Background • Global warming, acidification, eutrophication, enhanced levels of tropospheric ozone and stratospheric ozone depletion are interrelated problems • However, these problems are usually studied in isolation • Emission inventories are usually limited to only one of the problems and ignore interactions • First step towards an integrated analysis: analyze interactions affecting emissions 3 Adriana Ignaciuk - Environmental System Analysis Group - Wageningen University

Purpose of the study To analyze some basic characteristics and requirements of emission inventories for Europe to be used in integrated assessments that analyze future global warming, acidification, eutrophication and ozone related problems simultaneously 1 Interactions between emissions and underlying processes 2 Existing emissions inventories: comparison of characteristics 3 Comparison of reduction strategies in model databases 4 Basic requirements of emission inventories for integrated analyses in Europe 5 Adriana Ignaciuk - Environmental System Analysis Group - Wageningen University

Four types of interactions between air pollutants • Human activities giving a rise to emissions of more then one gas e.g. energy use is a source of CO 2 , NO x , SO 2 , N 2 O • Biogenic and biogeochemical processes underlying emissions of more than one gas e.g. denitrification is a source of NO x and N 2 O • Reduction strategies affecting more then one pollutants e.g. switch from coal to natural gas reduces SO 2 and lowering NO x • Effects of changes in the environment on emissions e.g. global warming increases microbiological production of N 2 O 6 Adriana Ignaciuk - Environmental System Analysis Group - Wageningen University

Comparison of emission inventories •Emission inventories databases •EDGAR: Emission Database for Global Atmospheric Research •CORINAIR:CO-oRdination d'INformation Environmentale •EMEP: Monitoring and Evaluation of the Long Range Transmission of Air Pollutants in Europe •IPCC: National Communication Database for GHGs •PER: Pollutant Emission Register for the Netherlands •Model databases •IMAGE:Integrated Model to Assess the Greenhouse Effect •RAINS:Regional Air pollution INformation System for Europe •LOTOS: LOng Term Ozone Simulation model for Europe 7 Adriana Ignaciuk - Environmental System Analysis Group - Wageningen University

Characteristics of emission inventories for Europe Number of pollutants included range from 1 (METDAT) to ~170 (PER) Source categories of emissions included range from 20 (LOTOS) to 375 (CORINAIR) Spatial system boundaries are Europe (EMEP) or world (IMAGE2.0) Spatial aggregation level is country based (CORINAIR) or gridded (LOTOS) Temporal system boundaries range from 1 year ( LOTOS) to 1890-1995 (EDGAR) Temporal aggregation level range from annual totals (RAINS) to diurnal profiles (LOTOS) Uncertainty assessment limited Methods of emission estimation: mostly emission factor approach 8 Adriana Ignaciuk - Environmental System Analysis Group - Wageningen University

Conclusions (1) 1 Interactions • Four types of interactions between air pollution problem exist that affect emissions 2 Emission databases • Emission database differ considerably with respect to gases included, spatial and temporal characteristics and number of sources included • Poor uncertainty assessment • Most emissions are based on simple emission factor approaches 3 Reduction strategies in models • Models usually do not include both demand and supply side options for a wide range of gases • Most models do not include interactions between pollutants 12 Adriana Ignaciuk - Environmental System Analysis Group - Wageningen University

Conclusions (2) 4 Requirements for emission data for integrated analyses could be based on the data needs of economic, atmospheric and policy-oriented models • Atmospheric models: need high resolution temporal and spatial data • Economic models: need detailed specifications of source categories • Policy oriented models: need long time datasets and reduction strategies A consistent dataset meeting all these needs for all compounds may not be easy to achieve 13 Adriana Ignaciuk - Environmental System Analysis Group - Wageningen University

Recommendations • Linking of existing emission inventories • Make inventories more flexible • Soft linking of existing models for the purpose of scenario analyses • Linking of models for optimization analysis • Develop a modeling framework for an integrated analysis of different air pollution problems accounting for all interactions between pollutants 14 Adriana Ignaciuk - Environmental System Analysis Group - Wageningen University
