The new European directive EPBD requires measuring the climate impact of buildings from construction to demolition. This guide explains how to calculate it, when to report it, and what steps to take for the built environment to truly support climate neutrality.
The latest revision of the Energy Performance of Buildings Directive (EPBD) introduces, for the first time, a requirement to calculate and disclose the Global Warming Potential (GWP) of buildings across their entire life cycle. Coming into force progressively between 2028 and 2030, this marks a structural shift in how the sustainability of Europe’s building stock is assessed.
The document produced by the World Green Building Council (WGBC) provides Member States with a clear roadmap, including concrete steps, key dates, and enabling conditions to implement this new requirement. Integrating GWP into Energy Performance Certificates (EPCs) and mandating national roadmaps with differentiated targets by building type and climate zone signals a move towards truly decarbonised buildings.
Beyond regulatory compliance, the focus on GWP sheds light on hidden emissions from materials and construction processes—especially relevant as operational emissions continue to fall. The report highlights the need for national databases, harmonised methodologies, and trained professionals to carry out robust assessments. It also proposes exemplary measures such as advancing requirements for public buildings and launching pilot projects.
