Indigo To Eco: The Carbon Closet's Top 10 Responsible Denim Brands

Denim. It’s arguably the most essential fabric in every wardrobe.

From everyday jeans to hardworking overalls, we all own — and regularly wear — these blue basics.
But at what cost?

Denim, although ever present in our closets, has one of the largest environmental impacts of all clothing items. From resource heavy growth and production, to toxic chemical dyes and treatments, denim is then responsible for 91% of fast-fashions carbon footprint, and can emit 32.5kg of CO2 from just one pair of jeans!

This is why The Carbon Closet is dedicated to providing you with only the most responsible and ethical fashion brands. From statement pieces to wardrobe staples, we have thousands of products on our website that will suit your every need, including an extensive range of unique and eco-friendly denim. To read more into what effects denim has on the planet, take a look at our Denim Blog, but for now, let's focus on the best planet-loving brands that actually deserve your attention...

Here are The Carbon Closet’s top 10 recommended denim brands for a chic yet conscious closet.

This Aligne Midi dress not only adds a unique piece to your wardrobe, but uses 99% organic cotton for a fashionable and eco-friendly frock! With many other quality dresses in stock, The Carbon Closet recommends a browse for more responsible denim by Aligne on our website.

Looking for something more practical? These Utility Dungarees by Nudie Jeans are 80% organic cotton. Not only do Nudie Jeans track every step of production and transport alongside their products on their website, but they also offer a repair and recycling programme! This is a brand for the future of fashion!

We couldn't make you wait long for a classic pair of jeans. The White Company's Organic Cotton Jeans use an eco-wash process and sustainable technology in production to minimise waste and pollution. This brand values "Timeless Style, not fast-fashion" and "Quality, not quantity" and The Carbon Closet most definitely agrees!

Pangaia's Mid-Wash Nettle Denim Jacket is not lying when they mention "nettle". alongside 82% cotton, the remainder of the jacket is sourced from Ramie, a wild Himalayan Nettle, and then treated with natural Peppermint (PPRMINT^tm). Pangaia is definitely worth a visit for fashion as fresh in friendliness as it is looks!

Kings of Indigo are giving more than just indigo jeans. The Carbon Closet loves these 100% organic cotton Liora Shorts, not only for their superior style, but also for their 3-year worldwide repair warranty and their product journey available on their page! Transparency in fashion is a triumph for fashion!

Some statement pieces now, and where better to begin than with Seventy + Mochi. These Marie Jeans are bound to get those compliments rolling in; and whilst we're on the subject, The Carbon Closet would like to compliment Seventy + Mochi for their dedication to conscious denim production and product care guides on their website!

We're not finished with those unique show-stopping pieces yet! Here is Concepts by CC, a bespoke, upcycling brand that takes pre-loved vintage garments, and transforms them into something fun and one-of-a-kind, such as this Denim Jacket. Each piece has a number rather than a name because no two items will be the same!

Introducing Fanfare! These distinctive items are crafted from recycled bottles and recycled or organic cotton. These gorgeous Mom Jeans, are made to order and encourage slow, circular fashion. FanFare has won many awards for their ethical sourcing and zero waste approach- So from us at The Carbon Closet: Congratulations!
