Best answer: What percentage of human CO2 emissions comes from burning coal?

How much CO2 is produced from burning coal?

Coal’s most notorious byproduct is carbon dioxide (CO2). Every million BTUs released from burning coal releases an average of 208 pounds of CO2 (see note below). Since a ton of coal has 20.025 million BTUs, that means it creates 4,172 pounds of CO2 when it is burned.
