Mono-nitrogen oxides (NOx) are a specific metric in the 2017 GRI report to be 634 tonnes stated under Disclouse 305-7 Nitrogen (NOx), sulfur oxides (SOx), and other significant air emissions. This is an increase from 2016s result stated in the GRI 2017 report to be 512 tonnes of mono-nitrogen oxides. In 2014 Clariants NOx levels were 872 tonnes, sustaining that although the spike in NOx's emmited in 2017, Clariant has decreased its NOx's over the last three years. Under Review of Results, 1.2.3 Pollution, 2017 Integrated Report, Clariant state "Clairant implemented several measures to improve its performance regarding pollution prevention. For example, Clariant installed de-sulfurization control devices and dust collectors to reduce the emission of sulfur oxides. Air emissions and waste water quality of all sites is monitored closely. The parameters tracked for air emissions include volatile organic compounds (VOC), sulfur oxides (SOx), and nitrogen oxides (NOx)."
