Have you ever imagined yourself becoming a tree after you die, your remains nourishing the earth instead of polluting it? It's a beautiful thought, isn't it? But when we dig beneath the surface of the eco-funeral industry's promises, what do we really find?
Welcome to FreeAstroScience.com, where we're dedicated to unraveling complex scientific principles and presenting them in ways that make sense to real people living real lives. We're here because we believe in one fundamental principle: never turn off your mind. Keep it active. Question everything. Because, as the old saying goes, the sleep of reason breeds monsters.
Today, we're tackling something deeply personal yet universally relevant—death. Specifically, we're examining whether the green burial movement delivers on its environmental promises or if it's just sophisticated marketing wrapped in organic aesthetics. Stick with us through the end, because what we've uncovered might surprise you. You're not alone in wondering if there's a better way to leave this world. Let's find out together.

Why Are We Suddenly Worried About How We Die?
Death has terrified humans since we first became conscious of our own mortality. The 17th-century mathematician Blaise Pascal admitted he was "frightened" when considering the brevity of life. Throughout history, we've built elaborate burial practices, written countless stories about loss, and created entire cultures around how we handle death.
But something shifted in the past decade.
We discovered that death itself might be harming the planet. Every year, approximately 3.6 billion kilograms of human flesh and bone need disposal worldwide. That's staggering when you think about it. And here's the kicker: the methods we've relied on for generations—burial and cremation—carry significant environmental costs.
Consider this: a single cremation emits nitrogen oxides equivalent to driving a car almost 3,670 kilometers. That's like driving from New York to Los Angeles and then some.
Tony Walter, an emeritus professor of death studies at the University of Bath, describes this shift as "a (new) death mentalité"—a completely new shared attitude. We're no longer just grieving individual losses. We're grappling with species extinctions happening at unprecedented rates during our time on Earth.
Climate change has transformed how we think about everything, including our final act.
The Carbon Footprint of Forever
The numbers tell a sobering story. Traditional burials involve embalming chemicals, non-biodegradable caskets, concrete vaults, and manicured cemetery grounds requiring pesticides and water. Cremation burns fossil fuels at extreme temperatures. Both methods leave environmental scars.
This realization sparked a question that now haunts the funeral industry: if living sustainably matters, shouldn't dying sustainably matter too?
What Started the Green Death Movement?
The story begins in 1993 in Cumbria, England. Ken West, a bereavement services manager, heard requests from people who wanted burial among the wildflowers planted across 20 acres of cemetery land where he worked. He said yes.
That decision transformed Carlisle Cemetery into the first place offering commercial "woodland burial." No embalming. No chemical preservation. No concrete vaults or elaborate headstones. Just bodies returning to soil naturally, the way humans handled death for millennia before the modern funeral industry emerged.
Family members planted saplings—mostly oak trees—instead of erecting monuments. Each spring, snowdrops, daffodils, and bluebells bloomed beneath growing canopies. The dead nourished new life.
This wasn't revolutionary in historical terms. Islamic and Jewish traditions have long used biodegradable shrouds. Many ancient cultures simply dug shallow graves or left bodies exposed to natural elements. What made Carlisle Cemetery notable was its context: a Western funeral industry obsessed with preservation, with making bodies look "lifelike" indefinitely, suddenly offering an alternative that embraced decay.
The Philosophy Behind Natural Return
At the turn of the 21st century, green death practices multiplied. They offered more than technical solutions for disposing remains. They presented new ways of understanding what a dead human body could mean—its value, its potential contribution, its relationship to Earth.
Caitlin Doughty, a mortician from The Order of the Good Death, captured this shift in 2011: "If we work towards accepting, not denying, our decomposition, we can begin to see it as something beautiful. More than beautiful—ecstatic."
Thousands of providers worldwide now offer green burial options. The movement expanded from simple woodland burials to include technologies our ancestors never imagined.
What Green Death Options Actually Exist Today?
Let's walk through what's actually available—and what's just clever marketing.
Woodland Burials
These continue the tradition Ken West started. Bodies go into the ground without embalming, in biodegradable coffins or simple shrouds. Trees mark graves instead of headstones. Over time, the body decomposes naturally, nutrients seeping into surrounding soil.
This option exists. It works. It's available in numerous locations across the UK, US, Australia, and other countries.
Alkaline Hydrolysis
Also called resomation, aquamation, or water cremation, this process dissolves the body using an alkali-based solution heated to around 160 degrees Celsius. It reduces remains to basic components. Bones get crushed into ash. The residual fluid enters wastewater treatment systems.
Developed in the 1990s, this method attracted Archbishop Desmond Tutu, who chose it for his burial in 2021. Companies market it as the most environmentally friendly option available. It uses significantly less energy than fire cremation.
But here's something to consider: it originated as a method for disposing farm animals. That doesn't make it wrong—just worth knowing.
