The project follows a multi-level approach:

At the ASEAN level, TCC advises and supports the implementation of the KLTSP. Input and support for the development of this plan — which includes a specific chapter on sustainable transport for the first time — was given by TCC I. The project works closely with relevant ASEAN working groups such as the Land Transport Working Group (LTWG) and the Transport Facilitation Working Group (TFWG).

On a national level, TCC supports respective ministries of the participating countries to link their national strategies and action plans for energy efficiency and climate protection in transport to the KLTSP and support implementation measures thereof. To support the process and the implementation of the KLTSP on the regional and national level, expert working groups on fuel efficiency and sustainable transport indicators are established and meet regularly.
