Beyond Sustainability: How Cambium Carbon Built a Business Case for Urban Wood

Most sustainability startups lead with ESG metrics. But in a recent episode of Category Visionaries, Ben Christensen revealed how Cambium Carbon built a business case around urban wood waste that focuses on fundamental business value rather than just environmental impact.

Finding Value in Waste

The numbers tell a compelling story: “It’s 46 million tons a year in the US. There’s more wood that comes down in our cities every year that’s salvageable than our national forests,” Ben explains. “We pay over a billion dollars a year as a country to get rid of.” This waste represents a potential “$50 billion in value if we captured all that material.”

This isn’t just an environmental problem – it’s a massive business inefficiency hiding in plain sight.

Beyond Carbon Credits

While many climate tech companies focus on creating new markets and trading platforms, Ben saw an opportunity in solving physical problems: “There’s a lot of effort into enabling solutions and a gap in actual solutions… there’s a lot of new platforms that are trying to create the market conditions… But there was a real gap in actual solutions that were going to actively be dealing with atoms and not just bits.”

Building Value Through Transparency

Instead of relying on certification schemes, Cambium Carbon built technology that makes supply chains visible. “One of the biggest challenges within sustainability always is clarity and transparency,” Ben explains. Their approach eliminates the need for third-party validation: “You need a certifier when you have a third party coming in, because you don’t actually know what’s happening in the supply chain. For us, we’re able to help them see with total transparency, each step of the process.”

Creating Local Economic Value

Their model doesn’t just reduce waste – it creates value for local economies. As Ben describes, they focus on “helping to keep waste out of our waste streams, and then also really connecting local economies and local jobs back into the new green economy.”

This approach helps transform what might be seen as a cost center (waste disposal) into a revenue opportunity for local processors while reducing shipping costs for buyers.

Turning Uniqueness into an Asset

Rather than trying to standardize materials like traditional suppliers, Cambium Carbon embraces the unique characteristics of urban wood: “We just live in this world where so many things are optimized to be the same… We really believe in sort of rethinking that and rethinking the uniqueness of products, the stories behind products.”

This strategy transforms what might be seen as a liability (non-standardized materials) into a selling point. As Ben notes, “When we all are in our houses, we don’t talk about something that’s there that is just the same as everybody else. We talk about the thing that is unique or has a story.”

Building for Scale

Looking ahead, their vision extends beyond just creating a more efficient marketplace: “Our vision is to make it easy for any large company that uses materials to be able to source them in a way that is carbon smart.” This approach has attracted major customers like Patagonia, National Geographic, and Microsoft.

For B2B founders selling sustainability solutions, Cambium Carbon’s approach offers several key lessons:

1. Focus on fundamental business inefficiencies
2. Build value through transparency rather than certification
3. Transform industry “problems” into unique selling points
4. Create value for all stakeholders in the supply chain

By focusing on creating tangible business value rather than just environmental impact, Cambium Carbon has built a model that makes sustainability a natural outcome of better business practices rather than just a compliance exercise.
