Rapidly industrializing BRICS nations face the dual challenge of development and climate change, requiring effective environmental policies to guide clean energy transitions. This study investigates the long-term, potentially non-linear relationship between renewable energy (RE) and nuclear energy (NE) consumption, economic growth, and environmental health in BRICS from 1993 to 2020. Environmental sustainability is measured using the Load Capacity Factor (LCF), which captures the balance between ecological supply and human demand. Unlike conventional approaches assuming symmetrical effects, we apply an asymmetric model to reveal more realistic dynamics. Standard models found no enduring relationship between clean energy and LCF; however, incorporating asymmetry uncovered significant long-run connections. Declines in both RE and NE consumption significantly harmed environmental health. While increases in RE had no notable effect on improving LCF, this highlights the importance of avoiding setbacks in RE deployment. In contrast, positive changes in NE consumption showed potential to enhance environmental sustainability, underlining its complementary role in the clean energy mix. Economic growth consistently exerted negative pressure on environmental sustainability, emphasizing the persistent challenge of decoupling growth from environmental degradation. These findings suggest that steady RE deployment and the integration of NE are critical for long-term sustainability in developing countries. By uncovering asymmetric effects, this study offers nuanced insights for crafting more effective environmental policies tailored to emerging economies. It emphasizes the importance of policy designs that consider the uneven impacts of energy transitions on environmental outcomes while supporting sustainable development goals.
