The service was the first visit to Dublin by this aircraft, which is specially-painted as the flagship of the Etihad Greenliner Programme, an initiative by the airline to help make aviation more sustainable.
As well, as a parting gesture on National Day, the departing flight was operated mainly by Irish crew, originally from Dublin, Tipperary, Monaghan, Leixlip, Boyle and Belfast, Northern Ireland.
The airline said: “Yesterday’s initiative was a positive and productive action by Etihad and a range of industry partners in the midst of the Covid-19 virus pandemic, which is heavily impacting the global air transport industry.
“Boeing is a foundation partner of the Etihad Greenliner Programme, through which the airline is working on a range of initiatives, including testing new technologies, procedures and initiatives designed to help advance sustainable air services.
“Another key partner is GE Aviation, which manufactures the engines powering Etihad’s Boeing 787 and 777 fleets, and discussions are progressing with other entities including airports and research organisations to help improve efficiency and reduce environmental impact.”
