Long-haul travellers need to stay home for sake of climate
• Tourism industry faces a crisis if it is to achieve net zero by 2050
DESTINATIONS IN THE GLOBAL SOUTH ARE ALREADY FEELING OUTSIZE HUMAN EFFECTS FROM CLIMATE CHANGE
If you are concerned about climate change and wondering whether you should travel to far-flung places as often as you used to before the Covid-19 pandemic, it is a valid question. You are not going to like the answer.
An estimated 11% of global greenhouse gas emissions are due to tourism, and that is predicted to double by 2050, the year scientists have forecast as the tipping point for all sorts of ecological disasters. By then, our planet will have warmed 1.5°C above preindustrial times. By the end of the century, the figure looks to be 2°C , with that halfdegree making a huge difference. If emissions are left unchecked, this warming will accelerate, bringing forth a distinctly heightened level of cataclysmic weather patterns.
So how can tourism fix its emissions problem? It just needs 100% sustainable aviation fuels by 2050 to power air travel. It can grow, mostly by increasing the share of shorthaul trips over time — from 69% in 2019 to 81% by 2050 — while global travellers (that’s you) rein in the number of long-distance flights you take every year ... until at least 2050.
Once everybody sticks to this impossible-to-imagine scenario, you can return to jetting back and forth across the globe with impunity. You could do it even more if you like.
Those are the unsurprising yet troubling findings of a report released on Monday from the Travel Foundation released in alignment with COP27 in collaboration with the Centre of Expertise Leisure, Tourism and Hospitality, Breda University of Applied Sciences, European Tourism Futures Institute, and Netherlands Board of Tourism & Conventions. The longest-distance flights are defined as round trips of more than 16,000km — that is, New York to Cairo, or London to Bangkok. They are the hardest to decarbonise, the report explains, which is why they must remain static at 2019 levels for the next 27 years in order for tourism to reach net zero. (Net zero means to curb emissions as close to zero as possible.) This is despite simultaneously increasing other modes of low-emission transport, such as electric cars, high-speed trains and hydrogen buses.
“Our hope is to spark further dialogue and to help destinations and businesses recognise that the business-asusual scenario is not all that likely in the future,” says Jeremy Sampson, CEO of the Travel Foundation. He notes that the report’s scenario comes with its own pain points and is not all that realistic.
CALCULATION
The report focuses on movement from point A to point B and does not take into account other huge sources of emissions in the travel industry, such as cruises or embodied carbon in hotel construction.
Paul Peeters, professor of sustainable tourism transport at Breda, performed simulations for the report using the Global Tourism and Transport Dynamic Model tech platform he developed in 2017, plugging in data he has been gathering since 2005. His model considers the overall tourism industry, including all overnight trips — defined as at least one night away from home (international or domestic) for the purpose of vacation, business or visiting friends and relatives. It addresses up to 20 distances travelled, accommodation providers and major transport modes, minus cruise ships, to 2100.
Seven optional factors are thrown into the simulation: sustainable aviation fuel, electrification and energy efficiency, infrastructure improvements, taxes, offsetting, travel behaviour and travel speed. The first three (fuel, energy efficiency, infrastructure) reduced emissions the most, but even maximising them was not sufficient to reach net zero by 2050 when accounting for the certainty that tourism will grow. Even maximising all seven factors proved insufficient, Peeters says. Hence the need to cap the growth of long-haul aviation at 2019 levels.
“Technically, it can be done,” he says. “The economy is growing. Your freedom to travel is basically the same, but the distances change. You should not fly six times per year from the US to Europe.”
Left unchecked, long-haul aviation is expected to quadruple its emissions by 2050 to reach 41% of total tourism emissions, the report shows. As it stands, long-haul flights are not yet back at 2019 levels, Peeters said.
The larger takeaway of the report: it may be possible to act now, but the near-impossible extremes required to reach net zero by 2050 confirm that the tourism industry faces a crisis.
Every sector of travel would have to throw all it has behind climate action without delay to make a dent in emissions. Travellers will need to think harder and care more about how and where they travel.
Like most industries, tourism remains in slow motion as it begins to tackle its negative effect on a planet whose health is vital to it.
