UK government and Google test flight path adjustments to reduce aviation contrails

The British government and Google have launched a 30-month research program, Operation Blue Skies, to test whether minor altitude adjustments for commercial flights can reduce the formation of heat-trapping contrails. During the next two winters, air traffic controllers will direct select flights in the North Atlantic to deviate up to 2,000 feet to avoid areas where contrails are likely to form.

Why It Matters

This trial aims to determine if adjusting flight altitudes across an entire air corridor can significantly lower the climate impact of aviation, which currently accounts for 1% to 2% of global warming due to contrail formation.

Key Facts

  • The UK government is funding over half of the 5 million pound ($6.76 million) research program.
  • The trial, Operation Blue Skies, will take place over the next two winters in the Shanwick Oceanic Control Area.
  • Air traffic controllers will direct flights to deviate up to 2,000 feet (610 meters) in altitude to avoid contrail formation.
  • There will be approximately 20 to 40 test days per winter.
  • Researchers expect about 10,000 flights to pass through the area during the testing period.
  • Hundreds of flights are expected to deviate their routes during the trial.
  • Contrails are estimated to be responsible for 1% to 2% of global warming.
  • The Shanwick airspace accounts for approximately 5% of total global contrail contribution.
  • The consortium includes Google, the UK Department for Transport, the Met Office, NATS, Contrails.org, Imperial College London, and the University of Cambridge.
