The Integrated Approach to Nitrogen and AERIUS

The Integrated Approach to Nitrogen (PAS) is the Dutch policy for coping with the issues around nitrogen. The PAS will ensure that the objectives of European nature policy are being achieved, while creating the necessary room for economic development.

AERIUS, the calculation tool of the PAS

The AERIUS calculation tool is one of the cornerstones of the Integrated Approach to Nitrogen (PAS). It calculates the level of nitrogen deposition in Natura 2000 areas, caused by projects and development plans. AERIUS supports the issuing of permits for economic activities that involve the emission of nitrogen, and monitors whether the total nitrogen burden continues to decline. In addition, AERIUS also facilitates spatial planning in relation to nitrogen.

For all areas and sectors

AERIUS may be used for calculations for all nitrogen-sensitive Natura 2000 areas and all nitrogen-emitting sectors (agriculture, industry, and traffic & transport). In this way, AERIUS is in keeping with the area- and sector-exceeding character of the PAS.
