The document outlines activities for WP.29’s 200th session on 17 November 2026 at the Palais des Nations in Geneva. WP.29 held its first session from 10 to 13 February 1953 and provides a global intergovernmental framework for development and harmonization of technical requirements for wheeled vehicles, their equipment and parts under the 1958, 1997 and 1998 Vehicle Agreements. The session marks an institutional milestone to reflect on international regulatory cooperation and recognize the community sustaining WP.29’s work. Recent work includes adoption of a new UN Regulation on laboratory measurement of brake emissions from light-duty vehicles in March 2026 and establishment of a new UN Global Technical Regulation containing harmonized safety provisions for Automated Driving Systems in June 2026.
