What’s the situation with the Guidebook
today
•
•
•
•
•
•
2
Contains most influential set of emission estimation
methods for air pollutants in Europe
Essential reference for reporting under both CLRTAP
(and its protocols) and the NEC Directive
Some gaps in available information e.g. sector &
pollutant combinations
Some other information needs updating
Inconsistencies in method description between
chapters
Little guidance on methodological choice and on good
practice

A complete and coherent Guidebook essential for
future scientific work, trust among stakeholders and
compliance checking of both the NEC Directive and the
Convention and its protocols
European Commission asked EEA to prepare a
Guidebook update and restructuring plan and indicated
its intention to financially support it
EEA prepared such a plan together with the chair of
the EMEP SB, the TFEIP chair (representing also the
CLRTAP secretariat) and the European Commission
European Commission is about to choose the
consultants that will support the execution of the plan
It is this plan that is presented here for discussion
Input from this discussion will be used in steering the
consultant’s work
Underlying principles
• Guidebook intended main users
• Experts responsible for preparing national
air pollutant emission inventories to be
reported under both CLRTAP (and its
protocols) and the NEC Directive
• Guidebook objectives
• Support compliance with reporting
obligations under CLRTAP and NEC
• Support inventory improvement process

What would the Guidebook include?

5
Complete source descriptions
Guidance on good practice aspects such as key source
analyses, QA/QC systems, uncertainty management
and projections
Guidance on methodological choice (incl. decision
trees)
Tier 1 methods for all pollutants from all sources
Tier 2 methods for potential key sources
Tier 3 methods for particularly important methods or
methods already included in the Guidebook
Emission factors, both default and technology
dependant values for a range of process conditions
and abatement technologies that might occur in
different countries
Uncertainty estimates for emission factors
How to restructure?
•
•
•
•
•
6
Follow IPCC guidelines as close as possible
while respecting particularities of air pollutant
inventories
Table of content to follow NFR for source
categories
Retain link to SNAP classification as process
based sub-categories
General chapter on how to estimate spatially
disaggregated emission data in the cross
cutting issues section and/or in source
category chapters
Separate as far as possible numerical
information from the main text (stable
information)
Guidebook components

Emission Factor
Database?
Why have, or not, an emission factor
database?
•
•
•
Reduces data ambiguity and data omissions
More efficient and better data QA/QC
Easier to find what you are looking for
•
•
Can require intensive resourcing
May take more time for experts to supply the
data / Data suppliers need to be trained
Will the data suppliers choose to use the
database?
•
8
What role, if any, to an emission factor
database
•
•
•
9
Option A: No database
Option B: Database contains all numerical
values of emission factors contained in the
Guidebook [Static database of only data
in the Guidebook]
Option C: Option B + database contains new
data and information approved by TFEIP and
expert panels [Living database continually
updated with new information]
How to organise the work
• The final responsibility for the
technical content of the
Guidebook lies with the TFEIP
• The practical restructuring and
update work will be done by the
consultants

expert panels to discuss and draft relevant sections of the
GB and with AEG to discuss progress of work

revised draft version
June 08 TFEIP recommends to EMEP SB approval of new GB
Sept 08 EMEP SB recommends to UNECE EB endorsement of
new GB
Dec 08 UNECE EB endorses new GB
