About “IEA EBC Annex 89 Background information”:
This document presents the compilation of background information for the IEA EBC Annex 89 project on ways to achieve net-zero whole life carbon (WLC) buildings across diverse contexts and scales. Building on prior work and responding to the urgent need for Paris Agreement-aligned action, the compilation synthesizes current knowledge on carbon targets, assessment methods, enabling tools, and implementation strategies in the building and real estate sector.
The reports collectively address the integration of embodied and operational greenhouse gas emissions across the entire life cycle of buildings, advancing consistent, science-based approaches to decarbonisation. They explore how carbon budgets and reduction pathways can be defined and operationalised, evaluate the suitability of existing and emerging assessment frameworks, and analyse tools and instruments that support decision-making by stakeholders.
Furthermore, the compilation draws on international case studies and stakeholder engagement to identify key drivers, barriers, and conditions for the effective uptake of net-zero WLC solutions in practice. By bridging methodological development with real-world application, the background reports provide a coherent knowledge base to support policy-makers, practitioners, and researchers in accelerating the transition toward net zero WLC buildings and building stocks worldwide.
