Green Burial Council Certified Cemeteries: What the Three Tiers Mean

What the Green Burial Council Certifies

The Green Burial Council (GBC) is an independent certification body for environmentally responsible burial practices in North America. When a cemetery carries GBC certification, it means a third party has verified that the facility meets specific environmental standards — it's not just a marketing label the cemetery gave itself.

GBC certification operates on three tiers, each with progressively stricter requirements. The tier tells you exactly what you're getting.

Tier 1: Hybrid Cemeteries

A hybrid cemetery is a conventional cemetery that has designated a section for green burials. The rest of the grounds may operate under standard practices — embalming, concrete vaults, traditional caskets — but the green section follows GBC rules.

Requirements for the green section:

• No concrete or metal vaults or grave liners
• Only biodegradable containers — shrouds, wicker, bamboo, untreated softwood, or cardboard
• No toxic embalming chemicals (formaldehyde-based fluids are prohibited; non-toxic, plant-based alternatives are permitted)
• The cemetery must accept any eco-friendly, biodegradable burial container that meets GBC standards

Hybrid certification is the most common because it's the easiest for existing cemeteries to implement. They don't need to change their entire operation — just carve out a section and enforce stricter rules within it.

Pricing for hybrid green burial plots typically runs $2,000 to $4,000, including opening and closing of the grave. That's often comparable to or slightly below conventional burial in the same cemetery, because you're not paying for a vault ($300–$1,500 savings) or an expensive casket.

Tier 2: Natural Burial Grounds

Natural burial grounds are dedicated entirely to green burial. There is no conventional section. Every interment follows GBC environmental standards across the entire property.

Additional requirements beyond hybrid:

• No non-native stone markers or monuments — only flat native stones, plantings, or GPS coordinates mark the graves
• Burial density capped at an average of 500 burials per acre (conventional cemeteries pack in 1,000+)
• An Ecological Impact Assessment is required before the cemetery can be certified
• Sustainable land-management practices must be in active use (native plantings, stormwater management, habitat restoration)

Natural burial grounds look and feel different from conventional cemeteries. There are no rows of headstones. The landscape is maintained as a meadow, woodland, or prairie. The visual effect is closer to a nature preserve than a graveyard.

Plot costs range from $1,500 to $5,000 depending on location. Some natural burial grounds include perpetual care in the plot price; others charge a separate maintenance fee.

Tier 3: Conservation Burial Grounds

Conservation burial grounds are the highest GBC certification tier. They function as nature preserves where burial fees directly fund land conservation.

Requirements beyond natural burial:

• The property operates in legal partnership with a recognized land trust or government conservation agency
• A legally binding conservation easement protects the land in perpetuity — it can never be developed, rezoned, or converted to another use
• Burial density is capped at 300 per acre (even lower than natural burial grounds)
• A portion of every burial fee goes directly to funding land restoration, wildlife habitat, and ecological monitoring

Conservation cemeteries accomplish something no other burial option does: every person buried there permanently protects additional acreage. The land trust model ensures the property survives even if the operating organization dissolves.

Plot costs range from $2,500 to $6,000. The premium over natural burial reflects the conservation easement and the ongoing restoration work funded by burial fees.

How to Find a Certified Cemetery

The GBC maintains a searchable provider directory on its website, filterable by state and certification tier. Use it to check current certified cemeteries near you.

Coverage is still thin in many areas. If there's no certified cemetery within a reasonable distance, you have a few alternatives:

Ask local conventional cemeteries about green burial sections. Some cemeteries allow green burials (no vault, biodegradable container) without being GBC-certified. The burial practices may be identical — they just haven't gone through the certification process.

Ask about private-land burial. Whether burial is allowed on a particular property depends on applicable state and local rules; check with local zoning and health authorities before making plans.

Look at alkaline hydrolysis or natural organic reduction as alternative low-impact disposition methods that don't require a cemetery at all.

What to Bring: Containers and Shrouds

All GBC-certified cemeteries accept:

• Natural fiber shrouds (cotton, wool, linen, silk)
• Wicker, bamboo, or seagrass caskets
• Untreated pine, poplar, or other softwood caskets
• Cardboard or fiberboard caskets

They do not accept: metal caskets, caskets with metal hardware, polyester-lined interiors, or anything with toxic finishes or sealants. If you're buying a casket for a green burial, confirm the materials before purchasing — some "eco-friendly" marketed caskets still contain small amounts of prohibited materials.

Shroud burial is the simplest and lowest-cost option ($100–$400 for the shroud). The body is wrapped in fabric, placed on a lowering board, and committed directly to the earth. Some families find this the most intimate and meaningful form of farewell.

Connecting Green Burial to Your Broader Decision

Green burial is one of several disposition methods that prioritize environmental values. The Choosing Between Burial, Cremation & Alternatives toolkit maps all the options — traditional burial, green burial, cremation, alkaline hydrolysis, and natural organic reduction — against cost, availability, religious compatibility, and environmental impact, so you can see where green burial fits relative to everything else.
