Advancing Chemical Safety, Climate Resilience, and Circularity in Construction Sector

The construction industry is a major contributor to na­tional gross domestic product (GDP) in the Baltic Sea Region, but at the same time it contributes to en­vironmental degradation due to hazardous chemicals, carbon emissions, and excessive waste. Many studies indicate that indoor air pollution, caused by chemicals in building materials, is a significant health. Project "Reducing hazardous substances in construction to safeguard the aquatic environment, protect human health and achieve more sustainable building" (Non­HazCity 3) integrates efforts to reduce these impacts by promoting non-toxic, climate-resilient, and circular prac­tices throughout the building lifecycle, aligning with the goals of the European Green Deal. Central to NonHazCity 3’s approach is the strategic development of criteria for “tox-free, circular, and climate-friendly build­ings” tailored to decision-making processes at public authority levels. The project particularly focuses on pro­curement as a key instrument, helping municipalities de­fine and enforce criteria for selecting safer materials and products in construction and renovation projects.
