The first commercial flight by a low emissions Embraer E190-E2 aircraft at London City airport landed on Thursday.
The Helvetic Airways aircraft flew from Zurich, re-establishing an air link for the global financial community.
Regional carrier Helvetic Airways is operating the route on behalf of partner company Swiss International Air Lines.
London City chief operating officer Alison FitzGerald said: “Welcoming Swiss and Helvetic back, and with the newest LCY-capable aircraft, Embraer’s E190-E2, is a significant milestone for London City.
“It demonstrates how we are collaborating with manufacturers and airlines to introduce more low-emission, low-noise aircraft to our airport, as well as re-establishing a vital business connection which we believe will go from strength to strength as the UK government begins to further reduce barriers to travel.
“Our ambition is to be one of the most sustainable airports of our size in Europe, and it is my expectation that we will be welcoming more of these aircraft with more airlines as the industry recovers from COVID- 19.”
Embraer EMEA sales and marketing vice president Cesar Perreira added: “Thanks to a reduction of almost 20% in fuel consumption and a noise footprint at take-off that is 63% smaller than our previous-generation aircraft, the E190-E2 delivers not only significant reductions in emissions but also a much quieter experience for local residents.”
