CBAM Garment Factory Guide: What Bangladesh, India, and Vietnam Need to Do Before 2026

Every article about CBAM lists the same six regulated sectors — cement, steel, aluminium, fertilizers, electricity, hydrogen — and stops there. None of them explain what a CBAM garment factory in Dhaka, Tirupur, or Ho Chi Minh City is supposed to do. This is the factory-side story: what CBAM actually is, why it matters to textiles right now even though garments are not in scope yet, and what factories should be building today so they are not scrambling when the expansion wave arrives.

What Is CBAM and Why Should Garment Factories Care Now

The Carbon Border Adjustment Mechanism — CBAM — is an EU regulation that puts a carbon price on imports of goods produced in countries with weaker or no carbon pricing. The idea is straightforward: if you manufacture in the EU, you already pay for carbon through the EU Emissions Trading System (EU ETS). CBAM prevents "carbon leakage" — where EU manufacturers move production outside the EU specifically to avoid paying for emissions. Under CBAM, importers bringing these goods into the EU must purchase CBAM certificates equivalent to the carbon price their overseas manufacturer would have paid had they produced inside the EU.

The mechanism entered a transitional reporting phase in October 2023 and reached full pricing implementation in January 2026 for its first-wave sectors. For a CBAM garment factory audience, the immediate question is obvious: are we in scope? The answer is not yet — but the follow-on answer matters just as much: your EU buyers are already asking for carbon data anyway, and the factories that cannot provide it are already losing specification discussions.

Understanding the regulatory architecture of CBAM, even for sectors not yet covered, is not academic. It is the single most important thing a garment factory manager can do in 2026 to protect their order pipeline over the next five years. The textile and apparel expansion is not speculative — it is formally proposed and moving through the EU legislative process. The transition phase gave importers time to build reporting infrastructure. Factories that wait for formal inclusion will be two years behind buyers who are already standardizing their supplier carbon data requirements now.

Is CBAM Affecting Garments Yet? (The Honest Answer)

No. As of April 2026, garments and textiles are not within CBAM scope. Phase 1 covers only cement, steel, aluminium, fertilizers, electricity, and hydrogen — sectors selected because their carbon intensity is high, their trade volumes are large, and the EU ETS had already established pricing benchmarks that made CBAM certificate valuation feasible.

Garments present a different measurement challenge. A tonne of cement has a fairly predictable carbon profile tied to kiln temperatures, fuel mix, and clinker ratio. A cotton T-shirt's embedded carbon spans field irrigation in Texas, ginning in Gujarat, spinning in Vietnam, knitting in Bangladesh, dyeing in China, and final assembly wherever the cheapest CMT rate was found that season. Measuring and verifying that full lifecycle carbon footprint at the product level requires supply chain traceability infrastructure that most garment supply chains do not have yet.

The EU knows this. The formal CBAM expansion proposal, tabled by the European Commission as part of the broader carbon leakage review, identifies textiles and apparel as a priority sector for Phase 2 consideration. Industry working groups expect formal textile inclusion to be legislated around 2027–2028, with a transitional reporting phase running to 2030 before full pricing kicks in. That timeline sounds distant. It is not.

Why EU Buyers Are Asking for Carbon Data Anyway

Even though garments sit outside CBAM today, the demand for factory-level carbon data from EU buyers has accelerated sharply since 2024. There are three distinct regulatory drivers behind this pressure — and CBAM is only one of them.

The first driver is the EU Corporate Sustainability Reporting Directive (CSRD). Large EU companies — which include most major fashion brands and retailers — are required under CSRD to disclose audited ESG data covering their entire value chain. That explicitly includes Scope 3 emissions: the carbon embedded in the goods they buy from overseas factories. A brand cannot file a complete CSRD report without carbon intensity data from their top-tier suppliers. They need your factory's energy consumption figures, production volumes, and ideally your carbon intensity per unit of output. See our detailed guide on CSRD reporting for garment factories for the full picture of what this means for data collection.

