How Etihad intends to combat contrails while crossing the Atlantic
During an Atlantic trip, Etihad is taking efforts to prevent contrails.
As part of the continuing collaboration with SATAVIA, the national airline of the United Arab Emirates, Etihad Airways, is implementing contrail prevention on a special NetZero flight during the COP27 event.

On Sunday, November 13, the airline will fly a specially designated NetZero* flight, EY130, from Washington Dulles Airport to Abu Dhabi. This flight will demonstrate the viability of net-zero commercial aviation by utilizing sustainable aviation fuel (SAF), SATAVIA contrail prevention, and other operational efficiencies.
The flight is the most recent in Etihad’s series of Eco Flights that have been conducted over the previous two years. It comes after the EY20 Sustainable Flight that Etihad conducted from London Heathrow to Abu Dhabi last year, which reduced overall climate effect by 72%.
The trip will be the first Etihad transatlantic crossing to actively manage non-CO2 climate effects from contrail generation, confronting a sustainability challenge that accounts for up to 60% of aviation’s climate footprint. This builds on Etihad’s weekly contrail prevention exercises with SATAVIA.
In addition to enabling contrail prevention in routine aircraft operations, SATAVIA undertakes post-flight climate effect analyses for conversion into future carbon credits, with a first-ever exchange via auction scheduled with Air Carbon Exchange in December 2022.
The flight is being described as NetZero rather than ‘Carbon Neutral’ as it is achieving more than off-setting the CO2 emissions. To categorize this flight as NetZero, Etihad must demonstrate the absolute maximal direct emissions reductions operations possible. This includes (but is not limited to):
- Utilizing its Etihad Greenliner fleet – the Boeing 787 – with competitive fuel efficiency per passenger
- Maximizing and ensuring cargo and passenger load factors to maintain efficiency
- Pre-flight engine wash and aircraft cleaning for aerodynamics and engine efficiency
- Use of single-engine taxiing
- Intensive flight planning and direct routing, including continuous descent and reduced auxiliary power unit (APU) burn
- Contrail avoidance testing with SATAVIA to reduce non-CO2 emissions and climate impact
- In flight service to reduce waste production and scope 3 waste to CO2 impacts
