Exhaust Emissions: Greater London
- Question
-
To ask the Secretary of State for Transport, what assessment he has made of the effect of aircraft on nitrous dioxide levels in Greater London.
- Answer
-
Air quality emission levels by mode are only compiled at a national level by the National Atmospheric Emissions Inventory. Its estimates are updated annually. Emissions from road vehicles are by far the greatest source of nitrous dioxide levels in Greater London.
The main impact of aviation on ground local air quality relates to emissions during the landing and take-off phase up to about 3000 feet. Above this height the oxides of nitrogen and particulate matter which can cause respiratory problems get dispersed.
