The UNECE Transport Division has been providing secretariat services to the World Forum for Harmonization of Vehicle Regulations (WP.29) for more than 50 years. The World Forum has incorporated into its regulatory framework the technological innovations of vehicles to make them safer and more environmentally sound.

In addition to acting as secretariat to the World Forum, the Vehicle Regulations and Transport Innovations section serves as the secretariat of the Administrative Committee for the coordination of work, and of the Administrative/Executives Committees of the three Agreements on vehicles administered by the World Forum.
