Flying planes consistently higher or lower than current altitudes could help the aviation industry reach net zero faster, a report has found.
The suggestion is among four goals the industry could adopt to help the sector – a major contributor to climate change – achieve net-zero emissions globally by 2050.
“Aviation stands at a pivotal moment, much like the automotive industry in the late 2000s,” said Prof Rob Miller, director of the Whittle Laboratory at the University of Cambridge. “Back then, discussions centred around biofuels as the replacement for petrol and diesel – until Tesla revolutionised the future with electric vehicles. Our five-year plan is designed to accelerate this decision point in aviation, setting it on a path to achieve net zero by 2050.”
The plan, drawn up alongside the Cambridge Institute for Sustainability Leadership, outlines four steps the researchers say must start immediately and be completed within five years for the sector to remain on track to achieve net zero by 2050.
Eliminating vapour trails – a combination of ice crystals and soot that can follow an aircraft’s path – is the first. About one in 30 flights produces a persistent contrail, which can trap heat and increase aviation’s climate impact.
“Persistent contrails can be avoided by adjusting an aircraft’s altitude in regions where contrails form, known as ice-supersaturated regions. These regions are pancake-shaped – wide but shallow – making altitude changes effective in preventing contrail formation,” the report said.
“Successfully implementing contrail avoidance could reduce the climate impact of aviation by roughly 40 per cent.”
Commercial planes typically fly at an altitude of 31,000 to 42,000 feet.
The second goal is to introduce new policies aimed at achieving efficiency across the existing aviation sector, such as reducing fuel burn by using new aircraft and engine technology.
“However, several bold efficiency measures exist, which are currently hard to access because they involve systems-wide change,” the report said. “If implemented, these measures could reduce fuel burn by up to 50 per cent by 2050.”
Under the third goal, governments would reform sustainable aviation fuel policies, moving beyond purely biomass-based methods to introduce more carbon-efficient synthetic production techniques.
The last of the four goals is to launch 'moon shot' technology demonstration programmes to assess the benefits of transformative technology.
The industry is primarily relying on sustainable aviation fuels to help it reach net zero. But other options should be studied, including long-haul hydrogen aircraft, which would be lighter and remove CO2 emissions from flight, the report said.
“If these goals are not immediately implemented and achieved by 2030, the window for transformation will close, leaving the world to face the escalating climate consequences of a rapidly expanding aviation industry, which is projected to at least double by 2050,” it added. “The urgency of this moment cannot be overstated.”

Key findings of Jenkins report
- Founder of the Muslim Brotherhood, Hassan al Banna, "accepted the political utility of violence"
- Views of key Muslim Brotherhood ideologue, Sayyid Qutb, have “consistently been understood” as permitting “the use of extreme violence in the pursuit of the perfect Islamic society” and “never been institutionally disowned” by the movement.
- Muslim Brotherhood at all levels has repeatedly defended Hamas attacks against Israel, including the use of suicide bombers and the killing of civilians.
- Laying out the report in the House of Commons, David Cameron told MPs: "The main findings of the review support the conclusion that membership of, association with, or influence by the Muslim Brotherhood should be considered as a possible indicator of extremism."

So what is Spicy Chickenjoy?
Just as McDonald’s has the Big Mac, Jollibee has Spicy Chickenjoy – a piece of fried chicken that’s crispy and spicy on the outside and comes with a side of spaghetti, all covered in tomato sauce and topped with sausage slices and ground beef. It sounds like a recipe that a child would come up with, but perhaps that’s the point – a flavourbomb combination of cheap comfort foods. Chickenjoy is Jollibee’s best-selling product in every country in which it has a presence.
Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”
