Case Study: Licht & Donker Advies drives circular public lighting with Ecochain software

Licht & Donker Advies lowers luminaire ECI with Ecochain, with 4 suppliers and 7 municipalities

Licht & Donker Advies, a Dutch lighting consultancy firm, faced the challenge of making circularity measurable for the public lighting sector. With many Dutch municipalities beginning to request quantitative environmental data like the Environmental Cost Indicator (ECI) in tenders, they needed a way to help both suppliers and governments understand and apply Life Cycle Assessment (LCA) methodologies. They sought help from vendor Ecochain and its product LCA solution, Mobius, to initiate a frontrunner project.

Ecochain implemented a solution by creating a tailored manual for the ECI and facilitating a project with four luminaire suppliers and seven municipalities. They performed LCAs to analyze the environmental impact of luminaires, which helped suppliers identify key areas for improvement, such as material choice. The project resulted in all four suppliers achieving a lower ECI score than expected, established new benchmarks for the sector, and provided governments with clear reference values for sustainable procurement. Ecochain's software provided a dedicated database of materials, significantly increasing the ease with which suppliers can perform their own ECI calculations.
