pollution

WITH an increasingly short supply of oil, it will be inevitable that the traditional internal combustion engine will be redesigned to not only save fuel but also reduce air pollution from cars. Although the technology of the internal combustion engine in China lags nearly 20 years behind that of developed countries, the gap in cars that are more environmentally sound, such as electric ones, is smaller. The following are some examples of what other countries have done with respect to environmental protection. Singapore There's a reason Singapore has few traffic jams. Ten years ago the island nation implemented regulations in downtown areas that prohibit drivers who have not paid certain road fees. An automatic charging system monitors traffic and records car license plate numbers and times so as to calculate a road fee the car owner must pay. Germany Germany has a policy which gives tax cuts to owners whose cars meet the emission standards of the German III Standard. Tax breaks range from US$127 to US$600 if a car reaches the IV standard. Such measures are an incentive for consumers and manufacturers alike to focus more on environmental protection. Britain A survey conducted by the British Automobile Association indicates that exhaust emission from the 23 million cars within UK borders was lower than that from its 500,000 buses and trucks. Officials from the Ministry of Transport want heavy vehicles to also be held to the same low exhaust emission standards as cars. Various measures have been taken to limit the number of cars on the road, thus reducing air pollution, by raising parking fees and abolishing free parking lots at big companies and public places in the city proper. Japan Low-pollution cars have been promoted in the Japanese market since the end of 1997 in response to the greenhouse effect. The number of such vehicles on the road has reached 9,000, with 3,726 utilizing a combination of petrol and electricity and 2,700 with fully electric motors. These newer hybrid cars offer the same level of engine performance as conventional ones and can go up to 2,000 kilometres without being recharged.

in order to avoid pollution we should prefer vehicals run through gas.so that we can decrese pollution.but we may have gas scarcity.if we want one we should lose one.
