Workplace Charging Challenge: Ambassadors

The Workplace Charging Challenge enlists stakeholder organizations as ambassadors to promote and support workplace charging. Ambassadors, including Clean Cities coalitions across the country, are organizations that are knowledgeable about local incentives, best practices for workplace charging, and other aspects of plug-in electric vehicle (PEV) community readiness. Challenge partners can benefit from working with ambassadors in their region to promote PEVs and workplace charging. The directory below highlights Challenge ambassadors and the workplace charging resources they’ve developed. Ambassadors and other organizations aiming to promote workplace charging to employers in their region, can obtain resources from the Workplace Charging Outreach Toolkit.

Learn more about how your organization can benefit from joining the Challenge.
