Electric School Bus Ambassadors

WRI's Electric School Bus Initiative is proud to partner with the Electric School Bus (ESB) Ambassadors below to support school districts as they transition to electric school buses.

ESB Ambassadors are dedicated individuals across the country using their experience in student transportation and school bus electrification to help facilitate an equitable transition to ESBs.

ESB Ambassadors share their expertise at pupil transportation and other events, in online webinars, through written articles and more. They build connections with peers in student transportation and other fields, answer questions and provide free resources to help other districts go electric.  

WRI’s Electric School Bus Initiative is partnering with these Ambassadors to support districts across the country in making a successful transition to electric school buses, while centering equity in both process and outcomes.

Are you ready to help other districts get on board with electric school buses? Reach out to us to learn about becoming an Ambassador – and amplify your impact! Please contact Jessica Wang at jessica.wang@wri.org.
