Actually, green tea DOES contain caffeine, unless you buy green tea that has been de-caffeinated. Natural green tea contains caffeine.

Green tea and black tea is exactly the same product, it comes from the exact same leaves of the same tea tree. The only difference is in how it is prepared.

Green tea is tea leaves that are harvested fresh, hence "green", and dried quickly. Black tea is allowed to ferment and dry slowly, hence "black". Same plant, though, therefore same amount of caffeine.
