This COP28 Prospectus of Climate & Health Solutions presents case studies on a range of high-impact, evidence-backed interventions that can be rapidly scaled up to address climate change while simultaneously achieving health gains. The case studies featured here demonstrate solutions that have been implemented in countries at different levels of health sector performance, resourcing and maturity. The examples included here are neither comprehensive nor exclusive; instead, they aim to illustrate the diversity and scope of climate and health solutions already being implemented.
