You Can Burn Your Old Cable Bill – Here’s Why [OST Main Logo mobile]( [LOGO OST]( What would it take to really make the World Cup, and other sports mega-events, a genuine part of a low-carbon world? H Humanity is deep in the throes of the World Cup. Billions of people are expected to tune in to at least one match of the 2022 Qatar tournament – a significant proportion of the global population. With reach like this comes scrutiny, including on the climate impact of such a massive event. Qatar has built seven new stadiums and refurbished an eighth for the World Cup finals. It has also built a new airport, a metro system, new roads and around 100 new hotels. Some 1.2 million visitors are expected, the vast majority arriving by air, with many staying in nearby cities like Abu Dhabi and Dubai, then taking shuttle flights to matches. In an attempt to make this World Cup the first that is "fully carbon neutral", Qatar has promised to offset its carbon emissions (Read more about the limitations of carbon offsetting). But many are not convinced. One analysis found the tournament could end up with a carbon footprint three times higher than it claims. Another found the carbon footprint attributed to the new stadiums were in reality about eight times higher, and heavily criticised a new carbon credit standard set up by organisers for not complying with international standards. A set of advertising complaints have now been filed across several European countries over Fifa's promotion of its carbon neutrality claims, while several footballers have sent an open letter to Fifa asking it to "ditch" the claim and only use offsets as a last resort. It is hard to think of a different sector that attracts the attention of literally billions of human beings across the globe – Suki Hoagland The scale of the challenge is undeniably vast. Some might question whether the World Cup as we know it now – with teams, fans and officials flying long distances and massive infrastructure development – can ever become sustainable. Would the basic model of the event need to change to become greener, and if so, what might that look like? "It is hard to think of a different sector that attracts the attention of literally billions of human beings across the globe," says Suki Hoagland, a lecturer at the Stanford Doerr School of Sustainability in California. "It will be a bellwether of how the rest of society is responding."

But this year's tournament is a step-change. One estimate calculated the current Qatar event could generate as much as 10 million tonnes CO2e – an amount similar to the annual emissions of Armenia. It's a huge amount, albeit still a small fraction of global emissions. But since emissions across the planet as a whole need to be halved by 2030, Fifa should also, at the very least, halve its emissions by 2030, argues Khaled Diab, communications director at Carbon Market Watch and editor of its report on Fifa's carbon neutrality claim. Considering that sport is "not a life-or-death sort of activity", perhaps it should be even more ambitious than this, he adds. What is CO2e? CO2 equivalent, or CO2e, is the metric used to quantify the emissions from various greenhouse gases on the basis of their capacity to warm the atmosphere – their global warming potential. There are two major areas of environmental impact from the World Cup. Number one: transport. Flying by air is incredibly carbon-intensive, making fan flights the largest source of emissions from every major international sporting event, says Madeleine Orr, a lecturer at Loughborough University London and founder of the Sport Ecology group of academics. And then there is the gigantic energy and material footprint of building new stadiums, along with the transport networks and hotels to accommodate hundreds of thousands of fans. These two areas overlap because they are largely around the movement and accommodation of fans, not the footballers and their entourage. Better buildings Much can be done to reduce the environmental impact of new buildings, of course. One obvious starting point is sourcing low-carbon energy to power them, such as by building solar projects nearby. "Your energy consumption should all come from renewable energy," says Dale Vince, owner of Forest Green Rovers football club in the UK and founder of Ecotricity, a renewable electricity company. "But at the same time, you should be super-efficient with that, using low consumption devices like LEDs for floodlights, for example, and energy efficient appliances." To lower emissions, construction could move away from conventional concrete-based structures, says Vince. Carefully considering the connections between key buildings in the World Cup could also help lower emissions, with electric buses, electric cars, personal mobility scooters or simply walking prioritised. Vince envisions a green World Cup based in stadiums built entirely out of wood, all situated close together "so that if you fly in, you're in the World Cup village, and you can watch every game you want to without travelling other than by electric bus". Moving matches Another way to reduce the huge footprint of building many new stadiums would be to avoid building them in the first place. One option here could be reducing the number of teams playing in the final tournament, says Russell Seymour, executive chair at the British Association for Sustainable Sport. Having hubs where the top teams from each region come together for a smaller final tournament would reduce impacts, he notes. The environmental pros and cons of Christmas trees go far beyond the climate impact of "real or plastic", scientists say. So what's the best choice for a green Christmas? I In 1800, Queen Charlotte, the German wife of King