The carbon footprint of a garment indicates how many kilograms of CO2 equivalents (kg CO2e) are generated over its entire life cycle, from raw material extraction to disposal. Depending on the production location and usage, a simple cotton T-shirt causes between approximately 2 and 10 kg CO2e. According to analyses, jeans range between 5.14 and 24 kg CO2e. The single biggest lever for consumers is not the choice of material when buying new, but extending the period of use: If you wear a garment twice as often, you halve the CO2e value per wear. This is followed by avoiding dryers and buying second-hand.
- A T-shirt: approx. 2–10 kg CO2e (life cycle, cradle-to-grave)
- A pair of jeans: approx. 5–24 kg CO2e
- Usage phase (washing, drying): can account for 30% or more of total emissions
- Buying second-hand saves around 62% CO2e compared to buying new, according to studies in the A-GAIN Guide
- Sources: German Environment Agency (UBA), European Environment Agency (EEA), Systain Consulting, Bundestag analysis
Immediate measure with the greatest effect: Buy less new and wear existing clothes longer.

What exactly does the carbon footprint of a garment measure?
CO2 equivalents (CO2e) combine various greenhouse gases, including CO2, methane, and nitrous oxide, into a single figure. The basis is the global warming potential of each gas over a time horizon of 100 years. For clothing, this means: All emissions along the supply chain are expressed in kg CO2e.
Life cycle assessment (LCA, life cycle assessment according to ISO 14040/14044) is the recognized method for systematically recording these emissions. It determines which processes are included in the calculation and where the system boundaries lie.
Two system boundaries are common in practice:
- Cradle-to-Gate: Records emissions from raw material extraction to the factory gate. Transport to retail and the usage phase are missing.
- Cradle-to-Grave: Includes all phases, i.e., production, transport, use (washing, drying), and disposal. This value is more meaningful for consumers.
Why do LCA figures vary so widely? Different assumptions about the period of use, washing temperature, and energy mix in the producing country also come into play.
The German Environment Agency (UBA) and the European Environment Agency (EEA) provide the institutional framework for such analyses in Germany and the EU. Organizations such as Fashion Changers and Grüne Erde translate this data into consumer-friendly recommendations.
Which life cycle phases cause the largest CO2 share?
The emissions of a garment are distributed unevenly across the individual phases. According to Systain Consulting, production and material manufacturing dominate many life cycle analyses.
- Material manufacturing and production: Spinning, weaving, and dyeing are the most emission-intensive steps. The energy mix in the producing country is decisive: A factory in a country with a high share of coal-fired electricity generates significantly more CO2e than one in a country with renewable energy. Some analyses attribute around 71% of total emissions to the production phase.
- Usage phase (washing, drying): For a long shirt, the usage phase can account for around 31% of the CO2e. If you use a tumble dryer, this share can increase significantly. According to an analysis by Polarstern Energie, green electricity and avoiding the dryer can reduce care emissions by up to 66%.
- Transport: Sea freight has a relatively small share of the total footprint. Air freight, on the other hand, significantly increases transport emissions. The Bundestag analysis on ultra-fast fashion shows that even small proportions of air freight in the logistics mix noticeably increase the footprint.
- End-of-Life: Landfilling and incineration release stored emissions. Recycling and reuse reduce this share.
Pro tip: If you buy clothes from ultra-fast fashion sources, you often pay a hidden CO2 surcharge due to air freight. Sea freight-based supply chains are significantly more climate-friendly.
What is the CO2e value of typical garments?
The following ranges are based on published LCA studies. Large ranges arise from different materials, production locations, and assumptions about the usage phase.
| Garment | Typical range (kg CO2e) | Main driver |
|---|---|---|
| T-shirt (cotton) | 2–10 kg CO2e | Production, dyeing, washing |
| Jeans (cotton) | 5–24 kg CO2e | Raw material, wet processing, use |
| Sweater (wool/synthetic) | 5–15 kg CO2e | Fiber type, energy at the factory |
| Jacket (synthetic/blended fabric) | 10–30 kg CO2e | Material usage, filling, transport |
For jeans, the Bayreuth analysis states a maximum value of 24 kg CO2e, while other methods arrive at values from 5.14 kg CO2e. The average is between 13.65 and 20 kg CO2e depending on the study.
Synthetic fibers such as polyester often have higher climate impacts due to their origin from fossil raw materials, according to the EEA. Cotton is more climate-friendly but has a high water consumption.
Pro tip: Jackets and jeans benefit particularly strongly from longer use because their high production CO2e can be distributed over many wear cycles. A sweater worn for ten years has only a fraction of the footprint per use compared to an item disposed of after two years.
How can you calculate the CO2e value per wear yourself?
