A more eco-friendly blend of aviation fuels could help reduce the impact of air travel on climate warming by producing less of a vapour trail, according to a new study.
The findings suggest that contrails from aircraft using a sustainable blend of fuels could contain 50 to 70 per cent less soot and ice particles compared with conventional fuels, according to a paper published in the journal Communications Earth & Environment.
Contrails – a combination of ice crystals and soot - contribute to global warming by trapping infrared radiation from the Earth’s surface in the atmosphere. This form of global warming is thought to be more harmful than an aircraft’s emissions.
Climate experts have warned of a significant increase in contrail-linked effects by 2050 because of a likely increase in air traffic.
Experts have considered other measures including changing the cruising altitudes of planes and altering routes to avoid weather that is more likely to create contrails. But those measure could lead to more fuel being used and longer flights.
Researchers from Germany and the US examined whether the make-up of aviation fuels could reduce the climate-warming qualities of contrails.
They compared soot and ice crystals in the contrails behind an Airbus A320 using five different products, from standard jet fuel to ones using more synthetic or biofuels that produce fewer of the sooty particles that cause the contrails.
The traditional fuels contained "aromatic compounds" that led to more soot. The researchers found that when aircraft burnt the sustainable fuels, they led to fewer but larger ice crystals that warmed the atmosphere less.
“Meaningful reductions in aviation’s climate impact could therefore be obtained from the widespread adaptation of low aromatic fuels, and from regulations to lower the maximum aromatic fuel content,” the study found.

Libya's Gold
UN Panel of Experts found regime secretly sold a fifth of the country's gold reserves.
The panel’s 2017 report followed a trail to West Africa where large sums of cash and gold were hidden by Abdullah Al Senussi, Qaddafi’s former intelligence chief, in 2011.
Cases filled with cash that was said to amount to $560m in 100 dollar notes, that was kept by a group of Libyans in Ouagadougou, Burkina Faso.
A second stash was said to have been held in Accra, Ghana, inside boxes at the local offices of an international human rights organisation based in France.

FFP EXPLAINED
What is Financial Fair Play?
Introduced in 2011 by Uefa, European football’s governing body, it demands that clubs live within their means. Chiefly, spend within their income and not make substantial losses.
What the rules dictate?
The second phase of its implementation limits losses to €30 million (Dh136m) over three seasons. Extra expenditure is permitted for investment in sustainable areas (youth academies, stadium development, etc). Money provided by owners is not viewed as income. Revenue from “related parties” to those owners is assessed by Uefa's “financial control body” to be sure it is a fair value, or in line with market prices.
What are the penalties?
There are a number of punishments, including fines, a loss of prize money or having to reduce squad size for European competition – as happened to PSG in 2014. There is even the threat of a competition ban, which could in theory lead to PSG’s suspension from the Uefa Champions League.
