Climate change represents a pressing global health challenge, affecting human health, infrastructure, ecosystems, and socioeconomic systems worldwide. Paradoxically, the healthcare sector—tasked with mitigating climate-related health impacts—contributes significantly to greenhouse gas emissions, accounting for approximately 4.4% of global emissions according to the World Health Organization. Major sources include hospital operations, medical equipment and pharmaceutical production, transportation, waste management, research, and educational activities. In high-income countries and populous developing nations, healthcare-related emissions can constitute around 5% of national carbon outputs. These findings highlight the critical need for targeted strategies to reduce environmental impacts within healthcare, particularly in medical training programs, which play a central role in shaping sustainable healthcare practices. Implementing effective mitigation strategies in medical education can foster a generation of healthcare professionals equipped to deliver care while minimizing environmental harm.
