To ask the Secretary of State for Environment, Food and Rural Affairs what the annual emission of (a) NOx, (b) SOx, (c) Carbon Dioxide and (d) particles in the area surrounding Stansted airport was in (i) 1997, (ii) 1998 and (iii) 1999. [106518]
The following table shows estimated emissions of NOx, SOx, Carbon Dioxide and particulates (PM10) for Stansted Airport in 1997, 1998 and 1999:
| Emission(tonnes) | 1997 | 1998 | 1999 |
| NOx (as Nitrogen Dioxide) | 502 | 625 | 805 |
| SOx (as Sulphur Dioxide) | 34.9 | 43.4 | 56.1 |
| Carbon Dioxide (CO2) | 106,319 | 132,258 | 171,070 |
| Particulates (PM10) | 9.5 | 11.8 | 15 |

National Atmospheric Emissions Inventory. Aircraft emissions during the complete take off and landing cycle up to 1,000m are allocated to the airport. Consequently a proportion of the emissions are emitted at some height and horizontal distance from the boundaries of the airport. Emissions are calculated from aircraft movement data. The emissions are based on the number of aircraft movements at the airport in relevant years. Emissions from aircraft support vehicles are based on UK totals for this sector apportioned pro-rata according to the number of aircraft movements.
