An Australian cemetery has unveiled plans to take the carbon out of cremations by offering new green funerals to help combat global warming. On the day Australia's formal ratification of the Kyoto Protocol on Greenhouse emissions comes into force, the Centennial Park cemetery in the South Australian state capital of Adelaide said it had studied the carbon impact of burials and cremations. While cremations initially produce more carbon emissions than a burial, cemetery chief executive Bryan Elliott said over time, burials ended up producing about 10% more greenhouse gas. "If we plant one tree for every service, either burial or cremation, we will more than offset the carbon emissions,' Elliott said.
