Citizens of Humanity Group has joined forces with French biotech pioneer Pili and Turkish denim mill, Orta, to unveil the Eco-Indigo collection in a groundbreaking step towards redefining denim’s sustainability. This collaboration introduces a revolutionary bio-based indigo dye, an innovation that slashes CO2 emissions by 50% compared to traditional petroleum-based dyes. The Eco-Indigo collection, debuting in Spring 2025 under the Citizens of Humanity and AGOLDE brands, seamlessly integrates Pili’s bio-based dye with Orta’s advanced manufacturing expertise and Citizens of Humanity’s Regenerative Cotton Program. This continues the group’s commitment to making denim the cornerstone of every collection accompanied by luxury design pieces for the contemporary wardrobe. Citizens of Humanity Group CEO Amy Williams leads the shared vision for a regenerative future, demonstrating that true innovation stems from collaboration, commitment and action. Read on for Williams’ insights into the collection.
Sustainability is such a buzzword in fashion right now. What does it mean to Citizens of Humanity and AGOLDE, and how do you make it part of your brand’s identity in a genuine way?
Strong leadership is key, as is identifying and focusing on areas where we can make the greatest impact. Collaboration and open communication are essential to achieving meaningful progress. Responsible stewardship, transparency, and genuine action are at the heart of our approach. We prioritize investments in scalable innovations across all our brands rather than just one-off capsules and stay true to our commitments, avoiding any greenwashing.
Denim is such a universal wardrobe staple. How does this collection honor that tradition while moving it into the future?
The product in this collection doesn’t look any different—in fact, the quality is even better. By using regenerative cotton and incorporating Eco-Indigo dye, we’ve created a product that respects denim’s timeless appeal while making significant strides toward making our environment a better place through what we produce.
Denim often tells a story over time through its wear. How do you see the story of this collection being different, given its sustainable roots?
This collection embodies a blend of history and innovation. Wearing it provides instant gratification, knowing you’re investing in longevity, in groundbreaking science, and in the future.
Sustainability in fashion often comes with a sense of compromise. What’s one thing you’d like people to know about this collection that challenges that idea?
Achieving sustainability doesn’t happen overnight. It is a process that requires years of collaboration and commitment with the right partners and a shared vision to make it happen. We have decided to absorb the investment costs so customers can experience the benefits of these innovations without being on the receiving end of increased prices.
What do you think this innovation says about the future of denim and fashion? Do you feel this is the start of a new chapter for the industry?
It’s a clear signal that the industry is evolving. This year we’ve seen a greater focus on collaboration, transparency, community and non-competitive partnerships as part of the regular conversations. Brands and retailers are supporting innovation and demonstrating genuine commitment to sustainability. An understanding that sharing, leveraging information, supporting innovators, growers, and change makers is key. We’re seeing more companies invest in innovative sustainable suppliers or step up to demonstrate interest and demand. European regulations, and commitments to support innovation, technical solutions, investments and testing have all become part of the regular activities for brands and retailers. This moment marks the beginning of a new chapter, where sustainable practices are integral to the fashion industry’s future.
This partnership represents a pivotal shift for the denim industry, showcasing how sustainability can align with high performance and style. From cultivating regenerative cotton to implementing advanced bio-dyeing techniques, it’s a journey toward reducing fashion’s environmental impact while celebrating the timeless appeal of denim.
