Air New Zealand Ltd’s decision to ditch its 2030 emissions target suggests more airlines would also have to confront a harsh reality: There is simply not enough sustainable fuel or new, more efficient aircraft. This double whammy has left the world’s commercial carriers, among the planet’s biggest polluters, without their two best decarbonization weapons.
Global supply of sustainable aviation fuel (SAF) would be just 0.5 percent of total fuel requirements this year, the International Air Transport Association (IATA) said.
At the same time, Boeing Co and Airbus SE cannot make jets fast enough. Boeing, under pressure from regulators, has slowed output to improve quality. Airbus is so stretched it is even turning down orders. While next-generation jets can consume 15 to 20 percent less fuel, wait times to get them delivered are years long.

It all means airlines such as Air New Zealand have to fly older and dirtier planes for longer, while finding it almost impossible to fill them up with clean-burning fuel. The fact that SAF can be several times more expensive than conventional jet fuel does not make it any easier for carriers to hit near-term carbon targets.
Other airlines struggling to buy enough sustainable fuel might have to follow Air New Zealand’s example, said Jack Shepherd, a sustainable fuels manager at Blunomy, an energy transition consulting company.
The fallout from such decisions would extend far beyond the next decade. If more airlines scrap interim emissions goals, fuel suppliers would be even less likely to invest in SAF production, Shepherd said.
At worst, the industry’s mid-century goal of carbon neutrality also disappears from reach, he added.
“If we’re not on track in 2030, then the 2050 goal is going to be hard to achieve,” Shepherd said. “When the general public is calling for a decarbonized world, it puts pressure on these airlines and their social license to operate.”
The widespread production of SAF has been slowed by high costs, limited feedstock and patchy policy support. Much of the small volumes available are being produced in the US and Europe.
Air New Zealand had wanted to cut carbon intensity by 28.9 percent by 2030 from a 2019 baseline, and has now begun work on a new near-term target. It still aims to hit net zero by mid-century.
The Auckland-based company might be one of the first airlines to publicly abandon an interim climate goal, but rumblings about whether aviation’s targets can be hit have been getting louder.
Cathay Pacific Airways Ltd this month said that the enormity of the task had become clear, following talks with about 50 potential suppliers.
“We have really witnessed how difficult it is for the SAF industry to take off,” Cathay sustainability general manager Grace Cheung said in an interview.
Even the industry’s 2050 net zero targets were unattainable, then-Qatar Airways CEO Akbar al-Baker said last year.
SAF, made from waste fats or agricultural feedstock, could cut emissions by almost 80 percent if it fully replaces jet kerosene, airlines said. They are betting their sustainable future on SAF, because other fuel sources such as hydrogen or electric batteries remain far from commercialization.
However, even with aviation’s commitment to SAF, IATA in June cut its estimates for total SAF production in 2030 after finding that many projects were behind schedule.
Output had to increase by a factor of 1,000 by 2050, said IATA, which represents more than 300 airlines worldwide.
Yet IATA said such a rate of increase sounded almost implausible.
The Science-Based Targets initiative, the world’s top arbiter of corporate climate goals, does not include many of the biggest airlines on its list of companies with verified net zero targets.
Airlines including International Airlines Group, owner of Iberia, Japan Airlines and British Airways, longer make the cut.
Meanwhile, decarbonizing air travel is becoming an even larger job.
Emissions from aviation are forecast to rise 82 percent by 2050 under BloombergNEF’s base case Economic Transition Scenario, which assumes nations and companies rely on technologies that are currently economic. That would see the industry’s share of global carbon dioxide pollution jump to from about 2.7 percent today to about 6.7 percent.
When it comes to cutting emissions, it is time for airlines to acknowledge the limits of what is possible, Emirates president Tim Clark said.
“We’ve got to have a grown-up conversation about what is achievable,” Clark said in an interview at the Farnborough Air Show this month. “We shouldn’t give up on it. We should just inject a sanity check.”

The return of US president-elect Donald Trump to the White House has injected a new wave of anxiety across the Taiwan Strait. For Taiwan, an island whose very survival depends on the delicate and strategic support from the US, Trump’s election victory raises a cascade of questions and fears about what lies ahead. His approach to international relations — grounded in transactional and unpredictable policies — poses unique risks to Taiwan’s stability, economic prosperity and geopolitical standing. Trump’s first term left a complicated legacy in the region. On the one hand, his administration ramped up arms sales to Taiwan and sanctioned
The Taiwanese have proven to be resilient in the face of disasters and they have resisted continuing attempts to subordinate Taiwan to the People’s Republic of China (PRC). Nonetheless, the Taiwanese can and should do more to become even more resilient and to be better prepared for resistance should the Chinese Communist Party (CCP) try to annex Taiwan. President William Lai (賴清德) argues that the Taiwanese should determine their own fate. This position continues the Democratic Progressive Party’s (DPP) tradition of opposing the CCP’s annexation of Taiwan. Lai challenges the CCP’s narrative by stating that Taiwan is not subordinate to the
World leaders are preparing themselves for a second Donald Trump presidency. Some leaders know more or less where he stands: Ukrainian President Volodymyr Zelenskiy knows that a difficult negotiation process is about to be forced on his country, and the leaders of NATO countries would be well aware of being complacent about US military support with Trump in power. Israeli Prime Minister Benjamin Netanyahu would likely be feeling relief as the constraints placed on him by the US President Joe Biden administration would finally be released. However, for President William Lai (賴清德) the calculation is not simple. Trump has surrounded himself
US president-elect Donald Trump is to return to the White House in January, but his second term would surely be different from the first. His Cabinet would not include former US secretary of state Mike Pompeo and former US national security adviser John Bolton, both outspoken supporters of Taiwan. Trump is expected to implement a transactionalist approach to Taiwan, including measures such as demanding that Taiwan pay a high “protection fee” or requiring that Taiwan’s military spending amount to at least 10 percent of its GDP. However, if the Chinese Communist Party (CCP) invades Taiwan, it is doubtful that Trump would dispatch
