This report stresses the urgent need to address greenhouse gas emissions in construction through research and pilot projects. The key recommendations focus on planning, design, environmental impact assessment, energy, waste reduction, regulations and financial incentives. Emphasizing Life Cycle Assessment (LCA) integration in Nordic regulations for estimating emissions, highlights the necessity of harmonizing methods for low-carbon solutions. Addressing data gaps in transport-related emissions and waste, it proposes enhancing collection methods, and exploring energy efficiency, battery electrification, and hydrogen technologies despite infrastructure limitations and cost barriers. Overall, it advocates for gathering emissions data, fostering stakeholder cooperation, and aligning regulations to create a more sustainable construction industry.
