Cirium has published its Global Aircraft Emissions Monitor which provides a measure of CO2 emissions and fuel consumption from global flights.

New insights from the company show that airlines have burnt 40% less fuel from flights in 2021 year-to-date compared to the same period in 2019.The reduction in flight-produced carbon emissions is attributed to the drop in flights worldwide, which are down 29% compared with 2019.

Jeremy Bowen, CEO at Cirium, said: “To achieve the aggressive targets for aviation to reach net zero emissions by 2050, a thorough understanding is needed of all elements of an aircraft used for flights and the exact flight operations.”

The monitor’s custom data calculations are based on hundreds of flight and aircraft variables to ensure maximum accuracy. The variables include actual flight and taxi times, cabin configuration, aircraft operating empty weight, assumed cargo tonnage, aircraft and engine types, winglet equipage, and aircraft age.

Tests conducted on the Global Aircraft Emissions Monitor have validated its accuracy to within 1%.
