1. Introduction
What is a greenhouse gas inventory (GHG)?
A greenhouse gas inventory is the process of collecting, analyzing, and reporting greenhouse gas emissions from an organization, business, or country over a specified period of time. This process helps identify major sources of emissions and assess their impact on the environment.
The Importance of Greenhouse Gas Inventory
GHG inventories play a key role in reducing emissions and protecting the environment. By accurately identifying emissions, organizations can develop effective mitigation strategies, meet legal requirements and international commitments on climate change. At the same time, this helps to enhance reputation and brand image, attracting the attention of environmentally conscious customers and investors.
2. Common greenhouse gases
CO₂ (Carbon Dioxide)
CO₂ is the most common greenhouse gas, mainly produced by burning fossil fuels such as coal, oil and natural gas. CO₂ has the ability to trap heat in the atmosphere, contributing to the greenhouse effect and global climate change.
CH₄ (Methane)
CH₄ comes from agriculture, livestock, waste treatment and oil and gas extraction. Although it stays in the atmosphere for a shorter time than CO₂, CH₄ has a greenhouse effect 25 times greater than CO₂ over a 100-year period, making it a more dangerous greenhouse gas.
N₂O (Nitrous Oxide) and Industrial Greenhouse Gases
N₂O is produced by the use of chemical fertilizers in agriculture and industrial processes. In addition, industrial greenhouse gases such as HFCs, PFCs and SF₆, although less common, have strong greenhouse effect potential and persist in the atmosphere for a long time.
3. Greenhouse gas inventory method
Basic steps
- Data collection: Collect information on emission activities such as energy consumption, raw materials, production processes.
- Data analysis: Process and classify data by emission sources and scope.
- Emissions calculation: Use standard emission factors to calculate GHG emissions.
- Report: Prepare detailed reports on emissions and propose mitigation measures.
Measurement method
- Follow live: Use measuring devices to monitor actual emissions.
- Calculation method: Apply formulas and emission factors to estimate GHG emissions based on activity data.
International standards and supporting tools
Standards such as GHG-Protocol , and ISO 14064 provide guidance and a unified methodology for GHG inventories. These tools help ensure transparency, accuracy, and comparability between emissions reports.

4. Challenges in greenhouse gas inventory
Data Accuracy
Collecting accurate data from multiple sources is a major challenge. Missing or inconsistent data can impact inventory results and mitigation strategies.
Cost and resources
Conducting a GHG inventory requires financial and human resources investment. Many small and medium-sized enterprises have difficulty allocating resources for this activity.
Lack of information and technical support
In less developed areas, access to technology and expertise is limited, making it difficult to apply modern inventory methods.

5. Application of greenhouse gas inventory in practice
Greenhouse gas emissions management and reduction
The inventory results help businesses identify key emission sources and develop effective reduction strategies, such as improving energy efficiency, using renewable energy, and optimizing production processes.
International reporting and commitments
GHG inventories are the basis for businesses to participate in national and international climate reporting programs, meeting the requirements of agreements such as the Paris Agreement.
Sustainable development and green transition
Through GHG inventories, businesses and governments can plan sustainable development strategies, promote the transition to a green economy and minimize environmental impacts.
6. Steps to implement greenhouse gas inventory for organizations
Define scope and objectives
- Analyze the organization's operations to identify emission sources within Scopes 1, 2 and 3.
- Set specific goals for your inventory and emissions reduction process.
Collect and analyze data
- Build an effective data collection system, using supporting software if needed.
- Analyze data to calculate GHG emissions using standard methods.
Reporting and monitoring
- Prepare detailed and transparent GHG inventory reports.
- Establish a continuous monitoring system to track the progress and effectiveness of mitigation measures.
