A new analysis of commercial aircraft fuel efficiency from the International Council on Clean Transportation (ICCT) finds that the UN’s aircraft CO 2 standard lags current technology by more than a decade. The ICCT first analyzed the historical trends in fuel efficiency improvement of new commercial jet aircraft in 2009. In 2015, the organization updated the study and refined the analysis by using the UN’s International Civil Aviation Organization’s (ICAO) cO 2 metric value (MV). Average margin to ICAO’s CO 2 standard for new aircraft, 1980 – 2019. Source: The ICCT The new anaysis updates the previous work by taking into account new aircraft types and deliveries from 2015 to 2019, and by including dedicated freighters delivered from 1960 to 2019. The authors followed the general methodology of the 2015 paper and assessed fuel burn via both block fuel intensity in grams of fuel per tonne-kilometer and the MV, […]
