What is Green Fair?
Stroll local exhibits and learn innovative ways to live sustainably and take climate action. Dozens of nonprofit, governmental, and other exhibitors will be on hand to answer your questions. Find resources and communities for sustainable action, including: the circular economy, solar technologies, green transportation, plant-based foods, climate resiliency, environmental education, clean water protections, and energy waste reduction.
Downtown Main Street will be activated with Green Fair exhibitors from 5-8pm. Enjoy a wide variety of interactive demonstrations, see the latest in tech innovations, and enjoy great music! Bring an upcycled t-shirt or tote bag to use at the sustainable screen printing station, get ready to answer trivia questions and win fun prizes, and join the bike parade for the planet. Stop by the Library Lane Lot, 343 S. Fifth Ave, from 2-6 pm to learn about a variety of alternate forms of transportation. Test drive the newest tech in electric vehicles, take a spin on an e-bike, learn about clean last-mile delivery transport, and test your traffic knowledge with the transportation team.
Plus, discover the latest advancements and interact with cutting-edge technologies and companies in the region by checking out Tech Trek on Liberty Street (between Division and 4th) from 1-5pm.
