Introduction to Template 4. QA/QC Procedures

In the U.S. EPA's Templates for Creating a National GHG Inventory System Manual, this is Template 4. Its purpose is to help countries
develop a quality assurance and quality control (QA/QC) plan for current reporting under the United Nations Framework Convention
on Climate Change (UNFCCC) (i.e., Biennial Update Reports) and future required reporting under the Enhanced Transparency
Framework1 (ETF) for National GHG Inventories. It includes a series of tables in which you may record country-specific information
about QA/QC activities in order to create a QA/QC plan. It also includes three QA/QC checklists you may use to track progress of the
QA/QC work done.

The planning and implementation of QA/QC procedures are important parts of the development of national greenhouse gas
inventories. A QA/QC plan helps identify improvement options to enhance transparency, accuracy, consistency, comparability,
completeness in national GHG inventories. A QA/QC plan also builds confidence in national GHG inventories. The template can help
improve countries' understanding of elements of a QA/QC plan to improve inventory management and reporting over time.

The 2006 IPCC Guidelines have a clear and informative section on QA/QC.2 You may find it useful to read this section of the
guidelines before beginning to develop the QA/QC plan. Additional useful guidance and good practices in developing inventory
arrangements and applying QA/QC that complement this Toolkit are also provided in the 2019 Refinement to the 2006 IPCC
Guidelines.3

guidance for National Greenhouse Gas Inventory Report (available at http://unfccc.int/decisions). If you have capacity constraints related to developing a
QA/QC plan, this template may help address constraints and facilitate steps towards preparing a QA/QC plan consistent with future reporting requirements
and the 2006 IPCC guidelines.

To complete this template, the National Inventory Coordinator (NIC) and
QA/QC Coordinator should carry out the steps enumerated below by
following the instructions above each table in this template, with support
from other key inventory team members as required.

When the tables are complete, delete the green
text throughout this template. You may use the
remaining text or tables for reporting or for your
National GHG Inventory System Manual.

Purpose

1.	Convene a QA/QC Plan launch meeting and
identify QA/QC personnel

2.	Develop a timeline for distributing the
QA/QC plan amongst the inventory team
and external experts, considering the
overall inventory schedule created in
Template 1. How to Use the Templates

3.	Establish general QC procedures for
source/sink category leads to follow,

4.	Establish category-specific QC procedures
for source/sink category leads to follow

5.	Document recommendations received as a
result of experts' QA activities

6.	Propose GHG inventory improvements as a
result of QA/QC activities

7.	QA/QC Checklists

It is important to assign roles and responsibilities, so people understand their duties. For countries with
small inventory teams, one or more people may have multiple roles.

All stakeholders need to understand the importance of the QA/QC Plan and how it links to the inventory
improvement plan. This will help maximize engagement.

These are crosscutting procedures that apply to the whole of the GHG inventory and aim to improve
general quality.

These are category or sector specific procedures that focus on improving quality for specific categories,
starting with key categories.

QA procedures are carried out by experts who are not part of the core GHG inventory team but who
have considerable inventory expertise. Their experience and insight should help improve the quality of
the inventory.

This is a vital step. The areas of inventory improvement that are identified throughout the
implementation of QA/QC activities should be added the GHG inventory improvement plan. Prioritizing
the improvement activities should thus result in incremental improvements to the GHG inventory.

These checklists can help keep track of the QA/QC work done, and the work which remains to be done.

Quality Assurance/Quality Control (QA/QC) Procedures

This section explains how to compile an effective QA/QC plan. It is important to understand the basic principles before developing
and implementing a QA/QC plan.

Background

Quality control and quality assurance measures are two distinct types of activities. The IPCC defines them as follows:

•	Quality Control (QC) - A system of routine technical activities implemented by the inventory compilers to measure and
control the quality of the inventory as it is prepared.

•	Quality Assurance (QA) - A planned system of review procedures conducted by personnel not involved in the inventory
development process. QA procedures are performed upon a completed inventory following the implementation of QC
procedures and preferably by independent third parties. A basic expert peer review is part of this process.

•	Verification - The activities and procedures conducted during the planning and development, or after completion of an
inventory that can help to establish its reliability for the intended applications of the inventory. For inventories, verification
refers specifically to those methods that are external to the inventory and apply independent data, including comparisons
with inventory estimates made by other bodies or through alternative methods.

