Easy enough to
find: "Most carbon dioxide — about 97 percent — comes from natural sources. That's roughly 300 billion metric tons per year of CO2 gas from breathing animals, decaying plants, forest fires, volcanic eruptions and other naturally occurring phenomena.
Human activities, like driving cars, burning coal, farming, industrial production and other practices, account for 3 percent, or about 8 billion metric tons of carbon dioxide production per year."
Of course, what is not disclosed is that these are just estimates based on models, but they are probably broadly accurate.
