  • Sustainable Aviation Fuel: Opportunities for Hong Kong

    Sustainable Aviation Fuel: Opportunities for Hong Kong

    Hong Kong is eyeing sustainable aviation fuel (SAF) as it races to achieve carbon neutrality before 2050.

    Airplane travel is one of the most carbon-intensive activities. In 2023, the aviation industry’s carbon emissions reached 950 megatonnes, accounting for 2.5% of the world’s emissions. To address this issue, sustainable aviation fuel (SAF) has been developed as an alternative to petroleum-based aviation fuel. 

    As announced in the Hong Kong Policy Address 2025, Hong Kong is eyeing SAF. In this respect, the city is planning to develop a SAF industry chain in cooperation with mainland China authorities, adopt specified SAF consumption targets for flights departing from the Hong Kong International Airport by 2030, and build a SAF blending facility to boost competitiveness.

    What Is SAF?

    Instead of petroleum, SAF is made from sustainable feedstock such as municipal solid waste, agricultural residues, oils, and fats.

    The Fischer-Tropsch Synthetic Paraffinic Kerosene is one of the most common types of  SAF. First, the appropriate feedstock, like wood waste, agricultural residue, and municipal solid waste, will undergo a thermochemical process called gasification. During this process, biomass will first be heated to remove its water content and break its structure into simpler molecules. Then, a chain of chemical reactions will happen under high temperature (above 700) in an environment with limited oxygen. As a result, the biomass will be converted into syngas that primarily consists of carbon monoxide and hydrogen. After removing the impurities, the syngas can be fed into the reactor to produce liquid hydrocarbons by undergoing the catalytic chemical reaction. The liquid hydrocarbons can be used as aviation fuel after refining.

    Why SAF?

    There are various advantages to adopting SAF in Hong Kong. 

    First, SAF is a drop-in fuel that can be directly used in current aircraft. It means that there is no impact on the performance, and no modification or extra infrastructure is required. 

    Depending on the type of feedstock and production methods, SAF can be blended with conventional aviation fuel in a range of 10% to 50%, with lifecycle carbon emission reductions of up to 80% compared with conventional fuel. Using SAF can also improve air quality by lowering emissions of sulfur and particulate matter.

    All this makes SAF a great ally in decarbonization efforts globally and in Hong Kong – the city is committed to reducing carbon emissions by 50% compared with the 2005 level by 2035 and achieving carbon neutrality by 2050.

    Developing SAF is also beneficial for businesses. While airlines can reduce the scope one emissions generated by their aircrafts, other companies can also benefit in the resulting reduction of upstream scope three emissions generated by business travel. As a result, these companies can not only lower their carbon footprint but also reduce the risk of financial loss caused by climate change. 

    As required by the Hong Kong Exchange and Clearing Limited, all listed companies in Hong Kong have an obligation to disclose sustainability-related information – better known as Environmental, Social, and Governance (ESG) standards – to the public. Therefore, companies that develop or support SAF can increase their business reputation and attract new investment.

    Challenges

    Although developing SAF is a good solution to decarbonize aviation, it comes with some challenges. 

    Currently, the cost of SAF is about two to three times that of conventional aviation fuel. The reason is associated with the limited feedstock supply. Some feedstock, such as crop and virgin oil-based feedstock, may lead to deforestation, land use change, and biodiversity loss. If forests are removed, a massive amount of carbon dioxide stored in the trees will be released back to the atmosphere. 

    It is also difficult to ensure a consistent supply of feedstocks like solid waste and agricultural residues. This, in turn, means higher production costs. As a result, airlines may continue to use conventional aviation fuel to save costs and avoid increasing ticket prices. 

    Overcoming these challenges requires detailed planning and supportive policies, such as diversified feedstock and production methods and government subsidies. 

    Moreover, global SAF adoption is slow. In 2024, global SAF production accounted for just 0.3% of the total aviation fuel production. It is expected to reach 0.7% of total jet fuel production this year.

    Without government incentives and leadership, research and development as well as adoption of SAF technology will lag behind, hindering progress of the aviation industry’s decarbonization efforts.

    Greenwashing Accusations

    SAF has been described as a form of greenwashing – when companies make misleading statements about the environmental impacts of their products as a marketing tactic.

