Emissions of nitrogen oxides in Spain were 588,100 metric tons in 2022. NOx emissions in Spain have experienced an overall reduction of 55 percent since 1990.
Nitrogen oxides (NOx) mainly include nitric oxide (NO) and nitrogen dioxide (NO₂), which contribute to the formation of smog and acid rain. The main source of NOx in Spain is road transportation.
