Our objectives


Transform the health sector to mitigate the climate crisis and its impacts on human health and accelerate the broader transition to a clean energy economy.


Ensure health systems are resilient to climate impacts and actively supporting community climate resilience as anchor institutions.


Lead the health sector in reducing social disparities intersecting with climate mitigation and resilience, and amplify the voices of the most impacted communities.

Our strategies

Lead advocacy and shape critical policy

We leverage demonstrated successes and compelling campaigns to push for public policy changes and then use these changes to accelerate tangible impact on the ground.

Expand and mobilize our powerful global network

We strengthen our network's role as advocates for climate-smart health care to build climate mitigation and resilience into their operations and throughout the communities they serve.

Transform supply chains and procurement practices

We mitigate the health care sector's adverse impact on climate, environment, and health by transforming procurement practices and supply chains and advancing a circular economy.

Deepen place-based partnerships between health care and communities

We will facilitate partnerships among community-based organizations and health systems to build replicable models for collaborative action that advances climate mitigation, resilience, and equity.
