The garment and textile industry is one of the biggest manufacturing sectors on earth. It makes the clothes, home textiles and fashion items billions of people use every day and it drives jobs and trade across many countries. But it's also one of the largest sources of carbon emissions in the world.
Almost every step of making a piece of clothing burns energy or uses resources that release carbon — growing fiber, spinning yarn, weaving, dyeing, sewing, packing and shipping. Because of this, brands, retailers, investors and governments are pushing manufacturers harder than ever to clean up their operations. Many big fashion brands have already promised to cut emissions across their supply chains, which means the mills and factories that supply them now have to change how they work and prove it with real data. Frameworks like the Greenhouse Gas (GHG) Protocol have become the standard way companies measure and report their carbon output.
For textile manufacturers, cutting emissions isn't a nice-to-have anymore — it's becoming a basic requirement to stay in business. Companies that invest in cleaner production tend to save money, keep customers happy, run more efficiently and gain easier access to green financing. Companies that don't adapt risk higher costs, more regulation and fewer export opportunities.
Where the Emissions Come From
Emissions from textile production fall into two categories. Direct emissions happen when factories burn fuel — coal, gas, diesel — to make steam, heat or electricity on-site. Indirect emissions come from the electricity a factory buys, plus everything upstream and downstream, like growing raw materials and shipping goods.
Textile manufacturing is heat-hungry. Dyeing, washing, bleaching and finishing all rely on boilers and steam systems running almost non-stop. In countries where electricity still comes mostly from fossil fuels, factories add to their footprint just by plugging in. Raw materials matter too — polyester depends on oil and gas, while conventional cotton needs huge amounts of water, fertilizer and land.
| Stage | Main Activities | Emission Source | Impact |
|---|---|---|---|
| Fiber production | Cotton farming, polyester production | Fertilizer, energy, petrochemicals | Very high |
| Spinning | Yarn production | Electricity | Medium |
| Weaving & knitting | Fabric production | Machine electricity | Medium |
| Dyeing & finishing | Washing, bleaching, dyeing | Steam, boilers, chemicals | Very high |
| Garment making | Cutting, sewing, ironing | Electricity, compressed air | Medium |
| Packaging | Cartons, plastics, labels | Material production | Low–medium |
| Shipping | Truck, sea, air freight | Fuel | Medium–high |
| Waste disposal | Landfill, incineration | Methane, CO₂ | Medium |
Dyeing and finishing usually stand out as the biggest offenders because they need so much heat and shipping adds up fast once you consider how far garments travel before reaching a store.
Why It's a Business Issue, Not Just an Environmental One
Cutting emissions and cutting costs often go hand in hand — using less energy usually means smaller electricity and fuel bills, which improves margins. Big brands increasingly require suppliers to report emissions and set real reduction targets and sustainability performance now factors into sourcing decisions. Governments are also tightening environmental rules, so factories that start early avoid scrambling to catch up later.
Start With Energy Efficiency
Before spending on new technology, most factories can save a lot of energy simply by fixing what they already have — usually the cheapest, fastest place to start.
- Run regular energy audits
- Install energy-efficient motors and variable frequency drives (VFDs)
- Fix leaks and upgrade compressed air systems
- Improve boiler efficiency and insulate steam pipes
- Switch to LED lighting
- Track energy use digitally
Switching to Renewable Energy
Efficiency alone isn't enough — real reductions require moving away from fossil fuels.
Solar power suits factories well, since most have large rooftops for panels, cutting grid dependence and stabilizing costs.
Biomass boilers burn agricultural residue or wood waste instead of coal or oil, cutting net emissions when sourced responsibly.
Factories can also buy clean electricity through power purchase agreements, which directly reduces "Scope 2" emissions — the carbon tied to purchased power.
Choosing Better Materials
What a garment is made from matters as much as how it's made. The industry is shifting toward recycled and lower-impact fibers to shrink the footprint before manufacturing even starts.
| Conventional | Alternative |
|---|---|
| Virgin polyester | Recycled polyester (rPET) |
| Conventional cotton | Organic cotton |
| Virgin nylon | Recycled nylon |
| Synthetic fibers | Bio-based fibers |
This lowers emissions, cuts oil dependence, reduces waste and supports circularity, while strengthening brand appeal with eco-conscious shoppers.
Water, Chemicals and Circularity
Wet processing uses huge amounts of hot water and heating it takes energy — so improving water efficiency cuts both emissions and fuel costs. Useful steps include low-liquor-ratio dyeing machines, wastewater recycling, precise chemical dosing, digital printing and heat recovery from hot water streams.
Beyond process improvements, the industry is also shifting from a linear "make, use, dispose" model toward circularity — a shift the EU's textile strategy actively promotes through durability, repairability and recycled fiber use.
