1 EPNB Guidance Document and its Annexes Wilfried Winiwarter

2 Overview The N cycle/cascade: from Material Flow Analysis to National Nitrogen Budgets Achievements: Status of development Example countries Outlook beyond Europe: Towards INMS

3 Cascade mass consistency multiple pools flows between pools

4 The Nitrogen cascade Reactive Nitrogen (Nr) covers all forms of N except for N 2 Environmental path of Nr is a short cascade, but may take multiple directions N fixation (activation) as source, Nr destruction/immobilization as sink Co-benefits vs. tradeoffs in measures

5 Choice of budget level Global: planetary boundaries Continental: limited interaction Individual country: Trade and transport become dominant vs.: legislative frameworks require data

6 Problem-oriented legislation National for direct national impacts EU directives to be implemented as national law (European Union specific) International agreements to be ratified into national legislation requires national level data collection impacts on the same economic sectors interferes with other relevant regulation

7 Top-down budgets Leip et al., 2011 ENA, Leip et al. (2011)

8 Guidance Document on National Nitrogen Budgets under UNECE air convention Links to existing reporting requirements (e.g., UNFCCC for pool definitions) Using existing data repositories (UNECE) Trade & transport considered

9 Guidance Document on National Nitrogen Budgets under UNECE air convention Links to existing reporting requirements (e.g., UNFCCC for pool definitions) Using existing data repositories (UNECE) Trade & transport considered

10 National Nitrogen Budgets

11 Pool Materials Specific issue: unreactive nitrogen compounds, locked Nr

12 Pool Agriculture Specific issue: harmonizing existing guidance

13 Pool Forests/semi-natural veg. Specific issue: estimating soil processes

14 Pool Hydrosphere Specific issue: outer boundaries

15 Substructure of pools e.g., Materials and products in industry

18 Time trends (here: Germany) Source: Geupel, 2016

19 Comparisons between countries Data: Leip et al., 2011

20 Outlook current developments Task 1.1.1: Development of National N budget approaches (Winiwarter/Hayashi) NNB guidance for use in demonstration areas, i.e. developing countries Contributing to an International Nitrogen Assessment

21 Structure Towards INMS International Nitrogen Management System Data need & concepts Improved management practices, Mitigation, Adaptation Informing modelling requirements C1: Tools and methods for understanding the N cycle Opportunities, Local/region priorities, Policy context, Local data, Barriers-to-change C3: Regional demonstration & verification C2: Global & regional quantification of N use, flows, impacts & benefits of practices C4: Awareness raising & knowledge sharing Options & Scenarios, including Cost-Benefit-Analysis Devlpt. of policy homes, Public awareness, Consensus building, Improved basis for transformational actions on N management

22 Policy arena Recognizing Planetary Boundaries Climate UNFCCC Biodiversity CBD + Ramsar, UNCCD Stratosphere Montreal Protocol Maximizing Co-benefits Air Quality LRTAP + regional bodies Water & Marine GPA + regional bodies Addressing key threats Intergovernmental Partners GEF, UNEP, FAO, WMO, GAW, WHO, UNDP, IEA, OECD, UNECE, IPCC, IPBES Policy Arena for Nitrogen UNEA, OECD Overarching Goals including Economy Wide Nitrogen Use Efficiency More food and energy with less pollution INMS International Nitrogen Management System (Science Support Process linking threats & benefits) Sutton et al. (2018) Food & Energy CFS, HLPF SDGs + regional Trade & Economy WTO + regional bodies Overcoming Barriers Specialist Partners INI, GPNM, TFRN, SCOPE, Future Earth, EU-NEP, Business, Farmers, CSOs etc

23 Compare to workplan (Aarhus 17) WORKPLAN Finalization of the Guidance Document on national nitrogen budgets Energy annex Waste annex Scientific paper(s): N2016/Melbourne Structure of reporting - Reporting Template Proposal for test call for N budgets Continued interaction with INMS, other organisations on budget work User workshop Farm nitrogen budgets Dynamic tool on N budgets

24 Conclusions: Policy impacts, future applications N budgets appear in EU legislation Member States may establish a national nitrogen budget Extension to more countries will further allow meaningful comparisons Practice feedback welcome and needed it is expected to improve usability
