We encourage all eligible students with an interest in sustainability to submit an application to Sustainable Summer. You must be a high school student at least 15 years of age and no more than 18 years of age on the program start date to participate. For example, if you turn 15 on June 1st and the program start date is June 28th, then you are eligible. If you turn 15 on August 1st you would be ineligible. Graduated seniors are eligible to participate in our leadership expeditions (although not our leadership academies).
