South African Industries and Carbon Dioxide Emissions: An Analysis of Key Sectors and Mitigation Strategies

Abstract

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 Key drivers include heavy reliance on coal, outdated infrastructure, and limited adoption of renewable energy.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.
