The food we eat, the air we breathe, the water we drink—these are all fundamental building blocks of health. ASTHO works with our members and other public health professionals to maintain these essential components of wellbeing. Along with these core issues, environmental public health considers other pieces of our environments that impact our health: vectors of disease like ticks and mosquitoes, the built environments in which we live, and climate change. 

Addressing climate change is a key part of our agenda now and in the foreseeable future. Caring for the health of the environment around us is an important means of caring for our own health—a connection that is seen repeatedly in the resources below.

ASTHO manages several environmental health groups, including the State and Territorial Environmental Health Directors peer group, the State Tribal Liaisons peer group, the National Association of Vector-Borne Disease Control Officials, the State Health in All Policies Group, and the Climate Change Collaborative.  

With input from these groups, we develop documents, interactive platforms, and webinars to showcase the work that the members do on key environmental health areas.  

We also convene more specific, ad hoc workgroups if there is an environmental health issue that requires more focus. These groups have helped in the development of some of our products as well, like Public Health Confronts the Mosquito 2nd Edition. 

ASTHO also convenes the Environmental Health Policy Committee and has worked with the committee to develop policy statements for climate and extreme weather, health in all policies, and a general environmental health policy statement.
