SEEA 2003: Issues for Discussion (World Bank) Kirk Hamilton khamilton@worldbank.org Giovanni Ruta gruta@worldbank.org
Issues • Chapter 9: Valuation techniques for measuring degradation • Distinction between monetary accounts and models • Deciding on which assets to value (keeping in mind the full integration objective) • Treatment of transboundary pollution • Use of valuation techniques • Chapter 10: Adjustments to the flow accounts • Need for full integration of asset and flow accounts • Depletion Establish criteria for selecting one set of options • Defensive expenditures Agreement on “gross-gross” method • Development of environmental debt issues
Distinction between monetary accounts and models • Value of asset damages (degradation) is naturally treated in monetary accounts • Models constitute application of existing accounts to analyze policy options • Examples • Maintenance costing • Green economy modelling • Suggestion: present models as applications in Chapter 11
Deciding which assets to value • Degradation = Damage to Assets • Aiming at integration of asset and flow accounts it is important to measure damage to assets • Valuing clean air as an asset is not possible • Valuing health impacts of air pollution is practical, but do we need a corresponding human capital value in the asset accounts
Ch 9: Other issues • Transboundary pollution • Fuller treatment needed • Valuation techniques • Need for new material on valuing morbidity and mortality
Depletion • Establish criteria for selecting one set of options. Options that need clarification • A1-A3 Apportioning resource rents bw Income and Depletion • B1-B3 Treatment of mineral exploration • C1-C3 Additions and deductions to asset accts • D1-D3 Ownership of resources • E1-E4 Treatment of depletion in owner’s balance sheet • Choices made to be reflected in Chapter 8 • Some material could be moved to Chapter 8
Defensive expenditures • Do we agree on “gross-gross” method? • Are there other alternatives?
Producing a fully integrated accounting system • Income, production and saving aggregates should have corresponding changes in asset accounts • Treatment of human capital • Treatment of ecosystem services as externalities thus as satellite accounts (to avoid double counting)
Environmental debt • Is it useful concept? • How should negative prices be treated in the system?
Fundamental question • Valuation is key for policy applications, particularly in low income countries • Are there any participants who believe that the revision of the SEEA should not aim for integrated accounts for income, saving and wealth in value terms?
