This academic publication dives into the complexities of decarbonising Europe's existing buildings. It emphasises that there's no universal solution due to the diversity of building types and climates across the continent. The report discusses the importance of selecting the right renovation depth and sustainable technologies to make buildings greener. It also highlights the added benefits like improved health and comfort for occupants, better energy security, and increased property value.

Moreover, the document stresses the need to reuse and recycle building materials to reduce both embodied and operational emissions. Key players in this green transition include policymakers, investors, banks, the construction industry, and researchers.