The formula is simple:
CO2e per wear = total CO2e ÷ expected wear cycles
If you want to include care emissions, add them to the total CO2e:
CO2e per wear = (production CO2e + total care CO2e) ÷ wear cycles
Example calculation: Jeans
- Total CO2e of the jeans: 15 kg CO2e (conservative average from the study range)
- Assumed wear cycles: 150 (approx. 3 days per week over 1 year)
- CO2e per wear: 15 ÷ 150 = 0.10 kg CO2e per use
- With 300 wear cycles (2 years): 15 ÷ 300 = 0.05 kg CO2e per use
This shows: Doubling the period of use exactly halves the value per wear.

10 effective measures to reduce the carbon footprint of fashion
1. Buy less new
The most effective lever. Before every purchase: Do I really need it, or is an existing item sufficient?
2. Buy second-hand
Studies show savings of around 62% CO2e compared to buying new. Platforms for used clothing are widely available in Germany. Check the quality, look for damage, and realistically assess the period of use.
3. Extend the lifespan
Wear it more, care for it carefully, and repair it if necessary. A guide to repairing streetwear shows how seams, zippers, and fabric can be easily maintained.
4. Avoid dryers
The tumble dryer is the largest CO2 emitter in the usage phase. Air drying saves considerable amounts of CO2e over the life of a garment depending on the frequency of use.
5. Wash cold and choose short programs
30 °C instead of 60 °C significantly reduces energy consumption per wash. Short programs are sufficient in most cases for lightly soiled laundry.
6. Use green electricity
If you switch household electricity to green electricity, you reduce the care emissions of all laundry.
7. Material choice when buying new
Sustainable fabrics such as organic cotton and recycled fibers generally have lower production CO2e than conventional synthetics. Organic cotton and GRS-certified recycled polyester are reliable indicators.
8. Repair instead of throwing away
A torn seam or a broken button is no reason to dispose of it.
9. Use a microplastic filter when washing
Synthetic fibers release microfibers when washed. Every wash cycle releases thousands of plastic particles that enter bodies of water via wastewater. Laundry bags such as the Guppyfriend or filter attachments for the washing machine measurably reduce the microplastic input into wastewater.
10. Avoid ultra-fast fashion
According to the Bundestag analysis, models with air freight logistics have a significantly higher carbon footprint than brands with sea freight or EU production. The comparison Slow Fashion vs. Fast Fashion shows the differences concretely.
Pro tip: The combination of measure 1 (buy less) and measure 4 (no dryer) covers the majority of the personal savings potential for most households.
How can you recognize credible climate signals in clothing?
Not every green symbol on a label says anything about the actual carbon footprint. Four seals are particularly relevant in Germany and the EU:
- GOTS (Global Organic Textile Standard): Checks ecological and social criteria along the entire supply chain, from the fiber to the finished product. It is considered one of the strictest textile seals. The test number is verifiable on the GOTS website. The GOTS guide by Beachbodyz explains more about this.
- GRS (Global Recycled Standard): Certifies recycled materials and their traceability. Relevant for products made from recycled polyester or other secondary raw materials.
- OEKO-TEX Standard 100: Checks for harmful substances in the finished product but makes no statement about CO2 emissions or social standards in production.
- EU Ecolabel: Considers environmental criteria over the life cycle, including energy and water consumption. The EU Textiles Strategy establishes the EU Ecolabel as a central reference point for credible environmental communication.
Verification checklist
- Is the certificate number searchable on the seal website?
- Does the seal cover the entire supply chain or only the final product?
- Does an independent third party carry out the certification?
- Does the company provide concrete information about production locations?
Warning signs for greenwashing
- Vague terms such as "environmentally friendly" or "green" without a certificate or evidence
- Symbols that do not represent recognized standards
- CO2 neutrality promises without stating the method (avoidance vs. compensation)
- Missing information about the country of production or the supply chain
Pro tip: OEKO-TEX Standard 100 alone says nothing about the carbon footprint. If you want to buy climate-consciously, you need GOTS or GRS as an additional signal.
Can toxins be washed out of clothing?
Partially, yes. Water-soluble residues from finishing, such as certain finishing agents, can be reduced by washing multiple times. Persistent harmful substances such as PFAS (per- and polyfluoroalkyl substances) or certain heavy metals from dyeing processes, on the other hand, are difficult or impossible to wash out. OEKO-TEX Standard 100 certified clothing has already had these limit values tested in the product, which reduces the risk from the start.
Washing synthetic fibers creates a different problem: microfibers. Every wash cycle releases thousands of plastic particles that enter bodies of water via wastewater.
- Laundry bag (e.g. Guppyfriend): Catches microfibers in the bag before they enter the wastewater.
- Filter attachments for the washing machine (e.g. Filtrol or PlanetCare): Measurably reduce microplastic emissions.
- Full drum: Less friction between fibers means less fiber breakage.
- Low temperatures and short cycles: Protect the fibers while reducing energy consumption.
Recommendations from the UBA and the EEA suggest washing synthetic clothing less frequently and at low temperatures. A detailed guide to sustainable washing summarizes the most important care steps.
Pro tip: Wash new clothing once before wearing it for the first time to reduce processing residues. After that: wash as infrequently as possible, as cold as necessary.