CSRD Wave 1 — the largest EU brands with more than 1,000 employees and €450M+ turnover — already filed their first sustainability reports covering FY 2024 data in 2025. These reports require Scope 3 disclosures. Scope 3 emissions account for up to 96% of fashion brands' total carbon footprint, with Tier 2 suppliers (fabric mills and yarn producers) contributing 45–70% of that figure. Even CMT-only factories — Tier 3 in the supply chain — are being asked to provide energy and production volume data so brands can estimate downstream emissions. The expectation is now set at the board level: if your factory is in a Wave 1 brand's supply chain, the request is not hypothetical — it has already arrived or will arrive before the next sourcing season.

The second driver is voluntary net-zero commitments. After a wave of Science Based Targets initiative (SBTi) pledges from brands between 2020 and 2023, large buyers now have board-level carbon reduction targets with verifiable milestones. Their procurement teams are under direct pressure to demonstrate Scope 3 reductions year-on-year. The simplest way to do this is to shift orders toward factories with lower, documented carbon intensity — and away from factories they simply cannot measure.

The third driver is the EU Green Claims Directive, which requires brands to substantiate any environmental claim they make about their products with third-party verified lifecycle data. A brand that markets a garment as "lower carbon" needs the factory-level energy and production data to back that claim. Without it, the claim is legally non-compliant. Without factory cooperation, the brand cannot make the claim at all.

Add these three together and the commercial picture becomes clear: an EU buyer's compliance, reporting, and marketing functions all converge on the same ask — give us your carbon data. The CBAM garment factory that has this data ready gains a genuine commercial advantage. The factory that does not is a liability in more than one buyer department simultaneously.

The 3 Carbon Metrics EU Buyers Are Already Requesting

When buyers ask for carbon data from a CMT garment factory, they are typically requesting information that maps to the three Scope categories established under the GHG Protocol — the international standard that CSRD, CBAM, and most corporate carbon accounting frameworks reference.

Scope 1 — Direct emissions from the factory. This covers fuel burned on-site: diesel generators, gas boilers for steam pressing, LPG for finishing operations. For a sewing-only CMT factory, Scope 1 is often the smallest of the three scopes. The main Scope 1 source in most South and Southeast Asian factories is diesel generation — either as backup power or, in factories with unreliable grid supply, as primary power for parts of the working day. To calculate Scope 1, you need diesel consumption records in litres per month and the appropriate emission factor for your generator type (approximately 2.68 kg CO₂ per litre of diesel combusted).

Scope 2 — Purchased electricity. This is the dominant carbon source for a garment factory, and the most tractable to measure and reduce. Electricity consumed by sewing machines, overlock machines, lighting, compressors, and air conditioning all falls into Scope 2. The carbon intensity of that electricity depends on the national or regional grid emission factor — Bangladesh's grid has historically been among the higher-carbon grids in Asia due to heavy gas and oil dependence, while Vietnam has been improving rapidly through hydropower and solar expansion. To calculate Scope 2, you need your monthly electricity bill in kWh and your country's published grid emission factor.

Scope 3 — Value chain emissions. For a garment factory selling to EU brands, the relevant Scope 3 categories are fabric and trim inputs (upstream) and transport to port (downstream). Scope 3 is the hardest to calculate precisely and the one most buyers have the least expectation of receiving in the first data request. What most buyers actually ask for at the factory audit stage is your Scope 1 and Scope 2 data, plus your total production volume in pieces — from which they calculate a carbon intensity ratio (kg CO₂ per garment) for their own Scope 3 reporting purposes.

In practice, a CBAM garment factory audit from an EU buyer in 2026 looks something like this: provide your electricity bills for the last 12 months in kWh, your diesel consumption if any, your total pieces produced by month, and if you have it, your line-level energy metering data. That is the floor expectation. Factories that can provide this within a week have a clear advantage over factories that need three weeks to reconstruct it from scattered utility bills and paper production records.

