日本語

本論文は、持続可能な木材を排出集約型材料の代替として気候対応型建築資材に位置づけ、オーストラリアにおける森林炭素データと会計枠組みが長期炭素貯蔵をどの程度支援するかを検討した。国際的なイニシアチブと規制メカニズムをレビューし、オーストラリアの森林資源、貿易、制度的環境を分析。国別データから、国内生産パネルに含まれる炭素は約0.63 Mt C(約2.3 Mt CO₂換算)で、収穫木材炭素の3.1~5.6%に相当すると推定。現行の会計枠組みでは森林と製品の炭素を別々に計上しており、統合的で時間分解された追跡の必要性を示唆している。

English

This paper examines how forest carbon data and accounting frameworks support long-lived carbon storage in buildings in Australia, in the context of COP28. It reviews global initiatives promoting timber construction, assesses Australia's forest resource base and institutional settings, and quantifies the carbon embodied in domestically produced wood panels as roughly 0.63 Mt C (≈2.3 Mt CO₂-eq), representing 3.1-5.6% of harvested wood carbon. The study finds that current Australian accounting frameworks treat forest and product carbon separately, highlighting the need for integrated, time-resolved tracking across the forest-wood-building chain.

日本のGX文脈において

日本でも木造建築推進と森林炭素貯留の連携が課題であり、本論文の枠組みは日本の森林・建築炭素会計の統合やSSBJ開示におけるバイオマス炭素取り扱いの参考になる。特に、日本の木材利用量の実態把握と炭素貯蔵効果の定量化手法に示唆を与える。

In the global GX context

This paper contributes to the global discourse on biogenic carbon storage in buildings, a key issue in COP28 and ISSB/CSRD alignment. It provides a national case study of Australia that illustrates the challenges of integrating forest carbon accounting with construction sector decarbonization, offering lessons for other countries developing similar policies and disclosure frameworks.

👥 読者別の含意

🔬研究者:The methodology for estimating carbon storage in wood products and the call for integrated time-resolved tracking can inform future research on biogenic carbon accounting.

🏢実務担当者:Corporate sustainability teams in timber or construction can use the findings to understand current carbon accounting gaps and advocate for better data integration.

🏛政策担当者:The paper provides evidence for designing policies that link forestry, timber supply, and building codes to maximize carbon storage, relevant for national decarbonization strategies.

📄 Abstract(原文)

Sustainably sourced timber is increasingly recognised as a climate-responsive construction material that can substitute emissions-intensive products while storing biogenic carbon in wood building products (WBPs). Following COP28, international initiatives continue to integrate forestry, carbon accounting, and construction policy into national decarbonisation pathways. In Australia, however, the extent to which forest carbon data and accounting frameworks support long-lived carbon storage in buildings remains unclear. This paper reviewed global initiatives and regulatory mechanisms promoting timber in construction, examined Australia’s forest resource base, trade balance, and institutional settings shaping domestic timber availability, and assessed how existing carbon accounting and policy frameworks capture linkages between forest carbon dynamics and wood use in buildings. Synthesised national data indicate that softwood plantations supply nearly all construction-relevant products, while hardwood plantations and native forests play minor roles under current conditions. Based on indicative national statistics for 2021–22, the carbon embodied in domestically produced panels equates to roughly 0.63 Mt C (≈ 2.3 Mt CO₂eq), corresponding to an estimated 3.1–5.6% of total harvested-wood carbon. This indicative range highlights both the measurable yet limited contribution of long-lived WBPs and the need for more detailed, end-use-specific data. Current Australian accounting frameworks quantify forest and product carbon separately, underscoring the need for integrated, time-resolved tracking. These findings clarify measurable boundaries for timber’s role in Australia’s decarbonisation goals and provide a foundation for coherent carbon accounting across the forest–wood–building chain.