The core principles are simple:
reduce fabric waste and overproduction,
reuse scraps and support repair programs,
recycle old textiles into new fiber
recover value from waste that can't be reused. Each of these cuts how much new material has to be produced from scratch.
Logistics and Smart Manufacturing
Garments often travel thousands of miles before reaching a customer, so smarter routing, consolidated shipments, more sea freight (instead of air), efficient warehousing and electric transport all help cut logistics emissions. On the factory floor, digital tools — IoT energy monitoring, digital twins, automated controls, predictive maintenance and AI-based optimization — help managers spot waste in real time and fix it before it adds up.
Measuring, Reporting and Setting Targets
You can't manage what you don't measure. The GHG Protocol remains the standard framework, split into three scopes:
| Scope | Covers | Textile Example |
|---|---|---|
| Scope 1 | Direct emissions | Boilers, generators, vehicles |
| Scope 2 | Purchased electricity | Factory power use |
| Scope 3 | Supply chain | Raw materials, logistics, waste |
A solid process looks like this: define boundaries, collect data, calculate emissions, find hotspots, set targets, track progress yearly and report honestly. A simple five-year roadmap might run:
Year 1 – establish a baseline,
Year 2 – cut energy use 10%,
Year 3 – install renewables
Year 4 – increase recycled material use
Year 5 – reach a 25–30% overall reduction
Challenges and Payoffs
The barriers are real: high upfront costs, limited renewable infrastructure, skill gaps, complex supply chains and difficulty sourcing sustainable materials at scale. But progress usually comes from a mix of government support, industry collaboration and long-term investment rather than any single fix.
The payoff is broad — lower emissions and pollution environmentally; lower energy costs and easier green financing for the business; better working conditions and reputation socially; and stronger buyer relationships and export access commercially.
What is GHG Emissions (Tonnes CO₂e)?
GHG Emissions (Tonnes CO₂e) represent the total amount of greenhouse gases released by an organization, product or activity, expressed as the equivalent amount of carbon dioxide. This metric combines the warming effects of carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O) and other greenhouse gases into a single measurement, enabling organizations to track, compare and reduce their climate impact effectively.
Why CO₂e is Used
Not all greenhouse gases contribute equally to global warming. For example:
| Greenhouse Gas | Abbreviation | Global Warming Impact* |
|---|---|---|
| Carbon Dioxide | CO₂ | 1 |
| Methane | CH₄ | ~28 times higher than CO₂ |
| Nitrous Oxide | N₂O | ~265 times higher than CO₂ |
*Measured over a 100-year period.
To simplify reporting, all greenhouse gases are converted into a single unit called CO₂ equivalent (CO₂e).
Example:
- 1 tonne of CO₂ = 1 tonne CO₂e
- 1 tonne of Methane (CH₄) ≈ 28 tonnes CO₂e
- 1 tonne of Nitrous Oxide (N₂O) ≈ 265 tonnes CO₂e
Formula
CO₂e = Amount of Gas × Global Warming Pot*ntial (GWP)
Example:
10 tonnes CH₄ × 28 = 280 tonnes CO*e
Understanding Apparel Brand Emissions
Greenhouse Gas (GHG) emissions are measured in tonnes of carbon dioxide equivalent (tCO₂e), a universal metric used to express the total climate impact of different greenhouse gases in a single unit. This measurement combines emissions from carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O) and other greenhouse gases based on their respective global warming potential.
When a sustainability report states that Nike's total GHG emissions are approximately 8.27 million tCO₂e, it means the combined impact of all greenhouse gases generated across the company's operations and value chain is equivalent to releasing 8.27 million tonnes of carbon dioxide into the atmosphere.
Similarly, when Adidas reports total GHG emissions of approximately 6.36 million tCO₂e, it indicates that the overall climate impact of its business activities, including manufacturing, material sourcing, transportation and operations, is equal to approximately 6.36 million tonnes of carbon dioxide emissions.
For most apparel brands, carbon emissions are categorized into three main areas:
| Scope | Description | Textile Industry Example |
|---|---|---|
| Scope 1 | Direct emissions from owned sources | Boilers, generators, company vehicles |
| Scope 2 | Indirect emissions from purchased electricity | Factory electricity consumption |
| Scope 3 | Upstream and downstream value chain emissions | Fabric production, raw materials, logistics, waste disposal |
In the fashion and textile industry, Scope 3 emissions typically account for more than 90% of total emissions, making supply chain decarbonization a critical priority for global brands.
Example of Total GHG Emissions
| Brand | Total GHG Emissions (tCO₂e) |
|---|---|
| Nike | ~8.27 Million |
| Adidas | ~6.36 Million |
| H&M Group | Millions of tCO₂e across global value chain |
| Inditex (Zara) | Millions of tCO₂e across global value chain |
These figures represent the total carbon footprint generated by each company's global operations, manufacturing activities, supply chain processes, transportation networks and product lifecycle.
