INDICATE LIFE report explores the costs and benefits of whole life carbon assessments in Europe
A new European Union (EU) synthesis report developed within the INDICATE LIFE project and authored by Buildings Performance Institute Europe (BPIE) examines the costs and benefits of whole life carbon (WLC) assessments and low-carbon construction across Europe.
Drawing on 41 case studies from Austria, Croatia, Italy and Luxembourg, as well as evidence from European frontrunner countries, the report provides insights into the practical implementation of WLC approaches. It explores market practices, early policy experiences, and the perceived drivers and barriers to integrating life-cycle carbon considerations into building projects.
The analysis aims to address common concerns about the potential cost implications of low-carbon buildings while identifying opportunities for implementing WLC approaches in a cost-effective and practical way.
Key findings
The report highlights several important findings:
Low-carbon buildings can already be delivered at comparable or even lower cost, particularly when WLC considerations are integrated early in the design process.
The cost of conducting a building life cycle assessment (LCA) is relatively small, typically between 0.1% and 2% of total project costs, and is expected to decrease as expertise grows and processes become more routine.
A WLC perspective helps identify the most effective emission reduction opportunities, particularly through design optimisation and smarter material choices.
WLC assessments also bring wider benefits beyond emissions reductions, including improved design outcomes, skills development across the construction sector, and stronger long-term value for buildings.
Together, these findings demonstrate that adopting a life-cycle perspective can support both environmental and economic objectives in the built environment.
Supporting Europe’s shift towards life-cycle carbon assessment
The report comes at an important time for the European building sector. The revised Energy Performance of Buildings Directive (EPBD) introduces requirements to assess the life-cycle carbon emissions of buildings, marking a shift from focusing solely on operational energy performance towards considering emissions across the entire building life cycle.
Under the revised directive, the disclosure of life-cycle greenhouse gas emissions will become mandatory for large buildings from 2028 and for all buildings from 2030.
The findings from the report highlight that WLC considerations are most effective when integrated from the earliest stages of project design, rather than being introduced later in the process. Early integration allows project teams to identify cost-effective solutions, optimise material choices and avoid carbon lock-in.
National cost-benefit reports and case studies
Alongside the EU synthesis report, the INDICATE LIFE project has also published national cost-benefit reports for Austria, Croatia, Italy and Luxembourg. These reports provide a more detailed analysis of the national context in each country and include the case studies used in the research.
