Christmas trees, whether real or artificial, have a notable environmental impact throughout their life cycle. Real trees can be biodegradable and help sequester carbon, but their sustainability varies based on growth methods, transportation, and disposal practices. In contrast, using an existing artificial tree until it is no longer usable is often more environmentally friendly than buying a new real tree each year. Many Australians reuse artificial trees, and some businesses offer tree rental services to promote sustainability. Additionally, initiatives like replanting potted trees after the holiday season are emerging, aiming to reduce waste and enhance environmental responsibility. Overall, the decision on which type of tree is more sustainable is not straightforward and requires consideration of individual circumstances.
