Abstract

Correction for ‘Impacts of a near-future supersonic aircraft fleet on atmospheric composition and climate’ by Sebastian D. Eastham et al., Environ. Sci.: Atmos., 2022, https://doi.org/10.1039/D1EA00081K.

The authors regret that the units for NOx in Table 1 were shown incorrectly in the original article. The corrected version of Table 1 is as shown below
Table 1 Average emissions indices and key information for each fleet. All units are g per kg of fuel burn. Emissions of NOx are given on an NO2 mass basis. Emissions of VOCs are given on a CH4 mass basis. Sulfur emissions are split between SO2 and H2SO4 as described in the main text. Subsonic aircraft BC emissions are calculated for each flight using the FOX method.34 * indicates that a single fleet-wide emissions index is used during all flight phases
Subsonic SST 1.6 SST 2.2
NOx 15 8.8 19
CO 8.3 6.3 15
VOCs 1.0 1.6 10
BC 0.082 0.030* 0.030*
OC 0.020 0.030* 0.030*
Sulfur 0.6* 0.6* 0.6*
H2SO4 0.036* 0.036* 0.036*
H2O 1231* 1231* 1231*
Fuel (kg) per seat km 0.023 0.12 0.20
Total annual fuel burn (Tg) 426 19.3 14.9
Total annual NOx emitted (Tg) 6.5 0.17 0.28
Cruise altitude (km) 9–12 15–17 18–20
Cruise Mach no. <1 1.6 2.2
