本論文は、鉱業・金属業界の脱炭素化の現状を、20社の大手企業の公開情報に基づき分析。短期的には再生可能エネルギー導入が効果的だが、長期的にはカーボンオフセットや水素などの革新的技術が必要と指摘。ネットゼロの定義、長期戦略の実現可能性、Scope3目標設定におけるLCAの役割の3点が未解決であると論じる。
English
This paper analyzes the decarbonization progress of the mining and metals industry based on public documents from 20 major companies. It finds that while renewable energy deployment drives short-term emission reductions, long-term targets rely on offsets and breakthrough technologies like green hydrogen. Three open questions remain: the practical meaning of Net Zero, credibility of long-term strategies, and the role of Life Cycle Assessment in Scope 3 targets.

日本のGX文脈において
日本の鉱業・金属業界（例：JX金属、三菱マテリアル）はSSBJ対応や有報での気候関連開示が進む中、本論文のScope3目標設定やLCA活用の議論は実務上有用。特にカーボンオフセットの位置づけは日本のGX政策でも重要。
In the global GX context
This paper contributes to global GX discourse by critically examining Net Zero strategies in a hard-to-abate sector. It highlights the gap between short-term renewable deployment and long-term reliance on offsets and unproven technologies, relevant for ISSB and transition finance frameworks.

📄 Abstract（原文）
Abstract The mining and metals industries are facing the conflicting challenges of meeting an anticipated skyrocketing metals demand while drastically decarbonizing and reducing other environmental impacts. Over the past few years, decarbonization has become a key topic within the sector, with global scale initiatives and a massive response from companies. Here, we provide a snapshot of the industry’s progress towards decarbonization, building on the most recent research papers, industry reports, and the public corporate documents of twenty major mining and metals companies. The objective is to highlight how the concept of Net Zero (NZ) has been interpreted within the sector and critically discuss the key strategies to achieve it. Today, nearly all the leading companies have set ambitious decarbonization targets, with many aiming to achieve Net Zero operational emissions (Scope 1 and 2) by 2050. According to the proposed decarbonization roadmaps, massive deployment of renewable energy is likely to drive substantial emission reductions in the short-term (before 2030). Instead, long-term decarbonization targets (2050) are expected to be achieved by combining carbon offsets strategies with the implementation of multiple breakthrough technologies, such as battery electric mining trucks, process heat electrification, and green hydrogen. Despite the ambitious goals, sometimes underpinned by clear roadmaps and remarkable investment agendas, three questions remain open and the responses uncertain to various extent: 1. What does NZ mean in practice for the sector? 2. To what extent long term strategies that companies announced are viable and credible? 3. What’s the role of Life Cycle Assessment in setting and monitoring Scope 3 reduction targets?
