SUMMARY Increase in awareness Over the three year process all countries now experience interest in establishing measures in the industry and policy coming from a starting point of no or initial discussions. National roadmaps accepted as reference frameworks Over 1,550 stakeholders participated in the development of the national roadmaps through working groups and workshops and the main stakeholders of the future tasks have all been represented in the discussions. The process of wide stakeholder involvement and the launch of the roadmaps resulted in positive and supportive feedback. As a result, national roadmaps are accepted as reference frameworks. Alignment with EU policies National roadmaps are fully/highly aligned with EU policies (Fit for 55, Renovation Wave, Green Deal), climate– neutrality goals, Level(s) framework and Whole Life Carbon (WLC) standards. EPBD (Energy Performance of Buildings Directive) is the most important and most broadly referenced. The primary focus of the national roadmaps is on the whole life carbon approach of existing, new buildings and materials. Topics of sufficiency at building level and bio–based materials are lagging behind. Government engagement The most important stakeholders are the national and local governments, developers, manufacturers/suppliers. The highest number of endorsements and commitments occur in countries where continuous activities follow the roadmap launch. While in most countries national and local public administration were taking part in the discussions, only a few could reach policy and legislative change. As all roadmaps highlighted legal framework and incentives as key drivers to reaching the climate goals, there is still much to do in engaging governments. Transparency, data and reporting The operational data sources are EPCs (Energy Performance Certificates), mostly available for the residential sector, where the calculated data frequently differs from actual use. The embodied carbon database is scarce. GBCs focus on building EPD (Environmental Product Declaration) databases to fill in the gap. Quantitative carbon projections mostly rely on top–down models, using NATIONAL ROADMAP ANALYSIS