George III, set up what is thought to be the first Christmas tree in England, at Queen's Lodge in Windsor. Decorated Christmas trees already had a long history in Germany, but they soon became a fashionable part of the festive season for the English upper classes, and by the 1850s were a common sight across the UK. Some two centuries later, the now cherished tradition of planting a newly cut tree in the middle of living rooms and covering it with lights and baubles is still alive and well across much of the world. Today, over eight million Christmas trees are sold annually in the UK, and an estimated 25-30 million are sold in the US. Real trees may also be coming back into fashion among younger generations – one recent US survey found millennials are 82% more likely than baby boomers to get a live tree. A millennial myself, I certainly fit this trend. I love real Christmas trees but have had countless conversations (and internal debates) about whether getting one is overindulgent wastefulness or an essential – and ultimately environmentally negligible – part of Christmas. I do think there's a lot more nuance to it, than just, 'Oh, we're cutting down a tree and removing it' – Alexandra Kosiba As I have delved further into the topic, though, I've found their assumed negative environmental impact may not be as clear cut as I once thought. These conversations often centre on the relative carbon footprint of real compared to plastic ones, but researchers say their wider influence, good or bad, goes far beyond this. "I do think there's a lot more nuance to it, than just, 'Oh, we're cutting down a tree and removing it'," says Alexandra Kosiba, a forest ecologist at the University of Vermont Extension. After all, before it is cut down and displayed, a Christmas tree is grown – on land that might otherwise be used for different purposes. In Vermont, for example, says Kosiba, Christmas tree plantations support the local economy and help to keep land as a rural landscape. How we use our land has become especially important in the face of two pressing and deeply connected environmental crises: biodiversity loss and climate change. Forests are a huge part of such beneficial land use. "Well-managed forests really play a huge role in the climate solution," says Andy Finton, landscape conservation director at The Nature Conservancy, a US-based environmental non-profit. "Trees of all sorts are pulling carbon from the atmosphere, and storing it and reducing the amount of carbon pollution and thus the pace of climate change." Christmas trees are grown for around 10 years before harvesting, so for every one cut down each year a further nine tend to stay standing (Credit: Ben Hasty/Getty Images) Christmas trees are grown for around 10 years before harvesting, so for every one cut down each year a further nine tend to stay standing (Credit: Ben Hasty/Getty Images) Christmas trees are certainly not a hugely significant use of land, or a big player in the global carbon cycle, especially compared to timber production or crops like maize or wheat. But they do provide an interesting area to consider, in part because many humans have far more direct engagement with them than perhaps any other forest product. "There's a lot of folks that don't interact with nature a lot," says Kosiba. "It is pretty cool to think all these people are bringing a tree [...] into their house [and] sort of revering it, and appreciating it." This festive appreciation may be a good opportunity to consider the wider role of different trees, and how and where they are grown. Christmas trees are typically young spruce, fir or pine trees from plantations, which means their environmental impact will always very much depend on what might be grown on land instead. It goes without saying that old growth forests, peatlands and other native habitats should never be used to plant Christmas trees. The plantations are grown for roughly 10 years before harvesting, meaning that for every tree cut down one year, another nine or so stay standing. "It's quite nice as a way of maintaining a set of trees, because you always need the new trees coming through to be harvested the following years," says John Kazer, footprint certification expert at the Carbon Trust, a UK-based environmental consultancy. Especially if the Christmas tree farm is part of a much larger landscape or a mosaic of habitat types, including mature, larger, intact forests, I think there's a real ecological niche that it's fulfilling – Andy Finton Christmas trees are not included in the EU pledge to plant three billion additional trees by 2030, as they are considered too short lived. "They are cut down more often than timber harvest or, of course, natural old growth forests," says Paul Caplat, an ecologist at Queen's University Belfast. "So there's not a lot of time for biodiversity to settle in and grow healthy populations." However, research has shown that Christmas tree plantations can provide a boost to biodiversity – especially in areas where it has been declining as agriculture becomes more intensified. This is because the plantations tend to have open habitat structures rich in bare ground, which can allow higher accessibility to food resources, while their trees can provide farmland birds with decent nesting conditions. They also tend to be less intensively managed than much industrialised agriculture, which also helps with food availability, while their fences can keep out the disruption from humans and dogs "Species that would have used a more extensive form of farming landscape in the past, but don't find all the resources they need in the more intensified agricultural setting, will find what they want in the Christmas tree plantation," says Caplat.

