MIT is home to many groups and individuals who are working to better understand the science, economics, and politics of global climate change and sustainability. We are proud to represent some of their work on OCW. In honor of Earth Day, here’s a hand-picked selection of OCW’s best courses on these topics, organized around four themes: science foundations, new technology and engineering solutions, the continuum of economics-business-policy-politics, and perspectives from the humanities.

Science Foundations

Technology and Engineering Solutions

Economics, Business, Planning, & Politics

If OCW courses have helped you make a difference — like these Haitian solar energy entrepreneurs and a polar research scientist — we’d love to hear about it.  Please send us your feedback!
