<human>:  I'm looking to make a career change in the next year and I'm gathering information on the best graduate programs in sustainability. Can you provide me with information on some of the top universities offering this type of degree?
<bot>: Some of the top universities offering graduate degrees in sustainability include Stanford University, Harvard University, Yale University, UCLA, Columbia University, University of Michigan, Georgia Institute of Technology, and University of Massachusetts-Amherst. Each of these schools offer programs that cover topics ranging from environmental conservation to energy systems and green technologies.
