Want to help make our campus greener? If you do, the Harvard University Office for Sustainability might want to pay you for the effort. For the second year in a row, HUOS is offering Sustainability Grants ranging from $500-5000—and any undergraduate or grad student is eligible to apply. The application, which is due by Oct. 25, can be found on the HUOS website, along with more logistical details about the program.

Previous recipients of the grants have held waste-free barbecues, planted gardens, and created bike-sharing programs. Some grants were used to encourage composting and others to decrease waste in science labs around campus. What ideas do you have to change campus for the better?
