Climate change has been described as the biggest threat to global health. Today, the impacts of climate change on human health are beginning to manifest across the world – from heat-related illnesses in increasingly warming Singapore, to surges in climate-sensitive mosquito-borne diseases in various parts of Southeast Asia, to air pollution due to wildfires in Australia and Canada, to worsening food and water insecurity in Africa and the Pacific islands. Healthcare systems must be ready to respond to these emerging climate-related health effects and be resilient to disasters and disruptions brought about by the changing climate. Additionally, the roots of the climate crisis – the continuous emission of carbon and other greenhouse gas emissions – must be rapidly addressed in order to slow the worsening of climate change and the emergence of its catastrophic impacts. Just like other sectors, the healthcare sector is also emitting greenhouse gases – because it uses electricity, consumes food and pharmaceuticals, produces wastes, among others. Therefore, health systems must not only adapt to climate change, but also mitigate by embracing environmental sustainability and reducing their ecological footprint. One place to begin is in primary care – the foundation of health systems, where patients and providers first interact, the vehicle for preventive health and wholistic care. This presentation will unpack the role of primary care in both sustaining health and safeguarding the planet – especially in the era of climate emergency, and will showcase emerging innovations that integrate climate resilience and environmental stewardship into primary care delivery.
