UK aviation industry vows net zero carbon by 2050

0 71

The UK’s aviation industry is promising to reduce its net carbon emissions to zero by 2050.

Cleaner engines, new fuels and planting trees will all help, according to the industry group Sustainable Aviation.

The plan will mean airlines can cut pollution even as passenger numbers grow by an expected 70%, it said.

But campaigners say the only way to cut airline pollution is by reducing air travel and cancelling new airports and runways.

“We need to restrict flying,” said Muna Suleiman, from Friends of the Earth. “We can’t have airport expansion at the same time.”

Rail travel and buses are greener alternatives and taxes should be applied to frequent fliers, she said.

Biofuels, which Sustainable Aviation say will be part of the industry’s plan, still pollute, Ms Suleiman added. “The crisis is here and now.”

The aviation sector is under increasing pressure to come up with a plan to cut emissions, especially as it has no commercial comparator yet to the electric car, which is seen as the auto industry’s hope for cutting emissions.

While other forms of transport produce more carbon, individual journeys on planes produce large amounts of CO2.

Sustainable Aviation says the UK industry can reduce its emissions of CO2 from 30 million tonnes a year to zero, without restricting growth

An economy-class return flight from London to New York emits an estimated 0.67 tonnes of CO2 per passenger, according to the calculator from the UN’s civil aviation body, the International Civil Aviation Organization (ICAO).

That is equivalent to 11% of the average annual emissions for someone in the UK or about the same as all of those caused by someone living in Ghana over a year.

US firm Wright Electric said last week it has started electric engine development for a 186-seater plane, and hopes to begin test flights in 2023.

British Airways is investing in a project to make fuel from rubbish.

‘Difficult sector’
“We are going to have to do this through many projects,” Alex Cruz, chief executive of British Airways, told the BBC.

“Biofuels will give us a greener alternative and we are attracted by that,” he said, while conceding that they will still produce carbon dioxide and that they are expensive today.

“We do believe we will reach a point where the price will be compatible with the rest of fuel prices.”

BA will also retire old planes, with the double-decker Boeing 747 being phased out in 2024.

Other plans include planting trees – so-called carbon offsetting – and investing in renewable power sources, said Matt Gorman, a council member of Sustainable Aviation.

“Aviation is one of the more difficult sectors to decarbonise but we are absolutely confident it can be done,” said Mr Gorman. “We have to do it”

Sustainable Aviation’s members include Heathrow Airport, British Airways, easyJet, Rolls Royce, Airbus and air traffic controller Nats.
