Sustainability reporting in fashion is entering a new phase—one that demands more than surface-level metrics and glossy commitments. At the centre of this shift is double materiality: a framework that enables businesses to evaluate how sustainability risks are impacting their bottom line, and also how their operations are affecting people and the planet.
What began as a concept in niche ESG circles is now a regulatory requirement under the EU’s Corporate Sustainability Reporting Directive (CSRD). For smart businesses, double materiality is about more than compliance. This framework equips them to successfully navigate complex supply chains, volatile sourcing risks, and rising stakeholder scrutiny.
Double materiality offers a clearer lens for strategic decision-making, risk management, and long-term value creation.
Today, we will unpack for you what the practice of double materiality looks like for fashion brands and manufacturers. We will discuss fashion-specific examples, a step-by-step assessment process, and get some clarity on the broader relationship between Double Materiality and other regulations like CSRD, ESPR, and other ESG expectations.
What Is Double Materiality Through A Fashion Industry Lens
Double materiality asks fashion businesses to do something radical: stop thinking about sustainability as someone else’s problem.
At its core, it’s a framework that asks businesses to evaluate sustainability from two angles:
- Financial materiality: How environmental and social issues affect your business.
- Impact materiality: How your business affects people and the planet.
Together, they offer a 360° view of risk, opportunity, and responsibility.
For fashion businesses, Double materiality is becoming a legal obligation more and more every day. With the CSRD and global investor pressure, raising accountability is becoming central to how the industry defines success.
1. Financial Materiality: The Outside-In Lens
This is familiar territory for most CFOs and investors. It’s about identifying sustainability and social issues that could affect your bottom line.
- Climate risk: How will rising temperatures or water scarcity impact cotton sourcing, prices or dye house operations?
- Regulatory pressure: Will carbon taxes or extended producer responsibility laws increase operational and logistics costs?
- Reputation: How do issues like worker exploitation or overproduction influence brand value and investor trust?
The key question you will notice is: “Could this issue affect our enterprise value, reputation, or cost of capital?”
2. Impact Materiality: The Inside-Out Lens
This is where the fashion industry has historically fallen short. Impact materiality flips the lens and asks, How is your business affecting sustainability and the world at large? Are they negatively or positively affecting people, ecosystems and economies?
The central question here for fashion businesses is:
- Are we underpaying garment workers across our supply chain?
- Are our dyeing and washing processes polluting local water sources?
- Are we fuelling deforestation by sourcing viscose or leather from unknown origins?
- How much GHG emissions are we generating through our supply chains, i.e Scope 3?
Even if issues like these are not listed in your P&L, YET!
The hard truth is they are essential under regulation like CSRD, which makes assessment and reporting of your sustainability impact MANDATORY.
Fashion sits at the intersection of global trade, resource extraction, and cultural influence. It is both vulnerable to environmental risk and responsible for significant social and environmental impacts. Double materiality forces companies to see both sides of this equation and respond accordingly.
It’s not just about what’s financially relevant now. It’s about identifying what’s socially and environmentally significant today, because that’s what will shape financial risk tomorrow.
Double vs Dual Materiality: Are They the Same?
If you’ve been digging through various sustainability disclosures, you’ve likely come across the terms: double materiality and dual materiality. Are they the same?
In practice, yes. But depending on your audience and context, the answer becomes more nuanced.
So why the semantic split?
“Dual materiality” is the official term used in the European Sustainability Reporting Standards (ESRS), the technical backbone of the CSRD. If you’re preparing disclosures for an EU audience or working with ESRS templates, that’s the language you’ll see and use.
“Double materiality”, on the other hand, is the more popular term used by people in industry. It’s the term that’s made its way into mainstream sustainability reporting, annual reports, and boardroom agendas.
So basically, it’s a linguistic difference, not conceptual.
But for fashion and textile businesses navigating cross-border operations and evolving ESG regulations, choosing the right terminology in the right context signals credibility. Use “dual materiality” in your CSRD-aligned official reports. Use “double materiality” when explaining your sustainability strategy to broader audiences like leadership and consumers.
What is the difference between Single and Double Materiality?
For a long time, fashion brands have been telling only half the story. Under traditional financial reporting, companies were expected to disclose what sustainability risks might cost them, not what they might be costing the planet or the people making their clothes.
That’s single materiality in a nutshell: a one-way lens that looks at how environmental and social issues might impact a company’s bottom line. But in a sector that’s intrinsically tied to overproduction, water scarcity, carbon emissions, and labour inequality, that narrow framing no longer holds up.
