Jeans and Their Impact on the Environment

Jeans are one of the most iconic and widely used garments in the world with more than 3 billion jeans being produced and sold every year. They are durable, versatile, and timeless. But behind their everyday use lies a production process with significant environmental and human impact.

From cotton farming to dyeing and finishing, the lifecycle of a pair of jeans requires large amounts of water, energy, and chemicals. Producing one pair of the iconic 501® Levi Strauss jeans consumes 3,781 litres of waters and causes 33.4 kg of Co2 emissions throughout its lifetime, according to Levi Strauss itself. 

The most efficient production methods still require 1,000 litres of water per pair of jeans, whereas the least efficient methods demand 10,000 litres for a single pair of jeans. Mind-boggling, isn't it? 

It’s a system built for scale - but not necessarily for sustainability.

The Hidden Cost of Denim Production

The production of denim begins with cotton, a resource-intensive crop that often requires substantial water and pesticide use. From there, the fabric undergoes multiple stages of processing, including spinning, weaving, dyeing, and finishing.

One of the most impactful steps is dyeing. Traditional denim is dyed with indigo, and the process often involves chemicals that can be harmful if not handled properly. In many parts of the world, wastewater from dyeing processes is released into rivers, affecting both ecosystems and local communities.

Beyond environmental concerns, there are also human implications. Workers in textile production may be exposed to hazardous chemicals and unsafe conditions, especially in fast fashion supply chains where cost and speed are prioritized.

Overall, the production of jeans is resource-heavy and polluting - especially when driven by overproduction and short product lifecycles.

The Strength and Story of Denim

Despite its impact, denim has one key advantage: durability.

Denim is a strong fabric, typically made from cotton and sometimes blended with polyester or elastane for stretch. It was originally designed as workwear - built to last through tough conditions. Over time, jeans have evolved into a global fashion staple, but their core quality remains the same: they are made to endure.

Every pair of jeans also tells a story. Fades, marks, and wear patterns reflect how the garment has been used - making each piece unique over time.

This durability and individuality are important. Because if a product is made to last, it should be used to its full potential.

 

Why We Use Jeans As They Are

At VAER, we work with existing denim instead of breaking it down and recreating new materials.

When textiles are recycled mechanically or chemically, the fibres are often shortened or weakened in the process. This means that the new material can lose some of the strength and durability that the original fabric had.

By using jeans as they are already made, we preserve those qualities. We extend the life of a material that has already required significant resources to produce - without putting it through another energy-intensive process.

In this way, upcycling becomes not just about reducing waste, but about respecting the value of what already exists.

 

Rethinking Value in Fashion

If we consider the full impact of denim production, it becomes clear that jeans are not just simple, everyday items. They are resource-heavy products with a long and complex journey behind them.

This raises an important question: how can we make better use of what has already been produced?

Extending the life of garments, repairing them, reusing them, and rethinking how we value materials are all part of the answer. Instead of constantly producing new textiles, there is an opportunity to work with what is already available - and to see it not as waste, but as a resource.
