Understanding the flow of materials through the Dutch construction sector is crucial for transitioning towards a more sustainable and circular economy. Building on previous studies for 2014 and 2019, a comprehensive material flow analysis provides updated insights for the base year 2023 and looks ahead to 2030 and 2050.

This analysis employs a detailed, bottom-up methodology, utilizing specific building profiles linked to construction, renovation, and demolition forecasts. It quantifies the inflow and outflow of materials within the residential and non-residential building sector, tracks their origin (primary, secondary, or renewable), and assesses key environmental impacts, specifically the Environmental Cost Indicator (MKI) and material-related CO₂​ emissions.

To explore future pathways, the study evaluates three distinct scenarios: a 'business-as-usual' baseline, an 'autonomous' scenario incorporating existing policies and trends, and a third scenario reflecting potential additional policy measures. This forward-looking analysis helps anticipate the effects of different developments on resource use and environmental performance.

The results offer valuable, focused insights for both policymakers and industry stakeholders. By clearly identifying the scale of material use, major contributing product groups, and associated environmental pressures, the analysis provides a robust foundation for prioritizing actions and accelerating the transition towards the Netherlands' circularity and climate goals.
