Résumé
Limiting global warming in line with the Paris Agreement requires rapid and ambitious decarbonisation of the global building and real estate (BRE) sector. This study presents the first global systematic review and structured alignment assessment of BRE decarbonisation efforts from 212 publications over the past two decades, evaluating them against six relevant alignment factors: temperature-based targets, main indicators, life-cycle scope, decarbonisation goals, target years and assessment scales. Using a multi-criteria scoring and weighting framework, the analysis reveals the evolution and prevalent shortcomings in research. Only four studies are Paris-aligned, while most efforts remain fragmented, narrowly scoped, low in ambition, or disconnected from explicit temperature limits and mid-century net zero goals. Although ambition has increased since 2015, inconsistent terminology, incomplete life-cycle scopes, small assessment scales and delayed policy uptake persist. Significant geographical disparities are evident, with Europe and Oceania leading in whole-life-cycle approaches, while Africa, South America and much of Asia remain underrepresented, despite rapid projected growth in building stocks. The findings demonstrate that current BRE decarbonisation trajectories are largely incompatible with Paris-aligned pathways. Three priority research areas are identified: harmonised definitions and ambition levels, robust data infrastructures, and scalable sector-wide frameworks to enable Paris-compatible decarbonisation within planetary boundaries.
