Air Emission Inventory

Service Overview

A complete, defensible air emission inventory is the foundation of environmental permitting, regulatory reporting and internal emissions management. Green Vertex builds facility-wide inventories that capture point source, fugitive and area source emissions, structured to meet the reporting requirements of Saudi and international regulators.

Emission inventories are only as good as the data and assumptions behind them, and gaps are often only discovered during a regulatory audit. Our engineers combine site walk-downs, process data review and recognized emission factor methodologies to build an inventory that holds up to scrutiny and stays current as your operations change.

Our Offering

What We Offer for Air Emission Inventory

Point Source Emission Inventory

Quantification of emissions from stacks, vents and other identifiable point sources across the facility. Calculations use direct measurement data where available, supplemented by recognized emission factors.

Fugitive Emission Estimation

Estimation of fugitive emissions from valves, flanges, storage tanks and material handling operations. Combines component counts with correlation equations or LDAR survey data.

Emission Factor Development

Selection and, where needed, development of facility-specific emission factors. Improves inventory accuracy beyond generic default factors.

Regulatory Reporting Support

Preparation of emission inventory submissions in the format required by relevant environmental authorities. Reduces the administrative burden of annual reporting cycles.

Inventory Verification & QA/QC

Independent review and quality assurance of existing emission inventories. Identifies calculation errors, missing sources and outdated factors.

Emission Reduction Planning Support

Analysis of inventory data to identify the largest contributing sources and cost-effective reduction opportunities. Supports both compliance planning and voluntary reduction initiatives.

FAQ

Frequently Asked Questions

An Air Emission Inventory is delivered by Green Vertex's specialist team using internationally recognized methodologies. It quantifies point, fugitive and area source air emissions across your facility. The scope is tailored to your facility, project type and applicable regulatory requirements in Saudi Arabia and the wider GCC.

Timelines depend on facility size, number of emission sources and data availability. A straightforward inventory can be completed within a few weeks of mobilization, while larger or multi-site facilities may take longer. We confirm a firm schedule during project scoping.

Many industrial facilities in the Kingdom are required to maintain and periodically update an air emission inventory as part of their environmental permit conditions. Our team can confirm the specific obligations that apply to your operation.

Green Vertex combines ISO-certified quality management, experienced specialists and recognized inventory methodologies to deliver an air emission inventory that is accurate, defensible and delivered on schedule — backed by responsive client support throughout the project.
