Ozone is one of the highly reactive gases, which is photo chemically active. It is composed of three atoms of oxygen (O3) and its role depends on its location in the atmosphere. This gas plays a different role in the lowest two layers of the atmosphere, known as the stratosphere and troposphere. In the stratosphere, above the tropopause about 90 percent of the ozone protects life on earth from the sun's dangerous ultraviolet radiation.

While Honda has just introduced its hybrid Civic in India, more such cars are being produced overseas (like Toyota's Prius).
