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

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

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

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.

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
