摘要

In light of the unsustainable energy consumption and significant greenhouse gas emissions threatening South Africa’s gold mining sector, this study examined how environmental sustainability principles and climate change adaptation measures are integrated to enhance resilience and energy efficiency. Guided by three research questions; identifying climate change impacts on energy use, assessing sustainability practices implemented by mining companies, and exploring how a conceptual framework can guide integration; the study employed a mixed-methods case study approach using purposive and snowball sampling of 30 participants across ten Witwatersrand Basin operations, complemented by documentary reviews, site observations, and quantitative climate and energy data. Findings revealed that mean annual temperatures in the Free State Province are projected to rise by +2.3 °C, with very hot days (>35 °C) nearly doubling, intensifying thermal stress and driving cooling demand; yet, electricity consumption declined from 1231 GWh in 2020 to 1071 GWh in 2023 due to targeted efficiency programmes. Interviews confirmed strong awareness among sustainability officers and mining experts, with 100% reporting adoption of energy-saving initiatives such as optimized refrigeration, advanced ventilation systems, and seasonal cooling controls, while 77–83% emphasized energy efficiency as both a sustainability principle and adaptation strategy. Overall, the study demonstrates that climate change is reshaping energy consumption patterns, but proactive integration of energy efficiency and renewable energy projects can simultaneously reduce costs, lower emissions, and strengthen resilience. These findings imply that embedding sustainability into adaptation frameworks is essential for ensuring the long-term viability of gold mining operations and aligning industry practices with national and global sustainability goals.
