A Growing Concern for Families
As cremation becomes increasingly common in British Columbia and across Canada, more families are asking whether it is environmentally friendly.
In cities such as Vancouver, Burnaby, and Richmond—where green living is a community value—this question carries even greater weight. While cremation is often considered less resource-intensive than traditional burial, the environmental impact is more complex than it may first appear.
Comparing Cremation and Burial
From an environmental standpoint, both cremation and burial have pros and cons:
- Cremation:
- Requires significant energy to reach high temperatures.
- Releases emissions such as carbon dioxide and trace metals into the atmosphere.
- Does not require land use in perpetuity.
- Burial:
- Uses land for cemeteries, which can be limited in urban areas like Vancouver.
- Involves embalming chemicals, which may enter soil and groundwater.
- Requires ongoing maintenance of gravesites, often with fertilizer or pesticides.
Families weighing these options often find cremation to be more environmentally practical, though neither is entirely impact-free.
Advances in Cremation Technology
Crematoriums in Canada, including those in the Lower Mainland, are adapting new methods to reduce impact:
- Efficient retorts: Modern chambers use less fuel while maintaining proper temperatures.
- Secondary combustion systems: These capture and re-burn gases to lower emissions.
- Filtration systems: Some facilities use filters to trap particles before they are released.
These innovations help make cremation more eco-conscious compared to older systems.
Alternative Eco-Friendly Options
For families particularly concerned with the environment, there are additional choices:
- Biodegradable urns: Designed to return safely to the earth or ocean.
- Aquamation (alkaline hydrolysis): An emerging method that uses water and alkali instead of flame, significantly reducing carbon output. Availability in BC is still limited but growing.
- Tree planting memorials: Families may choose to combine ashes with soil to nourish a tree, creating a living tribute.
Community and Cultural Considerations
In Vancouver, where diverse cultures live side by side, families often balance environmental concerns with tradition. Some may prefer scattering ashes in meaningful outdoor locations, while others focus on green burial grounds. British Columbia’s landscape offers many options for eco-conscious memorialization.
Limitations of Cremation’s Green Image
While cremation avoids some of the land-use issues associated with burial, it does release greenhouse gases. One cremation can produce roughly the same carbon output as a cross-country car trip. This reality can surprise families who initially believe cremation is a purely eco-friendly choice.
Making an Informed Decision
Families concerned about the environment can ask local providers in the Lower Mainland about:
- The type of equipment used at their crematorium.
- Availability of biodegradable urns.
- Alternative methods such as aquamation.
- Opportunities for offsetting emissions through tree planting or charitable contributions.
A Balanced Perspective
Cremation is not entirely without environmental impact, but it is often chosen because it aligns with both practical needs and evolving ecological awareness.
In British Columbia, where sustainability is a shared value, families increasingly seek ways to minimize their footprint while honoring loved ones.
By learning about the environmental aspects of cremation, families can make thoughtful choices—whether by selecting eco-friendly urns, exploring alternatives like aquamation, or combining traditional practices with sustainable actions.
