Update on issues related to the IPCC 2006
Guidelines

• Simon Eggleston
• IPCC Task Force on National Greenhouse Gas
  Inventories

2
Introduction

• Guidelines have evolved from 1996 to 2006
• Major step was the Good Practice Guidance (GPG)
• Complete, consistent, comparable, transparent,
  and accurate inventories taking account of
  available resources
• Major change was from 1996 LUCF to GPG LULUCF
• 2006 Guidelines 2.5 years work, 250 authors
• 4 categories (Energy, IPPU, AFOLU Waste)
• Require similar resources to implement as the
  1996 Guidelines plus the two volumes of GPG
• Does not pre-empt accounting choices methods
  generate all information needed
• The best globally applicable methods

2006 Guidelines

• Update and expand earlier guidelines
• While remaining consistentancy with earlier
  guidelines
• Have a general introduction to inventory
  compilation
• Include a new chapter on data collection
• Include updated default values and methods
• Restructure main categories and sub-sectors to
  clarify and simplify inventories and to reduce
  chance of double-counting
• Include methods for sectors previously included
  in other sectors or under other
• Include additional direct greenhouse gases for
  which estimation methods are provided

Tiers and Key Categories
Many defaults updated in 2006 Guidelines
5
New gases in 2006 Guidelines (IPPU)
Methodologies in 2006 Guidelines
By-product fugitive emissions
Only Gases with methods available included in
2006 Guidelines
6
Direct CO2 Indirect N2O
2006 Guidelines give methods to calculate this
2006 Guidelines CO2 Emissions do not include
this
2006 Guidelines CO2 Emissions
2006 Guidelines includes ALL NH3 NOx Emissions

Estimation of Actual Annual Emissions
(Fluorinated compounds, Landfills)

• For a few sources in the 1996 Guidelines GPG,
  the simplest methodology estimates a potential
  emission (current and future emissions) rather
  than the actual annual emission.
• In the 2006 Guidelines, simple default methods
  estimate actual annual emissions in the year they
  occur, thus removing the need for potential
  emissions.
• This allows
• the emission reductions of abatement techniques
  to be estimated
• ensures that the methods are compatible with
  higher tier methods.

Improvements in AFOLU Guidance

• Wetlands
• 2006 GL has complete coverage of peat lands
• 2006 GL improved coverage of flooded lands but
  some guidance is incomplete and awaits further
  scientific investigation
• Fires
• Guidelines have increased consistency and
  coverage of fires
• All emissions from fires reported in a separate
  category for increased transparency
• Managed land is used in these guidelines as a
  proxy for identifying anthropogenic emissions by
  sources and removals by sinks.
• use of managed land as a proxy for anthropogenic
  effects was introduced in the GPG-LULUCF and is
  consistent with the Revised 1996 Guidelines.
• Managed land is land where human interventions
  and practices have been applied to perform
  production, ecological or social functions

11
Subsequent IPCC Work

• Helsinki 2008. (LULUCF/AFOLU Guidance)
• Concluded that additional assistance on activity
  data would assist LULUCF/AFOLU compilers rather
  than methodological work
• Also needed Consideration of Uncertainties and
  Tier 3 models, and improvement of EFDB
• Brazil 2009 (Managed Land)
• No current alternative to the use of managed
  land as a proxy for identifying anthropogenic
  emissions was identified
• Possible alternatives need further scientific
  development and subsequent assessment

12
Summary

• 2006 Guidelines
• Maintain the same basic methodological approaches
  from 1996 Guidelines, GPG 2000 GPG LULUCF
• Improved and updated default values
• Only actual emissions potential estimates not
  needed
• Methods give direct CO2 emissions
• More default methods and direct Greenhouse Gases
• Categories simplified and clarified with IPPU and
  AFOLU
• Do not pre-empt accounting choices as all
  information is retained
• Can map back to 1996 GL plus GPG
