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
3
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.
4
Who cares?
▪ A wide audience of stakeholders...
▪ Decision makers & policy advisors
▪ International climate change community
▪ Provincial & local agencies
▪ The public & interest groups
▪ Businesses
▪ Scientists
5
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?
6
International community
▪ What is the your country’s contribution to
global emissions and removals?
▪ Are your GHG estimates credible and
transparent?
▪ Is your country meeting its UNFCCC
obligations?
7
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
10
Inventory management system
1. Inventory planning
2. Inventory preparation
3. Inventory management
11
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

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
14
Key categories
▪ A key category has a significant influence on a
country’s 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
15
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
16
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!

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
23
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
24
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
