hb4493/introduced-in-house.txt119 HR 4493 IH: Climate Health Emergency Act of 2025U.S. House of Representatives2025-07-17text/xmlENPursuant to Title 17 Section 105 of the United States Code, this file is not subject to copyright protection and is in the public domain.I 119th CONGRESS 1st Session H. R. 4493 IN THE HOUSE OF REPRESENTATIVES July 17, 2025 Ms. Dexter (for herself, Ms. Velázquez , Ms. Norton , Ms. Ansari , Ms. Randall , Ms. Barragán , Ms. Jayapal , Mr. Ruiz , Mr. Schneider , Ms. Simon , Mr. Tonko , Ms. Tlaib , Mr. Carbajal , Mr. Bell , and Mr. Thanedar ) introduced the following bill; which was referred to the Committee on Energy and Commerce A BILLTo direct the Secretary of Health and Human Services to declare a public health emergency in connection with health risks associated with climate change, and for other purposes.1.Short titleThis Act may be cited as the Climate Health Emergency Act of 2025 .2.FindingsCongress finds the following:(1)In the past decade, the Secretary of Health and Human Services has declared or renewed a public health emergency 120 times. Of those declarations and renewals—(A)66 were related to extreme weather events;(B)14 were related to COVID–19;(C)2 were related to earthquakes;(D)2 were related to Mpox;(E)32 were related to the opioid crisis; and(F)4 were related to Zika.(2)A preponderance of evidence shows that climate change is driving or, at a minimum, exacerbating extreme weather events and the transmission of infectious diseases. Therefore, climate change can be linked to more than half of all public health emergency declarations over the past decade.(3)For this reason, entities (including the World Health Organization) have identified climate change as the most significant health threat of the 21st century. Yet the public health infrastructure of the United States remains woefully unprepared to meet the increased demand that climate-related public health crises continue to drive.(4)The United States bears a moral and strategic responsibility to confront climate-related public health crises with the urgency such crises demand. To protect communities in the United States, and the most vulnerable individuals within such communities, the Nation must mobilize Federal resources, enable data sharing, exercise emergency authorities, and coordinate across agencies to build a public health system that is resilient to the intensifying threat of climate change.3.Declaration of public health emergencyThe Secretary of Health and Human Services shall declare a public health emergency under section 319 of the Public Health Service Act ( 42 U.S.C. 247d ) in connection with health risks associated with climate change.