After 18 years of relative inertia since the tourism industry made its first climate promises, 300 initial signatories, including the UN World Tourism Organization and the World Travel & Tourism Council, committed to the Glasgow Declaration on Climate Action in Tourism in 2021 to halve tourism’s emissions by 2030 and eliminate them to near zero by 2050. This is in line with the 2015 Paris Agreement among 196 countries to reduce global warming, and to which the US just recommitted.
As this push accelerates, travel businesses and destinations are beginning to change how they operate. They intend to lead travellers — you — to experience places and activities differently.
Major holiday and tour operator TUI, for instance, began offering new sleeper train trips as a substitute for six short-haul routes in Europe. Tour operator Sunweb, in the Netherlands, is also focused on offering overnight train trips to Belgium and the French Alps this winter and to the south of France in the summer of 2023.
On a far more microlevel, Ziptrek is the first adventure outfitter in Queenstown, New Zealand, to offer consumerfacing labelling to show customers what their emissions would be when selecting zipline tours. “It’s the right thing to do, and it’s the trajectory of tourism,” says Trent Yeo, executive director at Ziptrek Ecotours.
This is admirable. When it comes to climate change, we are all in this together. But it is minuscule in the face of the systemic changes that governments and tourism boards need to enact.
The trick for the traveller will be to learn about your carbon footprint, if you do not already understand it, and to be able to sort among companies that are making a real effort versus those that are greenwashing their way into your travel decisions.
Booking.com, powered by climate-tech platform Chooose, will soon show carbon emission listings on flight and hotel results, allowing travellers to filter lower carbon emission results from a range, for instance. “And then to take it one step further and include individual travellers, who are the bookers, to understand their carbon footprints early on in the decision process,” says Andreas Slettvoll, CEO of Chooose.
Iberostar Group released its own ambitious decarbonisation road map on November 8 at COP27, which is partly marketing (it wants 60% of guests to choose the brand for its sustainability actions by 2025) and partly action (a 2030 net-zero goal and nature-based carbon compensation projects at its 97 resorts across four continents).
ECO-EFFICIENCY
Because consumers alone will not solve anything, governments, hotels, tour operators, cruise operators and the aviation industry need to lead with additional policies to encourage better decisionmaking. To that end, the Netherlands is considering an eco-efficiency index of its visitors, says Ewout Versloot, a sustainability strategist working with the tourism board. This means dividing the amount of revenue a tourist brings in by the amount of carbon dioxide emissions the tourist triggered travelling there. That index would indicate which long-haul market the government should direct marketing dollars towards to help reduce emission effects.
“If we realise that we might be less dependent on long-haul source markets, maybe we can identify those markets that might be most valuable to us,” Versloot adds, noting this approach is part of the Netherlands’ road map to climate-neutral tourism that was released in September.
Destination picking brings up the inevitable inequities that tourism-dependent destinations and regions in the global south would face — for instance, Barbados, Indonesia and Thailand, as well as all of Africa and South America. When richer countries are the main culprits in emitting carbon dioxide, who should bear the economic loss of diverting tourist dollars to destinations closer to them?
“Do we need to cap the global south or do we need to cap some of the highest-volume airports in that long-haul aviation? This is exactly the discussion we need to be having in this unprecedented, collaborative way,” says Megan Morikawa, global director of sustainability at Iberostar Group.
“If we’re making assumptions on who the winners and losers should be, we’re going to end up making decisions that might make equity issues even worse.”
Destinations in the global south are already feeling outsize effects from climate change and vainly awaiting compensation from richer nations.
Worsening the problems are a lack of access to greener technologies that Europe can access and to funding for tourism businesses to adapt and decarbonise rapidly.
“Tourism ‘as a force for good’ should be stripping out carbon,” Sampson says. “A shift to less flying around during a period of time has the potential to make tourism genuinely more local and a better experience for visitors. This type of tourism can also deliver better benefits for the community while reducing some of the unintended burdens from tourists.”
What is clear from this report is that drastic changes are needed in the tourism industry. Individual travellers should question their choices, such as long-haul trips, but it is the travel industry that needs to let go of the status quo.
For now, the sector is making big promises while changing little. Without meaningful progress, your trips of a lifetime may become exactly that — viable only as you live and not for the generations to come.