This is where double materiality comes in; it pushes fashion businesses to consider both sides. To keep one eye on how climate change, regulation, and social unrest could threaten their financial future. The other on how their decisions, from fibre sourcing, logistics mix to wage policies, actively shape those very challenges.
Let’s understand this better with this table:
| Dimension | Single Materiality | Double Materiality |
| Core Perspective | Outside-in (financial impact on the business) | Outside-in and inside-out (financial + societal/environmental impact) |
| Primary Audience | Investors, shareholders | Investors, regulators, consumers, civil society |
| Disclosure Focus | Risks to company value | Risks and impacts caused by company activities |
| Regulatory Example | Traditional financial reporting (e.g., IFRS) | CSRD / ESRS, GRI, and other ESG frameworks |
| Fashion Example | Higher costs due to polyester tariffs | Brand’s contribution to fossil fuel demand via polyester dependence |
Single materiality gives fashion companies an exit route. It lets them talk about how climate change is disrupting their supply chain without acknowledging the human rights abuses happening in their supply chain. Brands will talk about a price increase due to raw material shortage, but ignore the FLAG emissions associated with those raw materials.
That’s not transparency, that’s selective storytelling. Double materiality doesn’t allow for that convenience
The result is a more accurate, more honest, and frankly, a more useful disclosure. One that has long been demanded by regulators, investors, and consumers alike.
Why Double Materiality is Now Required Under CSRD
The CSRD is the EU’s most ambitious overhaul of sustainability reporting to date, a landmark regulation that applies to both EU companies and anyone wanting to do business in the EU. Making sustainability reporting mandatory, audited, and standardised is a legal obligation. It requires companies to conduct and report a double materiality assessment, with relevant and verifiable data, setting a precedent for all future ESG disclosures, reported under CSRD or not.
Who Needs to Comply With CSRD and When?
After the changes proposed under the Omnibus package and the Stop the Clock directive, here is where the CSRD timeline stands:
- 2025: Large EU public-interest entities (e.g. listed companies with >500 employees).
- 2028: All large EU companies meeting two of these three: €40M+ turnover, €20M+ total assets, or 250+ employees.
- 2029: Non-EU companies with €150M+ annual EU revenue and at least one EU branch or subsidiary.
This last group is especially relevant for fashion and textile businesses headquartered in South or Southeast Asia, regions that dominate apparel manufacturing. If your brand exports into Europe and crosses the revenue threshold, you’ll be required to disclose sustainability data using EU rules, even if you aren’t based there.
This creates new pressures: not only do you need to understand your environmental and social impacts, but you’ll need to map them across complex, often opaque, multi-tiered supply chains and report them in a structured, audit-ready format.
What Does CSRD Actually Require?
- A Double Materiality Assessment (DMA) to identify topics that are either financially material to the business, or have a significant impact on people or the environment, or both.
- Mandatory reporting in line with the ESRS, covering climate change (E1), water use (E3), pollution (E2), workers in the value chain (S2), and more.
- Inclusion of sustainability data within the management report, not as a separate brochure.
- A digital, machine-readable format (XHTML) with external assurance (audit), starting with limited assurance and moving toward reasonable assurance.
What is ESRS and How It Operationalises Double Materiality Under CSRD
The European Sustainability Reporting Standards (ESRS) are the technical backbone of CSRD. While CSRD sets the “what”, the legal requirement to report, ESRS defines the “how”.
Developed by EFRAG (European Financial Reporting Advisory Group), ESRS provides detailed guidance on what companies must report, how to structure disclosures, and how to determine which topics are material. The standards apply to all CSRD-reporting entities, regardless of industry or location.
There are two layers of standards:
- Cross-cutting standards (e.g., ESRS 1 and ESRS 2): Cover general reporting principles, governance, strategy, and materiality assessments.
- Topical standards: Cover specific ESG areas such as ESRS E1 (Climate Change), ESRS E3 (Water & Marine Resources), ESRS S2 (Workers in the Value Chain), all highly relevant for fashion.
The Role of ESRS 1: General Requirements
ESRS 1 is where Double Materiality becomes operational.
It mandates that companies perform a Double Materiality Assessment (DMA) to determine which ESG topics are relevant for disclosure. You’re not required to report on every sustainability issue, but you are required to demonstrate why you did or didn’t include each one, based on a structured assessment.
This means two things for fashion brands:
- You must show your work. Brands need to document how they identified and prioritised sustainability issues, using defined criteria such as severity, scale, and financial exposure.
- Materiality isn’t optional. Even if you believe a topic isn’t financially material (e.g., forced labour in a low-cost sourcing region), it may still be impact material and require disclosure.
