http://www.w3.org/ns/prov#value | - the 6 GT of CO2 produced annually-how is that calculated? i have read sources stating that 12% of petroleum products go into ???non-fuel??? uses, mostly including plastics, solvents, lubricants, and other sources which remain sequestered. so if 6 GT is calculated from the gross amount of petroleum sold, 5.28 GT is closer to the truth. (720 BILLION tons less, in dr. evilspeak)
