Medical Advocates for Healthy Air


Medical Advocates for Healthy Air (MAHA) is a statewide network of medical and health professionals leading the call for cleaner air. MAHA members learn about the health impacts of air quality so that they can help their patients and advocate for strong, clean air policies.

Charged with the responsibility to prevent disease whenever they can, medical and health professionals have an important role to play in protecting their patients from air pollution. Trusted sources of information who see the impact of air pollution and climate change on the health of their patients, the nurses, physicians, respiratory therapists, public health educators and other professionals participating in MAHA can make an impact with a unified voice.

MAHA works closely with partners such as medical schools, healthcare organizations, research institutes, government agencies and other environmental and health advocates in order to ensure we are engaging with our members and our policy makers as effectively as possible. Committed healthcare leaders representing diverse professions who serve on MAHA’s Advisory Board help with outreach and engagement strategy. If you are interested in having MAHA partner with your organization, please contact us!

MAHA staff, members and partner organizations visit NC policymakers to discuss the importance of clean air to health.

As a MAHA member, you will have access to healthy air trainings, information on research and tools that can help patient care, and convenient opportunities for communicating with policymakers.

It does not have to take much time to be an effective advocate because MAHA helps you fit advocacy into your schedule. Advocacy opportunities range from simply adding one’s name to a sign-on letter, to meeting with a legislator or testifying at a policy making hearing. You can choose the opportunities that are right for you.

Our email communications include a monthly newsletter, invitations to events such as the NC BREATHE Conference, trainings or local meetings, and action alerts when we need your help to promote a clean air policy — or to prevent a policy that will harm our air quality.
