Sustainable travel: How to cut emissions and keep flying

In 2017 alone, air transport generated 859 million tonnes of the world’s carbon emissions. In reality, this accounted for just 2 percent of global CO2 emissions, yet it’s no surprise that people are reevaluating their travel habits. The good news is sustainable air travel is no longer a flight of fancy, it’s here and Sweden is at its helm.

Despite significant advances in technology over the last ten years, biofuel – which is derived from renewable plant and animal materials and emits 80 percent less carbon than fossil fuels – has retained a near-mythical quality.

It’s time for that myth to be dispelled, says Lena Wennberg, Head of Environment at Swedavia, Sweden’s largest airport operator.

“There are already Swedish domestic airlines offering flights using biofuel,” she told The Local. “Like BRA for example. All you have to do is tick a box, and for an extra SEK 300 ($34), you have an hour of biofuel.”

With most of Sweden’s domestic flights clocking in at around an hour, sustainable options are available for environmentally-conscious flyers.

Swedavia, which operates ten of Sweden’s airports – including two of the country’s largest, Stockholm Arlanda and Göteborg Landvetter – is at the helm of what some are calling a ‘biofuel revolution’. Leading by example, it already uses biofuel to cover around 15,000 of its own domestic business flights each year. Now that biofuel is ready for commercial production, the operator is ready to scale up. Significantly.

“Our goal is for our own activities to become fossil free at all of our airports by 2020,” says Wennberg. “By 2025, all flights are to be refueled with 5 percent biofuel. And by 2030, all our domestic flights will be fossil free. All of our airports have been carbon neutral since 2006 – we compensate by buying carbon offsets that ensure carbon emissions are being prevented at other sites.”

These are challenging targets. To put them into perspective, Norway – presently the world leader in sustainable air travel – aims that all flights will contain a minimum of 0.5 percent biofuel in 2020.

But Wennberg is keen to point out Sweden is making serious headway.

“We’ve already reached our goal of zero carbon dioxide emissions at three airports,” she says. “Ronneby Airport, Visby Airport, and Luleå Airport. At Ronneby Airport and Luleå Airport, some of the main activities are operated by the Swedish military, but at Visby Airport all activities are fossil free.”

Swedavia’s success in reducing carbon emissions has attracted keen attention from Singapore’s Changi Airport. In 2018, the operator received a visit from representatives of the airport, airline and the Government of Singapore.

“It's very interesting to see such a strong delegation from the aviation sector, coming just to have a look and see how it works,” says Wennberg.

It seems people want to know: how is Swedavia – how is Sweden, doing it. Of course, along with intrigue, comes skepticism. For many, while Sweden has the technology, the challenge still remains: how to produce biofuel in large enough quantities at an affordable price. Biofuel may have lost its mystique, but who’s going to pay for it?

Crowd-funding biofuel

“Airports and airlines don’t have the margins to pay for biofuel,” says Maria Fiskerud, who is currently a Project Manager for the Research Institute of Sweden (RISE), adding: “It’s too expensive at the moment.”

She explains that the traditional value chain doesn’t support bringing a new product like biofuel to market.

“The producers were saying there was no uptake agreement from the airlines, and the airlines were saying the producers can’t tell us a price.”

But that was four years ago. Recently, Fiskerud says, advances in biofuel technology and the challenge of global warming is inspiring a new way of doing business within the aviation industry.

“We started a kind of crowd-funding,” says Fiskerud. She’s referring to Sweden’s Green Fly Fund – a unique, industry-wide collaboration, founded by biofuel supplier SkyNRG, Nordic Initiative Sustainable Aviation (NISA) and Karlstad Airport.

The Fund, set up in 2015, allows individuals and companies to purchase biofuel for all or part of their flight. Although costs vary slightly and include a 25 percent processing fee, depending on your agreement biofuel flights can cost as little as SEK 100 ($11). The average one hour flight is SEK 400 ($45). Of that money, 75 percent goes on the biofuel itself, while 25 percent goes into further research and development for biofuel production.

The Fly Green Fund website advises that the exact cost of biofuel can’t be confirmed exactly until after purchase, as the market is ‘still immature’. But for Fiskerud, that’s the whole point.

“We want the end user to help us develop and help us with the innovation. Instead of doing something that the end user might not really want.”

The Fund essentially gives customers the power to express their demand and stimulate market growth. In short, if you want to fly sustainably, you can.

Fiskerud has since moved on to a new project, working for one of Sweden’s most innovative research institutes – RISE. But this time her focus isn’t on driving the market. She’s looking to galvanize the aviation sector from within.  

“We’re bringing together as many people from across the industry as we can,” she says. “We want to complement the work being done by the Fly Green Fund – getting everyone under one roof, and to come to the table with real solutions.”

The ‘Innovation Cluster’, which will be launched in spring together with SAS and Swedavia, aims to do away with the traditional value chain completely – in favour of something more collaborative. “We’re building an ecosystem,” Fiskerud explains, “in which we all have to rely on each other. And we have one goal: to get production up and running.”

