Transport Task Group (TTG)

The Transport Task Group (TTG) was established by the G20 in order to:

  • build domestic support and enhance capability for action to reduce the energy impact of motor transport, especially heavy‑duty vehicles (HDVs);
  • identify and exchange best practices among G20 countries on the implementation of cost‑effective energy efficiency measures in the transport sector; and
  • conduct analysis and outreach to assess the opportunities, barriers, costs and benefits of HDV energy efficiency action, and subsequently recommend a course of action for participating G20 countries.

Why does transport matter for energy efficiency?