While ESRS is meant to be sector-neutral, many of its topical standards touch directly on fashion’s pressure points:
- ESRS E1: Requires Scope 3 emissions reporting and transition planning, which is particularly complex in apparel due to decentralised supply chains and high product turnover.
- ESRS S2: Covers working conditions in the supply chain, wages, health & safety, freedom of association, core issues in apparel manufacturing hotspots.
- ESRS E3: Targets water withdrawal, discharges, and use, critical in dyeing and finishing hubs across South Asia and China.
The challenge? These standards still assume a level of upstream transparency that many fashion businesses have yet to achieve.
If you’re a fashion business operating in multiple geographies, outsourcing production, and selling into Europe, ESRS is your blueprint on how to collect, validate, and disclose sustainability data across your value chain.
Ignore double materiality, and you will find yourself failing audits, losing investor confidence, or facing penalties under CSRD.
How to Conduct a Double Materiality Assessment (DMA): A Step-by-Step Guide for Fashion Businesses
In theory, the DMA is a structured process to understand which sustainability issues matter most. In practice, it can be a maze, especially for fashion brands dealing with global operations, complex supply chains, and mounting ESG pressure from regulators and investors alike.
Here’s a breakdown of how to get it right and make sure it’s genuinely useful for both compliance and strategic clarity.
Step 1: Define Scope and Context
Before diving into spreadsheets or stakeholder surveys, start with the basics: who and what does this assessment cover?
- Organisational boundaries: Does your DMA include just EU operations, or global suppliers and licensees too? For CSRD, your scope should match your financial consolidation perimeter, but fashion businesses with global sourcing must look far beyond headquarters.
- Value chain mapping: Material issues often emerge far upstream, from pesticide use in cotton fields to wage theft in subcontracted factories, and far downstream, where plastic packaging and take-back schemes live. So include all stages: fibre production, Tier 1–4 suppliers, logistics, retail, use, and end-of-life.
- Time horizons: Sustainability impacts play out over years. Define what counts as short, medium, and long-term, ideally in sync with your financial planning cycle. This matters when evaluating long-tail risks like climate transitions or biodiversity loss.
Step 2: Identify a Long List of Potential Topics
This is your brainstorming phase. Be expansive, it’s better to trim later than miss something important.
- Use CSRD/ESRS as your foundation: Start with ESRS topical standards like E1 (Climate), E3 (Water), S1–S4 (Social standards), and G1 (Governance). These are your legal starting points.
- Layer in fashion-specific issues: Look beyond the rulebooks to what actually affects the industry:
- Water overuse and pollution in dyeing
- Fossil-fuel dependency in polyester production
- Living wage gaps across regions
- Deforestation tied to viscose or leather
- Microfibre shedding from synthetics
- Chemical safety and PFAS in performance wear
- Water overuse and pollution in dyeing
- Scan your peers and stakeholders: What are competitors disclosing? What’s being flagged in NGO reports, news investigations, or LCA databases? Sustainability in fashion is increasingly litigated in the court of public opinion.
Step 3: Engage Stakeholders Across the Value Chain
A credible DMA must include those most affected and those with a stake in your business.
- Map your stakeholders: Include factory workers, suppliers, internal teams, investors, community groups, and customers.
- Choose your methods: Use anonymous surveys, supplier workshops, 1:1 investor interviews, or community consultations. Match your method to the group’s power and vulnerability.
- Gather both lenses: Ask different questions depending on the stakeholder.
- Impact materiality: “How do our operations affect you or your community?”
- Financial materiality: “What ESG risks could hurt our brand or bottom line?”
- Impact materiality: “How do our operations affect you or your community?”
Engaging your Bangladeshi denim supplier may surface water stress data that a Paris HQ would otherwise miss. The same goes for feedback on chemical exposure, heat stress, or gender-based risks.
Step 4: Assess Impact Materiality (Inside-Out)
Now, evaluate how your business affects the environment and society.
Use the ESRS criteria:
- Scale: How serious is the issue (e.g., toxic effluent in local rivers)?
- Scope: How widespread (e.g., how many people or ecosystems are affected)?
- Irremediability: Can the harm be undone, or is it permanent?
Include:
- Actual impacts (e.g., documented wage theft cases)
- Potential impacts (e.g., risk of river depletion in expanding dyeing operations)
- Positive impacts too (e.g., investment in regenerative cotton)
Bonus Tip: Life Cycle Assessment tools (LCAs) can help quantify environmental impacts, while human rights assessments can capture social risks. But both must be grounded in local data, not just proxies.
Step 5: Assess Financial Materiality (Outside-In)
Now flip the lens: how do ESG factors pose risks or opportunities for your business?
