What is Stationary Combustion? Examples & How to Reduce It

Understanding the Types of Scope 1 Emissions

According to the GHG Protocol, Scope 1 emissions are defined as direct emissions from assets controlled by the company. These cover four important categories:

For a deeper understanding of each category, please refer to the following:

• Stationary Combustion: Emissions from the combustion of fuels by stationary machines (boilers, generators).
• Mobile Combustion: Emissions from the combustion of fuel by motor vehicles.
• Fugitive Emissions: Emissions from gas leaks (methane, refrigerants).
• Process Emissions: Emissions from chemical reactions in industrial processes.

Definition of Stationary Combustion

In the context of greenhouse gas emission calculations, emissions from fuel combustion in stationary equipment (non-mobile) are part of Scope 1, known as stationary combustion. These emissions are produced from the direct combustion of fossil fuels at fixed sources owned or controlled by the company.

Examples include:

• Diesel-fueled generator sets
• Steam boilers for industrial processes
• Furnaces and room heating systems

Stationary combustion is important because many companies rely on these energy sources for their daily operations, especially in the manufacturing, energy, and office sectors.

Examples of Emission Sources

Emission sources from stationary combustion are typically centralized and operate consistently at the same location. Here are some main examples:

• Generator sets (gensets) for backup electricity supply
• Boilers for steam production in factories
• Furnaces in processing industries
• Water and room heaters using gas or solar fuel

These sources usually consume fuels such as diesel, LNG, LPG, or biomass, depending on needs and operational location.

Use the Carbon Emission Accounting Platform from Jejakin

To avoid manual calculation errors, companies can use CarbonIQ, Jejakin's platform to manage and calculate carbon emissions automatically. Just enter:

• Type of equipment (e.g., genset, boiler)
• Type of fuel
• Usage volume per period

CarbonIQ will calculate total emissions, compare performance between locations/units, and provide recommendations for emission reduction.

Why Should It Be Calculated and Reported?

Emission sources from stationary combustion like gensets, boilers, and industrial furnaces are often considered routine parts of daily operations. However, due to their consistent and repetitive nature, emissions from stationary combustion can actually be the best starting point for energy efficiency and decarbonization—if calculated and reported accurately.

Here are the reasons why emissions from stationary combustion must be reported:

• Energy audit and system efficiency: Reporting provides historical data on energy consumption from stationary equipment, making it possible to optimize or replace them with more efficient models.
• Fuel source-based regulations: Many national regulations differentiate emissions from stationary combustion and impose separate carbon taxes or incentives.
• Benchmarking between locations or plants: Emission data from gensets and boilers allows companies to compare performance across production facilities.
• ESG and ISO 14064 reporting requirements: Emission reporting from combustion systems is mandatory in sustainability reports and environmental management systems (EMS).

How to Reduce It

After identifying the total emissions from stationary combustion, here are some ways to reduce them:

• Upgrade to high-efficiency equipment, such as inverter gensets.
• Use renewable energy such as solar panels or hybrid systems.
• Optimize operational schedules, avoiding use beyond what is necessary.
• Conduct regular energy audits to detect fuel wastage.
• Monitor performance in real time using platforms like CarbonIQ.

Conclusion

Emissions from stationary combustion are often overlooked, even though their impact on a company’s total carbon footprint is significant. By accurately calculating and reporting them, companies not only meet global reporting standards but also discover major opportunities for energy efficiency.

Use technology like CarbonIQ to simplify inventory, reporting, and emissions management processes comprehensively and sustainably.
