In addition to Bloomberg Philanthropies’ five areas of focus – public health, arts and culture, the environment, education, and government innovation – Bloomberg continues to support projects of great importance to him, including his alma mater, Johns Hopkins University. He served as chairman of the board of trustees from 1996 to 2001, and the university’s School of Hygiene and Public Health is named the Bloomberg School of Public Health in recognition of his commitment and support. In 2018, he gave $1.8 billion to allow Johns Hopkins to permanently accept and enroll students without regard to their ability to pay – the largest gift in the history of American higher education.

Bloomberg has continued to be one of America’s most fearless and effective voices on urgent issues including climate change, gun violence, and public health. The gun safety group he helped found, Everytown for Gun Safety, now has more than six million supporters and is the largest coalition of Americans fighting for common-sense gun laws. His partnership with the Sierra Club has shut down more than half the nation’s coal-fired power plants and replaced many of them with clean energy, saving many lives and creating many new jobs.

Bloomberg served as the UN Secretary-General’s Special Envoy for Climate Action, charged with galvanizing the efforts of local and regional governments, businesses, and civil society. He also served as the World Health Organization’s Global Ambassador for Noncommunicable Diseases and Injuries, supporting the organization’s push to achieve UN goals of reducing premature NCD deaths by one-third by 2030 and halving the number of road deaths and injuries by 2020.
