There's nothing like adding a new pair of sustainable jeans for a quick wardrobe update.

If you’re looking to shop the best, then investing in a decent pair from one of many sustainable fashion brands is a good place to start.

Jeans are a solid staple in our capsule wardrobe, and although they may not be as throwaway as other fast fashion garms, it doesn’t mean they aren’t damaging to the planet. In fact, Denim brand Levi Strauss estimates a pair of its signature 501 jeans will produce the equivalent of 33.4 kg of carbon dioxide equivalent (CO2 eq) across its entire lifespan—about the same as driving 69 miles in the average US car. These emissions are from a combination of production, packaging, transport, and consumer use.

The UN also estimates that a single pair of jeans requires one kilo of cotton and producing that one kilo uses around 10,000 liters of water—enough drinking water for one person over 10 years. And we’re all guilty of having more than one pair in our closets. Luckily, many brands—including the likes of Everlane, DL1961, and all your faves—have been making moves to make jeans more planet-friendly.

What makes jeans sustainable?

Everything from production to transport has its effect on the planet. “Sustainable fashion to me is a more considered approach to what I’m consuming—so really abiding by the principles of buying less, buying better, and sharing more,” says Eshita Kabra Davies, founder of By Rotation, a peer-to-peer rental app. So we, as consumers, can help by investing in high-quality jeans that last, holding on to them for longer, and wearing them more often. If we kept our clothes (and continued to wear them) for just nine months longer, it could reduce their environmental impact by 22 percent, according to a report by the recycling charity Waste and Resources Action Programme (WRAP).

What to look for when shopping for sustainable jeans

Look for transparency from the brand about how each pair is produced—from the use of dyes and chemicals to shipping and factory conditions. Be wary of ‘greenwashing’ and anything too brief. Brands such as Reformation and DL1961 state the sustainability impact of each pair of jeans on its website so you know exactly what you’re in for. 

When it comes to fabrics, look for materials such as Tencel, Organic Cotton, and recycled or upcycled methods. “Buy clothes made from sustainable fibers. Our goal is to create clothes that reduce the environmental impact. That’s why we keep our supply chain short and build long-lasting relations with our suppliers based on trust and communication. Our clothes are designed to last and to be worn time after time. We use certified fabrics (Oeko-Tex, GOTS, Lenzing) and next year we will go even further,” explains Justyna Przygonska, Co-Founder of The Odder Side, a sustainable fashion brand based in Poland.