This means that QC is part of the inventory compiler's day-to-day work. In contrast, external staff who are not involved in the
inventory compilation perform QA as an additional quality check. Verification activities may be constituents of both QA and QC,
depending on the methods used and the stage at which independent information is used.

QC is further divided into general and category-specific QC procedures. General QC procedures include generic quality checks
related to calculations, data processing, completeness, and documentation that are applicable to all inventory source and sink
categories. Category-specific QC procedures complement general inventory QC procedures. Category-specific QC is directed at
specific types of data used in the methods for individual source or sink categories. These procedures require knowledge of the
specific category, the types of data available, and the parameters associated with emissions or removals, and are performed in
addition to the general QC checks.

QA/QC - 4

Updated June 2021


-------
QA and QC are critical components of an inventory management system because when they are implemented effectively, they drive
inventory improvement. Therefore, a fundamental element of the inventory management system is a written QA/QC plan. This plan
outlines QA/QC activities to be performed, the personnel responsible for these activities, the schedule for completing these
activities, and a list of future planned QA/QC improvements. An effective QA/QC plan includes the following elements:

•	Personnel responsible for coordinating QA/QC activities;

•	General QC procedures;

•	Category-specific QC procedures;

•	QA review procedures;

•	Reporting, documentation, and archiving procedures; and,

•	A prioritized QA/QC improvement list, which should be reviewed regularly and used to guide improvements.

An initial step towards developing a QA/QC Plan is to appoint one person to be the QA/QC coordinator. This is the main person
responsible for developing, maintaining and implementing the QA/QC plan. Ideally, this person will be knowledgeable about each
sector of the GHG inventory in order to understand the implications of ensuring quality in each of the sectors. If the inventory team
is small, it is possible for one or more people to may have multiple roles. A large QA/QC team is not a necessity - the key is to ensure
that the QA/QC system is efficient and effective and helps drive inventory improvement.

The QA/QC Coordinator should develop the QA/QC plan with input from each of the sector leads and ensure each receives the final
plan. The QA/QC Coordinator should also regularly review the plan and modify it to reflect new processes, implement recommended
improvements, or support the objectives of the National Inventory Improvement Plan. This is particularly important to do at the
start of each GHG inventory compilation cycle. Related to this, the QA/QC Coordinator should keep records about how
improvements have been implemented, and what their effects have been.

STEP 1. Convene a QA/QC Plan launch meeting and identify QA/QC personnel

•	Convene a meeting with all team members to initiate the development of the QA/QC plan. Identify the people that could be
involved in the plan. The plan should apply to the whole team (including consultants, universities, etc.) that is involved in the
estimation and reporting of the GHG inventory.

QA/QC - 5

Updated June 2021


-------
•	Identify the QA/QC coordinator. This is the main person responsible for developing, maintaining, and implementing the

QA/QC plan. In this role, the QA/QC coordinator:

o Clarifies and communicates QA/QC responsibilities to inventory members.

o Develops and periodically reviews and updates the QA/QC checklists appropriate to various inventory team member roles
(or ensures that these tasks are accomplished). (See Table 4-3 and Table 4-4 for examples).

o Determines an overall QA/QC timeline and when external reviews will occur, and ensures the timely and accurate
completion of QA/QC checklists and related activities.

o Manages and delivers documentation of QA/QC activities to the NIC and archive coordinator.

o Coordinates external reviews of the inventory document and ensures that comments are incorporated into the inventory.

•	Identify key QA/QC personnel and any additional country-specific QA/QC responsibilities.

•	Complete Table 4-1 below with the names and contact information of the appropriate staff.

o Insert as many rows within the table as necessary to include all personnel who will be responsible for QA/QC activities,
and all QA/QC responsibilities.

o The responsibilities associated with each of the roles are suggested in the "QA/QC responsibility" field. You may
modify them as needed.

o Note that the roles are flexible and may overlap. Therefore, one staff member might cover a large number of
categories or even cover a whole sector. Inventory staff may have a joint inventory compilation-QA/QC role. It is
unnecessary to limit one person's role to coordinating inventory QA/QC.

o It is important that QA/QC efforts be focused on key categories but are applied to the whole GHG inventory; Template
5 explains how to identify key categories.

