1. IntroductionThe GHG Inventory in Macedonia

• Prepared for the first time as a part of the First National Communication on Climate Change,

• The three main GHGs included; time series 1990-1998• IPCC methodology used, • Key sectors: Energy, Industrial Processes, Agriculture, Land-

use Change and Forestry, and Waste. • Substantial national peer-review• Technical feedback, provided by NCSU • Mechanisms to ensure control of the quality – missing!

The GHG Inventory under the Second National Communication

• Time series 1999-2002, (according to the guidelines for the preparation of National Communications (17/CP.8))

• Inclusion of information on the other non-direct GHGs: HFCs, PFCs and SF6 as well as CO, NOx, SOx and NMVOCs.

• Revision of the input data, taking into consideration data gaps and areas needing improvement identified in the stocktaking exercise

• Identifying and developing methods for overcoming data gaps • Application of higher Tiers (more sophisticated methods) for emissions

calculation wherever possible• Inclusion of the sector Solvent and other product use into the national

inventory whenever possible (for the years when the relevant activity data are available)

• Recalculation the time series for the period 1990-1998 • Developing a full documentation of activity data and emission factors for

the year 2000• Implementation of good practice elements to maximal possible extend

2. Structure of the National GHG Inventory Team

Ministry of Environment and Physical

Planning (MoEPP),

• Supervising the national inventory process,

• International reporting the emissions.

National Institution (NI),

• Act as a National Inventory Team Leader (NITL)

• Maintain the whole GHG inventory,• Incorporate good practice elements such as

key sources analyses, uncertainty management, QA/QC procedures, documenting and archiving

• Report the emissions to MoEPP • Coordinate and supervise the Sectoral

Experts

Sectoral Experts

(two experts for each sector):

• Enterer, responsible for identification/verification of data sources, entering and documenting the input data, and

• Checker, responsible for checking and validating the input data and emission estimates.

developed under regional project “Capacity building for improving the national GHG inventory”

• Reliable data management and storage

• Precise emissions calculation

• Proper archiving and documentation

• Quality Assurance /Quality Control

• Adequate reporting

• Key sources analyses and uncertainty calculations.

I. Inventory CompilationI.1 Identification of Data Sources

Double click on “GHG INVENTORY.mdb”. You will see the following dialog:

Example I.1.1 Sector: Energy; Action: Data Sources

Instruction:

Most likely these sources will provide data for the current year. The enterer should contact the relevant institutions and assemble all relevant published documents containing activity data for the current year.

Example I.1.2

Sector: Energy; Action: No Reference

The resulting report lists all the data gaps in the corresponding sector in the previous years. Those are the data for which no reference is provided.

Instruction:

The enterer should investigate national ongoing projects and contact other experts in order to obtain the official value or proper estimate. As to the emissions factors, he should investigate whether some country-specific emission factors are derived within the ongoing national studies. Otherwise, he should follow the suit of the previous years and use the most appropriate IPCC defaults.

I. 2. Entering the Activity Data and Emission Factors

For each activity data and emissions factor data enterer should enter the following:

• Value in the specified unit

• Estimated level of the uncertainty

• Name of the person who enters the data• Complete reference to the data source.

Example I.2.1 Sector: Energy; Sub sectors: Energy Industries

By default, the form displays the first activity data and emissions factors. The browsing through all activity data and emission factors over the years is enabled by clicking on the navigation controls at the bottom of the dialog.

I.3. Calculating the EmissionsTo calculate the emissions from a given sub-sector, simply click the

action “Emissions” in the corresponding dialog.

The resulting report displays the emissions from the specified sub-sector for all years.

I.4. Validation of Input Data

Instruction 1:

This action is performed for each sector by designated sectoral expert - data checker. The data checker should check the value, unit, reference and uncertainty level entered by the data enterer, and if all is found ok, he should enter his/her name and check the validation field. Otherwise, he should report the error and propose corrective action in the filed “Comment”

By using “No Check “ action, all input data which are not validated are listed.

Instruction 2:

The two sectoral experts (enterer and checker) go together over these data and undertake corrective actions which were proposed by the checker. If the corrective action is successfully performed, they check the relevant validation field.

I.5. Validation of Emissions Estimates

Instruction:

The two sectoral experts (enterer and checker) together check the calculated emissions and perform reentering of input data and recalculation if the estimates do not meet their expectations.
