Airlines' climate goals at risk as support for fossil fuels grows
The aviation industry is under increasing pressure to reduce its environmental impact. Air travel accounts for about 2.5 to 3 percent of global carbon emissions, and while airlines are investing in cleaner technology, their main hope lies in using more Sustainable Aviation Fuel (SAF).
The airline industry's plan to reach net-zero carbon emissions by 2050 is under threat due to a global shift towards fossil fuel-friendly policies, according to a major aviation group.
Speaking at an annual industry meeting in India on Sunday, the International Air Transport Association (IATA) warned that climate progress could slow down significantly. Marie Owens Thomsen, IATA's top sustainability official, pointed to leaders like U.S. President Donald Trump, whose policies promote oil and gas over renewable energy.
'The return of leaders who support fossil fuels and roll back climate regulations is clearly a setback,' said Owens Thomsen. 'It puts the 2050 goal in danger.'
Even so, she believes the industry will continue to move towards greener practices, just more slowly. 'It's not going to stop us, but it will delay progress,' she added.
The aviation industry is under increasing pressure to reduce its environmental impact. Air travel accounts for about 2.5 to 3 percent of global carbon emissions, and while airlines are investing in cleaner technology, their main hope lies in using more Sustainable Aviation Fuel (SAF).
SAF is a type of fuel made from renewable sources like used cooking oil and animal fats. It emits significantly less carbon than traditional jet fuel, but it comes at a steep cost—three to four times more expensive than conventional fuel.
Efforts are being made to increase SAF use. In the European Union, airlines are now required to include at least two percent SAF in their fuel mix. That number is set to rise to six percent by 2030 and 70 percent by 2050.
Still, current production levels are far below what's needed. IATA estimates that global SAF production will reach 2.5 billion litres in 2025 — double last year's output, but only about 0.7 percent of what the industry uses in total.
President Trump's administration, now in its second term, has shifted away from supporting clean aviation fuels. Under former President Joe Biden, U.S. policies had offered strong incentives for SAF development through tax credits and government funding. Trump's renewed focus on oil and gas marks a reversal, creating uncertainty for airlines and fuel producers alike.
The UN's International Civil Aviation Organization (ICAO) set the 2050 net-zero target, with broad global support. But if political winds continue to shift away from climate action, experts fear the goal may no longer be realistic.
IATA says it will continue pushing for progress, even in a tougher political environment. 'This is a long-term challenge,' said Director General Willie Walsh. 'We can't afford to slow down — but right now, that's exactly what's happening.'

Words on wealth: the importance of financial regulation in protecting consumers
This article explores the critical role of financial regulation in protecting consumers from exploitation and ensuring fair market practices, highlighting recent challenges faced by regulatory bodies. Image: Ayanda Ndamane / Independent Newspapers. It shocked me to learn that the Trump administration in the United States, with the assistance of Elon Musk and his Department of Government Efficiency, had dismembered and severely impeded the function of the Consumer Financial Protection Bureau (CFPB). This US government agency was established in 2011 under President Barack Obama in the aftermath of the global financial crisis of 2008. According to the US Treasury Department, the bureau is tasked with the responsibility to 'promote fairness and transparency for mortgages, credit cards, and other consumer financial products and services'. On its website, the CFPB says its central mission 'is to make markets for consumer financial products and services work for Americans – whether they are applying for a mortgage, choosing among credit cards, or using any number of other consumer financial products'. Wikipedia notes that many thousands of consumer complaints about financial services providers, including banks and credit card issuers, have been received and attended to by the CFPB. The CFPB is not the only US agency acting against unfair practices by financial services providers; there is the longer-running and more established Federal Trade Commission (FTC), which has wide-ranging powers across business sectors that include enforcing antitrust laws. This has also been targeted by President Trump, who in March fired two of the FTC's Democratic commissioners, although the legitimacy of those firings is now being questioned in court. Which brings me to the topic of financial regulation generally. Force for good I strongly believe that regulation that levels the playing field, protects consumers from exploitation, and enables them to make better financial decisions is good for society as a whole, including the industry it regulates. Advocates of free markets would argue that companies in a competitive environment are self-regulating. I disagree. Competition is a powerful and vital force, but its nature is such that you will always have someone trying to make a quick buck by pushing the boundaries of what is normal or ethical. This is a big enough problem in a regulated environment; imagine how bad it would be in an unregulated one. Video Player is loading.

Next Stay Close ✕ A supreme example of pushing the boundaries is, of course, in sport - specifically those sporting codes that primarily test physical prowess, such as athletics, swimming, weight-lifting, and cycling. Before these sports became commercialised, there was little monetary incentive for athletes to cheat. Perhaps a small amount of cheating went on behind the scenes, but public perception was that the winners represented the pinnacle of human strength, speed, and endurance, and the sports codes were popular because people believed the competition was real and the winners genuine. That's not the case anymore. When I watch an athlete win a race, there's always the nagging question in the back of my mind: did he or she win on natural ability, or did performance-enhancing drugs contribute to the win? In which case, why am I wasting my time watching someone cheat? It started with a couple of risk-takers pushing the boundaries. Eventually, just to remain competitive, everyone was doping, inventing more and more elaborate schemes to evade detection. Moving targets Regulators typically struggle to keep up with the novel ways people find to push the boundaries. I like to think that the financial regulators have had more success than the sports regulators. In financial circles, there's a recent push by those on the fringes to market private equity investments, which invest in private, rather than publicly listed, companies. I have nothing against seasoned, wealthy investors putting their money into private ventures – they know the risks. I do have a problem when private equity investments are marketed to consumers who are not aware of the risks. There are currently at least two companies I know of that are marketing private equity products, including a living annuity, to the public, making out as if they are just regular products. Well, they are not regular. They carry a far higher risk for the investor than publicly listed equity. Pension funds, which have substantial assets and expertise behind them, are restricted by law to invest no more than 15% of their portfolio in private equity. And yet these fringe providers are asking consumers to trust them with their life savings.

Trump says he has no plans to speak to Musk as feud persists
US President Donald Trump said on Friday he has no plans to speak with Elon Musk, signalling the president and his former ally might not resolve their feud over a sweeping tax-cut bill any time soon. Addressing reporters aboard Air Force One, Trump said he wasn't 'thinking about' the Tesla CEO. 'I hope he does well with Tesla,' Trump said. However, Trump said a review of Musk's extensive contracts with the federal government was in order. 'We'll take look at everything,' the president said. 'It's a lot of money.' Trump may get rid of the red Tesla Model S that he bought in March after showcasing Musk's electric cars on the White House lawn, a White House official said, speaking on condition of anonymity. Musk, for his part, did not directly address Trump but kept up his criticism of the massive Republican tax and spending bill that contains much of Trump's domestic agenda.

Iran says US travel ban shows 'deep hostility' for Iranians, Muslims
Iran on Saturday blasted US President Donald Trump's travel ban on countries including the Islamic Republic, saying it showed 'deep hostility' towards Iranians and Muslims. 'The decision to ban the entry of Iranian nationals — merely due to their religion and nationality — not only indicates the deep hostility of American decisionmakers towards the Iranian people and Muslims but also violates ... international law,' a senior foreign ministry official said in a ministry statement posted on the X social media platform. Trump's proclamation on Wednesday will bar citizens from 12 countries starting on Monday at 12:01am . The countries are Afghanistan, Myanmar, Chad, Congo Republic, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan and Yemen. The ban, which Trump said was necessary to protect against 'foreign terrorists', was reminiscent of a similar move he implemented during his first term in office from 2017 to 2021, when he barred travellers from seven Muslim-majority nations.
