Independently, oxygen and nitrogen are not greenhouse gases (though N2O, NO and NO2 are greenhouse gases). The most important greenhouse gas is carbon dioxide. Methane, althou â¦ gh found in quite low concentrations is also important because of its proportionately greater effect.here are several gases that are classed as greenhouse gases.    They are:   water vapor  carbon dioxide  ozone  methane  nitrous oxide  CFCs     Energy â¦ from the sun heats the earth's surface and atmosphere, which  drives the earth's weather and climate.
