A chief heat officer, or CHO, is a municipal public servant focused on combating the dangers of
extreme heat and reducing
urban heat island effects.
Most chief heat officers are hired by cities, counties, and other forms of local government. The position emerged in the early 2020s, with several cities in hot climates appointing chief heat officers to try to mitigate the increasing effects of
climate change by increasing shade, providing for
cooling centers, planting trees, and coordinating anti-heat work.[1][2][3] Early heat officer positions were created in
Los Angeles,
Miami-Dade County,
Melbourne,
Athens, and
Freetown.[4] The initiative to create the positions was organized by the
Atlantic Council's
Adrienne Arsht-
Rockefeller Foundation Resilience Center.[5][6]