STEP 2. Develop a timeline for distributing the QA/QC plan amongst the inventory team and external experts

• It is essential to communicate the contents of the QA/QC plan to inventory team members and outside experts involved in
quality assurance of the GHG inventory so that the procedures can be effectively implemented, evaluated, and improved. The
QA/QC coordinator should develop a timeline for taking the following actions:

o Creating or updating the QA/QC plan

o Participating in an inventory inception meeting with all of those working on the inventory (including consultants,
universities, etc.), and at the meeting, introducing the plan to all team members required to perform QA/QC, and
distributing QC checklists (see National GHG Inventory Inception Memorandum supporting template)

o Checking that members of the inventory team understand the purpose and outcomes of the QA/QC plan, and updating
the plan to address any questions

-------
o Periodically reminding team members of their QA/QC responsibilities and the overall QA/QC schedule

STEP 3. Establish general QC procedures for source/sink category leads to follow

•	To develop the QA/QC plan, gather existing QA/QC procedures. Include QA/QC procedures used by data providers. These
procedures can then be strengthened if necessary.

•	The first part of developing the QA/QC Plan is to establish general QC procedures. These include generic quality checks related
to calculations, data processing, completeness, and documentation that are applicable to all inventory source and sink
categories and should be implemented each year. A minimum set ofQC procedures should be followed each year for all
categories to ensure that basic standards of quality are met. These standards generally focus on the processing, handling,
documenting, archiving, and reporting procedures common to all categories.

•	Table 4-3, below, lists the QC activities that should be performed at the category or subcategory level by staff compiling these
estimates.

o The Procedures column includes a description of tasks that could be done as part of each QC activity. It is not necessary to
complete all of these tasks, but you are encouraged to ensure that as many of them as possible are completed. Volume 1,
Chapter 6.6 of the 2006IPCC Guidelines provides further useful guidance.

Updated June 2021


-------
o Modify these activities and their associated procedures as needed, and add as many rows as necessary,
o For each procedure, record the name of the person responsible for the item and the date of completion.4

According to the 2006 IPCC Guidelines, though general QC procedures are designed to be implemented routinely for all
categories, it may not be necessary or possible to check all aspects of inventory input data, parameters, or calculations every
year. Instead, you may apply general QC procedures to a representative sample of data and calculations each year. In
establishing criteria and processes for selecting sample data sets and processes, it is good practice for the inventory compiler to
undertake QC checks on all parts of the inventory over an appropriate period as determined in the QA/QC plan.

STEP 4. Category-specific QC procedures for source/sink category leads to follow

Category-specific QC complements general inventory QC procedures. Category-specific QC focuses on specific types of data used in
the methods for individual source or sink categories. These procedures require category-specific knowledge, and knowledge of the
types of data available and parameters associated with emissions or removals. For future UNFCCC reporting, countries should apply
category-specific QC procedures for key categories (See Template 5. Key Category Analysis) and for those individual categories in
which significant methodological changes and/or data revisions have occurred in accordance with the 2006IPCC guidelines and as
resources allow.

• Table 4-4, below, lists the category-specific QC procedures that should be performed.

o E.g., if based on measurement studies, did

measurement program included QC procedures
o E.g., understand characteristics of data (e.g.
completeness, etc.)

•	Assess whether secondary studies used to develop
country-specific factors used (at a minimum)
general QC activities.

•	Compare country-specific factors to IPCC defaults;
document any significant discrepancies.

•	Compare country-specific factors to site or plant-
level factors.

•	Compare to factors from other countries (using
UNFCCC review tools, reported factors in inventory
submissions, and/or IPCC Emission Factor
Database).

•	Conduct reference calculations that use
stoichiometric ratios and conservation of mass and
land.

•	Document results of this assessment.









Review

measurements

•	Determine if national or international (e.g., ISO)
standards were used in measurements.

•	Ensure measurement equipment is calibrated and
maintained properly.

•	Compare direct measurements with IPCC or other
published default factors; document any significant
discrepancies.









Activity Data QC

QA/QC -17

Updated June 2021


-------
Review national-level
activity data

•	Determine the level of QC performed by the data
collection agency. If inadequate, consider
alternative data sources such as IPCC defaults and
international activity data sets (e.g., IEA, FAO).
Adjust the relevant uncertainty accordingly.

