EasyJet has equipped all of its aircraft with Descent Profile Optimization (DPO) and Continuous Descent Approach (CDA) software — new, cutting-edge software that can significantly reduce carbon emissions and achieve significant fuel savings. This fleet-wide investment allows easyJet to save up to 1% on fuel, permanently, a reduction of 88,600 tonnes of carbon dioxide per year, which equates to 16,100 times around the world by car.
DPO and CDA to reduce emissions…
EasyJet announced on October 23, 2023 the completion of the modernization program for its entire fleet, which enabled all of its aircraft to be equipped with the technology peak DPO (Descent Profile Optimizationn) from Airbus, as well as CDA technology (Continuous Descent Approach) for compatible and newer aircraft in the easyJet fleet. The DPO feature is a fuel-saving initiative that updates the Flight Management System (FMS). It allows aircraft to descend from cruising altitude using only engine thrust at idle, reducing fuel consumption and leading to a proportionate reduction in carbon emissions. The Continuous Descent Approach (CDA) works in tandem with the DPO to reduce noise.
…But also the noise
The multi-million pound modernization programme, announced last year, is an integral part of the airline’s roadmap to achieving carbon neutrality by 2050. This program will enable easyJet to achieve significant and permanent reductions in carbon emissions in the short term by allowing optimized descent trajectories. In addition to fuel savings and reduced carbon emissions, Descent Profile Optimization (DPO), which complements the Continuous Descent Approach (CDA), will also help reduce noise. A benefit for airlines and their customers, but also airports and surrounding communities, due to stricter noise regulations which are increasingly applied.
