Burning Fossil Fuels is the largest source of CO2. Most of this comes from gasoline and diesel engines, but not all. A large majority of CO2 comes from coal burning electric power plants.

I'd definitely say that the methane (a more potent greenhouse gas than CO2) released by cows (humans do keep them as livestock, so I think it's a fair answer) is one of the larger sources of greenhouse gasses contributing to global warming...As for CO2 specifically, it's got to be fossil fuel usage.
