ones.
Brands that act early can gain resilience, reputation and operational capability, while moving toward textile production that is more aligned with climate goals.
Reducing emissions in fashion is not only an environmental challenge. It is also an opportunity to build supply chains that are stronger, more measurable and better prepared for the future.
Frequently asked questions
What does Tier 2 mean in the fashion industry?
Tier 2 refers to the supply chain stage where fabrics are produced and treated before garment manufacturing. It includes processes such as dyeing, washing and finishing, and often represents a significant part of Scope 3 emissions.
Why can reducing emissions in Tier 2 have such a strong impact?
Because this stage includes industrial processes with high energy consumption and a large weight in the sector’s climate footprint. Acting on Tier 2 targets one of the areas with the greatest structural reduction potential.
What role should brands play in supporting decarbonization?
Brands should go beyond demanding results and provide real support through financing, collaboration, best-practice sharing and supplier selection criteria that include carbon footprint. Without this support, many improvements are harder to implement.
Why is primary emissions data important?
Primary data shows the real situation of each supplier and supports more precise decisions. Using only industry averages can hide important differences and lead to less effective reduction plans.
What is a Marginal Abatement Cost Curve?
It is a tool that compares emissions reduction actions according to their cost and potential impact. It helps prioritize feasible measures and build a clearer decarbonization plan.
Can emissions reduction also improve operational efficiency?
Yes. Many actions that reduce emissions also improve energy efficiency, optimize processes and strengthen supply chain stability. Sustainability and operational performance can move forward together.
