Appendix 4: Instructions on necessary information in eachdata field

IMPORTANT! - Data fields are classified into 2 categories.
<Mandatory fields> (Bolded in Table 1)
These fields must be specified since they are deemed essential in order for EFDB users toexamine the applicability of the data record to their national GHG inventories. If you submit
your data without appropriately specifying the mandatory fields, you will be prompted to fill
those fields by the EFDB or by the Technical Support Unit of the IPCC-NGGIP.
<Optional fields>
These fields can stay empty, but it is recommended for you to provide as much informationas possible also in these fields in order to facilitate EFDB users’ consideration.
Table 1 (pages 2-4) provides guidance in detail on the necessary information in each datafield.

MANDATORY FIELDS These fields will be automatically filled with the information you gave
when you registered yourself as a data provider.
 You are encouraged to show your e-mail address. If you wish,
however, you can conceal your e-mail addresses from EFDB users byremoving the tick in the checkbox. In this case, ipcc-efdb@iges.or.jp
will be shown in this field so as to enable EFDB users to contact you(the data source) via Technical Support Unit of the IPCC-NGGIP.
 This field can be left blank if the information is not available.

MANDATORY FIELD
See Appendix 5: Guidance on the “Properties” field.

Description

 “Properties” define what EFDB users might see as important
information after the categorisation stage in searching or inputting data.
 This field consists of 5 sub-fields as shown below. Necessary
information should be fully described in appropriate sub-fields.
• Technologies/Practices• Parameters/Conditions• Region/Regional Conditions• Abatement/Control Technologies• Others
 Information to be included as properties varies from one source
category to another. Detailed guidance is provided in Appendix 5.
MANDATORY FIELDValue This field should provide enough description to tell the user basicallywhat the value presented is, without being too wordy or generic.
 You should follow, to the extent possible, the terminology used in theRevised 1996 IPCC Guidelines for National Greenhouse Gas
Inventories (IPCC Guidelines) and the report on Good PracticeGuidance and Uncertainty Management in National Greenhouse Gas
Inventories (GPG2000).
MANDATORY FIELD
 Values should be precisely indicated.
 If the proposal is a range of value rather than a single value, it should
be indicated as “10 – 20” for example.
 A range of value should be distinguished from uncertainty ranges.
(Uncertainty ranges should be indicated in Upper and Lower
Confidence Limit fields.)-2-stEFDB Editorial Board

Appendix 4 of the Report of the 1 Meeting The appropriate unit should be chosen from the drop-down list. If there
is not any appropriate unit in the list, “New” button should be clicked
to type the new unit in the field.
 If the value is presented with such a unit that is not used in the IPCC
Guidelines (e.g., barrel or gallon for petroleum) in the “Value” fieldabove, you are encouraged to convert it into a value in unit commonlyused in the IPCC Guidelines (e.g., tC/TJ for Carbon Emission Factorsfor Fuels) and indicate it in this field.
 If the proposed data fit an equation presented in the IPCC Guidelines orGPG2000, the following information should be clearly indicated forusers’ convenience.
1) Equation number (if applicable)
2) Page number
3) IPCC Guidelines or GPG2000
 For example, “Equation 4.15 on Page 4.30 of the IPCC Good PracticeGuidance and Uncertainty Management in National Greenhouse Gas
Inventories”
 GPG2000 should be referenced when the same equation is presented inboth of the IPCC Guidelines and the GPG2000.
 If no IPCC equation fits, it is desirable to refer to technical reference orsource of data where equation is found and can be used.
 If the proposed data fit a worksheet of the IPCC Guidelines (Vol.2,Workbook), correct worksheet numbers should be indicated for users’convenience. (For example, “Worksheet 4-1, Sheet 1 of 2”)
 If the data are not applicable to any IPCC worksheets, then this fieldshould be “Not applicable”.
MANDATORY FIELD
 Reference should be made precisely.
 E.g, scientific literature, official national inventory reports, etc.
MANDATORY FIELD
 Technical reference should be quoted fully and precisely.
MANDATORY FIELD
 It should be indicated in which language the technical reference isavailable.
 You are encouraged to provide the abstract in English of the technicalreference in order to enable EFDB users to better understand the natureof the data.
MANDATORY FIELD
 If no information on the upper confidence limit is available,“Unknown” should be ticked.
 Do not confuse with a range of value which should be indicated in“Value” field.

1Confidence limits give the range within which the underlying value of an uncertain quantity is thought to lie
for a specified probability. This range is called the confidence interval. The IPCC Guidelines suggest the use of
a 95% confidence interval which is the interval that has a 95% probability of containing the unknown truevalue. (Chapter 6 “Quantifying Uncertainties in Practice”, GPG2000)-3-stEFDB Editorial Board

 These fields will appear only when the data provider choose“Measured” as “Type of parameter”.
 You are highly encouraged to provide appropriate information (e.g.,
description about representativeness of sampling) unless it is notavailable at all.
 In particular, clarification of the following points should be given in thefield “Measurement technique/standard”.
• Are measurement techniques/standards used comparable withnational or internationally recognised standards?
 In particular, clarification of the following points should be given in thefield “Periodicity of measurement”.
• Have measurements been made on multiple systems or sites andover sufficient time and range of conditions to capture the variabilityof emissions and to provide a stable annual average?
 Any other information relevant to the proposed data can be provided inthis field.
 For example, you are highly encouraged to provide additionaldescription of emission factor development where needed to elaborate.
 You can also provide information on further improvement need to bedone and describe what measures could be taken to improve its
accuracy and applicability.
 In the case that you have not directly consulted the original author, it
should be mentioned in this field.
 You should leave this field blank.
