Understanding Cremation: A Brief Background
Cremation is the process of reducing a deceased body to ash using high heat and flame. Modern crematories heat bodies to temperatures between 1400 and 1800 degrees Fahrenheit, effectively vaporising the body, leaving behind bone fragments or 'ashes'.
The Environmental Cost of Cremation
One of the primary pollutants associated with the cremation process is mercury, mainly emanating from dental fillings. According to the Cremation Association of North America, a typical cremation releases about 0.8 grams of mercury into the atmosphere.
Carbon Dioxide Emissions
Cremation also contributes to greenhouse gases through the release of carbon dioxide (CO2). It's estimated that a single cremation produces about 160kg, approximately equal to the CO2 emissions from a 500-mile car trip.

To reach the high temperatures necessary for cremation, traditional crematories burn non-renewable fossil fuels like natural gas or propane. This energy consumption adds to the environmental impact of cremation.
Are There Environmentally-Friendly Alternatives?
Yes, there are increasingly innovative, environmentally-conscious alternatives available today, including water cremation and green burials.
Water Cremation (Alkaline Hydrolysis)
This method uses water and an alkali solution to chemically break down the body, significantly reducing the carbon footprint compared to traditional cremation.
Green Burial
This practice returns the body to the earth in the most natural way possible, using biodegradable caskets, no embalming fluids and preserving natural habitats as green cemeteries.
Is Cremation Bad for the Environment Example:
An example of the growing eco-concern in the funeral industry is the recent popularity of bio-cremation, also known as water cremation or alkaline hydrolysis. The process uses 90% less energy than conventional cremation, emits less CO2 and completely eliminates mercury emissions. Additionally, the process results in 20% more ashes returned to the family, which can serve as a comfort during their grieving process.
Frequently Asked Questions
What are the environmental impacts of cremation?
Cremation has several environmental impacts, including the release of greenhouse gases, mercury emissions from dental amalgams, and the consumption of natural gas or other fuels. It's estimated that a single cremation uses as much energy as a 500-mile car trip and releases about 400 kg of carbon dioxide into the atmosphere.
How does cremation compare to burial in terms of environmental friendliness?
While cremation is generally seen as more environmentally friendly than traditional burial, which involves embalming fluids and non-biodegradable caskets, it still has significant environmental consequences. Green burials, on the other hand, which avoid embalming chemicals and use biodegradable materials, are considered more eco-friendly.
Can cremation contribute to climate change?
Yes, cremation contributes to climate change by releasing carbon dioxide, a greenhouse gas that contributes to the warming of our planet. Though the individual impact is relatively small, it adds up with the increasing rate of cremations globally.
Are there any ways to make cremation more environmentally friendly?
Crematoriums can take steps to reduce their environmental impact by using more efficient cremation technology, filtering emissions, and even using bio-cremation techniques, which use water and alkali instead of flame.
What is bio-cremation and is it better for the environment?
Bio-cremation, also known as alkaline hydrolysis, uses a solution of water and potassium hydroxide to break down the body. This method is considered more environmentally friendly because it uses less energy and produces fewer emissions than traditional cremation.
Does the cremation process release mercury into the environment?
Yes, cremations can release mercury into the environment through the vaporization of dental amalgam fillings during the process. This is a concern because mercury is a toxic substance that can accumulate in the food chain.
How much energy does a typical cremation use?
A typical cremation requires a substantial amount of energy, roughly equivalent to the amount needed to drive a car for about 500 miles. Modern cremation techniques are seeking to reduce this energy consumption.
What are the regulations around crematorium emissions?
Regulations regarding crematorium emissions vary by country and region, but they generally focus on controlling the release of pollutants, including particulates, carbon dioxide, and mercury, through the use of filters and scrubbers.
Can I offset the carbon footprint of a cremation?
Yes, one can offset the carbon footprint of a cremation by investing in carbon offset projects such as reforestation or renewable energy initiatives, which aim to balance out the emissions produced.
Is it true that cremation requires fewer resources than a traditional burial?
In general, cremation requires fewer physical resources than a traditional burial since it eliminates the need for a casket, burial vault, and extensive land use for gravesites. However, it still consumes a significant amount of energy.
Are cremation ashes harmful to the environment if scattered?
Cremation ashes are mostly composed of calcium phosphates and are considered to be benign. However, scattering them in sensitive ecosystems or large quantities can potentially harm the local environment. It's important to follow local regulations when scattering ashes.
What alternatives to cremation and traditional burial are gaining popularity?
Green burials, which emphasize minimal environmental impact, are gaining popularity as an alternative. Other alternatives include bio-cremation, natural organic reduction (human composting), and sea burials.
How does a sea burial compare environmentally to cremation?
Sea burials can be more environmentally friendly than cremation if conducted properly, as they do not emit greenhouse gases and promote marine life growth on decomposable materials. However, they must be legally and ethically managed to avoid environmental harm.
What kind of filters are used in crematoriums to reduce emissions?
Crematoriums may use various filters, such as bag filters, electrostatic precipitators, and after-burners, to reduce particulate matter and other emissions released during the cremation process.
Does the cremation process use water?
Traditional flame-based cremation does not use water, but bio-cremation uses a solution of water and potassium hydroxide to dissolve the body.
Can I have an eco-friendly cremation?
Yes, by opting for a crematorium that utilizes energy-efficient technology, filtering systems, and by considering alternative processes such as bio-cremation, one can aim for a more eco-friendly cremation.
What is a cremation casket and does it impact the environment?
A cremation casket is a specially designed casket intended for use during the cremation process. While traditional caskets can be constructed of various materials, cremation caskets are typically made from lighter, more combustible materials, and they may have lower environmental impacts if constructed from sustainable materials.
How can I ensure that my final wishes are environmentally friendly?
One can ensure environmentally friendly final wishes by planning for a green burial or eco-friendly cremation, using biodegradable materials, and considering options like tree planting or coral reef contributions in lieu of a traditional monument.
Is tree or coral reef burial more ecological than cremation?
Tree and coral reef burials, where biodegradable urns are placed in natural settings to support growth, can be more ecologically sustainable than traditional cremation, as they contribute to ecosystems rather than emitting greenhouse gases.
What are the pros and cons of human composting as compared to cremation?
Human composting, or natural organic reduction, is a process that transforms human remains into soil. Pros include lower carbon emissions and the creation of useful compost. Cons may include cultural acceptance and regulatory limitations. It compares to cremation by offering a more sustainable and resource-efficient option but is not yet widely available.
How do cultural and religious beliefs impact the choice between cremation and greener alternatives?
Cultural and religious beliefs play a significant role in end-of-life decisions. Some traditions may have preferences or prohibitions regarding cremation or burials. Open discussions and education about greener alternatives are important for aligning environmental considerations with personal beliefs.
In conclusion, while traditional cremation does have environmental impacts, innovations within the funeral sector offer growing alternatives that can align with your eco-principles.
