Unlocking the Future of Carbon Markets: Key Insights from Carbonmark’s Webinar on On-chain Carbon Credits
In an era where transparency and accountability are crucial for meaningful climate action, Carbonmark is leading the way in transforming carbon markets. The recent webinar, “On-Chain Carbon Credits: A New Era of Transparency and Trust,” brought together industry pioneers to explore how blockchain redefines the voluntary carbon market (VCM), making it more transparent, efficient, and impactful.
Blockchain: The Backbone of Transparent Carbon Markets
Andrew Bonneau from Carbonmark set the stage by highlighting the transformative role of blockchain and smart contracts in the VCM. At its core, blockchain creates a transparent and immutable record of carbon credit issuance, transactions, and retirements. This transparency is not just a technical feature; it’s the answer to a critical market demand—buyers want proof that the carbon credits they purchase lead to real, measurable, and additional emissions reductions.
Andrew outlined how blockchain eliminates intermediaries, reduces costs, and speeds up transactions, making the entire process more efficient. By using smart contracts, Carbonmark enables the automation of carbon credit purchases and retirements, streamlining what has traditionally been a cumbersome process. This automation also allows for creative market solutions, like bundling different types of credits or fractionalizing them for smaller-scale buyers.
“Blockchain provides a single source of truth in a market that thrives on credibility and transparency,” Andrew emphasized, framing the technology as essential for scaling carbon markets responsibly.
Stories from the Fields: Real-World Applications of Blockchain in Carbon Projects
The webinar featured two forward-thinking project developers—Limenet and One Earth Fund—who are using blockchain to bring transparency and trust to their carbon removal efforts.
Limenet: Accelerating Nature-Based Carbon Removal in Italy
Stefano Cappello, founder and CEO of Limenet, shared the remarkable journey of turning a simple idea into Italy’s first industrial facility designed to remove carbon through an enhanced geological process. Inspired by nature’s own carbon cycle, Limenet uses limestone to capture CO₂ and store it as calcium bicarbonate in the ocean, addressing both atmospheric carbon and ocean acidification.
Stefano’s passion was palpable as he recounted starting Limenet in his grandmother’s garage, eventually scaling it into an industrial operation. The technology, while rooted in natural processes, leverages modern engineering to accelerate carbon removal, achieving results that would naturally take thousands of years.
Blockchain plays a critical role in Limenet’s operations by enabling Digital Monitoring, Reporting, and Verification (dMRV). This real-time data tracking not only validates carbon removal but also ensures stakeholders can verify the process independently.
“Our goal is to remove one million tons of CO₂ by 2030,” Stefano shared. “Blockchain ensures we can scale with transparency and trust, showing exactly how much carbon is being removed and how it benefits marine ecosystems.”
One Earth Fund: Turning Food Waste into Carbon Credits
Switching gears from oceanic solutions to land-based impact, Gordon Hilbun from One Earth Fund showcased how composting food waste can be a powerful tool in the fight against climate change. One Earth Fund partners with composting facilities across the U.S., turning food waste that would otherwise decompose in landfills—releasing harmful methane—into nutrient-rich compost that enhances soil health and carbon sequestration.
What makes One Earth Fund’s approach stand out is its simplicity. Composting is an age-old practice, but by integrating blockchain, they bring modern accountability to the process. Every stage—from the diversion of food waste to the creation of compost—is tracked in real time, ensuring that every carbon credit issued is verifiable and backed by hard data.
“We needed a platform that could simplify the process and maintain transparency, and Carbonmark provided exactly that,” Gordon noted. “It’s not just about reducing emissions—it’s about creating trust in the credits we issue.”
Carbonmark: Bridging Innovation and Market Access
At the heart of the webinar was Carbonmark’s commitment to simplifying the path from project development to market access. By acting as both a credit issuance platform and a marketplace, Carbonmark offers an end-to-end solution for carbon project developers. This integrated approach shortens time-to-market and ensures that even projects using novel carbon removal methodologies can find buyers.
Through smart contract technology and blockchain-based tracking, Carbonmark ensures that all transactions are transparent, secure, and verifiable. This makes it easier for buyers to trust the credits they purchase and for project developers to get the funding they need to scale their impact.
Andrew also highlighted Carbonmark’s efforts to make the process more accessible for innovative projects that might struggle to meet the rigid criteria of traditional registries. Whether it’s a novel carbon removal technology or a smaller-scale community project, Carbonmark provides the flexibility and transparency these developers need to succeed.
“By opening up market access and providing real-time data tracking, we’re helping projects scale faster while maintaining the highest levels of integrity,” Andrew explained.
Key Takeaways: Why Blockchain is a Game-Changer for Carbon Markets
The webinar reinforced that blockchain isn’t just a buzzword—it’s a practical tool for solving some of the most pressing issues in carbon markets. From ensuring the credibility of carbon credits to simplifying complex transactions, blockchain lays the foundation for a more transparent and efficient market.
Limenet and One Earth Fund demonstrated that no matter the approach—whether it’s leveraging natural oceanic processes or rethinking food waste management—blockchain can provide the transparency, efficiency, and scalability that today’s carbon markets demand.
The path forward is clear: as more project developers integrate blockchain into their operations, carbon markets can scale with greater trust, efficiency, and impact.
