The Environmental Impact of Clothing: Textile Industry CO₂ Emissions Explained

We rarely stop to think about it, but the clothes you wear every day have a major impact on the environment. From the production of raw materials to transport and waste processing, the textile industry has grown into one of the most polluting sectors worldwide.

But just how large is that impact? More importantly, what does it mean for the choices we make every day? In this blog, we take a closer look at the world of textiles and CO₂ emissions, and you will discover why conscious choices matter more than ever.

How large are the CO2 emissions of the textile industry?

The figures speak for themselves. The textile industry is responsible for a significant share of global greenhouse gas emissions.

• Globally, the sector accounts for around 4% to 8% of total CO₂ emissions
• Some estimates even point to more than 8% or higher, depending on which elements are included
• In absolute terms, this amounts to around 1.2 billion tonnes of CO₂ per year

To put that into perspective: emissions from the textile industry are greater than those from international aviation and shipping combined.

That makes clothing more than just a consumer product. It is also an important factor in the climate crisis.

Why clothing has such a large impact

The high CO₂ emissions of the textile industry are not caused by one single factor, but by a combination of processes that all require energy and raw materials.

1. Raw materials and production

It all starts with raw materials. Cotton, wool and synthetic fibres such as polyester require large amounts of water, land and energy. For synthetic fabrics, there is an extra issue: they are made from fossil fuels. This means that every polyester fibre directly contributes to CO₂ emissions.

In addition, the production process is intensive. Spinning, weaving, dyeing and finishing fabrics consume enormous amounts of energy, often derived from fossil sources.

2. Dyeing and finishing

A large share of emissions comes from dyeing and treating fabrics. This process is not only energy-intensive, but also causes water pollution. In fact, around 20% of global water pollution is caused by the textile industry, particularly through dyeing processes (European Parliament).

3. Transport and logistics

Clothing is often produced and transported around the world. Raw materials from one country, production in another, and sales on yet another continent. Although transport is not the biggest factor, it still contributes to total CO₂ emissions, especially when it comes to fast delivery and air freight.

4. Overconsumption and fast fashion

Perhaps the biggest driver behind these emissions is our consumption behaviour.

In recent years, we have started buying more clothing and replacing it more quickly. The average consumer now buys up to 60% more clothing than 15 years ago, but wears each item for a shorter period of time.

This creates constant demand for new production, and therefore more emissions.

5. Waste and lifespan

The impact does not stop when you throw clothing away. A large proportion of all garments ends up in landfill or is incinerated. Only a small percentage is actually recycled into new clothing.

In addition, the breakdown or incineration of textiles releases CO₂ and other harmful substances all over again.

Why this problem is bigger than you think

What makes the textile industry especially complex is that its impact is often invisible to the consumer. You do not see how much water is needed for a T-shirt. You do not notice how much CO₂ is released during production. You do not directly feel the consequences of fast fashion.

Yet on a global scale, the effect is enormous. The sector is also still growing. Global textile production continues to rise and is expected to increase further in the coming years. Without change, this automatically means more emissions, more waste and more pressure on the environment.

The role of materials: where the real difference is made

One of the most important factors within the textile industry is material choice. Not all fabrics are equal. Some materials have a much greater impact than others.

• Cotton requires a great deal of water and agricultural land
• Polyester depends on fossil fuels
• Bamboo viscose requires chemical processing

This is where innovation creates opportunities.

Materials such as TENCEL™ are produced from wood pulp sourced from sustainably managed forests, using a closed-loop process in which raw materials are largely reused. This significantly lowers environmental impact compared with traditional fabrics.

Buy less, choose better

The solution does not lie with producers alone, but also with consumers. It is not necessarily about owning fewer clothes, but about making better choices. Clothing that lasts longer, feels more comfortable and is produced more sustainably ultimately leads to less impact. Less replacement means less production and therefore fewer emissions.

This ties in with a broader movement away from fast fashion and towards quality and sustainability.

What does this mean for your underwear?

Underwear may not be the first thing that comes to mind when you think about sustainability, but this is exactly where you can make a difference. You wear it every day, wash it frequently and replace it regularly. That makes it an important part of your clothing footprint.

By choosing underwear that:

• lasts longer
• performs better
• is produced more sustainably

you indirectly reduce your own footprint.

The vision of Undiemeister

At Undiemeister, we believe that comfort and sustainability should go hand in hand.

That is why we consciously choose materials such as TENCEL™ and Mellowood, which not only feel better, but also have a lower impact on the environment. The aim is simple: underwear that is not only good for you, but also better for the world.

Frequently asked questions about textiles and CO2 emissions

1. How much CO2 does the clothing industry emit?

The textile industry is responsible for around 4% to 8% of global CO₂ emissions.

2. Why is clothing so polluting?

Because of the combination of raw material production, energy use, transport and overconsumption.

3. Which is the bigger polluter: cotton or polyester?

Both have an impact. Cotton because of water use, polyester because of fossil raw materials and CO₂ emissions.

4. What can you do yourself?

Choose sustainable materials, buy less and invest in quality that lasts longer.

Small choices, big impact

The textile industry is undoubtedly one of the biggest CO₂ polluters in the world. But that also means there are enormous opportunities for improvement. By making more conscious choices, opting for better materials, higher quality and less waste, everyone can contribute to a more sustainable future.

It starts with the basics. Literally.
