• Introduction

• CPC
• Three subsystems
• Industrial branches
• Overlap between subsystems
Three subsystems
Energy (Joules)
MFA (Kg)
Water (m3)
Introduction:
One consistent classification
• Compatibility
between subsystems
• Energy (Joules)
• Materials (Kg)
• Water (m3)
• Compatible National accounts and physical
accounts
• Compatible industrial branches
• Overlap consistently classified
Usefulness CPC
Waste accounts: Not included are manure,
discarded equipment, mineral wastes etc. No
distinction between hazardous and nonhazardous waste.
Energy accounts: Not specified as energy
carrier are biomass (except fuel wood), solid
waste and gas like biogas. Sources electricity
(solar, wind, coal etc.) not specified.
CPC seems not sufficient. More discussion will
follow later this session
Classification subsystems (I)
MFA: Build up from different data sources.
Therefore double counting may occur.
- waste products my appear in NA data or
international trade data.
- Dissipative losses may appear in the air,
water and waste accounts.
Classification of subsystems (II)
Waste accounts: Use the European Waste
Statistic Regulation.
Other residual accounts: Use the
classification presented in annex 4 of the
SEEA.
Discussion on detailed classification subsystems will follow later.
Classification industrial branches
Recommendation: Compatible industrial
branch classifications between
subsystems.
Recommendation: ISIC industrial
classification on a 2-digit division level for
manufacturers and a 1-digit section level
for all other industrial branches is sufficient
or is more detailed required ?
(see for example paper on SEEA-MFA)
Overlap subsystems (I)
Are the following issues required to satisfy
compatible classification of the three
subsystems and the National accounts:
Materials - Energy: Materials in the MFA
should be classified energetic or non
energetic.
Materials - Energy: Classifications in the
energy accounts should match the level in
the MFA
Overlap subsystems (II)
Energy - Water: Electricity generated by
hydropower should be classified.
Materials – National accounts: in MFA a
distinction between waste products and
residuals must be made.
Are there issues regarding the overlap between
the three subsystems (materials, energy and
water) and the National accounts that have not
been addressed here?
Questions for the London Group
1. Do you agree that Compatible industrial
branch classifications between subsystems
is required for all three subsystems ?
2. Is ISIC industrial classification on a 2-digit
division level for manufacturers and a 1digit section level for all other industrial
branches sufficient ?
Questions for the London Group
3. Do you agree with a classification of waste
according to the classification of the European
Waste Statistic Regulation ?
4. Do you agree with the residual classification
(apart from solid waste) as presented in the
SEEA 2003 ?
Questions for the London Group
5. Do you agree that materials in de MFA used
for generating energy should be classified to
its purpose of use ?
6. Do you agree that electricity generated by
hydropower should be classified?
7. Do you agree that a distinction between
waste products and waste residuals in the MFA
should be made?