    In fact, SAF is a vague term. People with an inadequate understanding may think it is a completely sustainable solution that has zero emissions. Unfortunately, that is far from the truth. During the combustion of jet engines, carbon dioxide will still be released into the atmosphere, even though the lifecycle carbon emissions of SAF are significantly lower. At the same time, air pollutants such as nitrogen oxides, sulfur oxides, carbon monoxide, and particulate matter will still be emitted, impacting air quality.

    Global Trends

    Despite slow adoption, multiple countries have implemented rules requiring aviation fuel suppliers to increase blending of SAF with conventional aviation fuel. For example, the United Kingdom introduced a SAF Mandate earlier this year. The requirement will increase linearly, from 2% in 2025 to 10% in 2030 and 22% in 2040. In the European Union, the ReFuelEU Aviation measure requires a share of SAF in EU airports from this year, which will gradually increase to 70% by 2050. Both mandates have excluded crop and virgin oil-based feedstocks to avoid deforestation, land use changes, and biodiversity loss.

    Brazil, the host country of this year’s UN climate change summit, COP30, launched the Belém Commitment for Sustainable Fuels. Announced last week, the initiative aims to quadruple the production and use of sustainable fuels in aviation by 2035. The proposal has won the support from India, Italy, and Japan, and it will be presented at the climate conference in Belém next month.

    Scaling Up SAF in Hong Kong

    Although Hong Kong does not require airlines to use SAF, Hong Kong-based airline Cathay Pacific has already implemented Asia’s first major SAF program. Launched in 2022, it commits the company to incorporate SAF for 10% of its total fuel consumption by the end of the decade. On October 21, the airline announced a joint investment agreement with Airbus, committing to co-invest up to US$70 million to support the SAF development in Asia and globally.

    Under the terms of the partnership, the two companies will work to identify,”evaluate and invest in projects that support the scaling of SAF production towards 2030 and beyond. Projects will be assessed based on their commercial viability, technological maturity, and potential for long-term offtake,” a press release read.

    Among the Cathay Pacific SAF program’s partners is Hong Kong’s Airport Authority (AAHK). Its General Manager for Sustainability, Peter Lee, said: “We recognise that SAF is a key solution to decarbonise the aviation sector, and aim to drive uptake at Hong Kong International Airport in the coming years.”

    As an international logistics hub, the Hong Kong International Airport has been the world’s busiest international cargo airport since 2010. In 2024, it handled about five million tonnes of cargo and 54.9 million passengers. With such a high flow, it is crucial to develop SAF policy and facilities to demonstrate Hong Kong’s commitment to achieving carbon neutrality and enhancing its global competitiveness and reputation.

    Speaking at a conference last October, Cathay’s General Manager of Sustainability Grace Cheung called for more government pressure for Hong Kong’s aviation sector to meet its climate goals.

    “Regulators have a key role to play for a level playing field, so that every [player] is doing the right thing for society,” Cheung said, according to the South China Morning Post. “If we leave it to the market, every company will wait for their competitors to make the first move.”

    As Hong Kong plans to develop a SAF industry chain and build a SAF blending facility, the production technology will improve and become more cost-effective in the long run. When that happens, airlines will have more incentive to use SAF.

  • Japan September exports rebound, after four straight months of declines

    Japan September exports rebound, after four straight months of declines

    YOKOHAMA, KANAGAWA, JAPAN – 2025/08/28: A loaded container ship is docked inside Tokyo Bay.

    Japanese exports in September snapped four months of declines, climbing 4.2% year on year, as shipments to Asia saw robust growth, partially offsetting the drop in exports to the U.S.

    Exports, however, missed expectations of a 4.6% rise, according to median estimates in a Reuters poll of economists.

    Shipments to Asia climbed 9.2% compared to the same period last year, while exports to the U.S., Japan’s second largest trading partner, dropped 13.3%. Exports to mainland China, Japan’s largest trading partner rose 5.8%.

    Japan’s exports had fallen into negative territory as the country grappled with U.S. tariffs with its shipments of automobiles to the world’s largest economy taking a huge hit.

    Auto shipments to the U.S. dropped 24.2% in September in terms of value, a softer fall compared to the 28.4% drop in August.

    The world’s fourth-largest economy saw imports increase 3.3% year on year, reversing course from the 5.2% decline in August and beating the 0.6% growth expected by the Reuters poll.