How many wear cycles does a garment need for its production to be carbon-neutral?
"Amortization" here means: At what point is the CO2e value per wear so low that the garment is climatically acceptable? There is no fixed limit, but the calculation shows clear trends.
| Garment | Total CO2e | Wear cycles for 0.10 kg/use | Wear cycles for 0.05 kg/use |
|---|---|---|---|
| T-shirt | 5 kg | 50 | 100 |
| Jeans | 15 kg | 150 | 300 |
| Sweater | 10 kg | 100 | 150 |
| Jacket | 20 kg | 150 | 300 |
Decision rule: Buy, repair, or second-hand?
- New purchase: Only if the piece is worn regularly for at least 2–3 years and a seal certifies the production quality.
- Repair: Almost always worth it, as long as the repair costs are below the new price and the piece still has many wear cycles left.
- Second-hand: Best CO2e balance per wear, because the production emissions are spread over more total uses.
Material blends make recycling more difficult at the end of their life.
Beachbodyz communicates the longevity of its products as a concrete climate benefit: Organic cotton and robust cuts are designed to withstand many wear cycles, thereby keeping the CO2e value per use low.
How Beachbodyz reduces the footprint of its streetwear
Beachbodyz is a German streetwear brand focused on sustainable production in the EU. The brand's measures can be directly traced back to the levers described in this article.
- Material choice: Organic cotton and GRS-certified recycled polyester. Organic cotton avoids synthetic pesticides and generally has a lower production CO2e than conventional cotton.
- Production in the EU: Shorter transport routes, stricter environmental and social standards, no air freight risk due to intercontinental logistics.
- Long-lasting cuts: Oversized fits made from robust materials are designed for many wear cycles. This directly reduces the CO2e per use.
- Climate-neutral shipping: Offsetting shipping emissions for direct shipping to customers in Germany and Central Europe.
Longevity is not a marketing promise, but a measurable CO2e value: A garment that is worn 300 times instead of 150 times halves its footprint per use.
The Essential Oversize Sweatshirt made from organic cotton and the Identity Jogger Shorts are examples of products where material choice, production, and cut are designed for maximum usage duration. All information is based on company data from Beachbodyz.
Pro tip: When buying sustainable streetwear: Check the GOTS number on the product page and pay attention to information about the country of production. "Made in EU" with GOTS is a more reliable signal than an unspecific "eco" label without proof.
What research really says and what many people misunderstand
Most guides on the CO2 footprint of clothing focus on purchasing: organic cotton instead of polyester, a seal instead of no seal. This is not wrong, but it is too narrow.
Someone who buys a GOTS-certified T-shirt but washes it at 60 °C and then puts it in the dryer quickly uses up the advantage of cleaner production. The material choice at purchase is a one-time effect. Washing behavior repeats a hundred times.
The second-hand effect is even more underestimated. And yet, second-hand is only a minor point in many sustainability guides.
What really counts is the combination: buy less, wear longer, wash cold, no dryer. Anyone who implements these four points has done more than someone who exclusively relies on expensive certified new goods and discards them after one season. Certificates are important for production quality. But they do not replace behavior after purchase.
Sustainable streetwear that lasts longer than one season
Anyone who wants to reduce the CO2 footprint of their clothing needs pieces that can withstand many wear cycles. Beachbodyz produces streetwear from organic cotton and recycled polyester, fairly manufactured in the EU. The cuts are designed for longevity: no pilling after three washes, no fit problems after one year.
The Essential Oversize Sweatshirt and the Identity Jogger Shorts are concrete examples: organic cotton, EU production, cuts that work for years. Anyone who buys a piece now and wears it 300 times will be far below the average CO2e per use of a fast-fashion piece with 50 wear cycles. The Oversize Hoodie made from recycled materials is also available in the shop. All products are available directly at Beachbodyz.

FAQ
How much CO2 does a T-shirt cause?
A cotton T-shirt causes approximately 2–10 kg of CO2e over its entire life cycle (cradle-to-grave), depending on the place of production and usage behavior. Cradle-to-gate values are partly around 1.37 kg of CO2e, but do not include use and disposal.
What is the CO2 footprint of a pair of jeans?
Analyses cite ranges of approximately 5.14 to 24 kg of CO2e per pair of jeans; average values range between 13 and 20 kg of CO2e depending on the study. The actual value depends heavily on the place of production, wet processing, and washing behavior.
Can toxins be washed out of clothing?
Water-soluble processing residues can be partially reduced by washing multiple times. Persistent pollutants such as PFAS or heavy metals from dyeing processes, on the other hand, are hardly washable; clothing certified with OEKO-TEX Standard 100 has already had these limits tested in the product.
What is the total CO2 consumption in clothing production?
The exact share varies depending on the system boundary and product type.
What does buying second-hand really bring climatically?
Second-hand is thus one of the most effective individual levers for consumers, because the production emissions are spread over more total uses.
