However, around 400 aircraft are in excess of 40 years. To date, the total number of permanent retirements of business jets has been low. However, as a result of emerging environmental concerns, new regulations and airspace modernization, the retirement of the oldest business jets is expected to accelerate. Environmental regulations include potential airport restrictions on Stage 2 business jet operations and the introduction of the Emissions Trading Scheme (ETS) in Europe taking effect in 2012. The ETS will penalize aircraft types with older technology engines that burn more fuel and therefore emit more greenhouse gas (CO 2 ). Similarly, planned airspace modernization in the United States (FAA NextGen), in Europe (Single European Sky) and elsewhere will require advanced flight deck avionics technologies. It may not be economically feasible to retrofit older aircraft cockpits with the required avionics technology, rendering these types obsolete. These dynamics will result in a reduction of the business jet fleet half-life (age at which 50% of aircraft have retired) from 40 years in 2010 to 30 years in 2030. The amount of aircraft that retire within the forecast period will vary considerably by region. Naturally, the regions having well- established business jet fleets and older average fleet ages will experience the greatest numbers of retirements. Regions that currently have relatively small business jets fleets, such as China, will experience relatively fewer business jet retirements during the forecast period.
