According to Carbon Trust, real Christmas trees are better for the environment than artificial ones. The best option is a potted tree which you yourself replant and re-use year after year.

Real trees absorb carbon from the atmosphere & emit oxygen while they are growing. Artificial Christmas trees are made from plastic (mostly PVC film), which is produced from carbon intensive oil. The subsequent manufacturing process of the tree also has high emissions.

Real trees are biodegradable. Artificial trees are usually made of non-recyclable materials, giving us synthetic waste to dispose of. However, a real Christmas tree could come wrapped in plastic & in a plastic pot, which could be recyclable at best, otherwise sent to landfill. Biodegradable plastic comes with its own issues, see Would Using Biodegradable Plastics Solve the World’s Plastic Problems?” (OneSharedEarth, 2018).

Buying a locally grown tree reduces emissions from transport. On the other hand, driving far to get one or buying one grown far away, will increase its emissions. Although artificial trees are usually shipped from China, ocean shipping makes the transport efficient. However, they are then transported to shops & homes.

A 2 metre artificial tree has a carbon footprint of around 40kg CO2e. For a 2 metre tall real tree, the carbon footprint is 16kg CO2e if it ends up in landfill to produce methane, which is a highly potent greenhouse gas. Instead, if it is burnt, carbon dioxide that it stored up when it was growing is released so there's no net increase, but the carbon is released immediately, which is not ideal. Having it chipped to spread on the garden significantly reduces the carbon footprint and contributes to building of soil carbon. See Christmas Trees” (, 2019) for the many local authorities that provide this service.

Christmas trees are usually not harvested from wild forests, but grown as part of well managed forests or farms. In fact, the Christmas tree market gives an economical reason to maintain these farms. A 2 metre tree is estimated to be grown for 10-12 years & provides shelter for birds & wildlife when it is growing. When they are cut while leaving roots in the ground, that enables soil carbon storage. Having said that, there have been illegal logging practices & dangerous working conditions associated with Christmas tree farming. Buying Forest Stewardship Council (FSC) trees is a better choice to avoid these issues & their trees are grown minimising the use of pesticides.

There are now options to rent a living Christmas tree. But the best option is a potted tree which can be replanted and re-used year after year, and will reduce issues like water & pesticide use & transport emissions.

If you already have an artificial tree, you can minimise its environmental impact by continuing to use it for as long as possible, at least 10 years to keep its environmental impact lower than that of a real tree. If you keep it for longer, even better.

In the UK, we are estimated to buy around 7mn Christmas trees each year, many of which are grown within the UK itself whilst others are imported. The majority of these trees cannot be easily replanted, but it is generally possible to ‘recycle’ them. Look at your local council’s website and their recycling schemes to find out more. Some places even offer real trees which can be hired and returned.

The obvious advantage of real trees from an environmental perspective is that they are able to absorb CO2 from the environment, while the production of artificial trees is a process resulting in the release of CO2 into the atmosphere. Many people opt for artificial trees over their naturally-occurring counterparts. These trees are often imported from overseas rather than made in the UK itself. In addition, they cannot be recycled as they are made from a combination of different materials. Instead, it might be better to try donating them to a charity shop so that they can be reused.
