In June 2007, EasyJet announced plans for the construction of its own airliner, dubbed "EcoJet". It was claimed to possess improved fuel efficiency over contemporary airliners. To achieve this, the EcoJet was described as using propfan engines, as well as being constructed with extensive use of carbon fibre composite material. At the time of the announcement, it was stated that the first flight was scheduled to occur sometime during 2015. Speaking at the time, EasyJet chief executive Andy Harrison commented that: "We have not developed a new concept. We have taken ideas from Boeing, Airbus and the engine manufacturers and put them together." Harrison claimed that the EcoJet, combined with other improvements in the industry, would enable a 50% reduction in greenhouse gas emissions within eight years. However, there has been few announcements on the project since then.
