The cities of London and Coventry suffer from increasing air pollution and traffic problems. The largest participant in the ZEUS project, the city members of the consortium comprising several London boroughs and the City of Coventry are committed to their traffic and emission strategies, but market obstacles have restrained the use of ZEVs (zero emission vehicles) and LEVs (low emission vehicles).
This situation is now beginning to change, partly because fleet managers are aware that there will soon be a need to meet EURO 3 emission standards, and partly because an improvement in air quality is widely recognised as essential to the quality of life and prosperity of our cities. In the UK, ZEUS is the first purchasing group to be formed for ZEVs, LEVs and related infrastructure. The potential for early expansion of the project is attracting the interest of the technical press.
The main fuels being proposed for use in this project are CNG (natural gas) and electricity, but the project is open to consideration of other fuels such as LPG (liquefied petroleum gas). There are firm proposals for eight new CNG stations and at least eight new fast charging stations. These, and other planned infrastructure, will serve the fuel needs of some hundreds of new or converted vehicles. They range from low-floor CNG buses, CNG taxis, CNG/LPG light vans and refuse freighters, electric cars and minibuses to light mobile machinery. In addition, the consortium aims to attract third-party purchases for over two hundred vehicles which will not be directly funded by ZEUS but will be able to take advantage of lower vehicle prices.
The vehicle and infrastructure programme is supported by a wide variety of other measures designed to reduce energy use and pollution. These include a fleet management telematics project, ride-share campaign, car sharing, "libre" easy access rent scheme, improved driver training, improved passenger information, trip substitution, increased public transport use, plus parking and access initiatives. Evaluation of these measures include surveys of customer satisfaction and user accessibility, and an "ecofeed" initiative.
The importance of education and public awareness cannot be overstated, and will be an integral element of all aspects of the work. Publicity and awareness will, therefore, also be promoted through a range of campaigns and events, including an interactive science exhibition which will be made available to other participating cities.

Horizontal issue: Technical evaluation of vehicles
The London/Coventry consortium is responsible for leading the technical evaluation of vehicles by providing all partner cities and businesses with a standard monitoring programme. This is being developed by the Motor Industry Research Association (MIRA), in consultation with partners, and with implementation from the summer of 1997 onwards. Furthermore, research is being carried out by Southwark in conjunction with the University of Greenwich to provide a review of existing data on the environmental impact of zero emission vehicles and low emission vehicles in the first year of ZEUS, and thereafter to develop a model for life-cycle analysis.

THE DIFFERENT PARTIES INVOLVED ARE:
London Borough of Sutton (coordinator), London Borough of Camden, London Borough of Merton, London Borough of Southwark and the City of Coventry. In association with: Centrica, Powergen (energy companies), MIRA (The Motor Industry Research Association), London First and The Energy Savings Trust. Other UK purchasing groups are being actively encouraged to procure vehicles by Southwark, Coventry and The Energy Savings Trust.