[Click here to find out why »]( And then there is the carbon. Like any other tree, Christmas trees capture carbon as they grow. When they are cut down, they will begin to release that carbon. "There's a continuous process of growth and of taking carbon out of the atmosphere, which is a positive thing," says Kazer. However, as all the carbon absorbed by the tree will eventually be returned to the atmosphere as the tree dies, there is no overall removal of carbon, he adds. What is CO2e? CO2 equivalent, or CO2e, is the metric used to quantify the emissions from various greenhouse gases on the basis of their capacity to warm the atmosphere – their global warming potential. It’s also worth putting the amount of carbon involved in having a Christmas tree in context. The Carbon Trust estimates that a 2m-tall (6.6ft) Christmas tree burnt after use emits only 3.5kg carbon dioxide equivalent (CO2e) – roughly 0.2% of the emissions from a return flight from London to New York. A tree of the same size that ends up in landfill has a carbon footprint of 16kg of CO2e – equivalent to 1% of that return flight, or roughly two hamburgers. How people dispose of their Christmas trees after use is usually the single most important carbon consideration. The worst-case scenario happens when Christmas trees end up in landfill: the anaerobic conditions are conducive to the same carbon being released as methane – a greenhouse gas some 80 times more potent than carbon dioxide on a 20-year timescale. Whether or not a tree ends up in landfill has by far the largest impact on its carbon footprint: a tree that ends up in landfill emits some 4-5 times as much carbon as one that doesn’t, according to Carbon Trust figures. Ideally, if a tree is still alive with its roots, it will be replanted. A decent alternative is ensuring the tree's carbon is released slowly back to the atmosphere as CO2 – as happens if the tree is chipped and spread on a garden or park, or composted. If the tree is burned for energy, meanwhile, the carbon it contains will be emitted straight back to the atmosphere as CO2. The BCTGA also recommends checking whether the place you bought the tree from offers recycling services, allowing it to be chipped and returned to the fields where it grew. Whole trees can even be used as habitat restoration tools on riverbanks and along shorelines to prevent erosion. In Vermont, where old Christmas trees are used for everything from biomass burning for energy to goat food, "we're also seeing folks using them in stream restoration," says Kosiba. "They're great at catching dirt and debris, and creating little barriers and pools for fish: a lot of it is mimicking what a beaver would do." Aside from disposal, Christmas trees produce greenhouse gases through the fertilisers used to grow them, which are made using fossil fuels and produce nitrous oxide, another powerful greenhouse gas. Meanwhile, managing and harvesting the forests uses fuel, as does transporting the trees to their final location.

