UC San Diego's Earth Month 2019

International Earth Day is April 22, but UC San Diego inspires the community to take sustainability action throughout April with a variety of events, including the Cool Campus Challenge, tree planting, green TED-style talks, fairs, annual Sustainability Awards and other events that will help you green your lab, office, residence hall, apartment and home.

Are you up to the challenge?

This April, pledge to take simple steps at work and at home to lower your energy and water use, reduce waste and live a healthier.


Sign up for the Cool Campus Challenge starting March 15 and help UC San Diego win the coveted title of Coolest UC Campus!

Earn Points and Prizes

From April 1-26, you and any team you create (departments, offices, clubs, houses, etc.) can pledge online to take sustainability actions and earn points for yourself, your team and UC San Diego. You can earn points by attending UC San Diego’s Earth Month events.

The top UC campus, team and individual will win awards and we’ll recognize top UC San Diego point earners with prizes like solar-powered mobile device chargers and reusable lunch kits. Share what you’re doing on social media using #CoolCampusChallenge to be featured online. Get details
