Later (1992), the UK Government signed Agenda Item 21 of the Rio de Janeiro UN Summit Conference about integrating developmental and environmental considerations in planning, and a road traffic reduction private members bill attained Royal Assent in 1997. This was followed by a rehashing of the statutory development plan system in 2000 and the introduction of composite local service boards into the planning system in 2005 (including police, fire and rescue services, health and ambulance services, education and welfare services, and employment and housing services); planning applicants had to submit 'Access and Design Statements' with their planning applications demonstrating they had taken all highways and transportation considerations into account, and additional 'Transport Statements' if proposed developments exceeded particular thresholds. This spawned new interest in the design of public places to improve conditions for pedestrians and cyclists, and for users of public transport and car-sharing clubs, to curtail carbon emissions.
