Over the past decade, it has become clear that the health sector is not only at risk from climate change but also a major polluter of greenhouse gases. In November 2021, the World Health Organization and partners launched the COP26 Health Programme for sustainable, climate-resilient and low-carbon health systems, and have since established the Alliance for Transformative Action on Climate and Health to support its implementation. Given the wide variation in health financing, carbon emissions and unmet health needs across the world, fair sharing of the remaining carbon budget and health gains will be critical. In this Perspective, we explore the challenges and opportunities of healthcare decarbonization, outlining the principles of fair pathways to net-zero healthcare that are attentive to health and socioeconomic inequalities within and between countries.

在过去十年中，很明显，卫生部门不仅面临气候变化的风险，而且还是温室气体的主要污染者。2021 年 11 月，世界卫生组织和合作伙伴启动了 COP26 卫生计划，以建立可持续、气候适应性和低碳卫生系统，并成立了气候与健康变革行动联盟以支持其实施。鉴于世界各地在卫生筹资、碳排放和未满足的卫生需求方面存在很大差异，公平分享剩余的碳预算和卫生收益将至关重要。从这个角度来看，我们探讨了医疗保健脱碳的挑战和机遇，
