Each country targets the minimization of green house gases. Green house gases are those gases that are known to contribute towards global warming or greenhouse effect such as CO2, N2O,and water vapour. This is the rationale behind the move by many countries towards the substitution of fossil fuels by cleaner fuels. Fossil fuels produce carbon IV oxide which is known to lead to global warming. Greenhouse gasses impact the environment negatively by raising the temperature of the earth.
