What is an GHG Inventory Program for?
  • Meet international obligations and expectations
  • Inform international, national, local policy
    making
  • Enhance credibility of national climate policies
    through timely, transparent, and effective
    analysis communication
  • Foster consistent estimation approaches across
    government private sector programs
  • Respond to requests for information
  • Champion for high quality objective inventory
    information

4
What is quality?
  • Transparency
  • Completeness
  • Comparability
  • Consistency
  • Accuracy
  • Transparency is the most fundamental. If you do
    not document, then there is no way to demonstrate
    any of the other principles have been met.

5
Who cares?
  • A wide audience of stakeholders...
  • Decision makers policy advisors
  • International climate change community
  • Provincial local agencies
  • The public interest groups
  • Businesses
  • Scientists

6
National government
  • Are national inventories verifiable?
  • What are current projected emissions and
    removals from key industries?
  • What are the effects of existing or planned
    policies and measures (including policies that
    aggravate emissions)?
  • Is there consensus among government agencies and
    key stakeholders on our emission estimates?
  • What are the relationships between reducing
    greenhouse gas emissions and other environmental
    pollutants?

7
International community
  • What is the your countrys contribution to global
    emissions and removals?
  • Are your GHG estimates credible and transparent?
  • Is your country meeting its UNFCCC obligations?

8
Businesses NGOs
  • How do we quantify and get credit for activities
    that reduce emissions or sequester carbon?
  • What activities, industries, companies, or
    policies have been responsible for significant
    increases or decreases in GHG emissions or
    removals?

Scientists
  • What are the priorities for research and
    measurement?
  • What are the scientific uncertainties in the
    emission and sink estimates?

Inventory management systems should...
  • Ensure inventory processes are in compliance with
    COP decisions (i.e., Non-Annex I Party National
    Communications)
  • Define and apply appropriate procedures for
    collecting, processing, communicating, and
    archiving inventory data information
  • Coordinate with relevant ministries, agencies,
    and other organizations
  • Provide inventory reports regularly
  • Ensure the quality of inventory data

11
Inventory management system
  1. Inventory planning
  2. Inventory preparation
  3. Inventory management

12
Inventory planning
  • Establish national inventory agency
  • Assign responsibilities for inventory preparation
    and management
  • Develop schedule
  • Make arrangements to collect data from
    statistical agencies, companies, industry
    associations, etc.
  • Create QA/QC plan
  • Define formal approval process within government
  • Develop review processes
  • Integrate continuous improvement

Expert and interagency review
Submit Inventory to UN
Release for public comment
14
Inventory preparation
  • Identify key categories
  • Select methods and emission factors
    (e.g., GPG decision trees)
  • Collect activity data
  • Manage recalculations
  • Implement QA/QC plan
  • Basic checks should be completed on entire
    inventory (Tier 1) (see GPG Ch. 8)
  • More in-depth investigations into key sources
    (Tier 2)
  • Documentation

15
Key categories
  • A key category has a significant influence on a
    countrys total inventory in terms of level or
    trend in emissions (GPG, Ch.7)
  • A key category may also be determined through a
    qualitative assessment.
  • A key category is one that is prioritized within
    the national inventory system
  • In general, countries should focus on key
    categories for resources and improvements

16
Inventory management
  • Implement inventory review processes (e.g.,
    expert review, public review)
  • Obtain formal approval of final results and
    report within government
  • Submit report to UNFCCC
  • Make inventory information available to
    stakeholders and respond to information requests
  • Archive all documentation and results
  • Continuous improvement feedback

17
Uncertainty
  • Uncertainty analysis is a subjective exercise, as
    it relies to a large extent on expert judgment
  • Therefore, it is not a valid basis to compare
    inventories between countries
  • Uncertainty analysis should be used as a way to
    investigate the quality of your inventory data
    and identify ways to improve data quality
  • You achieve by communicating with data suppliers
    (e.g., statistical agencies)
  • Uncertainty investigations should be integrated
    within your QA/QC plan!

18
Resources
  • IPCC Guidelines
  • Revised 1996 IPCC Guidelines
  • IPCC Good Practice Guidance
  • IPCC LULUCF GPG
  • New 2006 IPCC Guidelines
  • UNFCCC reporting guidelines
  • IPCC Emission Factor Database (EFDB)
  • IPCC software
  • NCSP booklet on "Managing the GHG inventories
    process (March 2005)

19
Other resources
  • Inventory reports from other Parties
  • UNFCCC website/GHG Data
  • www.unfccc.int
  • Inventory related reports from other Parties
  • GHG Inventory Experts Network www.ghgnetwork.org

20
Closing remarks
  • A greenhouse gas inventory is more than just a
    report. It should be viewed as an broader
    analytical program.
  • A cookbook approach to developing a GHG
    inventory is not practical. There will always be
    a large and essential need for expert judgment at
    all levels of the process.
  • A well constructed inventory should include
    enough documentation to allow readers to
    understand the underlying assumptions and to
    reconstruct the calculations.

Emission Inventory Basics
  • An emission inventory is an accounting of the
    amount of air pollutants discharged into the
    atmosphere. It is generally characterized by the
    following factors
  • The chemical or physical identity of the
    pollutants included
  • The geographic area covered
  • The institutional entities covered
  • The time period over which emissions are
    estimated
  • The types of activities that cause emissions

24
Inventory Agency Responsibilities
  • A single national entity to be responsible for
    the overall inventory
  • Arrangements with collaborating entities that
    contribute data, research, estimate emissions or
    provide expert reviews
  • Define legal authority to collect and disseminate
    data necessary for the preparation of the
    inventory
  • Ensure inventory processes are in compliance with
    COP decisions
  • Define and apply procedures for collecting data,
    preparing inventory, communicating results,
    submitting report, and archiving
  • Liaise among government departments, national
    agencies,
  • Ensure the implementation of QA/QC

25
Goals
  • Develop high quality inventory at regular
    intervals (e.g., annually, every 2-4 years, etc).
  • Resources are focused on the most significant
    emission sources in the country
