Environmental science and engineering is an interdisciplinary program with the common goal of understanding, predicting, and responding to human-induced environmental change.

Environmental scientists at Harvard address environmental issues such as global warming, stratospheric ozone depletion, and local and regional air and water pollution. This work requires perspectives from a diverse set of scientific disciplines, including atmospheric physics and chemistry, oceanography, glaciology, hydrology, geophysics, ecology, and biogeochemistry. 

Graduate students in environmental science and engineering work with faculty researching:
