ASSESSING GREENHOUSE GAS EMISSIONS:
(considering only production processes)

1. Use of Power or Electricity

Compare the carbon dioxide emissions from power or electricity used in the production process of each product and service in the present year (with 12 months data), with the carbon dioxide emissions in 2002. The greenhouse gas emission factor of the electricity generation in Thailand is calculated and concluded in a study report by Thailand Greenhouse Gas Management Organization (Public Organization), (greenhouse gas emission factor is 0.5812 kgCO₂e / kWh for 2009).

2. Use of Fossil Fuel in the Production and Transport Within Industrial Plant

Compare the carbon dioxide emissions from power and electricity used in the production process of each product, generated from fossil fuel consumption, in the present year (with 12 months data), with the carbon dioxide emissions in 2002. The greenhouse gas emission factors based for each type of fuel used at a certain amount was calculated and concluded in separate study reports prioritized as the following:

1. A study report of industrial plants joining the Carbon Reduction Label Project
2. A study report of the Thai Ministry of Energy’s Department of Alternative Energy Development and Efficiency
3. A study report on “2006 IPCC Guidelines for National Greenhouse Gas Inventories” of the Intergovernmental Panel on Climate Change (IPCC)

Examples of the greenhouse gas emission factors based on each type of fuel used at a certain amount which were calculated and concluded by separate study reports of the Department of Alternative Energy Development and Efficiency and IPCC are...

3. Use of Raw Materials in Production Process

Some raw materials used in the production process for manufacturing products cause carbon dioxide emissions, such as the use of limestone in cement production. Therefore, the assessment and calculation for the amount of carbon dioxide emissions from each raw material are needed. The calculation is performed by comparing figures in the present year (with 12 months data) with the baseline data in 2002.

4. Waste and Wastewater Management

Assessing and calculating greenhouse gas emissions are performed by considering waste and wastewater management system, and amount waste and wastewater. Different types of wastes/wastewater emit different amounts of greenhouse gas emissions; therefore, system and amount of waste and wastewater related to product manufacturing and service provisioning are considered.
