In 2019, nitrogen oxide emissions amounted to 160.2 thousand tonnes of nitrogen dioxide in Belgium. To achieve the sustainable development goal by 2030, this figure must decrease by 59% between 2005 and 2030. This objective will be reached by continuing the trend since 2000 (data available in November 2021). The nitrogen oxide emissions are therefore developing favourably.

Definition: Nitrogen oxide emissions (NOx) measure the total NOx emissions on Belgian territory, expressed in kilotonnes of nitrogen dioxide (kt NO2). NOx is emitted mainly during the combustion of fossil fuels in engines, boilers and industrial processes. Data are compiled by the Interregional Environment Agency and are available on the website of the European Environment Agency.

To make a comparison between Belgium and the EU27, emissions are calculated in kilograms of emissions per capita.

Goal: Nitrogen oxide emissions must decrease by 59% between 2005 and 2030.

The Sustainable Development Goals or SDGs adopted by the UN in 2015 include target 11.6: “By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management.”

Following the revision of the Gothenburg Protocol in 2012 (UNECE, 2012), Directive (EU) 2016/2284 sets emission reduction targets for some atmospheric pollutants (Official Journal of the European Union, 17/12/2016). From 2020 onwards, Belgium's NOx emissions must be 41% lower than in 2005. From 2030 onwards, they must be 59% lower. Emissions related to agriculture (livestock manure and agricultural soil management, i.e. 8% of the total in 2018) are not covered by this Directive.

International comparison: between 1990 and 2019, the decrease in nitrogen oxide emissions in Belgium (-63%) was almost equivalent to that observed in the EU28 (-59%). With regard to average emissions per capita in 2019, NOx emissions amounted to 13.9 kg/capita in Belgium, slightly above the European average of 13.7 kg/capita. When Member States are divided into three groups, Belgium is part of the group with average performance and is below the European average in 2019. In that year, Italy ranked first with 10.5 kg/capita and Luxembourg last with 30.9 kg/capita.

UN indicator: the selected indicator does not correspond to any monitoring indicator for the SDGs but is related to target 11.6., which requests to pay “special attention to air quality”.
