本論文は、ネットゼロ2050を目指す豪州の石油・ガス部門を対象に、NGER報告から強化セーフガードメカニズム、強制気候関連財務開示、州の環境承認制度へと至るGHG規制の進化を整理する。州間のGHG評価手法を比較し、排出量算定や回避・削減・代替・オフセットの階層、ネットゼロ整合への収斂と規制裁量の差異を示す。特にクイーンズランド土地裁判所の判決がScope 3責任やカーボンバジェット整合性の基準を引き上げた点を重視し、GHG枠組みが移行リスク定量化の証拠基盤となると論じる。脱炭素手法の実務的評価も提示する。

English

This paper maps Australia's evolving Commonwealth and state GHG framework for the oil and gas sector, from NGER reporting to the strengthened Safeguard Mechanism, mandatory climate-related financial disclosures, and environmental approvals. Comparing six jurisdictions, it finds convergence on emissions quantification and net-zero alignment but wide variation in prescriptiveness and regulator discretion. Queensland Land Court rulings (Waratah Coal v Youth Verdict) raise the bar for Scope 3 accountability and carbon budget consistency. It argues GHG reporting increasingly underpins transition-risk quantification and reviews decarbonization options for operators.

日本のGX文脈において

豪州の強制気候関連財務開示とセーフガードの連動は、日本企業がSSBJ基準や有報での気候開示、Scope 3対応を進める上で先行事例となる。特にプロジェクト承認と企業開示の収斂は、海外資産を持つ日本企業の移行リスク管理に示唆を与える。

In the global GX context

Australia's coupling of mandatory climate-related financial disclosure with the Safeguard Mechanism offers a live test case for how project-level approvals and company-level disclosure converge — directly relevant to ISSB adoption debates and CSRD-aligned transition planning globally. The Scope 3 and carbon-budget reasoning in Waratah Coal v Youth Verdict signals how litigation may shape disclosure expectations beyond Australia.

👥 読者別の含意

🔬研究者:規制収斂と裁量差、Scope 3司法判断が開示研究に与える含意を整理する材料となる。

🏢実務担当者:豪州事業を持つ企業は、承認リスクと開示義務を統合した移行計画の設計に活用できる。

🏛政策担当者:プロジェクト承認と企業開示を連動させる制度設計の先行例として参照価値が高い。

📄 Abstract（原文）

Australia's oil and gas (O&G) sector is navigating an increasingly complex climate policy landscape as the country pursues net-zero emissions by 2050. This paper examines the Commonwealth and state GHG legislative, regulatory, and policy framework affecting the sector, tracing its evolution from emissions reporting (under NGER) toward demonstrating emissions performance and credible decarbonization pathways through the strengthened Safeguard Mechanism, mandatory climate-related financial disclosures, and Federal and state environmental approval regimes. It compares GHG assessment approaches across Queensland, NSW, Victoria, Western Australia, South Australia, and the Northern Territory, highlighting convergence around emissions quantification, an avoid–reduce–substitute–offset hierarchy, and net-zero alignment, alongside significant variation in prescriptiveness and regulator discretion. Particular attention is given to recent Queensland Land Court rulings (notably Waratah Coal v Youth Verdict), which have raised the bar for Scope 3 accountability, carbon budget consistency, and human rights considerations, with implications extending nationally. The paper situates this regulatory architecture within the climate-related financial risk disclosure (CRFD) process, arguing that Australia's GHG framework increasingly provides the evidentiary basis for quantifying transition risk. It also presents a practical summary of decarbonization methods available to O&G operators — electrification, methane management, carbon capture and storage, low-carbon fuels, and digital optimization — assessed against benefits, challenges, and approval risk. The paper concludes that transition risk is increasingly less about the survival of demand and more about sustaining competitiveness and demonstrating a credible, financially resilient emissions reduction trajectory. O&G proponents face materially similar convergence between project-level approvals and company-level disclosure internationally, and Australia's example provides a robust test for proponents weighing final investment decisions.
