[Natural Capital Data x Finance] International Framework PBAF, Joined by 74 Financial Institutions, Implements Scientific Models (GLOBIO, ReCiPe) as Foundation into Natural Capital Data API "Carbontribe Engine"

Carbontribe Labs (Headquarters: Estonia, CEO: Keiichiro Yano), developer of the natural capital data API, announced that it has implemented the scientific models (GLOBIO, ReCiPe) referenced by PBAF (Partnership for Biodiversity Accounting Financials), an international partnership of financial institutions working on standardizing biodiversity accounting, into its natural capital data infrastructure "Carbontribe Engine." As of June 2025, PBAF includes over 74 financial institutions from 22 countries with over $16 trillion in assets under management.

This enables companies adopting Carbontribe Engine to present their investment activities and progress in biodiversity and water resources as traceable and verifiable data assets to financial institutions using existing international frameworks.

This mechanism connects corporate environmental initiatives to fundraising capabilities and cost of capital, paving the way for the next stage of asset securitization of environmental value, following the commoditization of carbon credits.

About PBAF: PBAF (Partnership for Biodiversity Accounting Financials) is an international partnership of financial institutions originating in the Netherlands, working to standardize the assessment and disclosure of the impact of investment and lending on biodiversity. It involves 74 financial institutions with over $16 trillion in assets under management, and its assessment methodologies are based on scientific models such as GLOBIO and ReCiPe.

Background: Maturation of Carbon and Transition to "Natural Capital x Finance" The carbon credit market is maturing, and its value is becoming commoditized. Meanwhile, "natural capital," such as biodiversity and water resources, is rapidly gaining attention as the next frontier for environmental value.

The global financial sector has already begun moving into this area. PBAF, an international framework for biodiversity accounting, was launched in 2019 as a sister initiative to PCAF (Partnership for Carbon Accounting Financials), the international framework for financial institutions' carbon accounting. It represents a move to extend the discipline of "measure, disclose, and set targets," which has been standardized in carbon, to biodiversity.

Financial institutions with over $16 trillion in assets under management participate in PBAF, and their numbers continue to grow monthly. These assessment methodologies are based on scientific models such as GLOBIO and ReCiPe.

However, infrastructure to connect these scientific assessments with actual corporate activities and establish them as "data" that investors can track and verify has not existed until now. Carbontribe Engine is being developed to fill this gap.

Features of Carbontribe Engine

Implements Scientific Models Referenced by International Financial Institutions: Developed by incorporating models such as GLOBIO and ReCiPe, referenced by frameworks like PBAF, for the assessment of biodiversity and water resources.

Automation via AI x Blockchain: Automates everything from the generation of environmental impact data to its recording, issuing it as digital data assets (RWAs) based on the ERC1155 standard.

Verification by Third-Party Certification: Ensures data reliability, traceability, and verifiability through methodologies certified by the international third-party certification body Earthood.

Data Design Connected to Finance: Enables companies to present their natural capital initiatives as institutional investor-grade data that financial institutions can track and verify.

Significance for Companies:

Previously, corporate responses to biodiversity and water resources were often viewed as compliance costs. Carbontribe Engine reverses this premise.

By presenting activities investing in natural capital as verifiable data to financial institutions, companies can strategically leverage their environmental initiatives as drivers for fundraising and reducing the cost of capital. Environmental response shifts from a "defensive cost" to an "offensive driver" that enhances corporate financial competitiveness.

Comments from Representatives:

"To enable finance to handle biodiversity and water resources, a foundation of internationally validated science is necessary for assessment. That is why we implemented GLOBIO and ReCiPe—the scientific models referenced by financial institutions for biodiversity assessment—into our engine. I myself am connected to the European natural science network centered around Wageningen University and build upon that knowledge. The truly difficult part is not the model itself, but connecting it with corporate actual data and making it a 'data asset' that third parties can verify and that can withstand investment decisions. Carbontribe Engine provides that transformation as an API." — Julia Sluis, Science Lead, Carbontribe Labs

"Carbon credits were an important first step, but they are already becoming commoditized, and differentiation of environmental value is moving to the next stage. What we are looking at is transforming natural capital such as biodiversity and water resources into 'data assets' that companies can prove to financial institutions. Environmental initiatives are no longer a cost, but the very financial strategy that influences a company's fundraising ability and cost of capital. Carbontribe Engine aims to be the infrastructure that supports this change." — Yuki Kato, Co-founder and CTO, Carbontribe Labs

Carbontribe Labs is a data infrastructure company that transforms natural capital data into institutional investor-grade data assets. Through its Carbontribe Engine, the company aims to create an environment where both companies and financial institutions can utilize natural capital data as a common language. Moving forward, the company plans to build an ecosystem that connects natural capital data to investment decisions and capital allocation, with an eye toward collaboration with domestic and international financial institutions.

Environmental investment data from companies is automatically ingested via API connection from various infrastructures, and environmental value is automatically calculated through AI and third-party certification. Environmental data is converted into "digital assets usable for investment decisions" and stored on the blockchain.

Data managed by corporate infrastructure is connected via API and converted into third-party certified environmental value data, compliant with frameworks referenced by international financial institutions.

Carbontribe's AI and Web3-based methodology has been certified by the international third-party certification body Earthood.
