Press release - Carbon4 Finance launches a new offer about green bonds
Carbon4 Finance launches a new offer giving financial institutions access to its methodology and proprietary database covering more than 10,500 green bonds worldwide
Paris, March 10, 2026 - Carbon4 Finance, an innovative leader in methodologies and data on climate and biodiversity for the financial sector, part of the Carbone 4 group, today announced the launch of a new offer dedicated to green bonds. Through this offer, Carbon4 Finance provides financial institutions with access to its proprietary methodology and database allowing a thorough screening and assessment of the environmental impacts and merits of 10,530 green bonds worldwide.
A dual assessment framework aligned with European standards
The most innovative aspect of Carbon4 Finance methodology lies in a dual approach combining a rigorous evaluation of the project financed by the green bond with an in-depth analysis of the issuer of this green bond. Indeed, this dual-assessment framework consolidates:
- a Project assessment, appraising the positive environmental impact of the projects financed by a green bond, and relying on proprietary methodologies developed by Carbon4 Finance,
- an Issuer assessment, evaluating the green bond issuer’s transition performance, its long-term climate strategy, and its alignment with a low-carbon trajectory: the issuer evaluation is based on Carbon4 Finance’s Climate Impact Analytics (CIA) methodology.
Both assessments include dedicated ratings assigned on a 1-to-15 scale. The combination of ratings at both project and issuer level is fully aligned with the European Green Bond Standards.
For the project appraisal, data from the Climate Bond Initiative (CBI) have been selected and Carbon4 Finance has developed sector-specific methodologies to assess induced and avoided greenhouse gas emissions, as well as other regulatory data points. Among criteria considered, for each project, a Carbon Impact Ratio (CIR) is calculated to benchmark its climate impact against comparable projects. A higher CIR reflects a stronger contribution to climate mitigation.
A data-driven and scalable green bond methodology
Among the green bonds that meet the CBI's taxonomy alignment criteria (the only ones included in the analysis), Carbon4 Finance's new methodology focuses on those intended to finance projects in one of the following categories: energy, buildings, and transportation. Indeed, these three types of “use-of-proceeds” constitute the most significant sectors covered by the green bonds.
Through this new data-driven and scalable parametric methodology, Carbon4 Finance significantly expands market coverage of green bonds assessment, increases analytical granularity, allowing for more frequent updates while maintaining analytical consistency.
Virginie Wauquiez, CEO of Carbon4 Finance, stated: “In line with the methodologies and datasets we have developed to the benefits of the financial industry, assessing climate transition risks, physical risks, and biodiversity impacts and dependencies, we are very pleased to announce the launch of this new offer designed to evaluate more precisely green bonds' climate credibility and transition alignment. Integrating issuer-level analysis strengthens the reliability of green bond assessments by reducing greenwashing risks and enhancing materiality through the linkage between project-level impacts and issuer-level transition ambitions.”
Financial institutions can access Carbon4 Finance’s green bond data and assessments via its dedicated web platform or automated SFTP feeds, with no limit on the number of internal users. To ensure seamless integration, they also benefit from a direct line to Carbon4 Finance’s research team for any methodological insights.
