The burial of a body that has not been embalmed, which is then placed in a biodegradable casket, shroud or with no covering is green.
A GREEN BURIAL CAN TAKE PLACE IN A SPECTRUM OF GREEN CEMETERIES
Hybrid - When a conventional cemetery sets aside an area for burials without the requirements of vaults and accepts eco friendly burial containers. The majority of the cemetery probably contains to operate using modern practices.
Low Impact - A low impact cemetery prohibits the use vaults and non biodegradable caskets or other materials. It also adopts a pest management policy that prohibits the use of pesticides (unless absolutely necessary to eliminate non-native species).
Natural - Goes further than low impact by maintaining and furthering the natural landscape. (No mowing or watering, the landscape is allowed to exist in its natural state with native plant species - think old time church cemeteries where people were buried without ongoing maintenance of the cemetery.)
Conservation - In this case, the cemetery acts as a land conservation tool. All the burials are natural and the land is protected by a conservation easement. Many times the land is reclaimed from previous uses (farming or industrial) or saved from impending development. A conservation cemetery meets the highest “green” standards and has other policies that respect the land and allow burial to rejoin the circle of life!