    Tokyo in July clinched a trade deal with Washington, bringing down tariffs on its exports to the U.S. to 15% from the 25% initially proposed by President Donald Trump.

    The data comes a day after the country got its first female prime minister in Sanae Takaichi, after months of political turmoil following electoral losses of the ruling Liberal Democratic Party under former Prime Minister Shigeru Ishiba.

    Takaichi’s stance of a loose momentary policy and massive fiscal stimulus is likely to weaken the yen, making Japan’s exports more competitive and benefiting exporters — heavyweights on the benchmark Nikkei 225 that hit a record high on Tuesday.

    Markets have priced in the so-called “Takaichi trade” since she took the helm of the LDP in September, which has seen the Nikkei rise to record highs and the yen weakening past the 150 mark.

    However, the country’s economy has held up better than expected, with the second-quarter GDP being revised upward to 0.5% quarter on quarter from 0.3% estimated initially.

    Asia-Pacific markets fell Wednesday as investors assessed trade data from Japan and its new government.

    Japanese exports in September snapped four months of declines, climbing 4.2% year on year, as shipments to Asia saw robust growth, partially offsetting the drop in exports to the U.S.

    Exports, however, missed analysts’ expectations of a 4.6% rise, according to median estimates in a Reuters poll of economists.

    Prime Minister Sanae Takaichi and her new cabinet were sworn in on Tuesday, with her former rival in the ruling Liberal Democratic Party’s leadership race, Shinjiro Koizumi, named defense minister and Satsuki Katayama becoming Japan’s first female finance minister.

    Japan’s Nikkei 225 was down 1.26%, leading losses in Asia, while the Topix index lost 0.18%. Shares of SoftBank plunged over 10%, building on their 0.26% drop on Tuesday. Shares had gained 8.5% on Monday.

    On Tuesday, the Nikkei briefly set a new intraday record of 49,945.95, before retreating after Takaichi won the parliamentary vote to become Prime Minister.

    South Korea’s Kospi index was down 0.26%, while the small-cap Kosdaq fell 0.25%. Shares of LG Chem soared as much as 10% after Palliser Capital urged the chemicals company to revamp its board and buy back shares, according to a Reuters report.

    Australia’s S&P/ASX 200 started the day down 0.73%, pulling back from earlier gains on Tuesday after rare earth stocks briefly rallied on news of a U.S.-Australia critical minerals agreement.

    Hong Kong Hang Seng index futures were at 25,919, lower than the last close of 26,027.55.

    Overnight in the U.S., the Dow Jones Industrial Average set a new closing record, boosted by strong earnings reports from companies such as Coca-Cola and 3M, while the S&P 500 was relatively unchanged.

    The 30-stock index gained 0.47% to close at 46,924.74, and briefly topped 47,000 during the session.

    The broad market S&P 500 closed just above the flatline at 6,735.35, while the tech-heavy Nasdaq Composite lagged, falling 0.16% to 22,953.67.

  • Why supermarket prices really became sky high in the UK

    Why supermarket prices really became sky high in the UK

    There has been more than a bitter twang in the glasses at British breakfast tables. Only five years ago, a typical supermarket own-label carton of orange juice could be bought for 76p for 1 litre. It now costs £1.79.

    That’s a rise of 134% since 2020, and it’s up 29% just in the past year.

    In cafes and restaurants it’s a similar story – with £3.50 to £4 now a standard price point for a glass of basic OJ.

    One colleague was outraged to be sent a bill for £9 for a glass of hangover-busting orange juice and lemonade at an unassuming little restaurant in Kent. Asked why so much, she was told that the orange juice – albeit freshly squeezed – accounted for £5.30 of the price.

    Yet as costs have surged, the taste is changing too, with certain manufacturers substituting oranges for mandarins to cut costs.

    The public is, if you like, being freshly squeezed.

    A chart showing how some orange juice prices have increased. For example, in October 2020 an own label ambient smooth juice was £0.76 and in October 2025 was £1.79 - marking a 134% increase

    There are all sorts of reasons for this: disease among crops, extreme weather, over-reliance on supply from a single nation, new rules for packaging and complexities around trade wars and Brexit.

    All of this is compounded by grocery price inflation which, after hitting 17.5% in 2023, came down (to around 5.7% in August) but is rising once again. New figures for overall inflation will be released later today.

    It is a perfect storm.

