WORKSHOP 3: CLEAN VEHICLE AND CITY CENTRE TRANSPORT SOLUTIONS Interest in cleaner, less polluting vehicles and fuel has grown rapidly over recent years. This interest has been spurred by three factors: * Increasing awareness and concern regarding the environmental effects of vehicle use * The financial savings that vehicle operators can make by switching to cleaner vehicles * Increasingly stringent emissions legislation. Biomass is the only renewable source of transportation fuels. These renewable fuels, called biofuels, produce fewer emissions than petroleum fuels. The European Union is promoting the marketing of greener cars via a combination of binding and non-binding measures. Clean vehicles include low emission conventionally fuelled vehicles as well as those powered by alternative fuels. The production of such vehicles, generating less CO2 emissions, requires innovation in fuels, alternative power-train technology, noise reduction and new materials. Overall, the European Union’s aim is to reach - by 2010 at the latest - an average CO2 emission figure of 120 g/km for all new passenger cars marketed in the Union. Presentation of the most important technologies and fuels is given below. Source: European car industry and future challenges With 42% of global production coming from the EU in 2002, the region has the largest single market for passenger cars in the world and is well positioned to leverage economies of scale and scope. But one major challenge lies in the advantage Japanese car makers have gained in developing environmentally friendly technologies, “most prominently the development of new technologies/fuel combinations, including fuel cells”. As a consequence, the report notes, “RD objectives in the automative industry should be directed towards developing environmentally friendly vehicles”, in particular finding the “adequate technology/fuel solutions” to ensure long-term security of supply. Biofuels (I): market share and makin
