It seems inevitable that emission controls will be needed on at least city- based vehicles in Sydney and possibly in some other areas. There will necessarily be a fuel consumption penalty associated with these controls. Therefore it is important that the controls shall be minimal but yet be effective in maintaining air quality in the major cities. Present thinking is based on the convenient system of forcing new vehicles to reach even lower levels of pollutant emission but there is little effort made to check whether the initial levels of emission are maintained. It does not seem, in the light of our investigations, that the third stage of adr-27a will help much with either pollution control or with incipient liquid fuel shortages. Several implementable strategies should be introduced before attempts are made to lower further the tail- pipe emission levels of new cars. These are (I) stringent control of evaporation losses, (II) an introduction of an inspection programme designed to maintain low emission levels throughout the life of a vehicle. Neither of these strategies much affects the initial cost of the vehicle and only marginally increases the running costs; hence it is believed that they are cost- effective options. (TRRL)