As a result, leading apparel brands are increasingly investing in renewable energy, sustainable materials, energy-efficient manufacturing and circular economy initiatives to reduce greenhouse gas emissions and move toward net-zero climate targets.
Example for a Garment Factory
Suppose a garment factory annually consumes:
| Source | Emissions |
|---|---|
| Diesel Generator | 500 tCO₂e |
| Purchased Electricity | 2,000 tCO₂e |
| Raw Materials & Transportation | 3,500 tCO₂e |
| Total GHG Em* | 6,000 tCO₂e |
The factory's annual carbon footprint would be reported as:
Total GHG Emissions = 6,000 tonnes CO₂e
Total GHG Emissions of Leading Apparel Brands
Greenhouse Gas (GHG) emissions represent the total climate impact of a company's operations and value chain. The figures below include Scope 1 (direct emissions), Scope 2 (purchased energy emissions) and Scope 3 (supply chain emissions) and are expressed in tonnes of carbon dioxide equivalent (tCO₂e).
To provide a sense of scale, the table below summarizes the most recently reported GHG emissions of several leading global apparel brands. While some companies have already published 2025 data, others have reported their latest available figures based on fiscal-year reporting cycles.
Total GHG Emissions of Major Apparel Brands
| Brand | Total GHG Emissions (tCO₂e) | Reporting Year |
|---|---|---|
| Inditex (Zara) | ~12.7 Million | FY2025 |
| Nike | ~8.5 Million | FY2024 |
| Adidas | ~6.4 Million | FY2025 |
| H&M Group | ~5.7 Million* | FY2024 |
| Uniqlo (Fast Retailing) | ~5.5 Million | FY2024 |
| Levi Strauss & Co. | ~3.7 Million | FY2023 |
| PVH Corp. (Tommy Hilfiger & Calvin Klein) | ~2.3 Million | FY2023 |
| Patagonia | ~0.2 Million | FY2023 |
*H&M Group has reported substantial reductions in value chain emissions compared with its baseline year, although a new consolidated emissions total has not yet been published.
What Do These Numbers Mean?
A company reporting 1 million tCO₂e means its activities generated greenhouse gases with the same global warming effect as releasing 1 million tonnes of carbon dioxide into the atmosphere.
For example:
- Nike's footprint of approximately 8.5 million tCO₂e is comparable to the annual emissions of a medium-sized city.
- Adidas' footprint of approximately 6.4 million tCO₂e highlights the significant environmental impact associated with global sourcing, manufacturing, transportation and retail operations.
- Patagonia's comparatively lower emissions reflect its smaller business scale and long-standing focus on sustainable materials, renewable energy and circular business practices.
Why Are Emissions So High?
For apparel brands, the majority of emissions are generated outside their own offices and stores. Most emissions occur within the supply chain, particularly during:
- Raw material production
- Fiber manufacturing
- Spinning and weaving
- Dyeing and finishing
- Garment manufacturing
- Transportation and logistics
- Product disposal and end-of-life treatment
As a result, many global brands are focusing their climate strategies on improving supplier efficiency, increasing renewable energy use, eliminating coal-fired boilers, adopting sustainable materials and investing in circular economy initiatives.
Typical Source of Emissions in the Fashion Industry
| Emission Source | Share of Total Emissions |
|---|---|
| Raw Materials Production | 30-40% |
| Textile Manufacturing | 20-30% |
| Garment Manufacturing | 10-20% |
| Transportation & Logistics | 5-10% |
| Retail Operations | Less than 5% |
| Product End-of-Life | 5-10% |

These commitments are driving significant changes across the textile and garment industry, creating new opportunities for manufacturers that invest in energy efficiency, renewable energy, sustainable materials and carbon management programs.
How Leading Global Brands Are Working to Cut Carbon Emissions
Major fashion and apparel brands are setting bigger and bolder climate goals as part of their broader sustainability plans. Since so much of fashion's environmental impact happens before a product ever reaches a store — in raw materials and manufacturing — brands are teaming up with textile mills, garment factories and suppliers to bring emissions down across the whole value chain. These efforts are reshaping the industry and raising the bar for what suppliers everywhere are expected to do.
Why Brands Are Leading This Push
For most apparel companies, more than 70% of total emissions come from their supply chains, not their own offices or stores. That's why brands are focusing so heavily on renewable energy, better material sourcing, circular business practices and closer work with suppliers to hit their climate targets. Suppliers who keep pace with these efforts tend to land longer-term partnerships and stronger relationships with the brands they work with.