Some businesses now offer Christmas tree rentals – allowing you to borrow a potted tree for a few weeks over Christmas. "It fits perfectly in the sustainability approach of reduce, reuse before recycle," says Caplat. Carbon Count The emissions from travel it took to report this story were 0kg CO2. The digital emissions from this story are an estimated 1.2g to 3.6g CO2 per page view. Find out more about how we calculated this figure here. For those with the space, another great option is to buy a pot-grown tree for Christmas then keep it in your garden till the following year – perhaps even planting it permanently once it gets too large. "It's hard to imagine a better solution," says Finton, who advises getting a local species that will thrive in the area you live in, and making sure to keep it well watered when inside. And then, of course, there is the question of whether simply to opt for an artificial tree. These take hundreds of years to break down in landfill, but could be lower carbon overall than buying multiple real trees if reused for long enough. The Carbon Trust estimates the carbon footprint of plastic Christmas trees at around seven to 20 times that of real tree, depending on a range of factors such as whether the real tree went to landfill or how far people travelled to pick it up. If you have an artificial tree, the key is to reuse it for as many years as possible, says Kazar. "It takes a lot of effort to make those trees and to get them over to the UK," says Kazer. "And at the moment, they're quite hard things to recycle, because they're quite complicated." It's a drop in the ocean, but like any drop, it can be very useful as a model of how to approach things – Paul Caplat Even if Christmas trees are not the environmental bane of the festive period, and may even be providing some ecological benefits, we can still vastly improve their management. We can reduce or eliminate the fertilisers and pesticides used to grow them (including by accepting "wonkier" trees), and ensure forests are certified by schemes such as the Forest Stewardship Council, which verifies sustainable sourcing of forest products. We can also try to grow them near to cities, in places where the alternative options for that land use are worse, and consider using pot-grown trees instead of cut trees, then planting them permanently. We can prioritise buying local trees to reduce travel emissions, and we can definitely aim to ensure that no Christmas trees end up in landfill. "It's a drop in the ocean, but like any drop, it can be very useful as a model of how to approach things," says Caplat. "[Christmas trees] reach out in the areas of the climate change and biodiversity crisis, cost, welfare, affordability and everything basically. Because it's something that pretty much everyone wants." However, research has shown that Christmas tree plantations can provide a boost to biodiversity – especially in areas where it has been declining as agriculture becomes more intensified. This is because the plantations tend to have open habitat structures rich in bare ground, which can allow higher accessibility to food resources, while their trees can provide farmland birds with decent nesting conditions. They also tend to be less intensively managed than much industrialised agriculture, which also helps with food availability, while their fences can keep out the disruption from humans and dogs "Species that would have used a more extensive form of farming landscape in the past, but don't find all the resources they need in the more intensified agricultural setting, will find what they want in the Christmas tree plantation," says Caplat. Studies have found Christmas tree plantations may offer refuges for declining farmland birds like yellowhammers in intensive agricultural areas (Credit: Andrew Howe/Getty Images) Studies have found Christmas tree plantations may offer refuges for declining farmland birds like yellowhammers in intensive agricultural areas (Credit: Andrew Howe/Getty Images) In one recent study in Germany, for example, researchers found Christmas tree plantations could represent important refuges for declining farmland birds such as yellowhammers and common linnets in intensive agricultural areas. The results chime with another 2018 study in Sauerland in Germany which found the plantations are important strongholds for woodlarks. Meanwhile, a study in Belgium found that beetle diversity – including of threatened species – was higher in Christmas tree plantations than maize fields, although lower than in spruce plantations for timber, which are left to grow for longer and use less fertilisers and pesticides than Christmas trees. Meanwhile, in naturally forested areas of the north-east US, younger, open forests like Christmas tree plantations can provide higher concentration of insects or grasses to support birds and mammals in certain parts of their lifecycle, says Finton. "Especially if the Christmas tree farm is part of a much larger landscape or a mosaic of habitat types, including mature, larger, intact forests, I think there's a real ecological niche that it's fulfilling."

How climate change has altered Christmas How Dickens made Christmas white Of course, Christmas trees are typically treated with plenty of pesticides and especially fertilisers to keep them aesthetically pleasing, says Caplat, which has its own impact on the environment. A study led by landscape ecologist Merle Streitberger from Osnabrück University in Germany found that organic Christmas tree plantations had improved habitat structure and plant species diversity compared to conventional ones, and recommended a reduction in herbicide in particular. Importantly, however, in some cases sites used to grow Christmas trees could be seeing far worse uses environmentally, says Caplat. Areas close to cities, for example, could find alternative uses as parking lots, he says. Kosiba similarly notes that in the rural areas of the northeastern US, where forests are often being lost to sprawling development, Christmas tree farms can give landowners an important diversified income. "It allows people to live in these places, manage and work in their land," she says. In short, if a landowner has an economically viable Christmas tree farm, they're incentivised to keep that land in "that natural, open state", says Finton. "That provides an incentive to keep that land open and not to, for instance, sell land to a situation that might end up in a strip mall or a subdivision or housing development."