    Yet the problem is not isolated to orange juice – track the prices of all sorts of other groceries in supermarket aisles and you’ll see a similar pattern. And so understanding what has happened to orange juice offers a glimpse into how our overall grocery bills suddenly seem so expensive.

    It all prompts the question: is this storm a passing one, or are prices set to remain stubbornly high – and should brace for them staying that way permanently?

    The Bing Crosby effect

    Where else to start but in the orange groves of Florida where the industrialisation of OJ began as an initiative of the US Army during World War Two.

    The US government was seeking a source of transportable Vitamin C for troops that didn’t taste like turpentine.

    Orange juice from concentrate was commercialised by Minute Maid

    Orange juice is nearly 90% water. So gently evaporating the water off the juice and freezing the concentrate, allowed for transportability of a much better tasting product when water was later re-added.

    WW2 ended before the troops got to try it, but it ended up being commercialised by what became the American soft drink giant, Minute Maid.

    It was popularised by Bing Crosby, who, as a significant shareholder, would sing in ads and radio show jingles about frozen orange juice being “better for your health”.

    Western consumption of orange juice surged.

    Minute Maid orange juice was popularised by Bing Crosby

    Flash forward to today and an estimated 2.5 billion gallons of orange juice are drunk each year – with about a tenth of that in the UK, where the market is still growing.

    Drought, disease and flooding

    At an industrial unit in the Essex town of Basildon, green steel drums of frozen orange concentrate arrive from Brazil, overseen by Maxim McDonald.

    His firm Gerald McDonald and Co is named after his grandfather, a pioneer who was importing orange concentrate as far back as the 1940s from what was then British-mandate Palestine.

    Today it produces juices and blends them, then sells them to supermarkets and restaurant suppliers.

    But prices reached extraordinary heights in global markets, rising from $1(75p) to $1.50 (£1.12) per lb over the last decade, to a record $5.30 per lb by the end of last year.

    This followed five years of poor crops, owing to severe drought and a disease called citrus greening (caused by a bacteria spread by insects). Brazil had its worst crop since 1988. In some parts of its citrus belt, two thirds of orange trees are affected.

    “Around September of last year the price shot up to crazy levels,” Maxim tells me. “At the worst time I was being offered $7 a kilo.

    “For such a major commodity to go from $2 to $7 is insane, but it took a while to filter through to consumers.”

    Until 2023 the rise in orange juice prices was disguised among food inflation in general, explains Philip Coverdale, an industry expert at consultancy firm GlobalData.

    Producers have tried to look beyond South America but it’s not easy – the supply of oranges has been sown up by Brazil, even more so than, say, the Saudis have cornered the market for crude oil.

    Morocco, Egypt and South Africa grow oranges too but their supplies are more limited. Spain also grows them, but Valencia and Seville oranges are mostly exported as fruit, rather than concentrate. (Plus Spain too suffered from weather-related production slumps, including the floods in Valencia last October.)

    Even within Brazil the market is concentrated in the hands of huge industrialised conglomerates.

    In a truly competitive market the price would settle again – but it hasn’t, nor does the industry expect it to. This is a phenomenon that is common to many other ordinary groceries too whose prices have risen.

    Oranges becoming less sweet

    Florida is the other traditional exporter of oranges, but output from the Sunshine State over the past year has been the lowest since the Great Depression, amid a high number of hurricanes and long-term problems caused by citrus greening.

    One problem with greening is that it reduces sugar content, making oranges less sweet.

    “Not many are buying Florida oranges any more unless it is a requirement to label the juice ‘Florida Orange’,” says Maxim McDonald.

    “It’s very difficult to get oranges out of Florida [because of the shortages] and it’s too expensive.”

    Spain also grows oranges – but Valencia and Seville oranges are mostly exported as fruit, rather than concentrate

    One of the leading suppliers to Tropicana sold off some of its land earlier this year to build homes.

    Tropicana itself, the marquee US brand for orange juice, had to restructure its debts this year. Pepsi has also sold most of its stake in it.

    One of Tropicana’s recent product innovations in the US has been to launch an “essentials” brand of orange juice “blends” – combining orange, apple and pear juice – at a lower price.

    Similar trends can be seen on British shelves. Orange is being mixed with mango, mandarins and clementine juice. Mango purée is especially cheap right now, driven by a good harvest in India. Mandarin concentrate, meanwhile, is cheaper than its orange equivalent because there is less demand for it.

