1 Classification of physical flows -A proposal – Issue 2 Bram Edens, Alessandra Alfieri Odd Andersen, Ralf Becker UNSD London Group Meeting Canberra 27-30 April 2009

2 Issues Definition of product, waste, residualDefinition of product, waste, residual Proposal for a reorganization of the structure of classification of physical flowsProposal for a reorganization of the structure of classification of physical flows Scope of waste accountsScope of waste accounts

3 Definition of products, by-products, waste, residual 2008 SNA2008 SNA Products are goods and services that are the result of production By-products are products necessarily produced with principal products (wheat and straw) Joint products are products produced simultaneously by a single activity (sugar and molasses) No definition of waste or residual

4 Definition of products, by-products and waste (Cont’ed) CPC ver.2CPC ver.2 In general follows SNA definitionIn general follows SNA definition Covers everything that is transacted within the economy (products and waste)Covers everything that is transacted within the economy (products and waste) Principles of CPCPrinciples of CPC Industrial originIndustrial origin Physical characteristic of productPhysical characteristic of product Harmonization with HS (waste)Harmonization with HS (waste) Waste scattered in several CPC classesWaste scattered in several CPC classes Value is not a criterionValue is not a criterion

5 Definition of products, by-products and waste (Cont’ed) Waste Framework DirectiveWaste Framework Directive Products materials created in a production processProducts materials created in a production process By-products materials deliberately produced in a production process but may or may not be waste.By-products materials deliberately produced in a production process but may or may not be waste. For a material to be a by-product 3 tests have to hold simultaneously: For a material to be a by-product 3 tests have to hold simultaneously: Further use is a certaintyFurther use is a certainty Material can be reused without further processingMaterial can be reused without further processing Part of a continuous process of productionPart of a continuous process of production

6 Definition of products, by-products and waste (Cont’ed) Waste Framework DirectiveWaste Framework Directive Waste Material for which the generator has no further use for own purpose of production, transformation or consumption and which he discards or intends to or is required to discardWaste Material for which the generator has no further use for own purpose of production, transformation or consumption and which he discards or intends to or is required to discard Can be generated at any stage of production or consumptionCan be generated at any stage of production or consumption Commercial value and economic reutilization are irrelevantCommercial value and economic reutilization are irrelevant

7 Definition of products, by-products and waste (Cont’ed) SEEA-2003SEEA-2003 Products are goods and services produced within the economic sphere and used within it. Include also residuals that have positive value to the generatorProducts are goods and services produced within the economic sphere and used within it. Include also residuals that have positive value to the generator Residuals are not uniquely definedResiduals are not uniquely defined Incidental and undesired outputs from the economy that have zero value to the generatorIncidental and undesired outputs from the economy that have zero value to the generator Flows from the economy to the environmentFlows from the economy to the environment Include dissipative use of productsInclude dissipative use of products Waste is sub-item of residual – solid waste that stays within the economyWaste is sub-item of residual – solid waste that stays within the economy

8 Comment Definition of products is in general consistent across frameworksDefinition of products is in general consistent across frameworks Definition of residuals and waste is not:Definition of residuals and waste is not: SEEA-2003 definition is linked to valueSEEA-2003 definition is linked to value WFD definition is linked to the notion of “discard”WFD definition is linked to the notion of “discard” Material discarded can be:Material discarded can be: Delivered to another industry for further use without processingDelivered to another industry for further use without processing Discharged to a landfillDischarged to a landfill (Discharged to the environment)(Discharged to the environment)

9 Proposals on definitions Definition of products should be fully consistent with that of the SNADefinition of products should be fully consistent with that of the SNA Waste – use definition of WFDWaste – use definition of WFD Explain the notion of discard and expand it to include also discharge of materials back to the environment (e.g. to uncontrolled landfill, to ambient water)Explain the notion of discard and expand it to include also discharge of materials back to the environment (e.g. to uncontrolled landfill, to ambient water)

10 Physical flows classification SEEA-2003SEEA-2003 Ecosystem inputsEcosystem inputs Natural resourcesNatural resources ProductsProducts ResidualsResiduals Each flow uses its own classificationEach flow uses its own classification Flows from the environment to the economy Flows within the economy and from the economy to the environment

11 Proposals – Structure of classification Flows from the economy to the environmentFlows from the economy to the environment Natural resourcesNatural resources Additional itemsAdditional items Flows within the economyFlows within the economy Flows from the economy to the environmentFlows from the economy to the environment Emissions to airEmissions to air Emissions to waterEmissions to water Solid waste to uncontrolled landfillSolid waste to uncontrolled landfill Dissipative use and dissipative lossesDissipative use and dissipative losses Return flows of waterReturn flows of water Additional items (evaporation, losses, etc.)Additional items (evaporation, losses, etc.)

