In March 2000, WP.29 became the World Forum for Harmonization of Vehicle Regulations (WP.29). The objective of WP.29 is to adopt and follow measures to harmonize or develop technical rules on vehicles around the world. These rules, which provide uniform conditions for regular technical inspections and strengthening economic relations around the world, are designed to improve vehicle safety; – to protect the environment; – to promote energy efficiency and improve anti-theft performance. WP.29 currently manages three UN agreements, Indeed:1. United Nations agreement of 1958 on the adoption of uniform technical rules for wheeled vehicles, equipment and parts that can be mounted and/or used on wheeled vehicles and the conditions for mutual recognition of permits issued on the basis of these provisions;2. 1998 agreement to establish comprehensive technical rules for vehicles, equipment and wheeled parts that can be mounted and/or used on wheeled vehicles3.
