Using mass transportation systems is an ideal way for you to do your part by helping to save the environment. Mass transportation reduces the number of vehicles on the road, thereby reducing the consumption of fossil fuels. Transportation is considered to be responsible for 60 to 90% of urban air pollution. Using greener forms of mass transportation will help in reducing air pollution and climate change emissions. Various countries are promoting the use of mass transportation facilities due to this. Iceland for example is promoting the use of Hydrogen run buses. This comes after the country made significant strides in harnessing hydroelectric and geothermal energy.
In New York, school buses have been refitted to ensure that they are eco friendly in nature. The buses have been retrofitted with diesel oxidation catalysts and crankcase spiracle filters which help to reduce that air pollution that is emitted by these buses. This was part of the Environmental Protection Agency’s (EPA) drive for a more eco friendly school buses. New York also has hybrid electric buses.
