International buyers increasingly expect their suppliers to provide reliable information about greenhouse gas emissions. For Bangladeshi export industries, especially garment and textile factories, carbon reporting is becoming an important part of supplier assessments, sustainability programs, and long-term business planning.
However, many factory owners are unsure where their emissions come from or how to calculate them. The solution starts with understanding Scope 1, 2, and 3 emissions, the three categories used by the Greenhouse Gas (GHG) Protocol to organize a company’s carbon footprint.
What Are Scope 1, 2, and 3 Emissions?
A carbon footprint measures the greenhouse gases associated with a company’s activities. These emissions are commonly reported in metric tons of carbon dioxide equivalent (tCO₂e).
The three scopes help factories organize their emissions and understand where reductions are possible.
1. Scope 1 Emissions: Direct Fuel and Other Direct Emissions
Scope 1 includes direct emissions from sources owned or controlled by your factory.
Common examples include:
- Natural gas burned in boilers and thermic fluid heaters.
- Diesel consumed by captive generators and company vehicles.
- Fuel used in factory-owned equipment.
- Refrigerant leaks from air conditioning and cooling systems.
Factory managers can reduce Scope 1 emissions by improving boiler efficiency, maintaining equipment, preventing refrigerant leaks, and reducing unnecessary fuel consumption.
2. Scope 2 Emissions: Purchased Electricity
Scope 2 covers emissions associated with generating the electricity, steam, heating, or cooling purchased and consumed by your facility.
For many Bangladeshi factories, purchased electricity from the national grid is a major source of Scope 2 emissions.
Factories can reduce these emissions through energy-efficient motors, optimized compressed air systems, efficient cooling equipment, and suitable rooftop solar projects.
Accurate reporting requires reliable electricity consumption records and the appropriate emission factor for the reporting method and period.
3. Scope 3 Emissions: Your Entire Value Chain
Scope 3 includes other indirect emissions from activities across your company’s value chain.
For a garment factory, these may include:
- Purchased cotton, polyester fabric, yarn, and sewing thread.
- Dyes, chemicals, buttons, zippers, and packaging materials.
- Transportation of purchased materials and finished products.
- Waste generated by factory operations.
- Other relevant upstream and downstream activities.
Scope 3 can represent a large share of a fashion brand’s overall footprint. However, its size varies by company and depends on which activities are included in the assessment.
Although suppliers may have less direct control over these emissions, they can work with material suppliers, logistics companies, and buyers to identify reduction opportunities.
Why Do Carbon Emissions Matter for Bangladesh’s Export Industry?
International brands increasingly use supplier data to understand the environmental impact of their supply chains. Programs such as the Higg Facility Environmental Module (Higg FEM) also assess facility-level environmental performance, including relevant energy and greenhouse gas information.
European sustainability rules can create additional supply-chain data needs. For example, the EU Corporate Sustainability Due Diligence Directive applies to companies within its legal scope and may influence the information they request from business partners. Meanwhile, the EU Carbon Border Adjustment Mechanism (CBAM) currently covers selected sectors, including cement, iron and steel, aluminum, fertilizers, electricity, and hydrogen—not finished garments as a general product category.
For Bangladeshi exporters, the practical message is clear: reliable emissions information can help support buyer reporting, supplier assessments, and carbon reduction planning.
How Can Your Factory Calculate Its Carbon Footprint?
Start by collecting electricity bills, gas consumption records, diesel purchase data, refrigerant records, material purchase quantities, and transportation information.
Next, calculate emissions by multiplying relevant activity data by an appropriate emission factor.
For example, electricity consumption is multiplied by a suitable electricity emission factor to estimate the associated emissions. The same principle applies to fuel and purchased materials.
Finally, document the reporting period, organizational boundary, calculation methods, data sources, and assumptions. Use the GHG Protocol and relevant ISO 14064-1 guidance to structure the inventory and reporting process.
Third-party verification may be appropriate when required by a buyer, financing arrangement, or reporting framework. A credible inventory should never rely on unsupported estimates when better data is available.
