国際PGM協会が2022年データに基づく第3次LCAを発表。石炭火力依存の南アフリカの電力構成がPGM鉱山のGWPを押し上げる要因であることを指摘し、再生可能エネルギー導入シナリオにより2030年までにグローバル鉱山のGWPを35〜61%削減可能と試算。
English
The IPA published its third LCA of global PGM production based on 2022 data, showing that South Africa's coal-intensive grid is the main driver of mining emissions. Scenario analysis indicates a 35-61% reduction in global warming potential by 2030 through shifting to renewable electricity.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は自動車触媒等でPGMを大量輸入しており、サプライチェーンScope3排出量の削減が課題。南アフリカの電力脱炭素化の進捗は日本の間接排出量に直結するため、本分析は日本企業の調達戦略において重要な指標となる。
In the global GX context
This study underscores that grid decarbonization is the most effective lever for reducing mining emissions, directly supporting ISSB-aligned Scope 2 accounting and transition planning. For global PGM buyers, the 35-61% reduction potential provides a benchmark for supply chain decarbonization targets.

📄 Abstract（原文）
In 2025, the International Platinum Group Metals Association (IPA) published its third industry-wide life cycle assessment (LCA) of global primary and secondary platinum group metal (PGM) production, based on 2022 data. The critical reviewed study showed an increase in the global warming potential (GWP) of PGM mining compared with the previous study on 2017 production, mainly due to temporary external factors, particularly high carbon dioxide emissions from South Africa’s coal-based electricity grid. For example, in platinum production, power consumption during mining, beneficiation and smelting together accounts for approximately 57% of total carbon dioxide emissions (43% in the case of palladium, as palladium is also mined in high quantities outside South Africa). Thus, shifting fossil electricity use toward renewables offers the greatest potential for decarbonising PGM mining and forms a sound basis for a carbon dioxide scenario analysis. Given South Africa’s dominant contribution to the production volumes reported in the 2022 study, IPA focused its scenario analysis on the decarbonisation potential of South African primary production by 2030. The scenario modelling was based on investment plans by South Africa’s electricity provider, Eskom, to increase the share of renewable energy in the national grid by 2030 as well as planned investments by mining companies. Our results indicate that reductions between 35% and 61% in the GWP of global PGM mining are achievable.
