Independent Field Asset Emission Measurement · Oman & GCC

Emissions intelligence.
Asset by asset.

EmitScan delivers independent, field-measured exhaust emissions profiling for industrial combustion assets across Oman and the GCC. ISO 8178-aligned. QA/QC procedures informed by ASTM D6522, where applicable. Inspection-ready records — not estimates.

What we do

We measure your assets' exhaust emissions — accurately, one by one.

EmitScan sends an experienced field engineer to connect calibrated instruments directly to each asset's exhaust — capturing real concentrations under actual load, fuel, and field conditions. Every asset gets its own signed report and a clear pass or flag against international benchmarks. No spreadsheet estimates, no generic factors — actual measurements.

What we measure on every asset

NOx Nitrogen Oxides (NO + NO₂)

CO Carbon Monoxide

SO₂ Sulfur Dioxide

CO₂ Carbon Dioxide

O₂ Oxygen — combustion efficiency

HC Total Hydrocarbons (CxHy)

What you get from it

Asset health & predictive maintenance Elevated CO or rising NOx across visits flags wear before it becomes a breakdown — advance notice, not a surprise.
Fuel burn efficiency tracking Excess air, O₂, and exhaust temperature show whether each engine is burning fuel efficiently — measurable, asset by asset.
Precise Scope 1 emissions — not a generic guess GHG Protocol Tier 3 measured data for every asset — not an IPCC factor multiplied by fuel consumption, but actual measured CO₂e, signed and dated.
ESG-ready records & regulatory defensibility Every measurement is signed, dated, and benchmarked against Oman MD 118/2004 and World Bank EHS Guidelines — so when a regulator asks for evidence, it's already filed.

The measurement advantage

Most Scope 1 inventories are built on estimates. Ours are built on accurate field measurement.

Most industrial operators across the GCC calculate Scope 1 emissions using GHG Protocol Tier 1 or Tier 2 methods — a generic IPCC or API factor multiplied by fuel consumption, with no relationship to your specific equipment, fuel, load, or desert operating conditions. It's a starting point, not evidence.

EmitScan delivers GHG Protocol Tier 3: direct field measurement, asset by asset, visit by visit — a difference that's commercial and regulatory, not just methodological.

Measurement may reveal meaningful differences from factor-based estimates. EmitScan gives you the signed, instrument-validated measurement to demonstrate that — to any auditor, regulator, or project owner.

Our services

Two tiers of measurement depth

Both tiers use the same rigorous field methodology and certified instruments. Tier 2 adds mass flow measurement and g/kWh conversion, enabling EPA Tier limit comparison and Scope 1 GHG inventory output.

TIER 1

Combustion Health & Emissions Concentration Audit

On-site exhaust gas measurement with the Testo 350 MCERTS-certified analyser — full chemistry per asset, benchmarked against World Bank EHS Guidelines and Oman MD 118/2004.

TIER 2

GHG Mass Emissions Inventory & EPA Tier Classification

Everything in Tier 1, plus mass flow measurement converted to g/kWh — the unit required for EPA Tier limits and ISO 8178-4 — delivering a Scope 1-ready inventory aligned to GHG Protocol Tier 3 and GRI 305.

Regulatory environment

GCC environmental regulations are tightening. A measured baseline now is a strategic asset.

Under Royal Decree 114/2001, Ministerial Decision 118/2004, and tightening operator HSEMS requirements, organisations without a documented, measured emissions baseline are increasingly exposed to inspection risk and ESG audit gaps. A field-measured baseline now is the evidence your regulators, auditors, and financiers are starting to require.

Asset Health Passport

Every asset.
A permanent record.

After each measurement visit, every asset receives an updated passport — a dated, signed emissions profile that accumulates with every visit. Over time, this becomes your most defensible emissions document.

Trend analysisRising CO over three visits signals an injector issue before it becomes an unplanned shutdown or a failed inspection.
Inspection readinessWhen a regulator or project owner requests emissions records, the answer is organised, signed, and dated.
Scope 1 data exportReadings exported directly into your GHG Protocol Scope 1 inventory and GRI 305 ESG disclosure workflow.
