Real or Fake? The Environmental Impact of Christmas Trees

Each year, the Christmas season sees millions of trees felled, but experts suggest that these forests can be farmed regeneratively, promoting biodiversity

As the festive season approaches, debates around sustainability often turn to Christmas trees. Should we opt for real or artificial?

As you might expect, environmental experts favour real trees — but their reasoning is more complex than it may first appear.

The carbon cost of artificial trees

Artificial Christmas trees have become a staple in millions of homes, particularly in the United States where an estimated 10 million are purchased annually. And their environmental cost is significant.

According to the team from Carbon Trust, “a two-metre artificial tree has a carbon footprint of around 40kg, more than 10 times that of a real tree that’s burned after Christmas”.

A key factor is the production process. Manufactured primarily from polyvinyl chloride (PVC), artificial trees are energy-intensive to produce and rely on petrochemical inputs.

They are also predominantly manufactured in China, necessitating long-distance shipping and adding to their carbon footprint.

Once discarded, these trees are typically non-recyclable and end up in landfills, where they contribute to environmental degradation.

The role the Christmas tree market plays in sustainable forestry

Real Christmas trees, in contrast, come with benefits that extend beyond their festive charm. In the US alone, between 350 and 500 million Christmas trees are cultivated on farms, with roughly 30 million harvested annually.

According to the National Christmas Tree Association, every tree harvested is replaced by one to three seedlings, ensuring a continuous cycle of growth.

These tree farms also serve as vital habitats for wildlife, fostering biodiversity.

The preservation of these lands is critical, particularly in light of increasing pressures to convert farmland to other uses.

Why real trees offer a greener alternative

Real Christmas trees offer a more sustainable option and their positive impacts begin right from first growth.

As living trees, they absorb carbon dioxide, releasing oxygen and contributing to the fight against climate change. This natural process positions trees as one of the most cost-effective tools in carbon emission reduction.

Beyond carbon sequestration, the business of real Christmas trees supports forest conservation.

Tree farms not only provide festive greenery but also sustain habitats for wildlife, maintain soil health and support local economies.

Sustainable disposal and second lives

Unlike their artificial counterparts, real trees have multiple environmentally friendly disposal options. Many communities offer recycling programmes, repurposing used Christmas trees for conservation projects such as erosion control, wildlife habitats and mulch production.

Artificial trees, however, typically lack these options. Due to their mixed-material construction, they rarely qualify for recycling, meaning their lifecycle ends in a landfill, contributing to waste and pollution.

The role of sustainable forestry

Some may question whether cutting down trees at all is a step backward for environmental efforts. However, experts argue that sustainable forestry practices can enhance conservation.

Certification programmes like the Forest Stewardship Council (FSC) ensure that trees are harvested responsibly, balancing economic needs with ecological preservation.

It is said that forests farmed for trees can store as much carbon as unmanaged ones when maintained properly. By supporting sustainably-managed tree farms, consumers can contribute to both climate solutions and biodiversity conservation.

The commercial viability of these farms also protects private forests, which make up over half of US forested land. Without economic incentives, many landowners might turn to deforestation for development, making tree farming an essential tool for forest preservation.
