Make Your Pre-Verified EPD Tool Official
Do you want to create dozens or even hundreds of EPDs efficiently? A pre-verified EPD or LCA tool accelerates your EPD development dramatically – but it needs an independent tool verification first. Niels Jungbluth offers exactly this: fast, independent and standards-compliant verification of pre-verified EPD and LCA tools, for example within the International EPD System.
The Secretariat of the International EPD System (IES) has approved Niels Jungbluth as tool verifier for pre-verified Environmental Product Declaration (EPD) and Life Cycle Assessment (LCA) tools.

Why Pre-Verified Tools Need a Tool Verifier
As demand for EPD development continues to grow, more and more organisations adopt pre-verified EPD and LCA tools to enhance efficiency. Tool verifiers play a critical role in this process: they evaluate the technical robustness and methodological alignment of your tool with the relevant standards and programme rules. This work requires solid expertise in LCA methodology, software systems and database structures – exactly the expertise we bring to the table.
Dr. Niels Jungbluth, CEO of ESU-services, is approved by the Secretariat of the International EPD System (IES) and by IBU as a tool verifier for pre-verified Environmental Product Declaration (EPD) and Life Cycle Assessment (LCA) tools. He is also an approved individual EPD verifier and member of the IES Technical Advisory Body.
What Is a Pre-Verified EPD Tool?
A pre-verified tool, based on an applicable Product Category Rule (PCR), contains data and calculation models that simplify the EPD process. The International EPD System allows the use of pre-verified tools after verification. Depending on the tool type, this can:
- simplify the individual EPD verification (pre-verified LCA tool),
- generate complete EPDs including all mandatory information (pre-verified EPD tool), or
- replace individual EPD verification with an annual EPD verification (fully pre-verified and integrated EPD tool).
The result: less verification effort, faster EPD publication and lower costs per EPD – without compromising reliability or compliance.
Our Verification Services at a Glance
- Independent verification of EPD and LCA tools according to ISO 14040, ISO 14044, ISO 14025 and EN 15804
- Compliance check with the General Programme Instructions (GPI) and the relevant PCR of the International EPD System
- Documental review and validation of your tool documentation, LCA background report and pilot EPD
- Detailed, constructive feedback with a checklist prepared before you submit documentation
- Tool verification report, pilot EPD verification report and simplified EPD verification report
- Transparent fixed price, e.g. for verification of one tool with one pilot EPD
How the Tool Verification Process Works
The verification covers the underlying data, the LCA-based calculations, the presentation of environmental performance in the EPD and any additional environmental information. After project start, you receive our checklist with the main issues found in typical feedback rounds. You provide the tool documentation, the LCA background report and one pilot EPD statement. We review the documents, discuss findings in a telephone conference and guide you through usually two rounds of feedback until the documentation is ready for validation. Finally, you receive the signed verification reports for submission to EPD International.
Typical timeline: initial feedback within four weeks after receiving complete documentation, followed by revision and the final verification statement. Based on more than 140 reviews and verifications, we know exactly how to keep this phase short and efficient.
