Empirical critical loads of nitrogen confirm European wide exceedances

The risk of deposition of nutrient nitrogen in Europe, including Natura 2000 areas, is underpinned by a novel compilation of empirical critical loads and uncertainty analysis inspired by the IPCC. Collaboration with the network under the Convention for Long Range Trans-boundary Air Pollution improves the ability of the Coordination Centre for Effects (CCE) to assess the temporal and spatial development of this risk for support of European air pollution policy development.
