Flame, water or earth: which aftercare fits your priorities?
For human cremation, water cremation has about 1/10[1] the carbon footprint of flame, by one US estimate, and still returns ashes you can plant. Move the sliders to see how it ranks against the other options for you.
- Five options ranked by what you care about

Using the tool
Setting the sliders so the ranking means something
There are five sliders: keeping costs low, keeping your pet close, environmental impact, speed and simplicity, and room for a ceremony. Each runs from "doesn't matter" to "very important". Set them honestly rather than how you think you should feel; it's fine if cost matters more than carbon.
If you're planning a bio urn, the keeping them close slider matters more than it looks. Any tree, garden or water urn needs ashes returned, which rules out communal cremation. Our services page explains which urns suit which option. The ranked cards update instantly, each with a typical US cost, what it's good for and what to keep in mind.
Under the hood
How the tool scores and ranks each option
Every option has a score from 1 to 5 on each of the five priorities. We multiply each score by how much that priority matters to you, add them up, and show the result as a percentage of the highest possible total. The scores are our own judgement, based on the sources below, and they're shown openly so you can disagree with them.
| Option | Cost | Keeping close | Environment | Speed | Ceremony |
|---|---|---|---|---|---|
| Private flame cremation | 3 | 5 | 2 | 3 | 4 |
| Communal flame cremation | 5 | 1 | 3 | 5 | 1 |
| Water cremation | 3 | 5 | 5 | 3 | 3 |
| Home burial | 5 | 4 | 4 | 5 | 5 |
| Pet cemetery burial | 1 | 4 | 2 | 3 | 5 |
Costs come from published US figures for a typical dog, which the cards round to about $200 to $480 for private cremation and $650 to $1,550 for a cemetery plot. Private dog cremation averages about $260[2], pet cemetery burial about $831[3], and one insurer lists aquamation at $80 to $450[4]. A water cremation cycle takes 12–20 hours[5], which is why its speed score sits in the middle.
The carbon question
What the environmental numbers do and don't show
Water cremation scores highest on environment because every published comparison points the same way. A Dutch life-cycle study for TNO put a human flame cremation at 79.9 kg CO2e[6] and water cremation at -31.8 kg CO2e[7], the negative figure coming from credits for recovered metals and avoided products. A 2011 analysis cited by the Veterinary Sustainability Alliance found resomation of a human body had 33x / 85x less[8] environmental impact than cremation and burial respectively. For the limits of those studies, see our look at whether aquamation is really greener for pets.
79.9 kg CO2e[6]
A TNO life-cycle assessment estimated the global-warming impact of an average cremation at 79.9 kg CO2-equivalent per body.
-31.8 kg CO2e[7]
The same TNO assessment put resomation (alkaline hydrolysis) at -31.8 kg CO2e per body, a net negative figure driven by credits for recycled metals and avoided products.
~31 kg CO2e per animal[9]
Each shelter-animal flame cremation emits about 31 kg CO2e on average.
Here's the honest caveat: those studies were about human bodies. We found no equally detailed life-cycle study for pets. Pet cremators often run several animals in shared or partitioned cycles, and a cat has a tiny fraction of an adult's mass, so the absolute numbers shrink a lot. Our own rough estimate for a single animal flame cremation is shown above. The direction, water lower than flame, is well supported; the exact size of the saving for your pet is not. The closest pet figure we have is our own: by our estimate from US shelter data, an average animal flame cremation comes to ~31 kg CO2e per animal[9], and most of those animals were small and shared a cycle.
Worked example
A renter who wants a tree and a low footprint
Imagine someone whose 12-year-old cat has just died. They rent, want to plant a memorial in a large pot, and care a lot about the environment. They set environment to very important, keeping close to important, and leave cost, speed and ceremony on somewhat.
- Home burial comes out around 89%, because it scores well on cost, environment and ceremony.
- Water cremation follows at about 82%.
- Private flame cremation lands near 66%, with pet cemetery and communal cremation below that.
The top result isn't the answer here, and that's the point of reading the cards. A renter usually can't bury a body in the yard and couldn't take the grave with them. Water cremation returns ashes that can go into the pot, so it's the practical winner. Our guide on eco-friendly aftercare without greenwash walks through similar trade-offs.

The fine print
What the ranking leaves out
The tool doesn't know whether water cremation is offered near you, whether your land allows burial, or whether your cat's vet has a contract with one crematory. It uses US prices for a typical dog, so a cat will often cost less and a giant breed more. And it can't weigh the feeling of watching a tree grow against the practical sense of an urn on a shelf.
Use the ranking to start a conversation, then check availability locally. Our locations hub covers where pet water cremation is easier to find. The Cremation Association of North America tracks where water cremation is legal for people, and pet rules often differ again, so ask locally.
What next
Turning a ranking into a plan
If water cremation ranks high for you, ask local providers whether they offer it, whether the cycle is individual or shared, and what the returned remains look like. If flame cremation fits, you can still choose a planting or water urn afterwards. Either way, the urn size calculator tells you how much ash to plan for.

Questions people ask
Is water cremation really better for the environment than flame?
Every published comparison we've found says it uses much less energy and produces much less carbon. Most of that research was done on human funerals, so the exact saving for a pet is uncertain. The direction is well supported; treat any precise pet figure as an estimate.
Can I plant the ashes from water cremation?
Yes. Water cremation returns bone mineral, dried and reduced to a fine powder, much like flame cremation ash. It's still alkaline, so dilute it with plenty of compost and soil and give the mix time before planting, just as you would with flame cremation ashes.
Why is communal cremation ranked low for bio urns?
Because no ashes come back. Communal cremation can be a sensible, lower-cost choice, but if you want a tree, garden or water urn memorial, you need your pet's own ashes returned, which means private or individual cremation by flame or water.
Does water cremation cost more than flame cremation?
Often only a little, and sometimes not at all. One US insurer's guide puts pet aquamation at roughly $80 to $450[4] depending on size and whether the cycle is individual, overlapping the typical range for private flame cremation. Ask for a written total, including any pickup and urn.
Is home burial greener than any cremation?
It uses no fuel, which counts in its favour, but it depends on the site. A grave needs enough depth, distance from water and a permanent home. For renters or people likely to move, cremation followed by a planting or container memorial is usually the more workable green choice.
