木材建設が森林・建築環境・化石燃料の炭素プールに与える影響を評価する、拡張性と地理的汎用性を持つ数値モデルを提示。欧州・アジア・北米の3事例で検証し、森林への影響が最大（40〜46%）で、建築環境（10〜23%）や化石燃料（9〜13%）を上回った。副産物の廃木材が一時的な炭素プールを形成し、その規模は建築環境や化石燃料の貯留量を超える場合もあった。モデルのベータ版は公開されている。
English
A scalable, geographically versatile numerical model assesses how timber construction reshapes carbon pools in forests, the built environment, and fossil fuel reserves. Across case studies in Europe, Asia, and North America, forest carbon storage was most affected (40–46%), followed by built-environment carbon (10–23%) and fossil fuel deposits (9–13%). Scrap wood formed a temporary carbon pool (22–40%) exceeding built-environment or fossil fuel storage. An open-access beta model is available.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は木造建築・CLT活用を推進しており、建築物への炭素貯留（WLC）やScope 3評価に関心が高い。本モデルは国産材利用と炭素会計の接続を検討する材料になり得るが、SSBJや有報開示への直接的な示唆は限定的。
In the global GX context
As ISSB/CSRD push whole-life carbon and Scope 3 accounting, this model offers a way to quantify biogenic carbon flows between forests and buildings. It contributes to the emerging debate on how timber construction should be reflected in corporate climate disclosure and nature-based solution accounting.

📄 Abstract（原文）
Building cities with timber has been proposed as a feasible nature-based solution to balance the global carbon cycle and mitigate climate change. The transition to timber construction offers benefits, including enhanced on-site carbon storage and reduced carbon emissions from the construction sector. This transition also imposes pressure on forests, currently playing a crucial role in offsetting global warming. At the same time, this shift reshapes carbon pools not only in forests, but also in the built environment and fossil fuel reserves. The impacts of such a transition on all the carbon pools mentioned above are poorly understood. Here, the results of a new numerical model, which is scalable and geographically versatile, are presented, and the impacts of timber construction on carbon pools are assessed for three case studies located in Europe, Asia, and North America. The case studies had the highest impact on the carbon storage in forests (40%–46% of the potential stored carbon in each case study), followed by the impact on the carbon stored in the built environment (10%–23%) and preserved in fossil fuel deposits (9%–13%). All three projects created a temporary carbon pool in the form of scrap wood, whose size (22%–40%) exceeded the amount of carbon stored in the built environment or fossil fuel deposits. The presented model should provide guidance on optimizing and comparing the benefits of timber construction projects at different spatial scales and in different regions of the world for balancing the carbon cycle. The model offers a preliminary framework for guidance, pending evaluation. An open-access beta version of the model is available online.
