Heathrow could get sonic boom ‘every five minutes’ from fast jets

Supersonic aircraft would bring noise and greater CO2 emissions, report says

Heathrow airport could be hit by a sonic boom every five minutes as a new class of supersonic aircraft come into service, research suggests.

It is predicted that by 2035 there could be demand for up to 2,000 supersonic passenger jets, which could knock hours off long-haul trips.

As well as further eroding the chance of limiting global warming by contributing to greater aviation emissions, the revival of supersonic aircraft would bring sonic booms to many parts of the UK, according to analysis by the International Council for Clean Transportation (ICCT).

Dan Rutherford, the report’s author, said there could be 300 daily landings and takeoffs by supersonic jets at Heathrow airport, and the noise would affect twice as large an area as subsonic craft. Manchester and Gatwick airports would be less affected with around 10 and 20 flights per day respectively, the report says.

Rutherford said: “Separately, the UK could be impacted by sonic boom from flights between continental EU and North America. Central England could experience sonic booms about 50 times per day, or approximately once every 20 minutes over a 16-hour flight day. In Ireland it could be much worse.”

The supersonic jets are predicted to emit as much as 2.4 gigatonnes of CO2 over their 25-year lifespan, taking up a fifth of the aviation sector’s carbon budget for this century. After the US, the UK would be the second highest greenhouse gas emitter from the new jets, the ICCT says.

Prof Kevin Anderson, of Manchester University’s Tyndall Centre for Climate Change Research, said: “Science has demonstrated the planetary-scale impacts that our deep addiction to fossil fuels is having on global ecosystems and on our own children’s futures. Yet rather than transform the world to one of low-carbon prosperity, our resources and ingenuity are being squandered on toys for a privileged few. Do we really think that the prospect of attending Davos by supersonic jet is an appropriate response to the existential threats we face?”

Negotiators from the International Civil Aviation Organisation will meet in Montreal next week to try to agree noise and emissions standards for the next generation of supersonic jets, which could take effect from 2025.
