Amsterdam Pioneers Circular Tendering for Housing
The Amsterdam Metropolitan Area is implementing circular tendering requirements for public projects, with a recent social housing block tender serving as a model. According to podcast reports, contractors are now required to provide full lifecycle disclosure, including digital material tracking and cradle-to-cradle certification, at the procurement stage.
- The Netherlands has set a national goal to achieve a fully circular economy by 2050, with an interim target of a 50% reduction in the use of primary abiotic raw materials by 2030. The construction sector is a key focus area as it accounts for half of the country's resource use. - Amsterdam's "Circular 2020–2025 Strategy" aims to halve the use of new raw materials by 2030 and achieve full circularity by 2050. As part of this, from 2023, the city began applying circular and social criteria to all public space and building projects, including land allocation tenders. - To standardize the approach, Amsterdam developed the "Roadmap Circular Land Tendering," an instrument to help contractors secure circular building projects, which will be evaluated and potentially contribute to a national standard. By 2025, the city mandates that all new buildings must use at least 20% timber or bio-based materials. - [The Dutch government](https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQHJ9K6VSQnU-OZwGERn8M5upjygUPQTJQ8wv5aJZBg0U8-W_uXzsTiSO72gckIoONXiAoh-L5nwTjhYnGqz3-3zHizuRsUh1BEUkuXCN3Nk6WdubhGYTJNgBLVHlTTQTa6xoUWalAB6smg8O51WppRS0Qksjmmi2zAyIP0udAQEsdZxuj7DpzxfG_ISayucSOtnOYj-GigtpovnE4I=) is promoting circular procurement by implementing specific requirements such as the Circular Building Index, Building Information Modelling (BIM), and the National Environmental Database (NMD). The Platform Circular Construction 2023 (CB'23) has also developed guidelines for implementing circular design and procurement. - Material passports, which are digital documents detailing all materials within a building, are a key tool being implemented. The Dutch government is encouraging their adoption through tax incentives like the Environmental Investment Rebate Scheme (MIA) and may make them mandatory for new buildings. - The national government is actively supporting the transition through "Green Deals" for circular and bio-based construction, which aim to remove legislative and regulatory bottlenecks for sustainable initiatives. - These initiatives are framed within the broader European Green Deal, which sets ambitious targets for reducing emissions, improving energy efficiency, and promoting a circular economy across the European Union. - The Association of Netherlands Municipalities (VNG) supports municipalities in transitioning to circular models by helping to develop strategies and implement efficient waste collection, sorting, and recycling programs.
