Making just TWO PER CENT of flights travel 2,000ft higher or lower than normal altitude could slash the climate impact of aeroplane contrails by almost 60 per cent

  • Majority of troublesome plane-induced clouds are caused by just 2.2%of flights
  • These are formed when contrails merge and spread into cirrus natural clouds 
  • Making 1.7% of flights travel 2,000 feet higher or lower limits contrail formation 
  • This in turn stops unique clouds from forming and reduces warming affect of contrails by 59.3% 

Forcing a tiny percentage of flights to change their cruising altitude by 2,000ft could slash the climate impact of plane contrails by almost 60 per cent, a study reveals. 

Research into contrails – the white streams that billow out behind planes and criss-cross the sky – can form clouds which are just as harmful to the environment as carbon dioxide emissions. 

The vast majority of these troublesome plane-induced clouds are caused by just 2.2 per cent of flights. 

Researchers found that making 1.7 per cent of aircraft fly 2,000 feet higher or lower than…
