At 0.3%, carbon dioxide is the least common gas in the Earth's atmosphere. This is in no way indicative of its lack of importance, since carbon dioxide is the primary source of life on earth and its concentration on earth's pre-industrial atmosphere has been regulated by photosynthetic organisms and is a principle supplier of greenhouse gases.
