National emission inventory system SNIEPA
(Système National dInventaire des Emissions de
Polluants dans lAtmosphère)
The single national inventory system covers all
national air emission inventories (ie for UN and
EC purposes) and other national needs The
Ministry of Ecology and Sustainable Development
(MEDD) is the national authority responsible for
managing this issue CITEPA is responsible for
inventory compilation for all source categories,
technical discussion with international
organisations, assists the MEDD in coordinating
activities, provides facilities for dissemination
(Internet) More details on National emission
inventory system and methodologies http//www.cite
pa.org/publications/Inventaires.htminv6
Various ministries and organisations (technical
and research centres, statistics institutes,
professional organisations, etc.) are also
involved as data providers Institutional
arrangements are still under discussion to fulfil
EC and UNFCCC decisions

Overview of main features of QA/QC plan

• Inventory compilation based on processus and
  procedures driven by a quality management system
  (QMS)
• QA/QC is operational and implemented through a
  QMS (CITEPA is certified ISO 9001 version 2000
  for emission inventories)
• The QA/QC plan focuses on improvements on an
  ongoing basis, especially by reducing
  uncertainties, by covering more substances, both
  in a convenient and efficient way
• QA/QC plan developped according to QMS rules (ISO
  9001) and includes sections on
• quality objectives,
• quality control,
• quality assurance,
• overview of process, procedures and recording
  related to GPG
• Documentation, archiving stringent requirements
  in QMS to trace all information (including
  origin, primary data, assumptions, etc.) and all
  intermediate and final results

Quality control
QC procedures are applied to all input data
including those provided by statistics
institutes or administrations Priority is
focussed on non validated data vs official data
Checks on input data enables a high level of
reliability more than an accurate assessment of
absolute values Common QC procedures compatible
with IPCC good practices are applied to the
different stages in the processes

• Example
• documentation, assumptions, primary calculations
  are compiled
• within methodology files
• the national inventory system includes
  approximatively 140 files
• which cover the SNAP activities (some files
  deal with several SNAP
• codes).
• Some data (activity rates, emission factors, etc.
  are common to
• several files. Mapping these files makes it
  possible to check
• interlinked consistency

Quality control

• IPCC Tier 1 requirements implemented through QMS
  procedures
• QC checks conducted by CITEPA and upstream
  compilation by statistics offices,
  administrations, etc. and by some experts
  depending on data and priorities (key sources)
• Annual process cycle based on automatic and
  manual procedures
• Examples of main check types Main methods
• Plausibility, reference range
• Exhaustivity of data (activity rates, check
  list
• emission factors, documentation, etc.)
• Accuracy of calculation simulation
• Comparability of estimation methods analysis
  and reference
• with guidelines (UNFCCC, IPCC, EMEP/
• CORINAIR, EC, WBCSD, etc.)
• Trends in activity rates, emission analysis,
  statistical
• factors, emissions treatment
• Consistency cross-checking

Quality assurance
Procedures in place CCIIE (Coordination and
Information Committee on Emission Inventories)
international review (UNFCCC) external experts
(for some activities) Other complete external
reviews are expected but not yet implemented
because of resources needed but not available

• An action plan is progressively drawn up over
  time from
• decisions taken at recent CCIIE meetings,
• events occurring during the current year,
• changes and improvements following remarks from
  reviews, errors,
• new information available
• and approved / delayed / rejected by the CCIIE
• Every year, final statement by early December
  (data sent before
• 31st December N1, reports available within
  January / March N2

Inventory development
Goals satisfy terms of reference including
specifications such as UNFCCC guidelines and GPG,
EC recommandations QMS procedures are applied to
continuously improve the inventory (and the
system)

• CURRENT PERCENTAGE OF TIER LEVELS (ABSOLUTE LEVEL
  2003)
• 90 of 42 key sources are estimated from Tier 2
  or more
• methods
• 82 of key sources emission are estimated from
  Tier 2 or
• more methods

• CURRENT PERCENTAGE OF TIER LEVELS (TREND 1990
  2003)
• 90 of 54 key sources are estimated from Tier 2
  methods or
• more
• 93 of key sources contribution are estimated
  from Tier 2
• methods or more

Inventory development - improvements 1 / 3

• Identification of improvement areas
• Topics previously delayed,
• Feedback from UNFCCC ERT and EU GHG MM checks,
• Feedback from inventory compilers (ie. checks),
• Feedback from inventory users,
• Feedback from non GHG inventories (verification
  and use) This input can be valuable by
  pointing out problems affecting as well relevant
  items for GHG inventories -gt strong interest
  for a single inventory system
• All feedbacks pointing out problems are
  registered within the QMS (CITEPA is certified
  ISO 9001 version 2000 for emission inventories)

• Postponed actions,
• Rejection

• 5. Implementation
• According to decision (content and delay)

Respond to ERT comments

• Differents steps
• Arrange availability of experts to respond during
  the review period,
• Provide explanations as quickly as possible (high
  priority),
• Treat ERT comments as feedback in the improvement
  process for the next inventory release,
• ERT review report is carefully analysed,
• Response is provided to UNFCCC through official
  authority,
• Communication to EC for EU inventory reporting