•	Compare activity data from multiple references
(e.g., other independently compiled data) if possible
(e.g., IEA, FAO, etc.), including data time series









Review site-specific
activity data

•	Determine if national or international (e.g., ISO)
standards were used in collecting or generating
data.

•	Compare aggregated site-specific data (e.g.,
production) to national statistics/data.

•	Compare data across similar sites.

•	Compare top-down and bottom-up estimates for
similar orders of magnitude.









Trend checks of
activity data

• Compare data to previous year's data and review
any sharp increases or decreases,
o If national activity data for any year diverge
greatly from the historical trend, they should be
checked for errors,
o If a calculation error is not detected, the reason
for the sharp change in activity should be
confirmed and documented.









QC uncertainty
estimates

•	Apply QC techniques to uncertainty estimates.

•	Review uncertainty calculations.

•	Document uncertainty assumptions and
qualifications of any experts consulted.

GHG Estimate QC/Verification

QA/QC-18

Updated June 2021


-------
Verify GHG estimates

•	Compare estimates to other independently
compiled national estimates as available.

•	If using higher-tier methods or models, apply lower-
tier methods (e.g., Energy sector comparison of
reference and sectoral approach).

•	Compare intensity indicators between countries

•	Document, report, and archive verification findings
and any further actions (e.g., additional QC,
improvement plans).









STEP 5. Document recommendations received as a result of experts' QA activities

•	Quality Assurance involves expert reviewers not involved in preparing the inventory, and a basic peer review process. QA
activities follow QC activities and complement QC activities.

•	Expert review offers the opportunity to uncover technical issues related to the application of methodologies, selection of
activity data, and development and choice of emission factors. The comments of the expert reviewers should be reviewed and
addressed, as appropriate, prior to the submission of the Inventory, and documented/archived appropriately to ensure
transparency and for reference of future compilation teams.

•	Experts should be independent of the inventory agency, and affiliated with other national agencies, research facilities,
international organizations, or other organizations with relevant expertise in GHG emission estimation methodologies,
activity data, or other parameters. If third party reviewers are unavailable, staff from another part of the inventory agency
not involved in the portion of the inventory under review can fulfill this role.

•	Key categories (as outlined in Template 5) should be given priority for review, as well as source categories where significant
changes in methodology or data have been made.

•	The annex to this template provides a template you may use to instruct external reviewers (i.e., for expert elicitation).

•	Using Table 4-5, below, identify the experts who are reviewing the GHG inventory. In the Comment Summary column,
summarize experts' recommendations regarding specific improvements that could be made to the GHG inventory as a result

SUBJECT: Expert Review Process for [insert starting year of time series] - [insert last year of time series]
Draft Inventory of [insert the name of your country]'s Greenhouse Gas Emissions and Removals

Introduction

Thank you for your interest in providing input during the expert review process of the [insert starting
year of time series] - [insert last year of time series] Draft Inventory of [insert the name of your
country]'s Greenhouse Gas Emissions and Removals. Per the email [insert email address used or name
of staff member who sent the email] previously sent you on [insert date of email] regarding the targeted
approach for this year's expert review process, you have been identified as an expert who may wish to
submit comments on this early draft of the [insert sector(s) or categories to be reviewed]. Please note
that the deadline for submitting comments is [insert the deadline by which review comments should be
submitted].

To facilitate your review and indicate where input would be helpful, this year's expert review includes
charge questions. While these charge questions are designed to assist both reviewers and the inventory
team in conducting a more targeted expert review, comments outside of the charge questions are also
welcome.

Categories to be reviewed

[In case not all categories included in the report are ready for review, clarify which categories are to be
reviewed, ideally in the form of a bulleted list or table]

Relevant Updates

[Where relevant methodological updates have been applied to any categories to be reviewed, list these
and clarify what the main updates are in the following format:

•	Category Code - Category Name - Change (e.g. new category included, moved to tier 2
approach for activity data)

•	Example: 2.B.4 - Caprolactam, Glyoxal and Glyoxylic Acid Production - New source category
included in draft 1990-2016 Inventory (emissions from this category range from 1.6 to 2.2 MMT
C02e across the time-series). ]
