1. ***Could you please introduce yourself?***
*Name, role, company, location, and NGI Sargasso-funded project.*
Christoph Fabianek and Martin Kjäer from OwnYourData.
Julia Flaszynska and Thomas Romm from ZT Romm.
We are based at / near Vienna in Austria and received funding in the NGI Sargasso 2nd Call with the project "DPP-CRC" Digital Product Passport for Carbon-Reduced Concrete.
   
2. ***Could you briefly describe DPP-CRC?***
*Solutions you are offering, challenges faced, and how you overcame them, etc.*
The project utilises SSI technologies and Zero-Knowledge Proofs to create process conform Digital Product Passports in line with the EU Green Deal. It targets Europe’s growing carbon-reduced concrete market with the goal to collect and present verified, tamper-proof data along the production chain. This is vital in construction for reducing concrete’s carbon footprint.

3. ***Can we talk about the results of the project?***
*Tell us a few main things you are proud of!*
We successfully developed and validated a digital framework for Environmental Product Declarations (EPDs) using Self-Sovereign Identity (SSI) technologies and Zero-Knowledge Proofs (ZKPs) to enhance transparency and data integrity while preserving privacy. It was possible to demonstrate real-world applicability in European and Canadian markets, aligning with the EU Green Deal and Data Governance Act (DGA) to support sustainable construction. The project also facilitated partnerships with local businesses, and we used a data intermediation service provider for secure data sharing.

4. ***What tangible impact has your project created so far?***
*e.g., technological, social, economic, environmental*
Our project has made a tangible impact across scientific, economic, and industrial domains. Scientifically, Christoph Fabianek co-authored Handbuch Datenschutzrecht (Data Protection Law Handbook), and the team secured the PACE-DPP research project, advancing knowledge in data protection and privacy. Economically, partnerships with local businesses and the launch of intermediary.at have facilitated practical applications and expect long-term economic benefits.

5. ***How did DPP-CRC evolve during the NGI Sargasso program months?***
*What was the status of your project before and after the program?*
Initially we focused on Environmental Product Declarations (EPDs) for concrete, but the project evolved into a broader Digital Product Passport (DPP) framework covering the entire building lifecycle. Through extensive stakeholder interviews, the team gained valuable insights into industry needs, leading to refinements in data sharing, validation methods, and regulatory alignment. A key lesson learned was the strong dependency on upcoming EU regulations to drive industry adoption. The project successfully integrated Zero-Knowledge Proofs (ZKPs) and Self-Sovereign Identity (SSI) technologies to ensure secure, privacy-preserving data exchange across the construction supply chain.
The main difference before and after the project was the transition from theoretical research to practical implementation, establishing a Data Intermediation Service Provider to facilitate trusted data transactions. With this foundation, we are now positioned for scalability and continuing our work within the PACE-DPP research project.

6. ***How did the NGI Sargasso program support you?***
*What aspect of the program was the most useful to your project?*
The NGI Sargasso program provided us coaching, networking opportunities with stakeholders through extensive interviews, and funding, enabling us to refine our Digital Product Passport (DPP) framework and expand the scope beyond concrete to entire buildings.

7. ***How did collaboration with your USA/Canadian partner contribute to the development of the project?***
The collaboration with our Canadian partner was important in the initial validation of the project idea, providing critical feedback on the feasibility and applicability of Digital Product Passports (DPPs) in construction. Additionally, they supported the project by facilitating interviews with key industry stakeholders, helping to refine the use cases and adapt the solution to real-world market needs in both Europe and North America.

8. ***What’s next for DPP-CRC? Do you plan to take the idea further after the NGI Sargasso funding ends?***
The DPP-CRC project will continue its development through the national PACE-DPP project, further advancing Digital Product Passports (DPPs) with a focus in the forestry sector. We applied for NGI TRUSTCHAIN funding to extend our scope into Data Altruism, enabling more transparent and ethical data-sharing models. Additionally, we will continue refining and expanding use cases for our Data Intermediary, ensuring compliance with EU regulations and fostering industry adoption.
