Home / Our Science / Emissions


Chemical emissions are one of the largest sources of uncertainty in predictions of how air pollution will change in the future. Chemical emissions from human sources are especially difficult to predict.

We focus on evaluating chemical emissions in real-world settings, such as measuring emissions from vehicle tailpipes or using our research aircraft to measure emissions on a national scale.

We specialise in taking measurements at the source of pollution, including in-situ mass spectrometry and optical spectroscopy.

Our approach combines air pollution observations with computer modelling techniques. This is the best way to find out how much pollution is being released from different sectors including transport, energy generation, and agriculture.

Our research will improve the UK’s ability to simulate air pollution using computer models, the accuracy of air quality forecasts, and inform government policy.
