Your Company’s Carbon Footprint Is Probably 80% Larger Than You Think

Most companies that have measured their carbon footprint have measured the easy part.

They calculated how much fuel their boilers burn (Scope 1). They calculated the emissions from their electricity supplier (Scope 2). They produced a number, called it their carbon footprint, and submitted it to their buyer’s sustainability questionnaire.

For a textile manufacturer, those two scopes typically represent 10 to 30% of total emissions. The other 70 to 90% is Scope 3 — the emissions embedded in your raw materials, your logistics providers, your chemical suppliers, and eventually your customers’ use and disposal of your products.

Buyers are no longer accepting the 10–30% slice. They want the whole number. This data is also a required component of the EU Digital Product Passport for textiles — making it a legal market access requirement from 2028.

The three scopes — what they actually cover

Scope	What it covers	For a Pakistani textile manufacturer	Typical % of total footprint
Scope 1	Direct emissions from owned or controlled sources	Boilers, generators, company vehicles, on-site dyeing processes	5–15%
Scope 2	Indirect emissions from purchased electricity, heat, or steam	Grid electricity for spinning, weaving, knitting, and finishing machinery	5–20%
Scope 3	All other indirect emissions across the value chain	Cotton farming, fibre processing, yarn spinning, chemical production, ocean freight, retail energy use, product washing, end-of-life	70–90%

These figures are not estimates. They are consistent with GHG Protocol research and EcoVadis sector data across thousands of companies. For most manufacturing companies — and particularly for textile manufacturers, whose supply chains are long and energy-intensive — Scope 3 emissions dwarf Scopes 1 and 2 combined.

What is inside Scope 3 for a textile manufacturer

Scope 3 has 15 defined categories under the GHG Protocol Corporate Value Chain Standard. For a Pakistani garment or fabric manufacturer, the most significant are typically:

• Purchased goods and services — the carbon embedded in the cotton, polyester, dyes, chemicals, and packaging you buy. Cotton cultivation alone is highly carbon and water intensive.
• Upstream transportation — shipping raw materials and yarn to your facility
• Downstream transportation — ocean freight of finished goods to EU, US, and Gulf markets
• Use of sold products — the energy and water used by consumers to wash, dry, and iron your garments over their lifetime. A cotton T-shirt washed regularly over 2 years has significant lifetime emissions from consumer use.
• End-of-life treatment — what happens when the garment reaches the end of its useful life: landfill, incineration, or recycling

Upstream and downstream transportation together account for a meaningful share of Pakistan-specific Scope 3 emissions, given that most export destinations are 6,000 to 12,000 km away and ocean freight is a significant emission source.

How to calculate Scope 3 emissions for a textile factory — the practical steps

This is the question buyers are implicitly asking when they request Scope 3 data — and the question most Pakistani factories cannot currently answer. Here is what the process actually involves.

Step 1: Define your boundary and reporting year. Identify which entities are included in your inventory (one factory? Multiple sites? The whole company?), and select the reporting year. GHG Protocol recommends a calendar year or financial year consistently applied.

Step 2: Collect Scope 1 and 2 data first. These are the direct inputs: fuel consumption (natural gas, HFO, coal, diesel) from utility invoices and fuel purchase records; electricity consumption in kWh from electricity bills; steam or heat from external sources. Apply the relevant emission factors — for Pakistan’s electricity grid, NEPRA’s grid emission factor is the reference.

Step 3: Map your Scope 3 categories. A textile manufacturer typically has significant Scope 3 in categories 1 (purchased goods), 4 (upstream transport), 11 (use of sold products), and 12 (end-of-life). Screen all 15 categories and prioritise the ones estimated to represent more than 1% of your total footprint.

Step 4: Collect Scope 3 activity data. For purchased goods: weight of raw materials (cotton, polyester, dyes, chemicals, packaging) purchased per year. For transport: container counts and distances, with mode (ocean, road, air). For product use: unit production volumes, product weight and wash cycles per year. This data comes from procurement records, logistics invoices, and production data — not estimates.

Step 5: Apply emission factors. Use published emission factor databases — IPCC, ecoinvent, GHG Protocol supply chain tools, or sector-specific databases. For textiles, the Textile Exchange’s Preferred Fiber and Materials Market Report and Higg MSI (Materials Sustainability Index) provide material-specific emission factors.

Step 6: Have the inventory third-party verified. Buyers increasingly require third-party assured GHG inventories. The GHG Protocol Corporate Standard includes guidance on assurance. For DPP purposes and CSRD supplier data requests, third-party verification by a qualified body is expected standard.

Why buyers are now asking for Scope 3 data

Three regulatory and commercial developments have converged to make Scope 3 a standard buyer requirement:

1. Science-Based Targets (SBTi): Companies that have committed to SBTi net zero targets — including most major fashion brands — are required to include Scope 3 in their reduction targets. That requirement flows down to their suppliers: you cannot reduce your Scope 3 if your suppliers do not measure and report their emissions.
2. IFRS S1 and S2 (SECP mandate, Pakistan): Pakistan’s Securities and Exchange Commission of Pakistan (SECP) has mandated IFRS S1 and S2 disclosures for listed companies, which require climate-related risk and emissions reporting including Scope 3.
3. EU Corporate Sustainability Reporting Directive (CSRD): Large EU companies filing CSRD reports are required to report their full Scope 3 value chain emissions — which means their Pakistani suppliers must provide emissions data or be excluded from reporting.

