Deciding between a live or artificial Christmas tree is not just a matter of aesthetics, but also of environmental sustainability. Considering the carbon footprint of each can help you choose the more environmentally responsible option.

Live Christmas Tree: An Ecological Advantage When Disposed of Properly

• Average carbon footprint: 3.5 kg CO₂e if the tree is composted or used as mulch. However, this value can rise to 16 kg CO₂e if the tree is landfilled, where it releases methane during decomposition.
• Benefits during growth: During 7–10 years of growth, a living tree absorbs approximately 18 kg of CO₂ and produces oxygen.
• Storable and biodegradable: When properly processed, the tree can be used to create mulch or compost, minimizing its environmental impact.
• Transportation: Importing trees long distances increases the carbon footprint, so locally grown trees are a more environmentally friendly choice.

Artificial Christmas Tree: A Long-Term Solution with High Initial Costs

• Average carbon footprint: 40 kg of CO₂e to produce one tree, which is made from petroleum-based plastics (PVC) and metals. Most of this is produced in Asia, which increases emissions from transport.
• Sustainability: To achieve a lower carbon footprint than live trees, an artificial tree must be used for at least 10–12 years.
• Recycling: Artificial trees are difficult to recycle and can remain in landfills for hundreds of years, further exacerbating their environmental impact.

Comparison of the carbon footprint using the example of a two-meter tree:

1. Living tree:
   • When composting: 3.5 kg CO₂e.
   • At the landfill: 16 kg CO₂e.
2. Artificial tree:
   • Single use: 40 kg CO₂e.
   • Use for 10 years: Approximately 4 kg CO₂e per year.

Recommendations for an ecological choice:

1. Living tree:
   • Choose a tree from a local plantation to minimize transportation emissions.
   • After the holidays, compost it or donate it to recycling programs.
2. Artificial tree:
   • If you already own an artificial tree, use it for as long as possible (at least 10 years).
   • Consider purchasing a tree made from recycled materials.

If you prefer a lower carbon footprint and are careful about disposing of it properly, a live tree is a more environmentally friendly option. An artificial tree can be sustainable, but only if used for a long time. For even greater sustainability, you can consider alternatives such as potted trees or decorations made from natural materials.
