Guidelines for collecting operational data for greenhouse gas inventories

Identify and collect standard data for greenhouse gas inventory

Greenhouse gas inventory process

1. Business survey - Determine inventory goals and scope

2. Identify emission activities; Collect information, documents, and records to serve quantitative inventory activities.

3. Emission quantification

4. Greenhouse gas inventory by base year

5. Greenhouse gas inventory report.

Identify sources of greenhouse gas emissions:

According to ISO 14064-1, there are 6 groups of greenhouse gas emission sources as follows:

- Group 1: Direct GHG emissions/removals / Group 1: Direct GHG emissions/removals

- Group 2: Indirect emissions/removals from imported energy / Group 2: Indirect GHG emissions/removals from imported energy.

- Group 3: Indirect emissions/removals from transportation activities / Group 3: Indirect GHG emissions/removals from transportation.

- Group 4: Indirect emissions/removals from equipment use / Group 4: Indirect GHG emissions/removals from products used by the organization.

- Group 5: Indirect emissions/absorption due to the use of the company's products. / Group 5: Indirect GHG emissions/ removals associated with the use of products from the organization.

- Group 6: Indirect emissions/removals from other sources / Group 6: Indirect GHG emissions/removals from other sources

Calculate and measure greenhouse gas emissions

How to calculate (according to the IPCC Intergovernmental Climate Change Panel)

- Scope 1: Direct GHG emissions

   GHG emissions from fuel combustion for non-moving equipment

Fuel GHG emissions = Fuel consumption * Fuel emission factor

Total GHG Emissions from fuel combustion = S GHG emissions per fuel type

   GHG emissions for road transport equipment

GHG emissions = S Fuel consumption (Fuel) fuel a * Emission factor (EF) fuel a

- Scope 2: Energy - Indirect GHG emissions

Electricity GHG emissions = Electricity consumed * Emission factor (EVN)

- Scope 3: Indirect greenhouse gas emissions

GHG Emissions = GHG Activity Data x Emission Factor

GHG activity data collected is quantitative in terms of the level of greenhouse gas emission and removal activities in a certain period.

Emission factors measure the volume of GHG emissions and removals relative to a unit of activity. Emission factors may vary depending on the overall situation reflecting average values by industry, technology type, and/or fuel type.

How to collect operational data for greenhouse gas inventories

A question that needs to be answered when collecting activity data for greenhouse gas inventories is to do so in such a way that the collected data has the highest reliability and accuracy. In reality - data is not available, but to have it, the organization must establish how it is collected.

How to collect data for some common data types:

1 - For operational data on energy consumption such as electricity, gasoline, oil, gas, and coal... we collect data as follows:

- Identify which energy-consuming households consume which type of energy and how often they use it

- Separate consuming households for separate monitoring (For example: If the workshop has 5 cutting machines and 1 copper furnace - at least it must be separated into 2 energy consuming households - 1 household is the freezing furnace, 1 household is 5 machines. cutting - to monitor separately by electricity meter. In addition - if the factory is divided into production stages - it is best to request separate monitoring of energy consumption of each stage)

- Create a table to collect consumption data (monitor daily consumption, summarize data for monthly and annual reports)

2 - Industrial processes

- Identify the main industrial processes in the factory - compare with the IPCC to see if there are guidelines for calculating greenhouse gas emissions for the corresponding industrial processes at the Company. If available - necessary data will be collected to calculate greenhouse gas emissions by each industrial process

3 - For operational data is wastewater and garbage emission/treatment

- It is necessary to determine how many emission sources there are, from which stages, and from which point meters or scales will be placed before bringing them to the centralized area.

- For waste - must specifically classify types of waste for separate weighing (domestic, industrial, hazardous waste)
