The SGP30 sensor measures two different types of gases: volatile organic compounds (like hydrocarbons) and equivalent carbon dioxide (H2 level is used as a proxy for this). The sensor does some nifty real time baseline compensation to give you the most accurate readings, with just a 10 15% margin of error
