The recent workshop on "Ethics of Climate-Smart Healthcare in Asia" held in Singapore highlights the growing importance of integrating environmental and social considerations into healthcare systems. The event brought together over 30 scholars and practitioners from different fields to discuss the challenges and opportunities of climate-smart healthcare, with a focus on equity, inclusivity, and sustainability. The workshop showcased case studies of healthcare organizations from across Asia that are implementing climate-smart healthcare strategies, such as reducing greenhouse gas emissions through composting and solar power. However, it also revealed the invisible burden of "sustaining sustainability" that falls disproportionately on nurses and women, highlighting the need for a more nuanced approach to addressing climate change in the healthcare sector. The event emphasized the importance of intersectionality and inclusivity in making climate-smart healthcare more ethical and just. The workshop's outcome is significant for ESG and sustainable development, as it demonstrates the potential for healthcare systems to play a critical role in addressing climate change while promoting human well-being. By prioritizing equity, diversity, and inclusion, the healthcare sector can unlock a sustainable future for all, particularly in Asia where climate change is already having devastating impacts on public health. The event's focus on regional collaboration and knowledge-sharing also highlights the importance of building partnerships and sharing best practices to address this critical issue.
