 Conlcusions previous LG meeting
 Indicators in the revised SEEA
 Key aggregates: Part I
1) Physical flow accounts
2) Monetary accounts
3) Asset accounts and depletion
 Future issues
 Questions to the London Group
Conclusions previous meeting
 General consensus that indicators are
important and should be included in the SEEA.
 Aggregates resulting directly from accounting
identities should be presented as part of the
standard (Part I).
 Indicators are applications of the accounts and
should be discussed in application chapter (Part
III)
 It is not the Group’s role to recommend a list of
indicators.
 General consensus that the SEEA should not
embrace any particular school of thoughts and
thus it should not advocate the calculation of
composite indices.
Indicators in the revised SEEA
Part I: identification of key aggregates that can
be directtly derived from the standard tables.
Examples:
Part III: general discussion on indicators from
SEEA
– General introduction, policy uses etc.
– Aggregation issues, ratio indicators
– Comparison with international indicator sets
– Indictors derived from economic analyses and
modelling application
Physical flow accounts
1) Conceptual framework
2) Subaccounts
Economy-wide material flow accounts
Residual accounts
Water flow accounts
Energy accounts
Conceptual framework
PSUT
Physical supply
and use tables
by
type of material
(products, used
and unused raw
materials, ecosystem
inputs,
waste and waste
water flows within
the economy,
residuals)
and by
economic (production
branches,
final uses) and
environmental
Activities
PIOT: Physical input

Problems
 Double counting
For example: total material use: natural
resources are conveted into products
 Aggregation issues
For example aggregation of all residuals
Accounting identities within conceptual
Framework do not provide usefull
aggregates that can serve as
significant indicators
Key aggregates from the
subaccounts
Economy wide material flow
accounts

EWMFA indictors still under debat: Aggregation issue
Proposal:
a) include this short list of indicators in Part I and briefly point
out the aggregation issues involved, which are
b) more elaborately discussed in Part III of the revised SEEA.

Net additions to stock
Physical trade balance

Residual accounts
 Gross emissions versus net emissions
 Indicators for specific environmental problems
 Aggregation based on scientific weights may provide
useful indicators.
Net emissions
Absorption / recycling
Net accumulation on national territory
Net cross boundary outflow by env. Media

Energy accounts
 Gross energy flow accounts: double counting
 Net energy supply and use tables more usefull
Total domestic energy extraction

Total energy requirement of the economy
Total net energy consumption
Percentage of renewable energy consumption
Import dependancy

Water accounts
 Total water use and total supply less suitable
Total water abstraction
Total use of water received from other economic units
Total supply of wastewater to other economic units
Total returns
Reused water / total water supply to economic units

Monetary accounts
• Most key aggregates are total amounts, such
as total environmental expenditure, total
environmental taxes, etc.
• Most interesting indicators are ratio indicators
(discussed in Part III)

Future issues
1. A discussion on indicators derived from
hybrid accounts seems useful
2. The various chapters of Part I should include
tables in which key accounting aggregates
are explicitly exposed. A set of these tables
should be developed
3. The same holds for indicators from monetary
accounts
4. The explanation of the indicators and their
applications in Part III (ratio indicators,
indicators derived from analysis etc.) has to
be worked out.
Questions for the London Group
1. Does the London group agree with the proposal
presented in this paper to describe important
key aggregates that can be directly derived
from the standard tables in SEEA Part I and
include a broader discussion on indicators and
their uses in SEEA Part III?
2. Does the London group agree that key
aggregates for physical flow accounts are best
exposed in special tables or sub-accounts (and
not directly from the conceptual framework)?
3. Has the London group additional suggestions
for identifying key aggregates that could serve
as building blocks for SEEA indicators?
