With December's arrival, many people prepare for Christmas by selecting their tree, which is a festive home centerpiece. The joy of presents under the tree is unmatched. However, choosing the right size, lights, and decorations can stress even the most ardent yuletide enthusiast.

A significant dilemma is opting for a natural fir or an artificial tree, particularly for those aiming to reduce their carbon footprint. Here are what experts say about choosing the perfect Christmas tree based on science, emphasizing that bigger isn't necessarily better.

Real Vs. Fake Christmas Tree: Which One Is Better?

The initial decision between a real or artificial Christmas tree is crucial, and generally, real trees are considered more environmentally friendly. Artificial trees, predominantly made of non-recyclable materials like plastic, contribute to landfill waste and have higher greenhouse gas emissions compared to real trees.

Professor Ian Rotherham, an ecologist, emphasizes that the carbon footprint of artificial trees is particularly significant if imported and only used once, especially when manufactured abroad.

While artificial trees can be reused, real trees can also be repurposed by repotting in the garden or returning them to suppliers. The environmental impact of a real tree depends on post-Christmas actions. Professor Rotherham suggests buying a real tree in a pot, utilizing it over several years, and eventually planting it outdoors to offset some carbon footprint from other Christmas activities.

In conclusion, the environmental advantages of real trees, when appropriately managed post-Christmas, make them a preferable choice over artificial trees, especially when considering the latter's non-recyclability and significant carbon footprint if imported and used briefly.

Are Big Christmas Trees Better?

When it comes to Christmas tree height, six-footers are a popular choice due to their compatibility with most homes, although the ideal size depends on available space.

Larger trees pose potential hazards as their branches extend further, emphasizing that bigger doesn't necessarily mean better. Adequate space is crucial for branches to settle properly, ensuring longevity with proper care, according to Ms. Kusak.

Some tree vendors offer stands with water reservoirs to extend the tree's life during the festive season. Proper hydration, with trees potentially consuming 2-3 pints (1-2 liters) of water daily, depending on size and indoor conditions, is essential.

However, the necessity of a water stand depends on the tree's cultivation methods, and treated trees exhibit reduced moisture loss and needle drop, as highlighted by Professor Rotherham.

The choice of a six-foot tree is popular for fitting most homes, emphasizing the need for adequate space. Ensuring proper care, including hydration and considering the tree's treatment, contributes to its longevity and appearance throughout the festive season.

Deck the Halls Sustainably: Opt for Eco-Friendly Decorations and LED Lights

When adorning your tree, opt for environmentally friendly paper or wooden decorations instead of plastic, as plastic contributes significantly to environmental harm when discarded. Plastic waste has a prolonged breakdown period in landfills, posing a threat to the environment and water systems.

Choosing eco-friendly options like LED lights, consuming less energy, and having a longer lifespan, aligns with sustainability goals and reduces carbon emissions.

After the festive season, consider reusing decorations for future Christmases. If repotting the fir is not feasible, contact the council for recycling options, avoiding burning or landfill disposal.

Recycling the tree as a woodchip ensures a return of materials to the soil, minimizing immediate atmospheric impact, whereas burning releases carbon dioxide and other pollutants into the air, cautions Professor Rotherham.
