本論文は、オーストラリアの鉱業セクターにおける脱炭素化の進捗を、Scope 1、2、3排出量に基づいて分析。西オーストラリア州とクイーンズランド州を比較し、下流Scope 3排出が全体の90%以上を占めることを示す。再生可能エネルギーだけでは限界であり、化石燃料の段階的廃止と政策調整の必要性を強調。
English
This paper analyzes decarbonization in Australia's mining sector using Scope 1, 2, and 3 emissions. Comparing Western Australia and Queensland, it finds downstream Scope 3 emissions account for over 90% of total mining emissions. Sensitivity testing shows significant variability. The study concludes that renewable energy alone is insufficient; fossil fuel phase-out and policy alignment are crucial.

日本のGX文脈において
オーストラリアの事例は、日本の資源輸入企業がサプライチェーン排出量（Scope 3）を管理する上で重要な示唆を提供する。特に、鉱業輸出先での脱炭素化政策と整合的なScope 3報告の重要性が示されている。
In the global GX context
This paper provides empirical evidence on the dominance of Scope 3 emissions in the mining sector, highlighting challenges for global disclosure frameworks like ISSB. It underscores the need for harmonized Scope 3 reporting and policy coordination between exporting and importing countries.
👥 読者別の含意
🔬研究者:The study offers a methodology for integrating Scope 1-2-3 emissions in sectoral analysis and sensitivity testing for allocation assumptions.
🏢実務担当者:Mining companies can use the findings to prioritize Scope 3 reduction strategies and align with emerging disclosure standards.
🏛政策担当者:Regulators should consider policies that phase out fossil fuels and align national decarbonization with export practices to address downstream emissions.
📄 Abstract（原文）
Abstract Since 1990, rising energy demand and mining emissions have pushed Australia to prioritize decarbonizing its mining sector. Despite pledging to emission reduction by 2030 and net-zero by 2050, Australia’s progress in decarbonizing the energy-intensive mining sector remains limited. This paper comparatively examines the decarbonization performance of Western Australia (WA) and Queensland (Qld) which account for 86% of Australia’s mining emissions. Using a literature review and emissions modelling framework based on Scope 1 (direct), Scope 2 (purchased electricity), and Scope 3 (value chain) categories, the study analyses emissions reduction and regulatory capacity in both states. Results show that downstream Scope 3 emissions from iron-ore-to-steel processing in WA and coal combustion in Qld account for over 90% of the states’ total mining emissions. Sensitivity testing further highlights significant variability in total emissions depending on allocation factors and combustion assumptions. WA shows stronger cross-agency coordination and progress in hydrogen and critical mineral sectors while Qld has contradictory position between renewable expansion and coal dependence. From the Australian case, findings underscore that without fossil fuel phase-out, renewables have only marginal impact on mining decarbonization. To address this, effective decarbonization would require a combined approach of phasing out fossil-fuels, aligning national decarbonization policies with mining export practices, harmonising Scope 3 reporting, and reducing downstream emissions.