Natural Organic Reduction (Human Composting)
This is where things get interesting. Natural organic reduction—marketed as "terramation" or "recomposition"—places bodies in vessels between layers of woodchips, straw, and alfalfa. Microbes decompose the body over several weeks or months, producing humus (the organic matter in soil). The remains are then "cured" in open air for additional weeks.
Recompose, a Seattle-based company, opened the first facility using this method in 2020. Founder Katrina Spade led the charge to legalize human composting in the US. The company's messaging is powerful: "Healthy soil is vital for an ecosystem to thrive. It regulates moisture, sequesters carbon, and sustains plants, animals, and humans."
They call their process "Life After Death."
Tree Burials
Several companies offer variations on becoming a tree posthumously. Mornington Green in Australia operates a memorial garden on land reclaimed from a golf course near Melbourne. They inter cremated remains under established saplings.
What sets them apart? They match personality to tree species. Take their two-minute quiz and discover whether you're a "tenacious and hopeful" ginkgo, a "unique and strong" trident maple, or a "charismatic and passionate" flame tree.
It's undeniably appealing. Who wouldn't want their essence captured in the qualities of a living organism?
Capsula Mundi
Perhaps the most romantic vision: an egg-shaped biodegradable pod houses a corpse curled in fetal position underground, feeding nutrients to a tree above. The symbolism is profound—death and life intertwined, continuous cycles of rebirth.
The website promises: "Life is forever."
There's just one problem: it doesn't exist yet. Not for whole-body burial. Despite widespread media coverage suggesting otherwise, Capsula Mundi has never successfully been used this way. Similar devices are sold as urns for cremated remains, but the full vision remains unrealized.
Cryomation
This involves freezing bodies in liquid nitrogen at -196 degrees Celsius, shattering them into fragments, freeze-drying the pieces, and burying them in biodegradable containers that decompose over 12 months.
Originally called "promession," a Swedish company proposed it but never reached human trials. UK-based Cryomation received significant funding from the European Commission, Innovate UK, and Shell. They've never launched a commercial prototype.
So it's vapor—or rather, frozen vapor that never materialized.
Why Do These Eco-Burials Appeal to Us?
Beyond environmental concerns, green death technologies offer something deeper: meaning without religion.
Think about it. If you don't believe in heaven or reincarnation, what happens when you die? The scientific answer—you decompose, your molecules scatter—can feel cold and empty. Green burials transform that stark reality into something comforting.
As astronomer Carl Sagan reflected: "The cosmos is also within us. We're made of star-stuff. We are a way for the cosmos to know itself."
Secular Eschatology
Anthropologist Douglas Davies calls this thinking "secular eschatology" in his book "A Brief History of Death" (2005). Religious studies scholars describe it as "dark green religion," "reverential naturalism," or "relational naturalism."
You don't need God to find profound meaning in death. Secular funeral services at green burials might include Aaron Freeman's "Eulogy from a Physicist," which ends: "According to the law of the conservation of energy, not a bit of you is gone; you're just less orderly. Amen."
Recompose offers their own "carbon cycle" funeral service. Staff remind mourners that molecules of the deceased will be "transformed and incorporated back into life."
It's poetry grounded in chemistry. Spirituality rooted in ecology.
Absolution for Climate Guilt
Here's where things get complicated.
Some companies frame green death as redemption for a lifetime of carbon emissions. Transcend, a US tree-burial company, claims their natural burial method achieves "100 per cent reversal of your lifetime carbon footprint (based on global averages)."
Read that again. They're suggesting that choosing their burial completely erases your environmental impact.
That's a bold claim. An appealing claim. And possibly a misleading claim.
Do Green Funerals Really Work as Advertised?
Let's examine the evidence—or lack thereof.
The Marketing vs. The Science
Companies promoting green death technologies make sweeping environmental claims. Transcend says their tree burials are "576 per cent more sustainable than cremation." An Australian alkaline hydrolysis provider claims their service "uses less than 10 per cent of the energy of a traditional fire cremation." Cryomation boasts "a 70 per cent lower carbon footprint than Cremation."
Recompose states: "For every person who chooses Recompose over conventional burial or cremation, one metric ton of carbon pollution is prevented. In addition, our approach to human composting uses 87 per cent less energy than conventional burial or cremation."
These numbers sound impressive. But there's a problem: companies don't show their calculations. It's unclear how they measure environmental impact. Some reference pilot studies or internal trials, but they haven't released raw data or detailed analyses.
No independent authority verifies these claims. No regulatory body prevents companies from making them.
For journalists, academics, and especially grieving families trying to make informed decisions, this opacity creates real problems.
What Does Independent Research Actually Say?
Very few peer-reviewed, independent studies assess or compare burial technologies' overall environmental impact.
The Netherlands Organisation for Applied Scientific Research published two reports in 2011 and 2014. They conducted life-cycle assessments of different burial options and ranked them by environmental impact:
But these reports are now over a decade old. They don't include human composting methods. They're specific to the Netherlands and not easily applicable elsewhere.
