4 simple ways to make your holiday season more sustainable
Simple changes to your holiday decorations, gifting or travel can make the festive season more sustainable.
For many people around the world, the holiday season is a time to eat, drink and be merry with family and friends. But between unwanted gifts, energy use and all the travel, the celebrations can create problems for the planet.
Here are four things you can do to make your holiday festivities more sustainable.
1. Buy a real tree
Here's some good news for those who prefer real Christmas trees. Because they're grown on farms, buying a real tree for your house doesn't harm forests, according to the Rainforest Alliance.
Even though they are cut before reaching maturity, the Alliance says they are just as effective at trapping CO2 as any other tree variety. Artificial trees, one the other hand, are mostly made of plastic that has been shipped long distances.
Don't want to cut down a tree? Brits can now rent a living tree just for the Christmas period. The pot-grown trees are returned to the farm in January to continue to grow for the following year.
2. Replace old decorative lights
The environmental impact of the festive season in the developed world is huge. Christmas lights in the United States use more electricity than El Salvador does in a year.
The US Department of Energy calculates Christmas and Thanksgiving decorative lights consume 6.6 billion kilowatt hours of electricity a year, enough to power 14 million refrigerators.
Switching to LED lights can make a big difference in terms of energy consumption and carbon footprints. In fact, LED lights use around 25% of the energy of conventional incandescent bulbs.
3. Choose gifts with care
According to a survey by US consumer website Finder, more than 60% of Americans expect to get an unwanted gift this year. That's 154 million people receiving presents worth a total of over $15 billion, half of which will be re-gifted or taken back to the store.
As the cost of Christmas rises each year, a survey by UK mortgage lender Nationwide found the average family will spend more than $950 on Christmas 2019, almost twice the average UK weekly wage.
One solution could be to reduce the amount of gifts you give and donate to a charity instead. The UK's Charities Aid Foundation says 4 out of 10 people would willingly forego a present if the money was given to charity instead.
4. Reduce your holiday travel footprint
In North America, Christmas traditionally brings airport chaos as people travel to spend the season with family and friends. Last year, a record 25 million people flew for the Thanksgiving holiday in the United States.
The obvious way to avoid CO2 emissions is to not travel at all. But that can be tricky, especially around this time of year. So, when possible, consider taking the train or travelling by car instead. Carbon emissions per passenger for each kilometre travelled are around 285 g for air travel, 158 g on the road, and 14 g for rail, according to European Environment Agency figures.
The IATA says air travel emissions per passenger are decreasing. And if you do choose to fly, the International Council on Clean Transportation recommends flying in economy, where more seats mean less CO2 per passenger, or flying direct or on newer, regular-sized planes, which use less fuel.

"Deepfakes" and "cheap fakes" are becoming strikingly convincing — even ones generated on freely available apps.
- A writer named Magdalene Visaggio recently used FaceApp and Airbrush to generate convincing portraits of early U.S. presidents.
- "Deepfake" technology has improved drastically in recent years, and some countries are already experiencing how it can weaponized for political purposes.
- It's currently unknown whether it'll be possible to develop technology that can quickly and accurately determine whether a given video is real or fake.
The future of deepfakes<p>In 2018, Gabon's president Ali Bongo had been out of the country for months receiving medical treatment. After Bongo hadn't been seen in public for months, rumors began swirling about his condition. Some suggested Bongo might even be dead. In response, Bongo's administration released a video that seemed to show the president addressing the nation.</p><p>But the <a href="https://www.facebook.com/watch/?v=324528215059254" target="_blank">video</a> is strange, appearing choppy and blurry in parts. After political opponents declared the video to be a deepfake, Gabon's military attempted an unsuccessful coup. What's striking about the story is that, to this day, experts in the field of deepfakes can't conclusively verify whether the video was real. </p><p>The uncertainty and confusion generated by deepfakes poses a "global problem," according to a <a href="https://www.brookings.edu/research/is-seeing-still-believing-the-deepfake-challenge-to-truth-in-politics/#cancel" target="_blank">2020 report from The Brookings Institution</a>. In 2018, the U.S. Department of Defense released some of the first tools able to successfully detect deepfake videos. The problem, however, is that deepfake technology keeps improving, meaning forensic approaches may forever be one step behind the most sophisticated forms of deepfakes. </p><p>As the 2020 report noted, even if the private sector or governments create technology to identify deepfakes, they will:</p><p style="margin-left: 20px;">"...operate more slowly than the generation of these fakes, allowing false representations to dominate the media landscape for days or even weeks. "A lie can go halfway around the world before the truth can get its shoes on," warns David Doermann, the director of the Artificial Intelligence Institute at the University of Buffalo. And if defensive methods yield results short of certainty, as many will, technology companies will be hesitant to label the likely misrepresentations as fakes."</p>
Context is everything.
The COVID-19 pandemic has introduced a number of new behaviours into daily routines, like physical distancing, mask-wearing and hand sanitizing. Meanwhile, many old behaviours such as attending events, eating out and seeing friends have been put on hold.
