Zero-carbon aviation ‘too slow’ to meet UK climate goals

‘Denial within government over the ‘unpleasant truth’ of the need to curb demand’, summarises the Telegraph. Soundbites and targets are one thing, reality another – as usual where climate obsessives calling for ‘reduced demand’ are concerned.

‘Jet Zero’ technology will not be ready in time to meet the Government’s climate targets, a leading aerospace engineer has admitted.

Emissions from international aviation were included in national targets for the first time this week as the Government pledged to reduce greenhouse gases by 78 per cent from 1990 levels by 2035.

Its strategy relies on the development of new technology, which it is supporting through its Jet Zero council, which has the ambitious target of creating the first zero-emissions commercial flight.

But Guy Gratton, who sits on one of the Jet Zero sub committees and leads cutting-edge research into low carbon aviation at Cranfield University told the Telegraph that “the unpleasant truth” was that this would not be enough and air travel would have to be limited to meet emissions targets.

“Technology can do a lot, but I don’t think it’s going to do everything,” Mr Gratton, an associate professor of aviation and the environment, said.

He warned there was “a degree of denial” about introducing the necessary curbs on demand “because it is so politically problematic, a position to take.”

“Nobody who takes national economies seriously, wants to see a reduction in air transport,” Mr Gratton said.

He added that there is a “real problem” in reconciling protecting the national economy and tackling the emissions from air travel.

Developments in fuel efficiency already save around 2 per cent per passenger mile annually, but these are outstripped by a growth in demand of more than 5 per cent a year, giving a roughly 50 per cent emissions increase by 2040.

International aviation accounts for around 7 per cent of the UK’s overall emissions.

The Government has yet to lay out the exact reductions it plans but does not have plans to cap demand, with Boris Johnson this week saying “humanity is going to need to fly”.

That is at odds with its advisory body, the Climate Change Committee, which recommends capping demand growth, from an expected 64 per cent rise to a 25 per cent rise by 2050.

    Great! An expert tells us what everyone else already knew.

    . . . according to the cover story of April 26 issue of Time Magazine. How have we fooled ourselves into thinking that man-made climate change is the dominant cause of societal problems?
    – – –
    Or any problems at all.

    Have we reached peak governmental insanity yet?

  5. stpaulchuck says:

    will the passengers have to help wind up the rubber band or will the ground crew handle it?

    the Climate Change Committee, which recommends capping demand growth

    What would this ‘capping’ look like? They really don’t like demand for anything that smacks of people getting what they wanted.

  7. ivan says:

    The simple answer to all this climate nonsense would be for the government to repeal the Climate Change Act (2008) and all the regulations hanging off it including the CCC. That will never happen at the moment because Princess Nut Nut won’t allow it.

    I would like to see the world go into a little ice age just to show the green climate change idiots just how idiotic they are.

    Just more and more handwringing.

    So, let me get this straight:

    I can screw around with national economies and political advantage by choosing where my flight to Europe lands? Nice!

    So I think next time I’m headed that way, I’ll land in Germany. Take a train to the UK later…

  10. Phoenix44 says:

    You can’t cap demand, you can only cap supply. If my demand is not met I am poorer.

  11. oldbrew says:

    If Heathrow can’t help you, try Amsterdam Schiphol – six runways.

    ‘in 2023, Schiphol will be able to handle over 70 million passengers.’ – except when climate miserablists turn up to cause trouble? They should note ‘The entire airport is below sea level’ so they might drown 😮

    ZeroAvia Hydrogen Test Bed Crashes After Off-Airport Landing
    May 1, 2021

    ZeroAvia’s ambitious program to develop hydrogen-powered aircraft suffered a setback on April 29 when its Piper Malibu Mirage testbed was severely damaged in an off-airport landing in the U.K. The aircraft landed in a field adjacent to Cranfield Airport. The left wing was sheared off in the mishap, as was the nosegear. There was also extensive fuselage and tail damage. The aircraft appeared to have hit a hedge during the rollout. There were no injuries.

    The truth about Joe Biden’s climate summit: Unrealistic pledges revealed as grandstanding
    Date: 03/05/21 Financial Times

    Of the top 20 global CO2 emitters, not a single one is hitting its climate goals as outlined under the Paris Agreement, according to recent data from the Climate Action Tracker.
    . . .
    When Yoshihide Suga pledged to slash Japan’s carbon emissions by 2030, the prime minister received a warm welcome from world leaders at Joe Biden’s climate summit. But his announcement sparked panic across Japan’s bureaucracy.
    . . .
    In comments that were taken as emblematic of the government’s lack of planning, Shinjiro Koizumi, the environment minister, sparked criticism and social media derision when he told a television programme that the 46 per cent figure had “just floated up”.

    “just floated up” – 🤣

    ‘no analysis to confirm it is possible’ – that’s how it’s done these days, to avoid any annoying experts saying ‘impossible’.

  13. saighdear says:

    Around about now, example:Inverness to Trondheim: Car, Train, Bus, taxi to Aberdeen, fly to Schipol, land in Oslo, fly maybe direct to Trondheim…… Time and grief. LandingTaxes landing taxes, Meeting germs, meeting germs, spreading germs, spreading germs – all in the name of getting a job done. WHY?
