Comparing CO2 emissions to CO2 levels Skeptical Science
The atomic mass of carbon is 12, while the atomic mass of CO 2 is 44. Therefore, to convert from gigatonnes carbon to gigatonnes of carbon dioxide, you simply multiply 44 over 12. In other words, 1 gigatonne of carbon equals gigatonnes of carbon dioxide. Atmospheric CO 2 levels are expressed in parts per million by volume (ppm).
