Strategic guide helps cities build tox-free, circular, and climate-friendly futures

30 July 2025
The NonHazCity3 project has published a new guide titled “Strategic solution for managing hazardous substances in buildings and construction materials: procurement, building certificates and restrictions”, offering municipalities across the Baltic Sea Region a best practise cases and lessons learned during the project implementation.
Technical details

This document presents the strategic solutions, piloted in various municipalities, structured around a three-step management process:

  1. Needs investigation
  2. Setting vision and ambitions
  3. Market analysis and dialogue

This publication presents three tested and replicable strategic solutions:

  1. The Three-Pillar Approach – integrating tox-free, circular, and climate-friendly principles into public procurement.
  2. Use of Green Building Certificates and Eco-Labels – to ensure transparency, accountability, and sustainability throughout the building lifecycle.
  3. Supply Chain Communication and Market Dialogue – fostering collaboration between municipalities, suppliers, and stakeholders to align goals and improve outcomes.

Piloted in cities like Stockholm, Tallinn, Riga, Västerås, Helsinki, and Holbæk, the strategies have proven adaptable to different local contexts and regulatory environments. The document shares best practices, lessons learned, and practical tools such as checklists and roadmap templates to support replication.

By embedding these approaches into municipal construction planning, cities can take concrete steps toward healthier, more sustainable built environments—without waiting for national legislation to catch up.