Use these criteria:
- Likelihood: How probable is the risk?
- Magnitude: What’s the potential financial impact?
Examples:
- Brand damage from supplier rights violations → revenue loss
- Higher insurance premiums due to factory climate risks
- Regulatory fines over PFAS, greenwashing, or unpaid wages
- Access to green capital or lower borrowing costs from verified ESG performance
- Cost volatility due to water scarcity, carbon pricing, or material shortages
Step 6: Prioritise Final Material Topics
At this point, you bring both lenses together.
- Set thresholds: Define what counts as material. If a topic scores high on either the impact or financial axis, it qualifies.
- Sift and rank: Use a heatmap or matrix to visualise what matters most. Topics with double-high scores should drive both disclosure and internal action plans.
- Reality check: Don’t overinflate what’s material just to look good. Under CSRD, your thresholds, scoring, and topic list must stand up to auditor scrutiny.
Step 7: Validate, Approve, and Document
This isn’t just a compliance formality. The credibility of your ESG disclosure—and the decisions that flow from it- depend on this final step.
- Validation: Have your sustainability team and board sign off. Cross-check alignment with your financial disclosures, strategy, and risk registers.
- Documentation: Keep a clear trail. You’ll need to explain how you selected topics, engaged stakeholders, assessed materiality, and finalised results.
- Disclosure-ready: Your DMA must be machine-readable, XBRL-tagged, and audit-prepared for CSRD filings. That means no back-of-the-envelope spreadsheets.
The best DMAs don’t just prepare fashion businesses for regulation. They clarify where to act, what to fix, and how to lead across emissions, equity, and ethics. If you do it right, it becomes more than a risk map. It becomes a blueprint for building a better business.
How to Create a Double Materiality Matrix
If the double materiality assessment is the engine, the matrix is the dashboard. It’s how you communicate, prioritise, and drive change—visually, clearly, and with conviction.
In a world where sustainability reports are growing in complexity and length, the double materiality matrix offers what few tools can: clarity. It gives sustainability leaders, compliance teams, and board members a single visual snapshot of what matters most, and why.
What Is a Double Materiality Matrix?
The double materiality matrix is a two-axis visual that maps each sustainability topic according to its financial materiality and impact materiality. Think of it as a strategic heatmap that guides both disclosure and decision-making.
Each dot on the graph tells a story, and in fashion, those stories are often layered, nuanced, and deeply interconnected with global supply chains.
Y-Axis: Financial Materiality: Measures the risk or opportunity a topic poses to your company’s bottom line. Topics that rise high on this axis are those likely to affect cash flow, revenue, costs, or enterprise value, think carbon taxes, supply disruption, or reputational loss.
X-Axis: Impact Materiality: Captures your organisation’s actual or potential impact on people, society, and the environment. From worker welfare in Bangladesh to deforestation risk in viscose supply chains, this is where you assess the scale, scope, and irremediability of harm (or benefit).
Anything that ends up in the top-right quadrant is a material topic that fashion brands cannot afford to ignore.
Tips for Plotting Your Matrix
- Don’t just rely on instinct; use your double materiality assessment scores from both axes to plot each topic.
- Avoid overcrowding the matrix with low-priority issues; focus on those above your materiality thresholds.
- Update regularly. Your material topics will shift as policies evolve (e.g., the Green Claims Directive, CSDDD) and as your value chain changes.
- Use the matrix to engage your board; it’s a powerful governance tool for aligning ESG risks with business strategy.
When done right, the double materiality matrix is more than a compliance tool. It becomes your compass, pointing you to where impact, risk, and opportunity converge.
How Fashion Brands Are Using Double Materiality to Drive Strategy
Fashion Brands that are using double materiality to guide decision-making are already seeing dividends in resilience, innovation, and long-term value.
Here’s how some of the industry’s front-runners are putting it to work:
Kering:
In Kering’s 2023 materiality matrix, climate change topped both impact and financial risk. The company responded with regenerative agriculture, renewable energy targets, supply chain innovation and tied executive pay to emission reductions
Puma:
Puma’s assessment flagged worker wages and conditions as dual-priority topics. Instead of waiting for CSDDD enforcement, it acted, improving traceability, investing in supplier welfare, and linking labour KPIs to governance. It helped them mitigate operational risk and preserve brand reputation.
Vardhman:
Vardhman used double materiality to identify climate, water, and energy as top issues across its supply chain. Its response: invest in renewables, reduce emissions, and align disclosures with EU buyer expectations. The assessment became a roadmap for buyer trust and market access, especially in CSRD-sensitive regions.
