source: Domino Sugar
Of course, as Watts Up With That? details, table sugar (sucrose) is a carbohydrate with a chemical formula of C12H22O11. Meaning each molecule contains twelve carbon atoms, and thus by definition can't be "carbon free."
Yes, I know Domino is trying to claim its manufacturing process produces no net carbon emissions. So why not say "carbon neutral"? Because, obviously, green is hip, carbon ain't cool (heh) and a sucker is born every minute.
