Our goal is for industry to play its full part in improving air quality around airports. In 2017, we published a report on UK aviation and air quality. It concluded that aircraft emissions contribute 1% of the UK nitrogen oxide (NOx) emissions and 0.1% of UK particulate (PM10) emissions. The UK aviation industry has already delivered a wide range of emission reduction initiatives, including changes to the way we operate, which can often deliver consequential benefits in other areas such as noise reduction or carbon savings. A range of opportunities are being explored to reduce this further.
