この論文は南アフリカの主要産業（エネルギー、鉱業、製造業、運輸）によるCO2排出を分析し、石炭依存の現状と緩和戦略（再生可能エネルギー、効率改善、炭素回収、グリーン水素など）を検討する。特にエネルギー部門が排出の約80%を占め、政策の民主化も重要と指摘する。南アフリカ固有の実証分析であり、新興国における排出削減の事例として参考になる。
English
This paper analyzes CO2 emissions from key South African sectors (energy, mining, manufacturing, transport), highlighting coal dependence and mitigation strategies such as renewables, efficiency, CCS, and green hydrogen. The energy sector contributes ~80% of emissions. It emphasizes policy democratization for balancing growth and reduction. While context-specific, it offers insights for emerging economies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
南アフリカの石炭依存型経済の分析は、日本のエネルギー政策と直接的な関連は薄いが、新興国における排出削減の課題を理解する上で参考になる。特に、政策決定におけるコミュニティ参加の重要性は、日本の地域エネルギー転換にも示唆を与える。
In the global GX context
This paper provides a case study of a coal-dependent emerging economy, contrasting with Japan's post-Fukushima energy mix. It highlights challenges in balancing economic growth with decarbonization, relevant for global discussions on just transition.

📄 Abstract（原文）
South Africa, a leading economic hub in Africa, significantly contributes to carbon dioxide (CO₂) emissions due to its reliance on carbon-intensive industries. This reliance contributes to emissions across major sectors, including the energy generation sector, the mining sector, which is characterized by significant Scope 2 electricity consumption and Scope 3 value chain emissions, the manufacturing sector, and the transportation sector. This study examines the primary sectors mentioned as the driving force to emissions. The analysis is based on trends, key drivers, and potential mitigation strategies grounded by recent studies and government reports. The broader energy sector is the dominant contributor, accounting for approximately 80% of South Africa’s CO₂ total emissions, primarily due to coal-based power generation. Manufacturing, including steel and cement production, contributes significantly due to high energy consumption and process-related emissions. The transportation sector, driven by fossil fuel-dependent road and freight systems, adds to the emissions profile, though to a lesser extent. Emission trends show a steady increase over the past decade, with South Africa’s per capita emissions among the highest in Africa. Key drivers include heavy reliance on coal, outdated infrastructure, and limited adoption of renewable energy. Mitigation strategies include transitioning to renewables like solar, wind and hydro power improving energy efficiency, and adopting carbon capture technologies. Policy democratisation is important through engaging communities and engaging industries in decision making to balance economic growth and emissions reduction. Technological interventions, such as green hydrogen and electrified transport, offer further potential. Implementing these measures is critical for sustainable development in South Africa.
