Netherlands Becomes First Country to Mandate Materials Passports for All New Construction, Creating World's Largest Circular Building Database

A regulatory change implemented in January 2025 requires every building permit application in the Netherlands to include a digital materials passport — a granular record of every structural component's composition, origin, and designed disassembly pathway. The mandate is already reshaping procurement chains across Northern Europe.

The building that will be constructed in Rotterdam next spring already has a second life planned. Its structural steel has been specified with bolt connections rather than welds. Its concrete panels carry embedded RFID tags linked to mix composition data. None of this is altruism: it is compliance with the Dutch Environmental Management Act's materials passport requirement, which came into force on 1 January 2025.

The Netherlands has been building toward this regulation for six years through the Madaster platform, which has accumulated records for 340 million building components since 2017. The mandatory system extends what sophisticated developers were already doing voluntarily to the entire sector.

Early data from 4,200 buildings permitted under the new system suggests that materials passports add between 0.8 and 1.4 percent to project costs — yet buildings with detailed passports already command a four to six percent premium on commercial sales.

"We have been treating buildings as waste," said Minister for Housing Hugo de Jonge. "We are now treating them as material banks. The accounting changes everything."
