How are NOx emissions from industrial steam boilers regulated in the EU?

Despite the improvement produced by raising awareness among different industries about the climate change problem in recent years, the EU Environment Program takes into account that ecosystems continue to suffer the negative consequences of excessive nitrogen and sulfur in our atmosphere associated with transport emissions, different agricultural practices and the generation of electricity. The emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) generated by industrial steam boilers must be regulated in this regard so that the environmental impact is as low as possible. ATTSU, in that sense, bare in mind its social responsibility and has always set out to move forward by investing in the environment and in the relations with its partners, among which are the NGOs that defend the environment.

Directive (EU) 2015/2193 requires to intensify efforts to comply with the Union's air quality legislation and and to determine strategic actions and objectives right after 2020. To this end, it establishes regulations that seek to control and reduce sulfur dioxide (SO2), nitrogen oxides (NOx) and particles air emissions coming from medium combustion facilities to reduce their risks to human health and the environment. It also states that such limitations should not result in the increase of other pollutants such as carbon monoxide.

NOx emissions from medium-sized combustion plants with a nominal thermal power of more than 5 MW must comply with a series of restrictions that will be applied more stringently over the years. Thus, in 2025 a considerable new restriction of these emissions will be applied, which will be intensified as of 2030.