Chloé:
Chloé’s sustainability strategy is a direct outcome of its materiality analysis. It prioritised four issues: responsible sourcing, human rights, supply chain transparency, and circularity. These priorities translated into business innovation: digital IDs for provenance checks during resale, and supplier capacity-building.
The Strategic Value of Double Materiality for Fashion Leaders
1. Holistic Risk Management
Single materiality often leads to tunnel vision. Double materiality forces brands to consider risks they cause, not just ones they face. This broader lens helps prevent nasty surprises down the road.
- Example: A supplier’s poor labour practices might seem like a reputational issue—until they lead to factory shutdowns or regulatory fines.
- By assessing social and environmental impacts alongside financial ones, brands spot long-tail risks before they explode.
2. Opportunity Discovery
When mapped correctly, materiality isn’t just about risks; it’s about unmet needs and growth white space.
- Brands can identify high-impact areas that align with shifting consumer values or upcoming regulations.
- Example: Identifying packaging waste as a top-impact issue could trigger R&D into compostable alternatives or refillable systems, futureproofing against EPR regulations while unlocking new product lines.
3. Better Decision-Making
Double materiality gives senior leaders a 360° view of the business’s role in the world, its dependencies, exposures, and impacts. That clarity informs sharper, long-term decisions.
- Where should we invest for maximum sustainability and ROI?
- Which initiatives are performative, and which are transformative?
- What data actually matters to our strategy?
4. Stronger Stakeholder Trust
Transparent disclosure builds credibility, especially when it’s based on real impact, not just PR messaging.
- A robust, well-documented materiality assessment reassures regulators, investors, employees, and conscious consumers.
- It shows you know your risks, are acting on them, and aren’t greenwashing.
5. Future-Proofing the Business
The companies thriving in the next decade will be those aligned with planetary boundaries and social expectations, not those reacting to them late.
- A double materiality approach aligns your business with tomorrow’s investor criteria, customer values, and ESG regulations.
- It also creates space for innovation, like new product models, sustainable sourcing frameworks, and next-gen compliance tech.
GRI and the Broader ESG Context: Where Double Materiality Fits In
Double materiality isn’t an isolated framework; it’s part of a bigger movement reshaping how sustainability is managed and reported across global fashion. One of the most important pieces in this puzzle is the Global Reporting Initiative (GRI), a long-standing ESG reporting standard that’s now more relevant than ever.
GRI: The Original Impact Lens
Long before CSRD made double materiality mandatory, GRI was already helping companies assess their impact on people and the planet, what we now call “impact materiality.”
- GRI’s 2021 Universal Standards require companies to disclose significant actual and potential negative impacts across their value chains.
- This makes GRI a natural entry point for fashion brands beginning their materiality journey, especially those still building internal ESG capabilities.
GRI and CSRD: Interoperable by Design
GRI and EFRAG (the body behind the ESRS) worked closely to align their standards. That’s not a coincidence, it’s a strategic lifeline.
- If your impact materiality work is already aligned with GRI, you’re partway to fulfilling CSRD’s double materiality requirements.
- For fashion companies already reporting under GRI, there’s no need to start from scratch; just expand the lens to include financial materiality.
Strategic Implications for Fashion
For brands navigating complex global supply chains and tightening EU rules, this alignment is more than a compliance shortcut; it’s a strategic advantage.
- GRI reporting helps you surface value chain blind spots, from subcontracted labour to water usage in wet processing.
- When integrated with financial assessments, it becomes the foundation for smart sustainability investments and targeted risk management.
If you’re in a sustainability or compliance role at a fashion brand or manufacturer, here’s what this means in practice:
- Use GRI-aligned impact mapping as the backbone of your double materiality process; it’s already investor- and stakeholder-credible.
- Avoid duplicative work by integrating your ESG reporting and materiality exercises around shared data, definitions, and stakeholders.
- Train cross-functional teams (finance, ESG, legal, procurement) to read from the same playbook, GRI’s frameworks help break down silos.
Conclusion
For fashion brands navigating global supply chains, shifting policies, and rising expectations, double materiality offers more than a reporting framework; it’s a strategic tool for navigating uncertainty.
The most forward-thinking companies are already using it to:
- Pinpoint their most material ESG risks and opportunities
- Align sustainability goals with business priorities
- Build trust with regulators, investors, and consumers alike
This shift, from reactive reporting to proactive planning, helps businesses stay resilient, relevant, and regulation-ready.
At Greenstitch, we help fashion and textile companies put this into practice. Our platform supports compliance heads, sustainability teams, and CXOs with the data, tools, and insights to act on what matters most.
In fashion, what you choose to see and prioritise can shape everything that follows.
