Delft - Airlines consumes 2,000,000 liters (528,344 gallons) extra kerosene every day due to grounded Boeing 737 MAX jets reports Dutch aviation portal luchtvaartnieuws.nl.
The site refers to a calculation made by Joris Melkert, an aviation and space technology lecturer at the TU Delft Technology University in Netherland.
Boeing has so far delivered to its customers 376 Boeing 737 MAX jets. They are all now grounded by civil aviation regulators around the world after the Ethiopian Flight 302 crash.
The Boeing 737 MAX consumes around 16 percent less fuel than its predecessor Boeing 737-800, thanks to its new generation engines and the aerodynamic improvements made to the wings. According to Melkert, this results in a fuel saving of 5600 liters (1480 gallons) per aircraft per day.

In its calculation, Melkert assumes that the Boeing 737 MAX operators are temporarily replacing these planes with the previous generation single-aisle jetliners, such as the Boeing 737-800. As a result, airlines consume 2 million liters (528,344 gallons) more kerosene per day, which also means more CO2 emmission.
Replacing the grounded Boeing 737 MAX jets with other new generation single-aisle jets such as the Airbus A320neo is not an option due to long waiting lists for the aircraft.
