The Environmental Cost of Traditional Burial

What goes into the ground

A conventional American burial typically involves several material-intensive components: an embalmed body, a finished casket (commonly wood, steel, or occasionally bronze), and a concrete or metal burial vault or grave liner surrounding the casket. Each of these elements — a practice that became the default over the course of the 20th century — carries its own material and environmental cost, most of which simply isn't necessary from a purely biological standpoint.

Land use

Cemetery land is permanently dedicated to a single use and, once filled, is rarely returned to other purposes. In densely populated regions and major cities, this has become a genuine planning concern — several cities worldwide have faced or are approaching a shortage of available cemetery space, a pressure that has directly accelerated interest in cremation, vertical columbaria, and land-efficient alternatives like conservation burial and memorial forests, which are covered in more detail on our Burial Methods page.

Embalming chemicals

Embalming fluid is commonly formaldehyde-based, along with other preservative and disinfectant compounds. Over time, and across the scale of an entire cemetery, this introduces a cumulative volume of chemical preservatives into the soil that green burial and several emerging methods are specifically designed to avoid. It's worth noting that no U.S. state legally requires embalming for a standard, prompt burial — its widespread use largely reflects funeral industry convention around extended viewings rather than any legal mandate.

How it compares to alternatives

Green burial eliminates embalming chemicals, vaults, and non-biodegradable caskets, directly reducing the largest material inputs of conventional burial. Cremation avoids land use and vault materials but consumes significant fossil-fuel energy and releases combustion byproducts. Natural organic reduction and alkaline hydrolysis, as emerging methods, are generally reported by providers and independent researchers to have a smaller combined footprint than either conventional burial or flame cremation, since they avoid both chemical preservation and high-temperature combustion. We cover each of these methods, along with their specific environmental tradeoffs, in dedicated guides linked throughout this site.

What's changing

Consumer demand for lower-impact options has grown steadily, and the funeral industry has responded: certified green burial cemeteries and hybrid sections have expanded significantly across North America, the UK, and parts of Europe and Australia over the past two decades, and newer methods like natural organic reduction have moved from research concept to state-legalized practice in less than a decade. This doesn't mean traditional burial is disappearing — many families still prefer its familiarity and established rituals — but it does mean the range of genuinely available lower-impact choices has expanded substantially.
