This chapter explores the intersection of just transition and health within the Belgian healthcare landscape, emphasizing a holistic approach that integrates social, economic, commercial, and environmental dimensions of health determinants. As societies strive for sustainable development, ensuring that transitions to greener economies do not exacerbate or create new health and socio-economic inequities is critical. We define just transition and its relevance to health, highlighting fairness, inclusivity, and participation as key principles. A just transition can improve health outcomes by reducing environmental hazards, enhancing air and water quality, and fostering climate-resilient health systems. However, the climate transition process presents risks and challenges for health and well-being, especially for vulnerable populations. Addressing these disparities through equity-focused approaches is vital for enhancing health equity and social justice. Community engagement, participation, and capacity-building play essential roles in promoting well-being during this transition. Collaborative decision-making processes involving diverse stakeholders—such as affected communities, health professionals, policymakers, and industry representatives—are emphasized. Additionally, the chapter examines the potential for innovative partnerships and policy interventions to ensure a smoother, more equitable transition while safeguarding public health. This chapter aims to explore an integrated approach that aligns economic, social, and environmental objectives with public health goals, to ensure sustainable development and foster a healthier, more inclusive, and prosperous future for all.
