The Earth Action Committee now meets monthly for year-round action - contact us to get involved!​ 
Sustainable Resilient Longmont was founded in 2015 to create a fun Earth Day event for Longmont that would inspire hope and empower positive change to address the often overwhelming environmental challenges of our time. Since that first event, the Longmont Earth Day Celebration has grown to become one of Boulder County's biggest Earth Day events and an annual tradition for many Longmont families. We have maintained one clear message throughout the years: There is hope for the future of humanity and our amazing planet if we work together on solving global challenges at a local level.
