Frequently Asked Questions
Is a real or artificial Christmas tree better for the environment?
It depends on use duration and disposal. A real tree composted annually is close to carbon neutral. An artificial tree has a manufacturing footprint of 40-80 kg CO2e that needs 10-20 years of use to break even against composted real trees. Most families replace artificial trees after 6-9 years, before reaching the breakeven.
What happens if I put my real tree in the bin?
Landfilled trees decompose anaerobically, generating methane - a potent greenhouse gas. This turns a near-neutral real tree into a significant emission source. Composting, chipping, or burning (where permitted) are much better options.
How many years should I keep an artificial tree to break even?
Typically 10-20 years, depending on the manufacturing footprint (larger trees have higher footprints) and what you compare against (composted real trees vs. landfilled). Buying a high-quality artificial tree you will keep for 15 or more years minimises its annual effective footprint.
Are there any other eco options?
A potted living tree that gets replanted outdoors after Christmas has essentially zero net carbon footprint. Renting a living tree is available in some cities. Minimal-decoration branches from pruned garden trees or locally sourced wood are also low-impact alternatives.
