Thallo Announces Two-Way Bridge Integration with Registry

Thallo’s second registry integration will offer customers access to the first-ever tokenized carbon removal credits from a registry

London (7 February 2023) – Pioneering climate tech Thallo today announced a technical integration with carbon removal registry, expanding the range of credits that can be brought onto the Thallo platform to include Puro Standard-issued credits for engineered carbon removal processes. is the second registry that will be connected to Thallo’s two-way carbon bridge, a piece of technical infrastructure that allows for the tokenization of carbon credits securely from a registry onto a public blockchain. The addition of credits complements Thallo’s existing registry integration with BioCarbon Registry, which primarily issues nature-based carbon avoidance credits.

“Increasingly, corporate customers are looking for high-quality tech-based carbon removals to meet their sustainability ambitions, and with the integration, we are making it easier and more transparent than ever to buy these credits,” said Ryan Gledhill, Thallo co-founder and CEO. “We’re proud to deploy our technical infrastructure to service this critical market need.” 

“ was founded to fill unmet needs in the voluntary carbon market, such as the lack of high-quality durable carbon removal credits, and integrations such as the one with Thallo is yet another way we are remaining at the cutting edge of innovation to grow the market,” said Antti Vihavainen, CEO of “Quality remains our top priority, and we are impressed by the level of data integrity included in Thallo’s two-way bridge.”

Thallo has already launched its Bridging-as-a-Service offering, which allows customers to use Thallo’s two-way bridge to access tokenized carbon credits. The full Thallo carbon exchange, which will connect carbon credit suppliers directly with the end buyers, will be launched later this year.

Developed by, the Puro Standard is the world’s first carbon standard for engineered carbon removal. It consists of high-quality removal methodologies that credit net removal rather than reduced or avoided emissions, which the Science-Based Targets Initiative (SBTi) recommends for companies seeking to cover residual emissions on the path to net zero. CO2 Removal Certificates, CORCS, are issued per metric ton of CO2 removed and the activity is verified by independent third-party auditors.’s credit inventory comprises several project methodologies, including biochar, woody biomass burial and geologically removed carbon, and recently became the first organization to issue a standard for enhanced rock weathering carbon removals. The company was acquired by Nasdaq in 2021 and together they are growing the carbon removal market.

About is the world’s leading carbon crediting platform for carbon removal. Our mission is to mobilize the economy to reward carbon net-negative emissions. We do this by helping voluntary corporate buyers accelerate carbon dioxide removal at an industrial global scale.

Through the Puro Standard we create carbon credit methodologies for processes that remove carbon dioxide from the atmosphere for at least 100 years. We then certify suppliers that run those processes and issue digital tradable CO2 Removal Certificates (CORCs) into the public Puro Registry per metric ton of carbon dioxide removed. CORCs are then purchased directly from suppliers or via sales channel partners by ambitious corporations, like our customers Microsoft, Shopify, and Zurich Insurance, to help reverse climate change and neutralize their residual carbon emissions. With Puro Accelerate, our program to scale the carbon removal ecosystem, we assist suppliers who require financing to launch or expand operations to secure funding through CORC advance market commitments and prepayments.
In 2021, Nasdaq acquired a majority stake in and together we are driving forward the carbon removal industry, enabling new revenue streams to accelerate its growth. Visit us at or on LinkedIn and Twitter @PuroCO2Removal
