2002年，广州市推进城市公共交通车辆清洁能源应用工作经过3年多的不懈努力，取得明显成效。至2006年底，全市LPG公交车达6400台，占公交车总数的80% ； 16000台出租车完成LPG改造工作。目前全市各类在用公交、出租车型基本都有配套的LPG发动机和设备，几个主要车型均实现LPG整车制造出厂。在推进这一民心工程过程中，广州市成功解决了LPG清洁能源运用于大功率发动机的技术难题，LPG单燃料城市客车不仅在数量上是世界第一，而且技术水平和使用管理水平也达世界领先水平。

　　2007年，广州市环保权威机构抽样80台LPG公交车进行尾气排放检测，结果显示：广州市LPG公交车CO（一氧化碳）的排放接近“0”；HC（碳氢化合物）在高怠速时仅有北京标准的三分之一；低怠速时也仅有北京标准的40%。根据广州市公交出租车排放量占全市机动车排放总量的比重48%～50%的情况计算，广州市公交出租车全面使用LPG后，每年机动车尾气排放污染物一氧化碳（CO）、碳氢化合（HC）、氮氧化物（NOX）和颗粒物（PM）总量将分别减少22000吨、2430吨、1779吨和417吨。

■Clean Energy for Public Transport and Taxi Tehicles

　　Remarkable achievements have been made through three years' unremitting efforts, starting from 2002, to promote the application of clean energy for public transport in the city. By the end of 2006, over 6,400 public transport vehicles, 80% of the total, had been LPG powered, and 16,000 taxis had converted to LPG.

　　Currently, most public transport vehicles and taxis have been equipped with LPG motors and some major types of vehicles are even ready-made LPG-powered vehicles right off the assembly line. Besides, the city has successfully tackled the technical problem of applying LPG to high power engines, which makes it the world's No. 1 in terms of the number of LPG-fuelled public transport vehicles as well as technical and managerial levels.

　　In year 2007, the city's environment authority carried out an exhaust emission test on 80 LPG-powered buses and the result showed that the CO emission was close to zero. And the HC emission was only one-third of the Beijing Standards at high idle speed and only 40 percent of the Beijing Standards at low idle speed. As the total emission of public buses and taxis accounts for 48-50 percent of a city's total vehicles, the emission of CO, HC, Nox and PM
will be reduced by 22,000, 2,430, 1,779 and 417 tons respectively after the application of LPG fuel.
