The bill instructs the New Hampshire Department of Health and Human Services to create a climate and health protection program to address health threats linked to environmental changes. The program's responsibilities include collecting and analyzing data on the health impacts of various environmental factors such as high heat index days, vector-borne illnesses, flooding, rising sea levels, intense storms, air quality issues, and longer pollen seasons. The department is also tasked with planning and implementing strategies to prevent and respond to these health threats, developing educational resources for residents, alerting the public to impending environmental crises, and coordinating with other state agencies and organizations.

The implementation of the program is contingent on the availability of non-state funding sources, as no general funds will be appropriated for it. The department is directed to seek grants, federal funds, and accept donations to administer the program. The bill also requires the department to advise legislators and executive officers on policies to protect against health threats due to environmental changes and include findings in an annual report. The fiscal note indicates that the program's estimated costs will be up to $156,500 in FY 2025, up to $172,200 in FY 2026, and up to $175,700 in FY 2027, with funding expected from federal funds, grants, or other non-general fund sources. The bill will take effect 60 days after its passage.