The most common request from EU buyers right now is the Higg Facility Environmental Module (FEM) — a standardised questionnaire covering energy consumption, water use, waste, and GHG emissions at the factory level. Major brands including H&M, Adidas, Nike, Patagonia, and Levi's use Higg FEM data to populate their own annual Scope 3 accounting under GHG Protocol Category 1. If you have not received a Higg FEM verification request yet, it is worth checking whether your buyer's compliance portal already has one pending — many brands send these through third-party verification platforms rather than direct email, and factory compliance teams miss them as a result.

What Garment Factories Can Do Today to Prepare

Preparation for CBAM-era carbon reporting does not require a sustainability consultant, a net-zero strategy, or an expensive third-party certification. It requires building the data infrastructure that makes carbon calculation possible — and most of that infrastructure overlaps with factory digitization work that delivers operational benefits independently of any regulatory purpose.

Step 1: Get your electricity baseline. Pull your last 12 months of utility bills and record kWh by month. If your factory has multiple meters — production floors, finishing areas, common areas, canteen — document which meter covers which area. This alone gives you a Scope 2 baseline that covers over 90% of what EU buyers currently ask for from CMT factories. Convert to CO₂ using your country's grid emission factor: Bangladesh approximately 0.60 kg CO₂/kWh, India varies by state (0.50–0.82 kg CO₂/kWh on the national average of about 0.71), Vietnam approximately 0.49 kg CO₂/kWh as of 2024 grid data.

Step 2: Connect production volume records to utility billing periods. Carbon intensity (kg CO₂ per piece) requires two data points: energy consumed in a period and pieces produced in the same period. If production tracking is currently on paper tally sheets, the missing link is piece-count data at the lot level over monthly periods. A factory running digital production tracking — QR scanning, piece-rate recording, or any system that logs completed units by date — already has this second data point in a queryable form.

Step 3: Install sub-metering on at least one production line. Even a single sewing line with energy metering gives you a verifiable intensity figure you can present to buyers, along with a methodology statement about how it was measured. This is significantly more credible than estimates derived from whole-factory electricity bills. It also gives you a baseline against which to track efficiency improvements over time — which is the next conversation buyers will initiate after they have the initial data.

Step 4: Document your diesel and generator usage. Maintain a monthly log of diesel purchases and generator run hours. This is simple to do prospectively — ask your generator room operator to keep a daily log — and gives you the Scope 1 data that completes the picture. Many factories in Bangladesh and Nepal run diesel generators for four to eight hours per day due to grid unreliability. That volume of diesel combustion is a meaningful Scope 1 figure that belongs in any complete carbon disclosure.

Step 5: Assign internal ownership. Carbon data collection without internal accountability does not persist through seasonal reporting cycles. Assign one person — an operations manager, a compliance officer, or a production administrator — with explicit responsibility for maintaining the energy log, collecting utility bills, and being the point of contact for buyer carbon questionnaires. In most factories of 200–500 workers, this adds less than two hours per month to one person's responsibilities, provided the data collection systems are already in place.

How Factory Management Software Helps Track Carbon Data

The link between a factory ERP system and carbon reporting is less obvious than it might appear — but it is real and it matters. Carbon intensity calculation requires production volume data at the same temporal granularity as your energy data. If energy data is available monthly and production data is available daily, you can produce monthly intensity figures and also identify whether high-production months show improved or degraded carbon efficiency (they almost always improve, since fixed lighting and HVAC loads are spread over more units).

A factory management system that records every completed operation — by lot, by operator, by date — gives you production volume data that is already structured for carbon intensity calculation. When Scan ERP logs a completed bundle scan, it records the article code, lot number, production date, piece count, and operator ID. Aggregating completed pieces by lot and date is a standard report. When that report is matched against the energy metering data covering the same lot production period, the result is a per-lot carbon intensity figure expressed in kg CO₂ per piece.

