In addition , 5carbon dioxide emission which is the end increase of burning fuel such as torpedo , accounts for 80 emissions . Carbon dioxide is the major greenhouse gas , with global thawing potential . Needless to explain , development should no be measured quantitatively , that is by the number of cars that are red to and fro the streets of the cities .
