Clinicians for Planetary Health (C4PH)

Physicians, nurses, and other health professionals are at the frontlines of protecting our health – therefore, they have a unique capacity to understand and communicate the shifting landscape of planetary health challenges and the strategies that individuals can take to safeguard their health and the health of the environment. The Clinicians for Planetary Health initiative is a global effort to galvanize health professionals, patients, and communities around planetary health through lifestyle modifications and activism.

Who we are:
- Clinicians are people providing healthcare for individuals and communities. This includes physicians, physician assistants, nurses, nurse practitioners, midwives, dietitians, traditional healers, community health workers, and others.
- Over 700 clinicians from around the world have formally signed on to the Clinicians for Planetary Health initiative, expressing their commitment to addressing global environmental change and its health impacts. A subset of these individuals are involved in the Clinicians for Planetary Health working group.
- Over 30 partner organizations co-signed the global call-to-action released in The Lancet on Earth Day 2019, which called on health communities around the world to take action on planetary health.

Our approach:
- Developing outreach materials for healthcare settings that encourage individual- and community-level planetary health action, with an emphasis on health and environmental co-benefits
- Convening periodic calls to brainstorm, network, and exchange resources to build commitment to planetary health across the healthcare sector
- Sharing resources and stories of success through a newsletter, blog series, and podcast
