Cremation uses far fewer resources than almost any other disposition option but it also has an environmental
impact and "carbon footprint." Cremation burns fossil fuel and some older cremation facilities can use
significantly more energy compared to newer ones. Mercury is also emitted when a person with dental amalgam
fillings is cremated, though just how much is widely debated. The GBC has recently begun to certify cremation
disposition programs that create or protect habitat. We will also be requiring that mercury pollution be mitigated
by our approved cremation facilities by 2010 when cost-effective technologies are expected to be available.