    These developments save money, but also maintain the traditional sweetness of the taste.

    Tariffs: War on the orange

    Then there is the added impact of the recent spike in trade tensions with the US since President Trump introduced new tariffs.

    Oranges, it transpires, have been at the centre of it.

    US exports of orange juice to Canada have slumped to a 20-year low after Canada put counter-tariffs on US exports. The former PM Justin Trudeau warned that Canadians might have to “forgo Florida orange juice”.

    The Trump administration has also settled on a 10% tariff on orange juice coming from Brazil, which will feed into US supermarket prices.

    In 2024, the UK eliminated tariffs on some imports produced from fruit grown outside Britain. But tariffs on certain sweeter, cheaper varieties and blends were not part of this.

    And while the tariff cuts might have helped, they were vastly outweighed by the increase in the underlying price.

    Then there are new regulations around packaging, further adding to the pressures.

    The rules, known as Extended Producer Responsibility, are aimed at improving recycling rates, with a weight-based fee. All juice producers will be impacted, especially those still using glass bottles.

    In August a Bank of England report said that high food price inflation is driven partly – and among other things – by these regulations.

    Did the West fall out of love with OJ?

    In Brazil, the orange harvest has recovered somewhat – this is the greatest hope for a return to normal prices. Yet it coincides with sinking demand: global consumption of orange juice is now down 30% from a peak two decades ago.

    Though this may be partly down to the high prices, in certain parts of the world there has also been a shift in perception about the sugar content and health benefits or otherwise of fruit juice.

    “When young children are not regularly given juice from an early age, they are less likely to be regular juice drinkers in later years,” suggests Philip Coverdale at GlobalData.

    Demand is increasing in countries with growing middle classes, such as China, South Africa, and India. But elsewhere other more exotic fruit juices such as mango, pear and pomegranate are growing in popularity.

    South Africa grows oranges but its supplies are small

    Ultimately, however, orange juice is a staple that supermarkets have long been used to selling at low prices. And the price spikes to £2 a carton could, with for example better weather, simply reverse.

    “The volatility in the harvest appears to have reduced,” says Giles Hurley, UK CEO of Aldi, “Our buying team are doing everything they can to ensure that that saving is passed on to consumers.”

    Others in the supply chain are less convinced, given that much of the frozen concentrate was bought at last year’s high prices. Plus, the stranglehold of the small number of giant producers who control the market remains.

    As for the citrus greening, some major commercial producers, including Coca-Cola, which owns Minute Maid and Innocent, have contributed to a project to Save the Orange, using artificial intelligence to find a way to combat it.

    It’s a long-term project – and even if fruitful, it may be some time before the effect – if at all – filters through to grocery bills.

    But the story of orange prices does also show how an upward price shock gets transmitted around the world far more quickly than a downward one.

    Chocolate, coffee, butter and beef

    Oranges are not the only food that has seen a price spike, of course. The price of beef and veal is up almost 25% in a year. Butter is up almost 19%, and chocolate and coffee 15% and milk over 12%, all according to the Office for National Statistics.

    This all suggests that, more generally, there may be something else at play. And that for all the food and drink spikes, the consumer was actually protected from the worst of it for a period – and now it is pay back time.

    “It might be the retailers didn’t full pass through the cost increase in the first place and therefore it’s a way of recouping some of the margin they would otherwise have got,” says Steve McCorriston, Professor of Agricultural Economics at the University of Exeter.

    Do consumers need to simply accept the fact that the UK will be increasingly exposed to food price shocks?

    Ultimately, though, trying to unpick the precise reason for why our food and drink costs what it does is very difficult – other factors that influence price can go undetected.

    “What we don’t know much about is how these supply chains tend to work in practice. It’s difficult to uncover relationships between retailers and manufacturers or farmers and the use of contracts.”

    There is also a broader question that goes well beyond orange juice: do consumers in the UK need to simply accept the fact that as a densely populated small country with limited agriculture, a changing climate means the UK will be increasingly exposed to food price shocks?

    A 2024 government report on food security noted: “The UK continues to be highly dependent on imports to meet consumer demand for fruit, vegetables and seafood…

    “Many of the countries the UK imports these foods from are subject to their own climate-related challenges and sustainability risks.”

    And so it could be that this is only the start of a wild ride on what we pay for our food and drink.
