1. H. Schütz, MFA training workshop 31.8.07 EW-MFA Training Workshop – 31. August 2007 Training Session: -DPO – Domestic Processed Output

2. H. Schütz, MFA training workshop 31.8.07 DPO: Domestic Processed Output - Intro

3. H. Schütz, MFA training workshop 31.8.07 DPO: Domestic Processed Output - Intro  DPO indicates total weight of materials released back to the environment after having been used in the domestic economy at any stage  5 major categories – CO2 dominates  Two basic rules to avoid double counting: - specific N2O/NMVOC emissions - emissions landfills and agriculture  No fully standardised methodology yet

4. H. Schütz, MFA training workshop 31.8.07 DPO: Domestic Processed Output – Emissions to air  National GHG inventories (IPCC) -> greenhouse gases; territory principle  CORINAIR (UNECE LRTAP) -> air pollutants; territory principle  NAMEA air emissions -> GHG and Air pollutants by sectors; residence principle  => MFA should follow territory principle,  => should exclude “secondary” emissions resp. account for first gateway to env. only,  => for ev. estimates refer to IPCC,  => include O2 in weight.

5. H. Schütz, MFA training workshop 31.8.07 DPO: Domestic Processed Output – Emissions to air  Exclude emissions from land use and land use changes (-> not relevant for MFA; mainly CO2), from human or animal respiration (mainly CO2 -> balancing items), from international bunkers resp. transport (-> not territory based; mainly CO2; memorandum item)  Exclude CH4 from landfills (“secondary”)  Exclude N20 from product use and NMVOC by solvents (-> dissipative use of products) and N2O from agriculture (fertiliser applications) and wastes landfilled (“secondary”)  Exclude NH3 emissions from agriculture (“secondary”)

6. H. Schütz, MFA training workshop 31.8.07 DPO: Domestic Processed Output – Waste landfilled  Municipal waste landfilled -> data commonly available  Industrial waste landfilled -> poor data availability – estimates could be done for manufacturing industry and construction and demolition waste (excluding unused – see below)  Controlled and uncontrolled landfills -> should in principle account for uncontrolled only, but seems not feasible – evaluate for feasibility in MFA-Questionnaire  Exclude: recycling/reuse, waste materials emitted to air or water, unused extraction (esp. excavated soil), waste incinerated

7. H. Schütz, MFA training workshop 31.8.07 DPO: Domestic Processed Output – Emissions to water  Direct emissions and emissions after passing waste water treatment  Only minor contribution to DPO  NAMEA water?, environmental reports  Exclude N and P from agriculture  Dumping at sea – e.g. waste, but no dredgings (unused materials)

8. H. Schütz, MFA training workshop 31.8.07 DPO: Domestic Processed Output – Dissipative use of products  Data commonly available for mineral fertilisers, pesticides, seeds in agricultural statistics; check for lime in forestry  Data for emissions of N2O and NMVOC from solvents in emission inventories  Data for organic fertilisers may be estimated based on livestock data -> guide  Other data ev. in statistics or environmental reports or maybe estimated  Correct esp. manure for water content

9. H. Schütz, MFA training workshop 31.8.07 DPO: Domestic Processed Output – Dissipative losses  Abrasion, corrosion, erosion at mobile and stationary sources or leakages or losses due to accidents at transport  Few data and experience  Concentrate on data that can be obtained with justified effort  Though losses from buildings and infrastructures are probably quantitatively relevant – research needed
