DATABASE OVERVIEW

The database is given in spreadsheet format (regional.xls) to facilitate the easy access to the database.

The database contains the following data

1.1. Energy consumption

This section specifies total energy consumption by sector and fuel type at the national level.The sectors included are Industry, Domestic (residential, commercial and agricultural), transportation, power generation, fuel conversion and non-energy use.

1.1.1 Emission factors for fuel combustion

This section specifies the fuel characteristics (such as sulfur content, calorific value, sulfur retention in ash (for coal combustion only), and emission control levels (e.g. installed FGD (Flue Gas Desulphurization) capacity on power stations) which are necessary for calculating the emission factors 

1.1.2Mobile/Line sources

Further details about fuel consumption in the transport sector will enable more precise emissions estimates. This section contains data on number of vehicles, the energy consumed and emission factors within the following vehicle categories:

1.LPG vehicles

2.Motor cycles - 2 stroke

3.Motor cycles - 4 stroke

4.gasoline cars (<1.5l)

5.gasoline cars (1.5-2.0 l)

6.gasoline cars and light trucks (>2.0l)

7.Heavy trucks - gasoline

8.Buses (gasoline)

9.Diesel cars (<1.5l)

10.Diesel cars (1.5-2.0 l)

11.Diesel cars and light trucks (>2.0 l)

12.Heavy trucks (diesel)

13.Buses (diesel)

14.Trains (coal)

15.Trains (diesel)

16.Boats/ships (diesel)

17.Boats/ships (residual fuel oil)

At the local or sub-national scale, it can be useful to collect information on the line sources like major highways, railways, inland waterways, coastal sea routes etc. The following information on the specified line source also collected:

Type of traffic, traffic volume, traffic speed, and annual vehicle kilometres traveled.

1.2 Industrial processes

These tables specify the historic activity levels (defined as annual input or output for a given industrial process/power plant) of various industrial processes which contribute to SO2 and NOx emissions (in addition to any emissions resulting from the fuel consumed which is covered under “energy consumption”). The following industrial processes are considered:

1.Paper and pulp

2.Copper smelting

3.Lead smelting

4. Zinc smelting 

5.Oil refineries

6.Sulphuric acid production

7.Nitric acid production 

8.Nitrogen fertilizer production

9.Cement production

10.Agro-processing

1.2.1. Process emission factors

This section contain information on process emission factors

1.3 Major Point Sources

This section contains information on the major point sources of emissions resulting from energy consumption (i.e. large power stations) andindustrial processes (e.g. non-ferrous metal smelters). 

The following types of data for point sources are collected: location with latitude and longitude, capacity, emission controls (and their efficiency), annual emission estimates and emission factors. 

1.4 Agricultural activities

The agricultural activities which contribute to emissions are included in this section.The following pressure variables are considered: animal population and production, and rice cultivation. 

1.5 Natural sources

In this table any natural sources contributing to the major pollutants are listed with the estimated contribution. 

1.6 Socio-economic data

There are two general types of socio-economic data given –population data and gross domestic product (GDP) data.Within these two categories, there are six specific types of socio-economic data to be collected. They are:

1.Total population, 

2.Urban population, 

3.Total GDP, 

4.Agricultural GDP, 

5.Commercial GDP, and 

6.Industrial GDP.

1.7 Total emissions

The total national emission estimates are collected on the primary pollutants.

2. State variables

The state subsystem contains measurements of ambient concentrations of air pollutants. The primary or criteria pollutants, for which data collected, are:

1.SO₂ (Sulfur dioxide),

2.NO₂ (Nitrogen dioxide),

3.PM10 (Particles with diameter < 10mm),

4.TSP (Total Suspended Particles),

5.NH₃,

6.VOCs, and

7.Wet deposition of SO₄^2- ,NO₃^- , NH₄⁺, Ca₂⁺, and

8.Dry deposition of SO₄^2- ,NO₃^- , NH₄⁺, Ca₂⁺

3. Response variables

To record the responses by Governments, Government agencies, and other responsible organizations in terms of policies and legislation enacted such as emission monitoring, environmental standards, ratification and participation in major global and/or regional conventions, etc. Environmental awareness campaigns, publicity and media use are also considered in this section.
