UNEP
OECD initiation (1992) => IPPC 1995
guidelines, updated 1996
NATIONAL GREENHOUSE GAS INVENTORIES PROGRAMME
1996 Guidelines adopted at COP3
Supplemented by GPG in 2000 and
2003
System adapted to actual needs - very
widely used
Basis for 2006 Guidelines requested
by SBSTA17.

Origins

Aims:
NATIONAL GREENHOUSE GAS INVENTORIES PROGRAMME
Rationalise structure by reducing
number of volumes needed for cross
referencing
Promote consistency between sectors
Resulting structure agreed at IPCC 21
(Vienna 2003):

Volume structure Overview
UNEP
Evolution – users recognise familiar
methods.
NATIONAL GREENHOUSE GAS INVENTORIES PROGRAMME
As with GPG basic principles for 2006 GL
remain:
1) estimates neither under nor overestimates
so far as can be judged
2) uncertainties reduced as far as practicable
 Hence efficient use of resources

Approach
UNEP
As in IPCC 96 Guidelines, plus notably:
NATIONAL GREENHOUSE GAS INVENTORIES PROGRAMME
All GHG with available GWP values
Additional gases that could be used as
substitutes for which GWPs not yet
calculated
Carbon dioxide capture and storage
Methane from abandoned mines.

Coverage
UNEP
 General guidance more prominent and new
simple introduction to inventories introduced
NATIONAL GREENHOUSE GAS INVENTORIES PROGRAMME
 Managed land a proxy for anthropogenic
 Actual annual estimates
 Direct emissions estimation introduced
 Relationship between carbon pools clarified
 Consistent approach to indirect N, not just
agricultural sources
 Could be relevant at project level

Other developments
UNEP
2006 Guidelines are IPCC’s best, most
internally consistent assessment of
inventory science
NATIONAL GREENHOUSE GAS INVENTORIES PROGRAMME
They are an evolutionary development
from the 96 Guidelines plus GPG and
(personal view) could be used in a
manner consistent with the existing
Guidance

Policy Relevance
Timing of adoption clearly a matter for
Parties
