Individual aircraft are internationally certified according to their noise level, emissions of oxides of nitrogen (NOx) and emissions of particulates during landing and take-off. The Department uses the noise data of individual aircraft in models that build up a map of the total noise at designated airports. These are then published.
The project for the sustainable development of Heathrow is collating the total emissions inventory for different scenarios. The basic aircraft emissions data are derived from the publicly available certification data for each type of aircraft. We will be consulting on this shortly.
The Civil Aviation Act 2006 provides powers for all airports to introduce charges that reflect the noise and NOx generated by each aircraft type. In addition to these charges penalties can be imposed for exceedences of noise levels specified in the noise control schemes.
