Climate change is already harming the health of our patients and communities, and the health sector is on the frontline of the climate crisis. As trusted voices, health professionals are uniquely positioned to respond – and to lead. The health care sector is responsible for 8.5% of U.S. greenhouse gas emissions – and the highest per capita health care-related emissions in the world. If the sector doesn’t act, emissions are projected to triple by 2050.

There is no safe patient – or healthy community – on a sick planet. Join us to protect health, advance equity, and lead climate-smart health care.

We are ready to come together and build on one another’s successes and elevate best practices and strategies needed to empower health professionals to be leaders in this movement. 

Health Care Without Harm’s Climate-smart Collective welcomes all health professionals based in the United States or Canada. Physicians, medical students, dentists and dental students may join our dedicated Physician Network subgroup.

The collective invites members from both Practice Greenhealth partners and non-partner organizations and provides free, no-obligation, educational, media, networking, and advocacy opportunities to all members.
