NXTBLDNG supports Crelan in reporting on green bonds

Sustainable finance requires transparency, reliability and measurable insights. For Crelan, a leading Belgian financial institution, reporting on the environmental impact of its green bond portfolio was essential in 2024, both for regulatory compliance and transparent communication with investors. To support this annual green bonds impact reporting, Crelan relied on NXTBLDNG, the digital twin platform by CFP Green Buildings.

Tailored portfolio-level impact analysis

For this project, NXTBLDNG delivered a one-off data package, including a clear PDF analysis fully tailored to Crelan’s green bond portfolio. The approach included:

  • Integration of Crelan’s mortgage portfolio with external datasets, including GIM and Belmap;
  • Development of a Belgian benchmark case for comparison;
  • Calculation of carbon performance and emission reductions in carbon equivalents.

The output provided targeted insights at project level, including total energy consumption, Energy Use Intensity (EUI) and greenhouse gas emissions from both the portfolio and the reference group. Emission reductions were expressed as percentages and clearly presented in a CSV file, accompanied by a visual PDF report.

These insights were immediately usable in Crelan’s external green bond reporting to regulators and investors.

Impact: data-driven sustainability insights

Thanks to the NXTBLDNG analysis, Crelan was able to substantiate the environmental performance of its green bonds with objective figures. The bank demonstrated an average carbon reduction of 70 percent compared to a Belgian reference group, meeting international standards for transparent and data-driven impact reporting. The clarity and reliability of the analysis were highly valued, and Crelan indicated it intends to continue working with NXTBLDNG for future green bond reports.

NXTBLDNG: a solid platform for the financial sector

This impact analysis confirms the value of NXTBLDNG as a reliable data platform for the financial sector. By linking building data with external references and advanced benchmarking methods, it provides a robust foundation for sustainability assessments, investment decisions and regulatory compliance.

Through this collaboration, Crelan strengthens not only its sustainable finance strategy, but also its credibility with investors and regulators.


By adopting CFP’s NXTBLDNG platform, Crelan enhances its sustainable finance strategy. Structured and scalable building data gives the bank deeper insight into the environmental impact of its portfolio. This provides not only a strong basis for green bond reporting, but also supports responsible investment decisions and increases transparency towards stakeholders.
