Join us for the statewide 2025 Colorado Sustainability Challenge (CSC), a two-week, hackathon-style event designed for anyone passionate about solving problems, teaming up on an idea and having fun in the process of building a solution to impact sustainability. CSC is a hybrid event that takes place at CU Boulder and participating affiliate institutions. Participants come from all academic disciplines—ranging from the Humanities to STEM—and have a shot at winning a share of $17,000! Open to all students, faculty and staff at Colorado Front Range colleges and universities. Learn More and Register

Sustainability problems can be solved with —or without— technology, and you can jump in solo or bring your friends and form a team. Whether you have an idea or are someone eager to help those ideas become real, this is an event you won't want to miss!
