The work of the Transport Decarbonisation Alliance (TDA) is organised in Working Groups. Country, cities, regions, nonprofits, and company members of the TDA come together and exchange information on best practices, common challenges, and solutions. This approach enables TDA members and partners to work together on innovative pilot projects and on identifying actionable solutions to decarbonise transport.

Working Groups in the TDA are formed for a certain duration, with the goal to provide specific outputs and activities.  TDA members can suggest new topics as well as volunteer to lead and coordinate the work of a new Working Group.
