Greenhouse Gas Inventory Services for the Chemical Sector

Inventory Services for the Chemical Sector help chemical companies identify, quantify, document, and manage greenhouse gas emissions from complex industrial operations. Chemical manufacturing can involve fuel combustion, process reactions, purchased electricity, steam, refrigeration systems, raw materials, transportation, waste treatment, and other activities that may contribute to greenhouse gas emissions.

Because chemical plants can have multiple production lines and different emission sources, greenhouse gas management requires more than a simple calculation. Companies need reliable activity data, appropriate emission factors, clear organizational boundaries, consistent methodologies, and transparent reporting.

Inventory Services for the Chemical Sector can support this process by calculating Scope 1, Scope 2, and relevant Scope 3 emissions, establishing an emissions baseline, identifying carbon hotspots, and developing recommendations for future greenhouse gas reductions.

A structured GHG Inventory can therefore become the foundation for long-term climate management, energy efficiency, decarbonization planning, customer reporting, and internal sustainability decision-making.

What Are Inventory Services for the Chemical Sector?

Inventory Services for the Chemical Sector are professional services designed to quantify greenhouse gas emissions generated by chemical companies across their operations and relevant value chains.

Depending on the company’s activities, the inventory may include emissions associated with:

• Chemical production processes.
• Purchased electricity.
• Purchased steam or heat.
• Cooling and refrigeration systems.
• Fugitive emissions.
• Wastewater treatment.
• Solid waste.
• Raw materials.
• Transportation and distribution.

The objective is to convert these activities into measurable greenhouse gas emissions, usually expressed as carbon dioxide equivalent or CO₂e.

Why Inventory Services for the Chemical Sector Are Important

The chemical industry plays an important role in manufacturing supply chains because chemical products are used in agriculture, pharmaceuticals, construction, consumer goods, automotive manufacturing, electronics, textiles, and many other sectors.

At the same time, some chemical-production processes can be energy-intensive or generate direct greenhouse gas emissions.

Potential greenhouse gases can include:

• Carbon dioxide or CO₂.
• Methane or CH₄.
• Nitrous oxide or N₂O.
• Hydrofluorocarbons or HFCs where relevant.
• Perfluorocarbons or PFCs where relevant.
• Sulfur hexafluoride or SF₆ where relevant.

The presence and significance of each greenhouse gas depend on the production process, equipment, chemicals used, and facility configuration.

Major GHG Sources in the Chemical Sector

One of the first stages of Inventory Services for the Chemical Sector is mapping all potential greenhouse gas emission sources.

1. Fossil Fuel Combustion

Planned venting can also release gases depending on the process.

If the released material contains methane or other greenhouse gases, these emissions may need to be included in the inventory.

6. Refrigerant Leakage

Cooling and refrigeration equipment may contain refrigerants with significant global warming potential.

Leaks during:

• Operation.
• Maintenance.
• Recharging.
• Equipment disposal.

can create direct greenhouse gas emissions.

7. Waste and Wastewater Treatment

Waste-management systems can also contribute to greenhouse gas emissions.

Wastewater containing biodegradable organic material may generate methane under certain anaerobic conditions.

Some biological treatment systems may also generate N₂O depending on nitrogen content and treatment conditions.
