Case Study: EARTHDAY.ORG achieves 100 million reach on Earth Day’s 50th anniversary with NationBuilder

EARTHDAY.ORG reaches 100 million supporters on Earth Day’s 50th anniversary

EARTHDAY.ORG, facing the sudden loss of thousands of planned in‑person activities for Earth Day’s 50th anniversary due to the COVID‑19 pandemic, needed to centralize scattered supporter data and rapidly pivot to a digital-first strategy. To consolidate their CRM and support a large-scale online mobilization, EARTHDAY.ORG implemented the NationBuilder platform.

NationBuilder delivered a unified CRM, built‑in action pages and embeddable forms that let the team quickly stand up “Earth Day Live” — a 12‑hour livestream with 1,681 registered digital events — while enabling seamless collaboration across departments. The platform helped drive measurable impact: the campaign reached 100 million people worldwide, streamlined data sharing and volunteer coordination, and allowed EARTHDAY.ORG to execute the anniversary entirely online thanks to NationBuilder.
