本研究は、トルコのYES-TRとDGNBの認証制度がEUのLevel(s)枠組みとどの程度整合しているかを、定性的クロスウォークで評価した。DGNBはLCAやLCCを組み込んでおり整合性が高いが、YES-TRは全ライフサイクルGWPや循環性指標で弱い。炭素回帰時間を導入し、制度改善の道筋を示す。
English
This study assesses the alignment of Türkiye's YES-TR and DGNB certification systems with the EU Level(s) framework via a qualitative crosswalk. DGNB shows stronger alignment, while YES-TR lacks methodological equivalence for whole-life GWP, circularity, and life-cycle cost. Introduces Carbon Return Time and suggests upgrade pathways for whole-life carbon governance.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJ開示や建築物省エネ法改正が進む中、認証制度と国際枠組みの整合性は重要。本論文の比較手法は、日本版認証（CASBEE等）の国際整合性評価に応用可能で、政策立案や投資家対応に示唆を与える。
In the global GX context
As the EU moves toward mandatory whole-life carbon reporting, this paper offers a transparent method for aligning national certification systems with Level(s). It provides a model for other countries, including Japan, to benchmark their green building standards against EU policy, supporting public procurement and portfolio benchmarking.
👥 読者別の含意
🔬研究者:Provides a structured crosswalk methodology for comparing certification systems and introduces Carbon Return Time as a temporal metric for embodied vs. operational carbon trade-offs.
🏢実務担当者:Useful for building developers and certification bodies to understand gaps in national systems versus EU requirements, guiding upgrades for market access.
🏛政策担当者:Highlights how national certification can be strengthened to support whole-life carbon governance and align with EU policy, relevant for regulators designing building codes.
📄 Abstract（原文）
National green building certification systems are increasingly expected to support whole-life carbon reporting, circularity assessment and policy-facing sustainability indicators. This paper assesses the methodological alignment of Türkiye's YES-TR system and DGNB with the EU Level(s) framework, using a structured qualitative crosswalk across objectives, boundaries, life-cycle stages, metrics, quantification requirements and evidence rules. The findings show that DGNB demonstrates stronger alignment with Level(s), particularly where life-cycle assessment, life-cycle costing and quantified building-performance indicators are embedded in certification logic. YES-TR covers relevant sustainability themes, including energy, materials, water, waste and indoor environmental quality, but its current structure provides weaker methodological equivalence for mandatory whole-building life-cycle global warming potential, material quantity and lifespan data, circularity metrics, adaptability and life-cycle cost. The paper also introduces Carbon Return Time as an interpretive lens for assessing temporal carbon trade-offs between upfront embodied emissions and future operational savings. The study contributes a transparent indicator-level comparison and identifies practical upgrade pathways for strengthening national certification systems as tools for whole-life carbon governance, public procurement, portfolio benchmarking and international policy alignment.
