Isn't it true that the mercury *in* the CFL is less than the mercury
release by burning the additional coal that would be required if an
incandescent lamp were used instead?

Yes, but only if the power is generated by coal-fired power stations.
In France, where the majority of electrical power is generated by
nuclear plants, and in Norway, where near enough 100% is
hydroelectrically generated, fluorescent lamps increase the amount of
mercury released into the environment.
