JODI-Gas Assessments

JODI-Gas Participation Assessment

The JODI-Gas Participation Assessment measures degree of participation in the Initiative by each  country. in three measures: timeliness, completeness, sustainability. The bi-annual assessment considers three measures: timeliness, completeness, and sustainability. 

The JODI-Gas Participation Assessment Definitions: Sustainability, Timeliness, and Completeness

Sustainability

Sustainability measures the number of JODI-Gas questionnaires received from each participating country or economy over the assessment period (six months) and within the agreed submission deadlines. A Good rating (smiley face), is earned when a country or economy submits JODI questionnaire responses for all six months in the period.

JODI-Oil Participation Assessment - Good sustainability "good" if the 6 questionnaires have been submitted

JODI-Oil Participation Assessment - Fair sustainability "fair" if 4 or 5 questionnaires have been submitted

JODI-Oil Participation Assessment - sustainability less reliable "less reliable" when less than 4 questionnaires have been submitted

Timeliness

Timeliness evaluates whether or not data has been received within two months of the end of each reference month in accordance with the data submission deadlines established by the JODI Partner Organizations. A smiley face is awarded if all six submissions within a given assessment period were received by the agreed deadlines. 

JODI-Oil Participation Assessment - Good timeliness "good" when all 6 submissions during the assessment period have been received within two months of the end of the reference month relevant to each submission

JODI-Oil Participation Assessment - Fair timeliness "fair" when 4 or 5 submissions have been received on time

JODI-Oil Participation Assessment - Timeliness less reliable "less reliable" when less than 4 submissions have been received on time

Completeness

Completeness tracks the number of data points submitted for the flows of production, imports and exports (separated into LNG and pipeline), stock changes, gross inland deliveries (observed), deliveries for electricity and heat generation, and closing stocks in volumetric units (million cubic metres at 15 degrees Celsius, and 760 mm Hg) in the JODI-Gas Questionnaire. To earn a smiley face, each country or economy must submit more than 90% of its data related to production, demand and stock changes. 

As the JODI-Gas World Database is still at an early stage of development, the assessment currently only accounts for volumetric data as it is readily available. However, a more accurate measurement of natural gas is achieved by reference to heat content value (terajoules), and the JODI Partner Organizations will continue to encourage their participating countries and economies to complete their data-sets, by also reporting in terajoules.

JODI-Oil Participation Assessment - Good Completeness "good" when more than 90% of the data are given for flows of production, imports and exports (separated into LNG and pipeline), stock changes, gross inland deliveries (observed), deliveries for electricity and heat generation, and closing stocks in volumetric units (million cubic metres at 15 degrees Celsius, and 760 mm Hg)

JODI-Oil Participation Assessment - Fair Completeness "fair" when between 60% and 90% of the data are given

JODI-Oil Participation Assessment - Completeness less reliable "less reliable" when less than 60% of the data are given

Submission Deadline

 Each JODI Partner Organization establishes its own submission deadline with their member countries and economies. The common factor is that in all cases submissions must be made no later than two months from the end of the reference month.

Data Confidence Level Assessment

The assessment was carried out on different levels:

  • Comparability of the JODI data with other sources: monthly data from national and secondary sources has been assessed.
  • JODI data have also been compared with annual data (when available) in order to check whether the levels and trend over the years could be confirmed.
  • When no other sources were available for comparison with the JODI data, internal consistency and balance check have been carried out.

Examples of internal consistency checks: the sum of all the reported products with reported figure for Total Products is compared. When both, closing and stock changes data have been submitted, the consistency of the reported changes with the calculated ones is compared.

Example of balance check : the JODI questionnaire does not collect full balance information, however some basic checks for reasonableness can be carried out e.g. supply + import - export + stock change should have a relation with demand.

Remark: for IEA /OECD countries, data in the JODI database are the MOS data for all months except data shown for M-1. Comparability for the last month has been derived from comparison with MOS data. This methodology is applied using a rolling 12 month period.

Colour Coding

  • Blue: A blue background indicates that results of the assessment show reasonable levels of comparability
  • Yellow: A yellow background indicates that the metadata should be consulted
  • White: A white background indicates that data has not been assessed
  • Purple: data under verification
