In a powerful move to advance clean energy and environmental equity, the Greater Washington Region Clean Cities Coalition (GWRCCC) is proud to host its Inaugural Earth Day 5K Walk, Alternative Fuels Display, and Green Expo on Saturday, April 19, 2025, from 10:00 AM to 3:00 PM on the iconic National Mall in Washington, D.C.
As the region’s foremost advocate for sustainable transportation and clean energy, GWRCCC is inviting families, community leaders, businesses, students and sustainability enthusiasts to celebrate Earth Day with action. This free, public event brings together a powerful coalition of voices, technologies and solutions in support of a cleaner, greener tomorrow.
A Celebration of People, Planet and Progress
The Earth Day 5K Walk is more than just a scenic loop around the U.S. Capitol and Washington Monument — it’s a call to action. Participants will walk in solidarity to raise awareness for clean energy adoption, green job creation, and environmental justice in underrepresented communities.
“Earth Day is about more than reflection — it’s about mobilizing our community for action,” said Antione M. Thompson, Executive Director of GWRCCC. “This event represents our ongoing commitment to accelerate the transition to clean fuels, support green workforce development, and empower communities disproportionately impacted by pollution and climate change.”
A Green Expo Like No Other
Alongside the walk, the Green Expo will feature cutting-edge technologies, local innovators and national stakeholders working at the intersection of energy, health and policy. Guests can explore hands-on exhibits, connect with vendors and learn about electric vehicles (EVs), hydrogen fuel cell transportation, biodiesel, propane and natural gas innovations — all designed to reduce greenhouse gas emissions and promote energy resilience.
From test-driving EVs to chatting with public health experts about air quality, the Green Expo offers a fully immersive, family-friendly experience. Expect live music, refreshments, giveaways and activities for kids and adults alike.
Alternative Fuel Vehicle Showcase
One of the key highlights of the day will be the Alternative Fuels Display, featuring a wide array of clean transportation vehicles — from electric school buses and hybrid police cruisers to propane-powered delivery vans and hydrogen trucks. Local fleets and partners will be on-site to discuss how these technologies are already making an impact in D.C., Maryland and Virginia.
GWRCCC: A Regional Force for Clean Cities
Since its inception, GWRCCC has worked to advance alternative fuel use and reduce petroleum dependency across the District of Columbia, Northern Virginia and Southern Maryland. As part of the U.S. Department of Energy’s Clean Cities Program, GWRCCC brings together public and private stakeholders to solve some of the region’s most urgent energy and environmental challenges.
Under the leadership of Antione Thompson — a former New York state senator and national green policy expert — GWRCCC has grown into a regional thought leader on clean transportation, climate equity and workforce development. The Earth Day 5K Walk and Green Expo reflects the coalition’s growing influence and dedication to inclusive, action-oriented sustainability.
