Dassault is the only business jet manufacturer having committed, along with the rest of the European aeronautical industry, to 2020 environmental goals set by the Advisory Council for Aeronautics Research in Europe (ACARE) in 2001. One goal is to halve CO2 emissions between 2000 and 2020–measured by passenger mile. However, as business jets are “flying offices” carrying very few passengers, the right metric for them should be fuel burned per mission per mile, Dassault officials believe.
In fact, ACARE’s original goals have since been found to be too ambitious and a recent progress report indicated that only 75 percent of them are expected to be met. This is true for the whole of air transport, not only for business aviation. Dassault has indicated that the efficiency gain between the Falcon 2000EX (certified in 2003) and the Falcon 7X (certified in 2007) is in the 15- to 20-percent range.
