Selecting Organizational Boundary Setting Methods (Boundary Setting)
Organizational boundary setting is the critical first step in calculating a carbon footprint. It identifies which activities or entities within an organization will be included in the greenhouse gas emissions assessment, ensuring accurate and reliable results in accordance with international standards like the GHG Protocol. There are two main methods for boundary setting: Control Approach and Equity Share Approach.
1. Control Approach
This method accounts for all GHG emissions from entities or activities over which the organization has actual control, whether operational or financial. This approach emphasizes the organization's decision-making power and responsibility.
There are two sub-forms:
Operational Control
  • The organization has full authority to make decisions and set daily operational policies, including environmental policies, and can implement them directly.
  • Example: Company A owns and manages a manufacturing plant solely. Company A has decision-making power over energy use, raw materials, and production processes. Therefore, all emissions from this plant are included in Company A's carbon footprint.
Financial Control
  • The organization has the ability to set and control the financial and operational policies of another entity, and is entitled to financial benefits from that entity.
  • Example: Company B holds a 60% stake in its subsidiary (Company C) and has financial control. Even if Company C operates independently, Company B is responsible for all of Company C's emissions due to its financial control.
2. Equity Share Approach
This method accounts for GHG emissions based on the proportion of ownership (Equity Share) that an organization has in each activity or entity. It focuses on the proportion of economic benefits received.
  • The organization is responsible for GHG emissions in proportion to its equity share or the proportion of economic benefits received from those activities.
  • Example: Company D invests 30% in a coal-fired power plant. Company D will only be responsible for 30% of the emissions from this power plant, according to its investment proportion.






Guidelines for Choosing the Appropriate Method for Your Organization
The selection of the appropriate boundary setting method depends on your organization's structure and business relationships:
  • For most organizations starting out: The Control Approach (especially Operational Control) is often the preferred choice, as it reflects direct responsibility for operations the organization controls and is easier to collect data and manage initially.
  • For organizations with joint ventures or investments in various businesses: The Equity Share Approach may be more suitable, as it clearly reflects environmental impact according to the proportion of ownership or economic benefits received.
Choosing the correct method will ensure that the carbon footprint assessment is credible, transparent, and highly beneficial for setting environmental goals and effectively managing environmental aspects of the organization.
Activity Data Collection Form Templates
Systematic and accurate collection of activity data is the fundamental basis for calculating an organization's carbon footprint. Having standardized forms helps streamline the data collection process, reduce errors, and increase the reliability of assessment results. Here are sample forms you can adapt to collect data for each Scope:
Scope 1 Data Collection Form: Direct Greenhouse Gas Emissions
Covers GHG emissions from sources owned or controlled by the organization, such as fuel combustion in vehicles or machinery, and refrigerant leaks.
Scope 2 Data Collection Form: Indirect Greenhouse Gas Emissions from Electricity Consumption
Involves emissions from the generation of purchased electricity consumed by the organization.
Scope 3 Data Collection Form: Other Indirect Greenhouse Gas Emissions
Covers emissions from activities not directly controlled by the organization but related to its value chain, such as business travel or waste management.
Scope 3: Business Travel
Scope 3: Waste Management
Establishing and consistently using these forms will help you gather all necessary data for accurate and standard-compliant carbon footprint calculations. This is a crucial step towards effective and sustainable GHG emission management for your organization.
Chapter 6: Activity Data Collection
Collecting activity data is the most crucial step in assessing carbon footprint. The accuracy and completeness of the data directly impact the reliability of the results.
Fuel Consumption Data
Record the quantity of all types of fuel used, such as diesel, gasoline, LPG, and natural gas. Specify units in liters, kilograms, or cubic meters, along with the period of use.
Electricity Consumption Data
Collect data from electricity meters or monthly bills, specifying units in kilowatt-hours (kWh). Separate by building or branch if there is more than one location.
Travel and Transport Data
Record travel distances for company vehicles, employee business trips, goods transportation by contractors, and employee commutes (for Scope 3).
Refrigerant Data
Monitor and record the quantity of refrigerants topped up in air conditioning systems and refrigerators, indicating leakage of substances such as R-22, R-410A, R-134a, etc.
Procurement Data
Gather information on the procurement of raw materials, equipment, and services, specifying quantity and value, which will be used for Scope 3 assessment.
Waste Data
Record the quantity of waste and wastewater sent for disposal, separated by type, such as general waste, hazardous waste, recyclable waste. Specify units in kilograms or tons.

\text{GHG Emissions} = \text{Activity Data} \times \text{Emission Factor}
Where:
  • Activity Data = Usage amount (e.g., liters, kWh, km)
  • Emission Factor = Emission Factor (kgCO2e/unit)
  • GHG Emissions = Greenhouse gas emissions (kgCO2e or tCO2e)
Sources of Standard Emission Factors
IPCC Guidelines
The Intergovernmental Panel on Climate Change provides globally applicable emission factors.
TGO Emission Factors

    (from 500,000 liters × 0.0053 kgCO₂e/liter) = 2,650 kgCO₂e (from diesel combustion)
  • HFCs: EF = 1,430 kgCO₂e/kg (assuming 0.5 kg/truck/year leakage, 50 trucks)
    (from 50 trucks × 0.5 kg/truck/year × 1,430 kgCO₂e/kg) = 35,750 kgCO₂e (from R-134a refrigerant leakage in trucks)
Total Scope 1: 1,390,300 kgCO₂e
Scope 2: Electricity Consumption
Electricity consumption in office
  • CO₂: EF = 0.5135 kgCO₂e/kWh (TGO value 2023)

Currently, there is no law mandating all organizations to conduct carbon footprinting. However, listed companies are required to report on sustainability, which includes greenhouse gas emissions data. Organizations that are suppliers to multinational corporations are often required to report, and it is expected that mandatory requirements will increase in the future.
What if data is incomplete?
It is normal for initial data collection to be incomplete. Estimation methods can be used based on available data, or averages from similar organizations can be applied. Assumptions and limitations should be clearly stated in the report. It is crucial to improve the data collection system for the following years.