This is what the carbon footprint tracking module in Scan ERP does: it connects production lot records to energy input data so that carbon intensity is calculated at the lot level, not just the factory-month level. That granularity matters when a buyer asks: "What was the carbon footprint of the 12,000 pieces of style S27 you produced for us in February?" A factory that can answer that question with a documented methodology and a specific number is operationally differentiated. A factory that says "we used X amount of electricity this month across all production" is providing factory-level data that the buyer still has to apportion themselves — with assumptions they may not favour you.

Beyond carbon tracking, digital production management contributes to several carbon reduction levers that buyers increasingly audit for. Line efficiency improvements directly reduce Scope 2 intensity per piece: if a 24-machine line produces 320 pieces per day versus 240, the kWh per piece falls by 25% for the same machines running the same hours. Fabric waste reduction matters for Scope 3 intensity. Operator scheduling efficiency reduces idle machine time. All of these are operational benefits that ERP systems are built to optimize — and they all have a carbon intensity dimension that becomes reportable with the right data infrastructure in place.

The Timeline: When Textiles Will Likely Enter CBAM Scope

The EU's legislative process for CBAM expansion follows a defined sequence: Commission proposal, impact assessment, inter-institutional negotiation (Council and Parliament), final adoption, and then an implementation period before enforcement. For textiles, the trajectory based on current legislative signals looks approximately like this:

This timeline involves legislative uncertainty. The EU has a history of delaying implementation when supply chain complexity makes measurement difficult — the CSRD timeline itself was revised multiple times as the Commission grappled with SME reporting capacity. CBAM textile inclusion could move faster if the EU carbon leakage review produces strong evidence of textile sector carbon leakage, or slower if trade negotiations with major textile exporters (Bangladesh, India, Vietnam, Cambodia) lead to bilateral agreements on carbon pricing equivalence.

What is not uncertain is the buyer-side pressure. The brands sourcing from CBAM garment factory suppliers have their own CSRD deadlines, their own SBTi commitments, and their own board-level sustainability targets. Those are not contingent on the EU legislative calendar. They are happening right now, on the brands' own timelines, and the factory carbon data they require is being built into supplier scorecards that will determine order allocation for the 2027 and 2028 seasons.

There is a second-order commercial risk that rarely appears in CBAM coverage aimed at factories. When CBAM certificates become required for textile imports, the cost of those certificates is borne by the EU importer — the brand or retailer — not the factory directly. But the importer will calculate the certificate cost against each supplier based on the embedded carbon of that supplier's production. A factory with a documented, lower carbon intensity generates fewer certificate obligations for the brand. That is a direct cost saving to the buyer that they can quantify per order. Over time, buyers will price this into their CMT rate negotiations or use it as a selection criterion when two factories quote similar prices. The CBAM garment factory that has built verifiable low-carbon production data is not just compliant — it is competitively positioned.

Bangladesh's exposure to the CBAM-era carbon pricing trajectory is particularly stark. A study cited by TBS News warns that Bangladeshi RMG exports could face a 4.8–5% CBAM tax after 2030 if garments enter scope. Bangladesh risks losing 30% of its EU garment exports if decarbonisation gaps persist — currently only 5.38% of Bangladesh's electricity comes from renewable sources, against buyer expectations of 30%+ by 2030. BGMEA has signed the UN Fashion Industry Charter for Climate Action and committed to 30% GHG reduction by 2030, but the infrastructure to get there is still nascent. For factories in Bangladesh, the commercial urgency of carbon data collection is higher than in any other sourcing country — the gap between current performance and buyer expectations is widest, and the EU export exposure is proportionally greatest.

The factories currently leading on carbon data collection are concentrated in a few pockets: some large export manufacturers in Bangladesh (particularly those in BGMEA's sustainability programs), GOTS-certified facilities in India, and the tier-1 export factories in Vietnam that already report to brands under Higg FEM (Facility Environmental Module) or similar frameworks. These factories represent a small minority of total production capacity in each country. The gap between them and the rest of the industry is not primarily a technology gap — it is a data habit gap. Factories that have not started collecting structured energy and production data are not behind because the technology was unavailable. They are behind because no one treated the data collection as urgent. That calculus changed in 2026.
