日本語
本レビューは、世界の主要な低炭素建築基準・規格を比較分析し、規制手法（規範的・性能ベース）、実施能力、炭素・ライフサイクル指標の採用状況の違いを明らかにする。強化された建築基準は、特に遵守体制が整っている場合に運用エネルギーと排出削減に効果的であるが、自主基準は性能は高いものの市場カバレッジに限界がある。電力の脱炭素化に伴い、体化炭素とライフサイクル排出の重要性が増す一方、既存の枠組みは運用エネルギーに偏重している。政策提言として、ライフサイクル志向の指標、執行強化、国際的な知識共有を挙げる。
English
This review compares global low-carbon building codes and standards, highlighting differences in regulatory approaches (prescriptive vs. performance-based), implementation capacity, and adoption of carbon and life-cycle metrics. Reinforced codes effectively reduce operational energy and emissions, especially with robust compliance, while voluntary standards perform better but have limited market coverage. As electricity decarbonizes, embodied carbon and life-cycle emissions become significant, yet existing frameworks focus on operational energy. The review suggests life-cycle-oriented metrics, enhanced enforcement, and international knowledge exchange.

日本のGX文脈において
日本では、2025年4月から建築物省エネ法の適合義務が拡大され、住宅・建築物の省エネ基準適合が義務化される。本レビューの国際比較は、日本の規制の位置づけを相対化し、ライフサイクル炭素評価や体化炭素の扱いなど、今後の制度設計に示唆を与える。特に、運用エネルギー偏重の現状を踏まえ、体化炭素を含む評価への移行が日本のGX実践に重要である。
In the global GX context
Globally, building codes are a key policy lever for decarbonization, with the EU's Energy Performance of Buildings Directive and the US's evolving codes. This review provides a comparative framework that can inform ISSB-aligned disclosure and transition finance by highlighting the need for life-cycle carbon metrics. It underscores the gap between operational and embodied carbon, which is critical for investors and policymakers assessing building-sector transition risks.

📄 Abstract（原文）
The construction industry contributes a considerable portion of the world's energy demand and emissions of greenhouse gases; therefore, it is an important area where efforts should be directed in reducing the climate change. Building codes and standards. Low-carbon building codes and standards have become major controlling tools with the aim of enhancing building performance and minimizing environmental impacts. This review offers a comparative analysis of key low-carbon building codes and standards across the world, how they are designed, how they are implemented, and what environmental impacts they report. Both the mandatory building codes and voluntary standards are taken into consideration in both mature and developing areas with varied climates, economic, and institutional backgrounds. The analysis draws out the significant difference in regulatory strategies, such as prescriptive and performance-based models, disparities in implementation capacity, and uneven adoption of carbon-based and life-cycle performance indicators. Literature evidence suggests that reinforced building codes have provided substantial operational energy consumption and emissions containment, especially where a robust compliance system is in place. Voluntary standards tend to show a better level of performance, but are restricted by the market coverage. With the decarbonization of electricity systems, the proportion of embodied carbon and life-cycle emissions becomes significant, and the drawbacks of the existing regulatory frameworks, which continue to emphasize mainly operational energy efficiency, can be seen. The review provides such methodological issues in the evaluation of environmental effectiveness as the use of ex-ante modeling and a lack of post-occupancy data. It concludes with policy implications and further suggestions for improving the low-carbon building regulation through life-cycle-oriented metrics, enhanced enforcement, and the exchange of international knowledge.
