This paper explores the intersection of environmental justice and clean energy policy through a comparative analysis of case studies from the United States and Nigeria. Environmental justice, defined as the fair treatment and meaningful involvement of all people in environmental decisions, is increasingly recognized as a critical aspect of transitioning to clean energy systems. By examining clean energy policies and initiatives in both countries, this study aims to identify successes, challenges, and lessons learned in addressing environmental justice considerations. In the United States, the analysis focuses on federal and state-level clean energy policies, assessing their impact on marginalized communities and efforts to promote equity in access to clean energy resources. Similarly, in Nigeria, attention is given to government-led clean energy initiatives and their implications for environmental justice, particularly in rural and underserved areas. Through a comparative lens, this paper highlight’s common themes and divergent approaches to addressing environmental justice in clean energy policy between the two countries. It identifies opportunities for cross-country collaboration and knowledge sharing to advance equitable and sustainable energy transitions globally. The findings underscore the importance of integrating environmental justice principles into clean energy policy development and implementation, with recommendations provided for policymakers and stakeholders to promote inclusivity, fairness, and community engagement in shaping the future of clean energy.
