Emissions of nitrogen oxides (NOx) in the United Kingdom totaled 643,300 metric tons in 2022. Road transportation was the largest source of nitrogen oxides, accounting for more than 30 percent of total emissions that year, while non-road transportation contributed an additional 15 percent. Annual emissions of NOx in the UK have fallen considerably in recent decades due to stricter regulations and the introduction of catalytic converters which reduce toxic gases from vehicle exhausts.