12 Proposals on classifications Use CPC for all physical flows, if relevant categories exist, and complement it with additional categories for flows from the environment to the economy and back to the environmentUse CPC for all physical flows, if relevant categories exist, and complement it with additional categories for flows from the environment to the economy and back to the environment CPC non appropriate for wasteCPC non appropriate for waste Use EWC Stat for waste – replace CPC 39 plus possibly other CPC classesUse EWC Stat for waste – replace CPC 39 plus possibly other CPC classes

13 Advantages of the proposal Alignment with economic and waste statisticsAlignment with economic and waste statistics SNA monetary flows relate to service paid (CPC 94)SNA monetary flows relate to service paid (CPC 94) SEEA physical flows present the volume (CPC 39)SEEA physical flows present the volume (CPC 39) Destination of flows seen in the SUT (waste product vs. waste residual)Destination of flows seen in the SUT (waste product vs. waste residual) Integration with EW-MFAIntegration with EW-MFA Coherence in recording dissipative use of products (not residuals but flows economy to the environment)Coherence in recording dissipative use of products (not residuals but flows economy to the environment) Full consistency with the SEEAWFull consistency with the SEEAW

14 Waste flows

15 Proposal on scope of waste accounts Use broad scope of waste accounts to include:Use broad scope of waste accounts to include: Flows of discarded materials into ISIC 37Flows of discarded materials into ISIC 37 Flows used as intermediate consumption by other industriesFlows used as intermediate consumption by other industries Flows of materials discharged into the environment (e.g. uncontrolled landfill, ambient water – air emission covered by emission accounts)Flows of materials discharged into the environment (e.g. uncontrolled landfill, ambient water – air emission covered by emission accounts) Secondary wasteSecondary waste

16 Next steps Outcome of LG discussions will be presented at the next UN Expert Group Meeting on Classifications (Sept 09)Outcome of LG discussions will be presented at the next UN Expert Group Meeting on Classifications (Sept 09) Outcome of EGM shared with LGOutcome of EGM shared with LG

17 Questions to LG 1.Do you agree with aligning the definition of products with the that of the 2008 SNA and CPC? 2.Do you agree to use the definition of waste based on EWC? 3.Do you agree with the typology of flows proposed: flows from the environment to the economy, flows within the economy, and flows from the economy to the environment? 4.Do you agree to use CPC to classify all physical flows (except for waste) complemented by additional categories? 5.Do you agree to replace CPC Division 39 covering solid waste and possibly the most important CPC classes with EWC Stat for classifying waste? 6.Do you agree with the suggested expanded scope of the waste accounts to include also solid waste discharged to the environment (e.g. uncontrolled landfill), including materials discharged to ambient water?

18 Advantage of the proposal Physical flows in standard tables are consistent with the SNA monetary flowsPhysical flows in standard tables are consistent with the SNA monetary flows Standard tables identified, if information is available all types of losses, including theftStandard tables identified, if information is available all types of losses, including theft Supplementary tables regroup the losses to show gross aggregates (and derivation of productivity indicatorsSupplementary tables regroup the losses to show gross aggregates (and derivation of productivity indicators Theft is separately identified, if information is available as a different flow neither within the economy nor as a flow from the environment to the economyTheft is separately identified, if information is available as a different flow neither within the economy nor as a flow from the environment to the economy

19 Disadvantage of the proposal Energy statistics recordEnergy statistics record production of secondary products gross (including losses)production of secondary products gross (including losses) production of primary products net of lossesproduction of primary products net of losses For secondary energy products, standard tables are inconsistent with energy statisticsFor secondary energy products, standard tables are inconsistent with energy statistics

20 Questions to the London Group 1.Does the London Group agree with the typology of losses (Section B)? 2.Does the London Group considers useful a table on the presentation of gross supply (Tables 2 and 5)? 3.Does the London Group agree with the suggested recording of losses during extraction, distribution, storage and conversion as presented in Tables 3 and 5? 4.Does the London Group agree with the supplementary tables for theft?
