Sulphur Dioxide (SO2) is a highly reactive gas, that along with Nitrogen Oxide (NOx) and Ammonia (NH3) is measured as a precursor to acid rain.
Sector classification is based on the NACE code, which is the industry standard classification system for economic activities in the European Community.

NOx emissions by rail transport in the United Kingdom (UK) from 1990-2017
This statistic shows the total amount of nitrogen oxide (NOx) emissions through rail transport in the United Kingdom (UK) from 1990 to 2017. It shows that emissions have increased since 1990, although they have decreased since the peak of * metric tons of sulphur dioxide (SO2) equivalent emitted in 2000.
