The TDA’s core contribution is to foster cooperation among countries, cities/regions and companies (the ‘3Cs’) toward carbon-free transport, accelerating action through synergy and interaction. The TDA 3C members have signed the TDA Charter and committed to:

• Make a public commitment to accelerate action to decarbonise transport to meet a net-zero emissions sector as soon as possible
• Share regular up-to-date information about their objectives, actions, progress and experiences in decarbonising transport
• Promote strategic direction, action guidelines and tools provided by the TDA ecosystem
• Contribute actively to the promotion of the TDA objectives
