In its purest sense, a green burial -- also called a natural burial -- entails wrapping an unembalmed human body in an eco-friendly, biodegradable shroud and burying the body in a natural setting in a manner that creates the least impact on the environment. In current practice around the world, however, a green burial can comprise one of many "shades of green."
Lacking a uniform standard or definition, "being green" is currently in the eye of the beholder concerning the burial of a deceased human being. This article explores some of the differences in the various forms of bodily disposition and the options available to help you determine if green burial is right for you -- however you wish to define it.
Pick Your Shade of Green
According to the National Funeral Directors Association (NFDA), a not-for-profit trade group representing funeral service professionals, a green burial occurs when "the body is buried, without embalming, in a natural setting; any shroud or casket that is used must be biodegradable, nontoxic, and of sustainable material; traditional standing headstones are not permitted. Instead, flat rocks, plants or trees may serve as grave markers."
NFDA adds that green burial "may also simply mean burial without embalming, in a biodegradable casket without a vault, when permitted by a cemetery."
The Green Burial Council (GBC), a non-profit organization that encourages environmentally sustainable deathcare, takes the standard of a green burial further, however: "Green burial is a way of caring for the dead with minimal environmental impact that furthers legitimate ecological aims such as the conservation of natural resources, reduction of carbon emissions, protection of worker health, and the restoration and/or preservation of habitat."
Similar to how one household that merely recycles aluminum cans might still consider itself green versus another household that utilizes geothermal power, the threshold defining green burial is ultimately up to you and how much you wish to minimize your carbon footprint and/or help the environment.
Traditional Burial vs. Green Burial
In general, a traditional funeral followed by ground burial involves the use of a formaldehyde-based embalming fluid, as well as the obvious need for land use when burying a casket or coffin.
Moreover, according to the Greensprings Natural Cemetery Preserve in Newfield, New York, the annual ecological impact of a traditional ground interment in a United States cemetery includes, among other things, the burial of:
• 30-plus million board feet of hardwoods (much [of it] tropical; caskets)
• 1,636,000 tons of reinforced concrete (vaults)
• 827,060 gallons of embalming fluid
• 90,272 tons of steel (caskets)
These figures do not reflect the chemical fertilizers and pesticides that cemeteries use each year, or the emissions from grass-trimming and -cutting equipment, which also require the use of non-renewable fossil fuels.
In contrast, green burial favors the use of refrigeration, dry ice, a non-formaldehyde-based embalming fluid or some other "natural" method of preserving the body between the time of death and the funeral or memorial service. (Holding the service soon after the death (within 48 hours) also minimizes the need for preservation.) If a "container" (casket or coffin) is used, it should be crafted from a natural, biodegradable and, ideally, sustainable material. No metal fasteners, such as screws or nails, or metal hardware should be used.
And while burial of a body also requires land use, the use of an eco-friendly, natural and biodegradable material -- such as linen or wool for a shroud, or cardboard, wicker or other sustainable material for a casket or coffin -- encourages rapid decomposition and the return of the body's nutrients into the soil.
Finally, a green-burial setting is not maintained by a landscaping crew but instead appears as it would naturally. A traditional gravemarker or headstone is generally not allowed. Instead, some natural-burial cemeteries allow the use of a small, unpolished, flat stone to mark a gravesite. Survivors may choose to have the deceased's name and birth/death dates engraved upon it. Other green-burial cemeteries insist that only a tree (existing or planted at the time of death) may be used, or the location of the gravesite noted using GPS coordinates.
Cremation vs. Green Burial
Cremation, long considered an environmentally friendly or eco-conscious choice of bodily disposition versus traditional ground burial, does not qualify as "green" according to the NFDA or GBC. While cremation generally reduces land use, the cremation process itself can, potentially, generate airborne emissions that harm the atmosphere.
In addition, cremating a body requires non-renewable fossil fuels. According to the Greensprings Natural Cemetery Preserve, you could drive roughly "4,800 miles on the energy equivalent of the energy used to cremate someone -- and to the moon and back 83 times on the energy from all cremations in one year in the U.S."
Because cremated remains do not necessarily need to be interred in a cemetery, land use is reduced versus traditional burial (and scattering cremated remains obviously uses no land). Some might argue, however, that cremation precludes the natural decomposition of the body, preventing it from benefitting the natural ecosystem.
How Green is Your Valley?
If you seek to minimize your impact on the natural environment after you die, then your best choice is to research your options ahead of time in order to plan the burial that means the most to you. Fortunately, interest in green or natural burial is growing so the amount of information available is increasing. For example, the GBC offers a convenient planning guide to help you organize your thoughts and determine how you define a green burial. The Centre for Natural Burial offers listings of natural-burial preserves in Canada, the United States, and in the United Kingdom and Europe, as well as proposed sites.
Once you have envisioned what you want, you should share your plan with your family or loved ones. You can also discuss your wishes with a funeral director, cemetery counselor or other end-of-life planner.
