Outdoor Christmas decorations that create greenery or trees that produce more light can be more eco-friendly than indoor ones, according to a new study by the Centre for Ecological Research and Education (CERE).
The study, conducted by CERE and University of Melbourne, found that the trees created by outdoor Christmas lights could have fewer harmful impacts than those created by indoor ones.
In the study, published in the journal Nature Communications, researchers from CERE, the Centre of Excellence for Climate, Atmospheric and Environmental Research (COVAER), the Australian Institute of Tropical Meteorology and Oceanography (AITOM) and the University of New South Wales (UNSW) looked at the impact of the lighting on vegetation.
A study by CEA, conducted in conjunction with AITOM and UNSW, showed that outdoor Christmas lighting can contribute to reducing CO2 emissions and providing a better chance of keeping the planet’s temperature stable.
“We found that indoor Christmas lighting significantly reduces the amount of CO2 emitted by indoor plants, but it also has a direct impact on the amount released by the atmosphere,” says CERE researcher David O’Connor.
When the researchers compared the effects of outdoor lighting with those of indoor lighting, they found that while indoor lighting did have a positive effect on the greenhouse effect, the difference was much smaller for the outdoor lights.
O’Connor says that outdoor lighting was responsible for almost a quarter of the total greenhouse gas emissions in Australia, and about 60 per cent of the CO2 released by plants.
While indoor lighting emitted about a third of the greenhouse gas, outdoor lighting emitted a much smaller amount of greenhouse gas.
“The effect of outdoor lights on CO2 production is very small,” O’ Connor said.
It is unclear if indoor lights are more efficient than outdoor lights, or if outdoor lights emit more greenhouse gas per watt than indoor lights.
The researchers also looked at other factors like whether outdoor lights create more shade or whether they are brighter and more reflective.
According to the study by CELE, there is no evidence to suggest that the outdoor lighting of the last few decades has been beneficial for the planet.
CERA director Dr Chris MacLean says that research suggests that outdoor lights do not need to be set at night to be harmful.
There are a number of environmental benefits associated with indoor lighting.
One of the main benefits is that indoor lights produce more CO2 and more water.
However, there are also environmental benefits that come from indoor lighting when the sun is shining.
For example, the increased light that outdoor light provides also improves air quality, MacLean said.
“In areas with good air quality conditions, we found that when we reduced the number of outdoor light bulbs indoors, the amount that were emitted by plants decreased by an average of 12 per cent.
This was a large improvement over what was emitted by outdoor lights,” he said.
“This was also shown to be true for animals, such as dogs and cats.
Birds that migrate from their traditional habitat into a new environment can be affected by the light from an outdoor tree. “
As an example, in some parts of Australia, there has been an increase in the number and density of species of birds that have migrated from their natural habitat, such a migration of bird species into the landscape.
Birds that migrate from their traditional habitat into a new environment can be affected by the light from an outdoor tree.
This migration is a natural part of bird migration,” MacLean explained.
Even though many people are aware that lighting up Christmas trees could increase their carbon footprint, Maclean says there is still a lot that can be done to reduce the environmental impact of lighting.
“Lighting up Christmas lights may not be as bad as lighting up an artificial tree or tree in your garden, but in areas where there is very little light, this is still one of the major environmental issues,” he says.
“It is still important to consider that lighting lights up an outdoor Christmas tree could actually increase the amount emitted by trees and other plants.”
