Approximately 170,000 people die every day around the world—that's around 62 million deaths . The cumulative effect of this has led to what has been termed a "burial crisis," with most urban areas where burial remains the norm expected to run out of interment space by the 2050s, some much earlier—as in, now.

Major cities, including London and anticipate severe space shortages within the next decade. Smaller community cemeteries, such as Nuneaton cemetery in have already reached full capacity and begun directing families elsewhere. Finding culturally acceptable yet ethically responsible, accessible and sustainable ways of laying to rest, mourning and honoring our loved ones has become an urgent global issue.
However, the cemetery sector has only recently begun to seriously consider the environmental consequences of how we handle our bodies after death. The sense of urgency coincides with a significant cultural shift, as cremation increasingly replaces traditional burial methods. This is due to societal secularization, shifts in religious doctrines (including Catholicism lifting past bans) and its affordability .

In the UK, the percentage of cremations has risen from 9% of total burials in 1946 to 80.64% .

Yet, cremation is far from a sustainable alternative to burial. It releases substantial amounts of pollutants, notably carbon dioxide and mercury emissions, so . Technologically advanced techniques, such as —a process that uses an alkali-water-based solution to reduce a body to bones—have only recently begun to emerge as possible alternatives and remain niche.

For several years, we have been studying cemeteries in Italy and the UK. Despite the deeply different burial traditions in these two countries (unlike the UK, Italy remains a burial culture) both face the same environmental challenges.

A tale of two cemeteries

A few sites do offer environmentally conscious alternatives to traditional burial. One is in Liguria, a densely populated region in northwestern Italy that has suffered significant losses due to climate change, particularly from soil erosion caused by decades of reckless coastal construction.

Here, a group of environmentally conscious volunteers transformed a woodland called (the name means living woods) into a cemetery, creating Italy's first forest cemetery. Though it involves cremation, this initiative is particularly groundbreaking in a country where cemeteries have historically been conceived as monumental or architectural structures.

Often, they are heavily reliant on marble, a traditional hallmark of Italian craftsmanship, significantly reducing green spaces in urban areas. The also creates huge greenhouse gas emissions and .

In contrast, the cimitero bosco (forest cemetery) of Boschi Vivi follows a different philosophy. Instead of traditional tombstones, only a small plaque is placed near each tree where ashes have been scattered, marking the final resting place of the deceased.

Currently, this remains a grassroots initiative that's starting to emerge in too. Hopefully, more Italian public administrations will adopt this model as traditional cemeteries become increasingly financially and environmentally unsustainable.

For three decades, Oakfield burial ground in Wrabness, Essex, UK has adopted a similar approach. Oakfield wood is a seven-acre natural woodland burial site along the banks of the river Stour in north Essex, managed by the Essex Wildlife Trust. Instead of headstones or conventional memorials, a native broadleaf tree is planted for each burial, accompanied by a simple wooden plaque at its base. The site forms part of a larger nature reserve, fostering a rich habitat for wildlife.

Unlike municipal cemeteries or other burial sites, which are often subject to redevelopment or reuse, Oakfield enjoys long-term protection under the Essex Wildlife Trust. This means that burials here are conducted in perpetuity, ensuring that the site remains undisturbed. The trust plans to manage Oakfield solely as a nature reserve once it reaches full capacity, although this will not be for many decades to come.

Despite these promising initiatives, sites such as Boschi Vivi and Oakfield risk remaining isolated cases unless a radical rethinking of burial takes place. Whether cemeteries are perceived as eerie, macabre spaces (like in Shakespeare's Hamlet) or as places of peace and reconciliation, as in the final scene of Forrest Gump, they are still dominated by the idea that graves should be organized as a series of permanent markers of individual lives.

Our research shows that it's only by considering human beings as part of nature that the growing burial crisis might be averted. That fundamentally involves moving from a human-centered or "ego-logical" ethos to an ecological one.

The most viable response to the environmental challenges facing not just Nuneaton cemetery, but burial sites across the world, might simply be new awareness. One that recognizes both life and death as integral parts of nature. So, remembrance is not preserved through permanence, but rather through a return to the natural cycle of life.
