Climate change, environmental conditions, and natural hazards hugely impact human health and well-being. In turn, health services and healthcare systems can influence the climate and environment. The One Health approach to the health-climate-hazard-environment relationships can uncover co-benefits to be found in development activities.

This thematic integration brief provides a non-exhaustive compilation of the relationships between human health and health systems, and climate change, disaster risk (from natural hazards), and the environment (C/D/E).

The brief:

• helps explain potential risks for health and healthcare systems

• highlights possible adverse impacts of health systems on climate and environment

• offers practical advice on how to integrate C/D/E in health sector, and on how to add value, assure greening, and risk-proof the sector.
