The 2006 IPCC Guidelines

1
The 2006 IPCC Guidelines

• Simon Eggleston
• Head, Technical Support Unit for the IPCC
  National Greenhouse Gas Inventories Programme

2
Note

• Production of new guidelines is still at an early
  stage (due 2006)
• Guidelines still need to be compiled and reviewed
• So cannot state definitively contents of new
  guidelines
• Can indicate areas where changes or additions are
  anticipated
• We will introduce issues that have arisen while
  drafting the volumes

3
The Existing IPCC Guidelines

• Comprise three parts
• Revised 1996 IPCC Guidelines For National
  Greenhouse Gas Inventories
• Good Practice Guidance and Uncertainty Management
  in National Greenhouse Gas Inventories (GPG 2000)
• Good Practice Guidance for Land Use, Land-Use
  Change and Forestry (GPG2003)

4
Guidelines have been very successful.

• The approach provides options for all countries.
• There are methods for almost all source and sink
  categories.
• The IPCC created standardized reporting tables
• Successfully standardized source sink category
  definitions, units, classifications, and
  reporting techniques
• Have become the standard reference for
  inventories
• Have played a critical role in furthering the
  goals of the UNFCCC.

5
IPCC Good Practice Guidance

• Framework for prioritizing resources through
  guidance on methodological choice and key
  category analysis
• Guidance on QA/QC, quantitative uncertainty
  analysis, methodological choice, reporting and
  documentation, time series and consistency
• LULUCF change from activity-based to land
  use-based accounting system
• New guidance on land classification, Kyoto
  accounting, additional categories
• New reporting structure and tables

6
However

• Basis of Guidelines now 10 years old
• New information, scientific and technical
  advances have appeared
• Further sources have been identified or have
  arisen
• Time for a complete revision of the guidelines

7
Mandate

• SBSTA17 invited the IPCC to revise the Revised
  1996 IPCC Guidelines for National Greenhouse Gas
  Inventories, taking into consideration the
  relevant work under the Convention and the Kyoto
  Protocol, and to aim to complete the work by
  early 2006.
• In response to the SBSTA request, IPCC agreed the
  terms of reference and outline of the work at
  IPCC XXI in late 2003.

8
2006 Guidelines

• Will be based on
• the existing Guidelines and Good Practice
  Guidance reports
• Emission Factor Database (EFDB)
• Advances in science and technology
• The experience in the use of GLs/GPGs as well as
  experience from UNFCCC inventory reviews
  (e.g.FCCC/SBSTA/2003/INF.10)
• A key principle will be to approach the revision
  with flexibility but to maintain the existing
  structure as much as possible to facilitate the
  job of inventory preparers (evolution not
  revolution)

9
2006 Guidelines 5 Volumes

• Contents
• Overview
• Cross-cutting Issues, and Reporting Tables
• Energy
• Industrial Processes and Product Use (IPPU)
• Agriculture, Forestry and Other Land Use (AFOLU)
• Waste

10
Volume 1 Cross-cutting topics

• Revised and consistent general guidance on
• QA/QC,
• Quantitative uncertainty analysis,
• Methodological choice,
• Data selection,
• Reporting and documentation,
• Time series and consistency
• NEW recommendation for key category analysis
  level of assessment

11
Volume 2 Energy

• Methods for most sources are well developed from
  the 1996 Guidelines and Good Practice
• Some important issues
• Treatment of energy use of fossil fuel,
• Accounting for atmospheric oxidation of CH4,
  NMVOCs, and CO (e.g., fugitive CH4 from coal
  mining, oil gas)
• Capture and storage of CO2
• Abandoned coal mines
• Aviation and marine emissions

12
Volume 3 IPPU

• Merging of Industrial Processes and Solvents
  chapters from the 1996 Guidelines
• Significant development on F-gases
• Areas for new work
• Flat-panel display
• Broader coverage of mineral and chemical industry

13
Volume 4 AFOLU

• New structure merges Agriculture and LUCF to
  resolve inconsistencies and avoid double
  counting/omissions.
• Builds on the work of GPG 2000 and GPG 2003,
  particularly the shift to consistent land
  classification approach
• Countries have had very little experience with
  LUCF GPG
• General need to streamline the guidance in LUCF
  GPG

14
Volume 5 Waste

• No major restructuring necessary
• Areas for further development/new methods
• Improvement of emission factors for developing
  countries
• Methodological work on accounting for reductions
  in CH4 from landfills
• Development of improved Default method for
  Landfill sites

15
2006 Guidelines - Gases

• Current coverage
• CO2, CH4, N2O, HFCs, PFCs and SF6 (direct GHGs)
• NOx, CO and NMVOC and SO2 (indirect GHG
  precursors)
• New gases identified in the IPCC TAR will be
  included if they meet following criteria
• GWP Available
• Anthropogenic sources identified
• Basis for methodological development
• Relative importance total emissions

16
Precursors Indirect GHG

• NOx, CO and NMVOC and SO2
• A need for development for New methods for ozone
  precursors is not anticipated as these are
  addressed under other agreements and conventions.
  
• Users referred to other guidance

17
2006 Guidelines New Sources

• New Sources will be included if the following
  criteria are met
• Basis for methodological development including
  the ability to develop default emission factors
  exists
• It is feasible to obtain the necessary data to
  implement the method
• The source is significant within the sector.

Conclusions

• Writing is still continuing - First Order Draft
  nearly finished due January 2005
• Review not undertaken yet - So cannot be
  definitive on any changes in guidelines
• However many improvements identified
• Guidelines to target for delivery in 2006
