Continuing air pollution problems from vehicle-related pollution have been stimulating innovative pollution control approaches around the world. As these approaches are implemented, steady progress in reducing certain air pollution problems is occurring. An example is the experience in Southern California's Los Angeles Basin, which has had the most aggressive motor vehicle pollution control programme in the world over the past forty years. From 1955 to 1993, peak ozone concentrations were cut in half. The number of days on which Federal ozone standards were exceeded fell by 50 % from the 1976-78 time frame to the 1991-93 interval. Further, the average annual number of days above the Federal carbon monoxide standard fell from 30 to 4.3 during this same period, and lead levels are now 98 % lower than in the early 1970s. Most remarkably, this achievement occurred while the regional economy outpaced the national economy in total job growth, manufacturing job growth, wage levels and average household income. In short, a strong focus on environmental protection is not only compatible with strong economic development, they seem to be mutually reinforcing. The first is the growing concern with particulates. As the available health information continues to raise more and more serious concerns regarding diesel particulates, they will need to get more attention in the future. As stated by the UK government in response to the reports from the Committee on the Medical Effects of Air Pollutants and the Expert Panel on Air Quality Standards, 'the central element of any strategy will concentrate on technology based measures to secure further long term abatement of vehicle emissions, particularly from diesel vehicles'. Secondly, the increasing problem of C02 emissions from the transport sector cries out for more innovative approaches. As recently noted by the European Commission, 'Under a 'Business as usual' scenario, CO2 emissions from cars are expected to increase by about 20 % by the year 2000 and by about 36 % by the year 2010 from 1990 levels. The road transport sector has stood out in recent years as one of the few sectors in the Union experiencing C02 emission growth'.