A 2023 report from UK sustainability company Planet Mark took another look. Again, alkaline hydrolysis ranked as most sustainable. But the authors made questionable assumptions—like suggesting graves in natural burials are dug manually rather than by machine, which rarely happens in practice.
The Complexity of "Green"
Declaring one method "greenest" gets complicated fast. A technique might excel in carbon emissions but consume excessive water. It might work well in one location but poorly elsewhere.
Hidden environmental impacts lurk throughout supply chains. What about emissions from growing the alfalfa and straw used in human composting? What about transporting bodies long distances to access alkaline hydrolysis facilities that might be hundreds or thousands of kilometers away?
Here's something most green burial advocates won't emphasize: body decomposition itself represents only a tiny fraction of death's total environmental impact.
What about the catering at the funeral? The flowers imported from another continent? The marble headstone quarried overseas? The dozens of visitors driving or flying from distant locations?
As the Planet Mark report concluded: "recurrent visits to the final resting place has a much higher impact over the years than any of the disposal methods."
Think about that. Years of family members driving to visit a grave might outweigh the emissions saved by choosing composting over cremation.
The Real Comparison
Here's the most sobering truth: everything we do in death pales compared to our lives' environmental impact.
The 2011 Dutch report stated it plainly: "the relative value of the environmental impact of funerals, however, scores low in all effect categories compared with the resource use and emissions of one year of life of an individual."
One year of living generates far more environmental harm than your entire burial, no matter which method you choose.
What Should We Actually Do About Death and the Environment?
We're not saying green burials are bad. They offer meaningful narratives that help people make sense of mortality. Visions of death as peaceful, regenerative, and beautiful provide comfort.
The danger lies in inflated environmental credentials and clever greenwashing.
The Distraction of Individual Choice
Focusing on personal decisions—should I become a tree, compost, or liquid?—represents a market solution that distracts from collective action.
The real task falls to government regulators and the funeral industry, not grieving families.
Effective changes often look unromantic. Simply improving existing facilities can sometimes work better than pursuing new technologies. This includes:
- Installing nitrogen oxide and mercury abatement equipment in crematoria
- Restricting international importation of granite for headstones
- Increasing recycled materials in concrete
- Converting vehicles and crematoria from gas to electricity
These approaches balance environmental concerns against other sector-wide challenges, including protecting deathcare workers who face stigmatization, low pay, and significant occupational health hazards.
But none of these options carry the same appeal as becoming a tree. They don't promise personal transformation or ecological redemption. They're bureaucratic, technical, unglamorous.
The Accessibility Problem
Green death technologies aren't equally available. Human composting is legal in only a handful of US states. Alkaline hydrolysis is commercially available in select locations across the UK, Australia, South Africa, Canada, and Ireland.
Natural burial grounds can be scarce. If you need to transport a body thousands of kilometers to access green burial options, you've potentially negated any environmental benefit.
There's something darkly ironic about needing to burn fossil fuels transporting corpses long distances so they can have "green" burials.
What Does Real Change Look Like?
A genuine ecological approach to death wouldn't place responsibility solely on dying individuals or grieving families. It would require rethinking deathcare infrastructure itself:
- Energy systems powering crematoria
- Materials used in funerary goods
- Regulations governing emissions and land use
- Labor conditions for deathcare workers
Only when our stories of renewal match transparent evidence and systemic change will green death become more than consoling fiction.
Should You Still Choose Green Burial?
Here at FreeAstroScience, we're not telling you what to do. We're giving you information so you can decide for yourself.
If green burial provides comfort and meaning during an impossibly difficult time, that matters. The narrative value of returning to nature shouldn't be dismissed. Finding peace in imagining yourself nourishing a tree or enriching soil isn't foolish—it's deeply human.
Just go in with eyes open. Understand that environmental claims might be exaggerated. Recognize that accessibility varies wildly depending on where you live. Know that your life's impact dwarfs your death's impact.
And maybe, just maybe, channel some of that concern for your posthumous footprint into how you live right now. That's where the real difference lies.
We wrote this piece specifically for you because at FreeAstroScience.com, we believe in presenting complex scientific and social issues in terms that make sense. We're not here to tell you what to think. We're here to give you the tools to think critically for yourself.
The green burial industry has created beautiful visions of death transformed into renewal. Some of those visions deliver on their promises. Others are more aspiration than reality. Distinguishing between the two requires the kind of engaged, critical thinking we champion here.
Remember: never turn off your mind. Stay curious. Question claims, even appealing ones. Especially appealing ones. Because the sleep of reason breeds monsters—or in this case, greenwashing that preys on our deepest anxieties about mortality and meaning.
Death remains a mystery we'll each face alone. But understanding the options available to us, seeing clearly through marketing haze to scientific reality, connects us to something larger than ourselves. Not through magical thinking about becoming trees, but through honest reckoning with our place in natural systems—both in life and in death.
