INTERGOVERNMENTAL PANEL ON CLIMATE CHANGE
IPCC/OECD/IEA Programme for
National Greenhouse Gas Inventories

Questionnaire on the Assessment of National Feedbackon the Revised 1996 IPCC Guidelines for
National Greenhouse Gas Inventories

June 1998

Purpose
The purpose of this questionnaire is to identify the difficulties countries may encounter in theapplication of the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories (IPCC
Guidelines).

Who should fill in this questionnaire?
This questionnaire should be filled out by technical contacts preparing national greenhouse gas

F. Tables
Instructions for Filling in the Following Tables
Please read these instructions carefully before you fill out the tables.
•

The Tables cover the six IPCC modules: Energy, Industrial Processes, Solvent and Other
Product Use, Agriculture, Land-use Change and Forestry, and Waste. Fill out the tables byusing the codes provided at the top of each column. The content of each column is briefly
described below.

•

The Source Categories, as provided in the IPCC Guidelines, are indicated in Column 1. Use
additional rows if further disaggregation is needed.

•

The Gases for which information is requested are indicated in Column 2. Use additional rows if
further disaggregation is needed.

•

The Status Column should indicate the status of the emission estimates in your latest
inventory.

•

The Method Column should indicate whether you have used an IPCC method or a countryspecific method. If you have used an IPCC method, indicate which tier was applied. This is only
applicable in those cases where more than one default method is provided in the IPCC
Guidelines.

•

The Activity Data Column should indicate the source of the activity data used in your national
inventory.

•

The Emission Factors Column should indicate the source of the emission factors used in yournational inventory.

•

The Difficulty Column should indicate the level of difficulty for obtaining the emission
estimates. For example, an estimate might be considered to have a high level of difficulty if theactivity data were not available and a special project was carried out to obtain these data.

•

The Priority Column should indicate where most efforts are needed to improve the quality ofthe estimate for a particular source. For example, if a source is a large contributer to nationalemissions, but the activity data or emission factors are low quality, it would rank as a highpriority.

Note: You may wish to describe problems on methods, activity data or emission factors bysource and gas not addressed in Sections B and C of the questionnaire. In this case, please
report them at the end of this section. Make sure you clearly identify the source and gas foreach of your comments.
