levis is a pioneer in sustainable denim production using innovative methods to reduce water use

If there’s one fashion fabric that’s a worldwide wardrobe staple, it’s denim. No matter the form you own it in—whether jeans and a tee is your everyday uniform, or even if you’ve traded your denim in for loungewear during the pandemic—no-one can deny the iconic global status of this blue woven material.

But here’s something you may not know: the production of denim has a big environmental impact. Whether your denim is raw or washed, it takes a massive amount of resources and chemicals—including pesticides, dyes, land, labour and water—to go from cotton crops to your favourite flared cut. Did you know it takes a whopping 20,000 litres of water to produce just 1kg of cotton? And denim is made from a lot of cotton.

The good news is that over the last few years, innovations have come about to help make denim production more sustainable and less resource-intensive. What’s more, there’s now a number of international and emerging designers that consciously make their denim in a greener way. Read on for the best in sustainable denim brands, so the next time you’re looking to replace your old jeans or denim jacket, you can support a label that prioritises our planet.
