C2C Products Innovation Institute: Verifying Circular Action

In the face of today’s climate and health crises, coupled with a growing shift toward digitization and AI-driven product discovery, many brands want to take the leap into designing products that are good for people and planet. 

But navigating the switch to circularity is a complicated matter that requires clear, actionable guidance through a strong framework that can verify if they’re hitting the mark or falling short.

We spoke with Elwyn Grainger-Jones, CEO of the Cradle to Cradle Products Innovation Institute, about how this organization is setting the benchmark for tangible circular integration through its measurable, science-based certification program.

What inspired your founders to start your organization and engage in developing circular economy certifications?

Our organization was born directly from the vision of our co‑founders, William McDonough and Dr. Michael Braungart, who wrote Cradle to Cradle: Remaking the Way We Make Things, 25 years ago. Their book introduced a transformative approach to designing products for human and environmental health, and it quickly sparked interest from companies eager to apply its principles.

As more organizations asked for practical guidance, the founders recognized the need for a clear, actionable framework. They created a product standard rooted in the ideas of the book, turning a design philosophy into a measurable, science‑based certification. That became the foundation of our work and continues to guide our mission today.

Why are certifications important for advancing the circular economy, and how does your organization help set the standard for integrating circularity?

Certifications turn circularity from ambition into accountable, verifiable performance. As the standard-setting body behind Cradle to Cradle Certified®, we, as the Cradle to Cradle Products Innovation Institute, helped launch the modern circularity movement, building on the Cradle to Cradle design philosophy that continues to guide industry practice.

We set the benchmark for integrating circularity through rigorous product requirements and third‑party verification, including a Circularity Data Report that makes circular data and cycling instructions transparent and available to all. Safe materials are the foundation of a truly circular economy, which makes verification of material health indispensable. It is simply the only reliable way to ensure non‑toxic substances keep circulating without harm.

To ensure progress, we created a continuous improvement tool and recertification pathway that require companies to demonstrate measurable advancements over time, transforming circular design into a sustained journey rather than a one‑off label.

What do you consider to be your biggest success in advancing circular product development? Can you share any stories of impact your work has had that have surprised you?

Our biggest success has been transforming circularity from a concept into a practical, measurable reality through the Cradle to Cradle Certified® framework. Over the past decade, we have enabled thousands of companies to design products that are healthy, circular, and verified, spanning sectors from textiles and apparel to building materials and electronics. 

What surprises us most is the ripple effect: brands initially seeking compliance often become champions of innovation. For example, partnerships in fashion have led to fibre-to-fibre recycling breakthroughs and trims designed for easy disassembly—solutions that seemed aspirational just a few years ago. Seeing these ideas scale globally, influencing procurement policies, and inspiring entire value chains is proof that rigorous standards can drive systemic change.

What are some of the challenges you typically face working to set the global standard and advance circular product development?

Setting a global standard for circular products is both essential and complex. One major challenge is harmonizing diverse regulatory frameworks and market expectations across regions while maintaining scientific rigour and credibility. 

We also face the tension between ambition and feasibility, pushing innovation without creating barriers for companies at different stages of their sustainability journey. 

Another hurdle is data: ensuring transparency and comparability of circularity metrics requires robust systems and collaboration across supply chains. 

Finally, scaling adoption demands cultural change; moving industries from linear habits to circular thinking takes time, investment, and trust.

What is the role of digitization in the world of certifications, and how is your organization tackling this for the Cradle to Cradle Certified® certification program?

Digitization plays a transformative role in making certifications visible, trusted, and actionable. As product discovery becomes increasingly AI‑driven, there is a major opportunity to embed sustainability intelligence directly into search and purchasing decisions. Early research already shows that independent trust indicators (like third‑party certifications) rank far more prominently in AI‑powered product searches, creating new incentives for companies to improve their product design and transparency.

A good example of this is Amazon’s Climate Pledge Friendly program, which pre‑vets Cradle to Cradle Certified® alongside other selected certifications. By integrating these signals directly into product search results and dedicated category pages, listed items have seen an average 12%+ sales uplift, with some brands experiencing even higher boosts. This demonstrates the power of making credible sustainability information digitally accessible and reinforces why companies are increasingly motivated to redesign products for circularity.

For the Cradle to Cradle Certified® program, we are strengthening our digital foundations so the certification can serve as a reliable, machine‑readable signal in online and AI‑supported environments. At the same time, we are digitizing our entire certification process to reduce duplication, speed up reviews, and make circular product development more accessible for companies and assessors. This ensures that credible circularity signals are not only easier to find but also easier for brands to act upon.

Looking ahead, what are your hopes for the circular economy over the next decade, and how do you envision contributing to this vision? How can other organizations get on board?

According to the Circularity Gap Report 2025, only 6.9% of the global economy is circular, a figure that has remained stubbornly low despite years of awareness‑raising and policy development. Over the next decade, we hope to see circular design become a fundamental expectation in product development. Approaches like Cradle to Cradle Certified® play a key role by offering a clear, science‑based pathway for companies to create products that are made for both people and the planet.

Our contribution is to scale this transition by supporting businesses in developing products that meet these rigorous standards. By 2030, we aim to double the number of healthy and circular products on the market. Our ultimate goal is to make circular design the new normal through transparent criteria, credible verification, and practical support that helps companies turn circularity from a concept into reality. When businesses understand the economic, reputational, and compliance benefits—and have practical tools to act—circularity becomes a strategic advantage rather than a challenge.
