What drove the results
With thousands of SKUs and growing customer demand for verified environmental data, RZB needed a solution built specifically for the lighting industry rather than a generic LCA tool. One Click LCA's Luminaire EPD Generator stood out for its luminaire-specific methodology, access to a comprehensive LCA database including ecoinvent data sets with regional supply chain differentiation (e.g. between European and Chinese component sourcing), and direct BOM import, which eliminated much of the manual data entry that had made EPD creation difficult to scale.
EPDs made easy: How RZB works with One Click LCA today
With the Luminaire EPD Generator from One Click LCA, RZB now produces EPDs in a streamlined and compliant way. The software supports the full input of production data, material quantities, and technical specifications—all the way through to visualizing CO₂ hotspots.
When it comes to transparent and reliable EPDs, third-party verification in accordance with ISO 14025 is crucial. One Click LCA’s Luminaire EPD Generator offers the possibility to verify your EPDs directly with an ECO Platform recognised program operator, EPD Hub. The software also supports PEP-EcoPassport, facilitating broader international applications.
Data-driven improvements: What RZB aims to achieve with EPDs
For RZB, EPDs are not just a compliance instrument but a driver of concrete environmental improvements at the product and process level such as:
- Using waste heat from waste incineration to heat production facilities
- Using recycled materials, e.g., recycled aluminum, which cuts CO₂ impact by half
- Applying circular design principles focused on repairability and longevity
The RZB example shows how deeply EPDs can shape a company’s environmental profile. At the same time, it becomes clear: without digital tools like the Luminaire EPD Generator, implementation is barely scalable. With One Click LCA, RZB not only aims to meet regulatory requirements but also to drive ecological product improvements and take customer communication to the next level.
“EPDs promote data transparency, meet regulatory requirements, and offer competitive advantages,” summarizes Péter Gyenge. “Our software helps overcome those hurdles.” For architects, planners, procurement and sustainability professionals, now is the time to engage with EPDs — not just as a compliance requirement, but as a tool for differentiation.
