The Center for Climate, Health and the Global Environment (C-CHANGE) bridges the gap between science and the public, helping turn the research and expertise of faculty and students at the Harvard T.H. Chan School of Public Health into actions that all can take to make vast improvements in public health and the environment just as the School has done over the past century.  C-CHANGE uses the best science as the key driver to address climate change and sustainability—now, and for generations to come.