The pattern is consistent across all three: the regulation sits with the buyer, but the data requirement flows to the supplier. If you cannot provide your Scope 3 emissions data in a format your buyer can use, you become a problem in their compliance process. Problems in their compliance process get replaced.

Frequently asked questions about Scope 3 emissions for textile manufacturers

What is the difference between Scope 3 upstream and downstream emissions?

Upstream Scope 3 emissions are those that occur before your factory — in your supply chain. They include the carbon embedded in the raw materials you buy, the emissions from transporting those materials to your site, and the emissions from your suppliers’ energy use. Downstream Scope 3 emissions are those that occur after your factory — in the use and end-of-life of your product. They include consumer washing and drying of garments, retail store energy use, transportation of finished goods to market, and eventual disposal or recycling. For Pakistani garment exporters, upstream emissions (especially from cotton cultivation and synthetic fibre production) and downstream transportation (ocean freight) are typically the largest categories.

Do I need to collect Scope 3 data from all my suppliers?

Not necessarily from all, but from those that represent the largest share of your emissions. GHG Protocol recommends a screening exercise first — identifying which Scope 3 categories are significant (above 1% of total estimated footprint) and focusing data collection effort there. In practice, cotton and synthetic fibre suppliers, and logistics providers, are the Scope 3 sources that warrant primary data collection. For smaller categories, industry-average emission factors are acceptable under GHG Protocol guidance, provided you document the methodology.

Can I use the Higg FEM or EcoVadis to satisfy my buyer’s Scope 3 requirement?

Higg FEM (Facility Environmental Module) captures some energy and emissions data, but it is a facility-level tool and does not produce a complete Scope 3 inventory as defined by the GHG Protocol Corporate Value Chain Standard. EcoVadis is a supplier ratings platform that uses submitted data to produce sustainability scores. Neither fully substitutes for a standalone GHG inventory report. If your buyer requests a “Scope 3 inventory,” they typically mean a GHG Protocol-compliant document with documented methodology and third-party verification — not a Higg or EcoVadis score. Confirm with your buyer what specific format they need before commissioning any particular approach.

How long does a first Scope 3 inventory take?

A credible first-time Scope 3 inventory for a mid-size Pakistani textile manufacturer typically takes 3 to 6 months from project initiation to final verified report. The timeline is driven by data collection — procurement records, logistics invoices, utility data, production volumes — which often requires chasing multiple departments and suppliers. Factories that have centralised procurement data and good record-keeping can compress the timeline. Factories with fragmented records or multiple production sites may take longer. Starting before your buyer requests it — rather than scrambling to produce it in response to a questionnaire — gives you control over the timeline and quality of the output.

The dataset you build once but use five times

This is the part most Pakistani manufacturers do not realise until they start the process.

A credible GHG inventory — Scope 1, 2, and 3 — requires collecting actual data: utility bills, fuel consumption records, freight invoices, chemical purchase records, production volumes. It is not a quick exercise. A first-time inventory typically takes 3 to 6 months to produce properly.

But once it exists, that dataset supports five separate applications:

Application	Who requires it
Buyer sustainability questionnaire responses (Higg FEM, CDP, etc.)	H&M, Inditex, PVH, Primark, and most global brands
ESG reporting (GRI, CSRD, IFRS S2)	Listed companies in Pakistan under SECP mandate; EU buyers under CSRD
SBTi net zero target setting and annual progress reporting	Companies voluntarily committing to science-based targets
EU Digital Product Passport carbon footprint data	All textile exporters to the EU market from 2028 onward
Carbon credit project documentation (for eligible facilities)	UNFCCC Article 6 carbon market participation

The GHG data your buyer is asking for today is the same data that will underpin your EU Digital Product Passport in 2028 and your SBTi target in 2029. You are not collecting it for one buyer. You are building an asset that serves your business across multiple requirements simultaneously.

Pakistan’s position on the global emissions map

Pakistan contributes approximately 1% of global greenhouse gas emissions — one of the lowest per-capita rates among major economies. Yet the country is among the world’s most climate-vulnerable: ranked among the top 10 most climate-affected countries by the Global Climate Risk Index, with devastating floods in 2022 and 2023 that caused combined economic losses exceeding USD 30 billion.

Pakistan’s NDC 3.0, submitted to the UNFCCC, commits to a 50% reduction in GHG emissions by 2035 relative to business-as-usual, requiring an estimated USD 565.7 billion in climate finance. That finance flows toward companies and projects that can demonstrate verified emissions data.

For Pakistani manufacturers, this creates an unusual dynamic: measuring your carbon footprint is not just about satisfying buyers. It positions you within a climate finance landscape that is actively looking for credible projects in Pakistan’s manufacturing sector.
