Environmental Footprint
Understanding Green Funeral Environmental Impact
The green funeral environmental impact of an end-of-life choice comes down to three things: the carbon emitted, the land used, and the manufactured materials consumed. This free calculator compares four common US options — traditional burial, flame cremation, green (natural) burial, and aquamation — using approximate per-body estimates so you can weigh the trade-offs before you decide.
The differences are real. A traditional burial combines embalming chemicals, a hardwood casket, and a concrete vault with permanently maintained cemetery land — the most resource-intensive path. Flame cremation avoids the casket and vault but burns natural gas at high heat, so its carbon footprint is nearly as high as burial even though it uses almost no land. Green burial skips the embalming, vault, and metal casket and lets the body return to the soil, while aquamation (alkaline hydrolysis) uses water and an alkali solution instead of fire, producing the lowest estimated emissions of the four.
Cost and carbon do not always move together, which is why this tool shows both. A lower-impact choice is frequently also the less expensive one, but availability matters: green burial requires a natural or conservation cemetery near you, and aquamation is only offered in some states. Use the figures here as a planning starting point, then confirm prices and options with local providers.

How it works
How to Use This Calculator
Pick one disposition type and select Calculate Impact. The results panel appears below the buttons and reports three numbers for your choice: estimated CO2 emissions in kilograms, land use in square meters, and a typical US cost range. It also shows how that option compares with a traditional burial — the most resource-intensive baseline — so you can see the carbon you would save or add.
Run each of the four options in turn to build a side-by-side picture. Pair the carbon figure with the land-use figure rather than reading either alone: cremation, for example, scores well on land but poorly on carbon. The benchmark table further down lists every option together if you prefer to compare at a glance.

Environmental Impact at a Glance
Approximate per-body estimates for the four main US options, with typical cost ranges. Lower CO2 and land-use values mean a smaller footprint; figures vary by facility and region.
| Option | CO2 (est.) | Land Use | Typical US Cost |
|---|---|---|---|
| Traditional Burial | 250 kg | 2.5 m² | $7,000 – $15,000 |
| Standard Cremation | 245 kg | 0.1 m² | $4,000 – $9,000 |
| Green/Natural Burial | 50 kg | 1.5 m² | $3,000 – $8,000 |
| Aquamation | 35 kg | 0 m² | $4,800 – $13,500 |
* CO2 and land-use values are approximate estimates. Costs are US national-average ranges; aquamation pricing is estimated relative to cremation and varies by state availability.
Questions answered
Frequently Asked Questions
A green or natural funeral minimizes environmental impact through: no embalming (or using eco-friendly fluids), biodegradable caskets or shrouds, natural burial grounds without concrete vaults, and conservation-focused cemeteries. The goal is to allow the body to return to the earth naturally.
Green funerals often cost less than traditional funerals: $3,000-$8,000 vs $7,000-$15,000+. Savings come from: no embalming, simpler biodegradable caskets, and natural burial plots (often cheaper than traditional cemeteries). However, green cemeteries may be limited in some areas.
Aquamation uses water and alkali to break down the body, producing about 90% less carbon emissions than cremation. The process takes 6-20 hours and results in bone fragments (like cremation) and sterile liquid. It's legal in about 20 US states and growing.
Conservation cemeteries are natural burial grounds that also serve as nature preserves. They use grave fees to acquire and protect land. Bodies are buried without vaults, in biodegradable containers, with native plant markers instead of headstones.
No, embalming is rarely required by law. It may be required only for: shipping remains across state lines, long delays between death and burial, or certain public viewings. Refrigeration is an alternative. Ask your funeral home about non-embalming options.
Options include: wicker/willow caskets, bamboo caskets, cardboard caskets, pine or softwood caskets, wool caskets/coffins, and simple burial shrouds. Costs range from $100 (shroud) to $2,000 (wicker). All decompose naturally in the ground.
Green burial is legal in all 50 states. No federal or state law requires embalming, a metal casket, or a concrete vault for a standard burial. Some conventional cemeteries do require an outer burial container as a private policy, so green burial is easiest at a dedicated natural or conservation burial ground. The Green Burial Council certifies cemeteries, funeral homes, and products that meet its standards.
By the estimates in this tool, no. Standard flame cremation produces roughly 245 kg of CO2 per body — close to a traditional burial's 250 kg — because it burns natural gas at high heat. Green burial is estimated at about 50 kg and aquamation at about 35 kg. Cremation does use the least land, so the right choice depends on which impact (carbon versus land) matters most to you. These figures are approximate estimates that vary by facility and equipment.

Data sources & methodology
Environmental figures (CO2 emissions, land use, resources) are approximate per-body estimates drawn from green-burial and cremation industry sources, and vary by facility, equipment, and region. Cost ranges are US national averages; actual prices and the availability of green burial or aquamation differ by provider and state. Verify legality and pricing with local providers.
