英国の住宅ストック改修を対象に、躯体・設備・複合の3シナリオの全ライフカーボン排出を評価。南ヨークシャーでは1.5℃目標の炭素予算が3年以内に枯渇することを示し、地域のネットゼロ目標達成の困難さを定量化。住宅類型の優先順位付けの重要性を強調。
English
This study evaluates whole-life carbon emissions of UK housing retrofit scenarios (fabric, systems, combined) and shows that for South Yorkshire, any 1.5°C-compatible carbon budget will be exhausted within three years, even with grid and material decarbonization. It highlights the importance of archetype prioritization and the stark realities of regional net-zero ambitions.

In the global GX context
This paper provides a method for whole-life carbon assessment of housing retrofit, relevant to global net-zero targets and local authority climate action. It underscores the need for carbon budget alignment at regional levels, complementing national and international frameworks like TCFD and ISSB.

📄 Abstract（原文）
Abstract Global surface temperatures have already exceeded the 1.5 °C target above pre-industrial levels. With net-zero decarbonisation efforts stalling, examination and revision of 1.5~2 °C compatible 2050 carbon budgets are crucial in prioritising actions across different sectors. In addition, many local administrations have historically set more ambitious deadlines compared to their national governments for achieving net-zero. In this context, we present a whole-life carbon evaluation and prioritisation of regional housing stock retrofit delivery in the UK. Three retrofit scenarios of fabric-only, systems-only, and a combination of both are compared based on their embodied and residual operational carbon emissions. We demonstrate the increasing policy relevance for local authorities in understanding the characteristics and inequalities in carbon emissions among diverse housing archetypes, and highlight the importance of archetype prioritisation in minimising carbon budget overshoots for different decarbonization horizons. The results for regional and city-level housing stocks also demonstrate that, for the case study of South Yorkshire, any 1.5 °C compatible carbon budget will be exhausted within three years, even by integrating grid and material decarbonisation in retrofit deployment, regardless of the pace of stock decarbonisation. The extent of the carbon budget overshoot and the required retrofit delivery rates we present in this work put in sharp relief the realities of achieving regional net-zero ambitions.
