ICP Modelling & Mapping, Convention on Long-Range Transboundary Air Pollution (CLRTAP)
The publication examines how nitrogen pollution affects ecosystems and biodiversity across the UNECE region, using harmonized Critical Load maps, national data, and scenario modelling. It asks which ecosystems remain at risk under future emission pathways and whether the 2040 biodiversity-reduction target is achievable. The publication is aimed at scientists, policy makers, and informed readers involved in CLRTAP and Gothenburg Protocol revision.