Currently, Sweden imports its biofuel from California, a cooking oil-based solution from SkyNRG. But, thanks to the research led by Luleå University, Sweden is now in a strong position to start producing biofuel in-house.

“We have more than a large enough feedstock potential from the forests to sustainably produce biofuel for domestic and international flights in Sweden,” says Fredrik Granberg, project manager at Luleå University. “This is not just another pre study. This is something we can do now.”

Granberg is clear that Sweden does not have the forest feedstock available to replace all fossil energy used today in the transportation sector. However, he says, the production potential from a feedstock combination of biomass and renewable electricity is very interesting.

“If we want to do it in a sustainable way for the future, then we need to do it in a smart way. And really try to maximize the forest's value. There’s a lot of work going on to make our processes more efficient.”

But for those who emphasise that reducing carbon emissions is a global challenge, what about flights outside of Sweden?

Other countries are indeed looking at the possibilities of their own feedstock. In the UK, for example, the focus is not on the forest, but on residues produced from waste.  

Some see biofuel as being a bridge to other forms of sustainable air travel – it isn’t the only opportunity to reduce emissions. “Electrical power for example,” says Maria Fiskerud. “People talk about it like it’s science fiction, but Norway has just bought its first electrical plane.”

Stop emissions, not travel

“People are saying that the best way to reduce emissions is to stop flying,” says Lena Wennberg. “But flying is so many good things for so many people. It brings adventure, creates connections – the world is getting smaller and that is a good thing. I don’t think stopping flying is the answer. I want to offer a hopeful message.”

Supporting that message, is an equally hopeful trend. While 859 million tonnes sounds like a huge number, this actually constitutes just 2 percent of the world’s global fossil carbon dioxide emissions. And in the last forty years alone, air travel has become 70 per cent more fuel-efficient.

With booming economies in large developing countries like China and India, it seems unlikely (and unrealistic) that air travel will lessen; however, with climate-friendly options like biofuel becoming more widely available, people can travel with a clean conscience.

“People talk about biofuel like it’s science fiction,” repeats Fiskerud, “but sustainable flying is here now. You can fly using biofuel today.”

Switzerland’s Nestle to spend billions cutting carbon footprint

Less than a week after Switzerland went to the polls on a set of corporate responsibility rules, Nestle has announced it will spend billions on improving its climate compliance.

Switzerland's Nestle to spend billions cutting carbon footprint

Swiss food giant Nestle on Thursday unveiled a multi-billion programme to slash its carbon footprint, aiming to halve emissions by 2030.

As well as targeting zero net emissions by 2050, Nestle's new long-term road map calls for its 800 factories and production sites around the world to switch to 100 percent renewable electricity by 2025.

The conglomerate, which is regularly attacked by environmentalists over things like plastic packaging pollution and deforestation, said it would plant 20 million trees each year over the next decade to help boost reforestation.

In 2018, the world's largest food company emitted some 92 million tonnes of greenhouse gases, it said, adding that was using that as its baseline for measuring progress.

“Tackling climate change can't wait and neither can we. It is imperative to the long-term success of our business,” Nestle chief Mark Schneider said in a statement.

“We have a unique opportunity to address climate change, as we operate in nearly every country in the world and have the size, scale and reach to make a difference,” he said, insisting the company was intent on reducing “our environmental footprint.”

Chairman Paul Bulcke said the group wants to “contribute to a sustainable future for generations to come.”

Nestle, which owns KitKat, Nespresso and Maggi among other brands, said it was working with hundreds of thousands of farmers and suppliers to implement so-called regenerative agriculture practices.

'Something consumers want'

“With nearly two-thirds of our emissions coming from agriculture, it is clear that regenerative agriculture and reforestation are the focal points of our path to net zero,” said executive vice-president Magdi Batato.

Nestle also said it was boosting its plant-based offerings, with several of its vegetarian and vegan brands due to become carbon neutral within a few years.

In total, Nestle said these changes will cost the company some 3.2 billion Swiss francs ($3.6 billion, 2.9 billion euros) over the next five years. That “is a big ticket,” Kepler Cheuvreux analyst Jon Cox told AFP, stressing though that “that has to be put into the perspective of its size.”

All food companies “are going to have spend similar amounts relative to their size to reach commitments on net zero emissions by 2050,” he said, hinting that such investments could be good for business.

“It is a positive as Nestle is leading amongst companies regarding its sustainability commitments,” he said, stressing this is “something consumers want.”

Nestle, whose international brands include Perrier, San Pellegrino and Acqua Panna, is furthermore considering selling its water bottling operations in North America, where environmental campaign groups have criticised its water withdrawal activities.

Greenpeace lambasted Nestle, along with Coca-Cola and PepsiCo earlier this week, for being the world's worst plastic packaging polluters for a third consecutive year.

The environmental group also last year accused the food giant, along with competitor Unilever, of not respecting a 2010 commitment to reach net zero deforestation within a decade, maintaining that the pace of deforestation linked to commodities had instead increased “dramatically”.

Last year, Nestle opened a research institute in Lausanne aimed at studying alternatives to plastic packaging, as it targets 100 percent recyclable packaging by 2025.
