9. Description of sources Graphical diagram: source and emissions
Are these block diagrams useful?

10. Methods Decision tree The decision tree Supports methodological choice
Leads to the best method, depending on
Available data
Key source or not
Harmonizes with IPCC
Tinus Pulles & Jeroen Kuenen
24/02/2019

11. Methods Tier 1: the algorithm
Simplest method
Production statistics
In this case: cement production
One default emission factor per pollutant covers all sub-processes
Material to check IEFs against?
IEFs at this level
Tier 1 default values need an uncertanity range
Tinus Pulles & Jeroen Kuenen
24/02/2019

12. Methods Tier 1: default emission factors
Standardized table
Header defining source category and fuel
Fuel: not applicable here
Process emissions
Combustion emissions included elsewhere
Tinus Pulles & Jeroen Kuenen
24/02/2019

13. Methods Tier 2: the algorithm
Two approaches
Stratify technologies and abatement
Develop country specific emission factors
Tinus Pulles & Jeroen Kuenen
24/02/2019

14. Methods Tier 2: technology dependent EFs and abatement
Two types of technologies:
Process techniques
Technology Specific EFs
Add on abatement technology
Abatement efficiencies
Tinus Pulles & Jeroen Kuenen
24/02/2019

15. Methods Tier 2: technology dependent emission factors
Standardized tables
Technology dependent emission factors
Header defining source category and fuel
Fuel: not applicable here
Technology
Four “properties”
Geography
Abatement
Other
(See IPCC EFDB)

16. Methods Tier 3: process modelling and/or facility level data
Detailed process modelling
Not available for Cement production
Example: COPERT for road transport
Using facility level data
National facility level emission reports
E-PRTR facility data or EPER data
European Emission Trading Scheme (EU ETS)

18. Cross Cutting Issues Only if source category specific issues shop up
Reference to BREF documents
Verification

19. Emission Factors from the Guidebook (2006 version) The pilot TFEIP EFDB is used
Total of emission factors extracted from the Guidebook
87% is from Combustion (1.A, excluding 1.A.3)
7.5% is from Industrial Processes (2)
Added to TFEIP EFDB:
entries for Road Transport (source: COPERT)
3 024 entries for Particulates (source: CEPMEIP)
Total of emission factors in TFEIP EFDB
The team works in a copy of this

20. Emission Factors from the Guidebook (2006 version) The pilot TFEIP EFDB is used
Not included (yet):
07 Road Transport
10 Agriculture
Detail tables with Tier 3 estimates in:
Small Combustion
Aircraft emissions
Information extracted:
NFR, SNAP, pollutant, value, upper/lower limits
Information on process, techniques, control and other properties
Full reference to Guidebook and original source

21. Emission Factors from the Guidebook (2006 version) Problems
Difficulties in relating every single emission factor to a NFR sector:
the latest NFR is more detailed
processes combined in one emission factor
Guidebook emission factors less specific than NFR
Error and missing specs in the current Guidebook, such as wrong or missing units, missing references, etcetera.
Obvious errors corrected
Remarks noted as “Comments from Data Provider”

22. Emission Factors from the Guidebook (2006 version) Overlap Combustion - Processes
Industrial Processes also include combustion (e.g. cement). One EF represents combustion and process.
Process chapters also include combustion, and vice versa.
Combustion (1.A) ánd process (2) NFR in chapter heading
Only one NFR in chapter heading. (Example on next slide)

23. Emission Factors from the Guidebook (2006 version) Example

24. Emission Factors from the Guidebook (2006 version) Frequency distribution of emission factors
Range in emission factors for one sector and one pollutant
Example: NOX in 1.A.1.a (total of 1195 emission factors)
Range g/GJ; Geometric mean (solids) = 164 g/GJ

25. Next steps and further developments
Drafting the pilot chapter on Cement identifies a number of issues that need to be solved
Expert panels and experts to comment on these issues by end of June
Interpretation of NFR (combustion and process emissions)
Process block diagrams
Interpretation of Tiers
Standard tables
Using available methods in the present Guidebook
Expert panels to comment on the proposed approach
The team will draft sectoral chapters over summer
Discuss these chapters with EP in workshops, starting August, ending December
Define additional work to be done to solve any problems and gaps
Issue contracts with experts to perform this work.
