What we do

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

EmitScan sends a certified field engineer to your site and connects calibrated measurement instruments directly to each combustion asset's exhaust. We capture the real concentrations of every exhaust gas your engines produce — under actual operating load, actual fuel, and actual field conditions.

Every asset gets its own signed report, a permanent emissions record, and a clear pass or flag against international benchmarks. No spreadsheet estimates. No generic emission 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 means incomplete combustion — a warning your injectors need attention before a breakdown. Rising NOx over successive visits signals engine wear before it becomes a costly failure. Our data gives your maintenance team advance notice, not a surprise.
  • Fuel burn efficiency tracking Excess air ratio, O₂ concentration, and exhaust temperature tell you whether each engine is burning fuel efficiently or wasting it. Optimising combustion directly reduces fuel costs — measurable, asset by asset.
  • Precise Scope 1 emissions — not a generic guess We give you GHG Protocol Tier 3 measured data for every asset — the highest evidential level for Scope 1 reporting. Not an IPCC emission factor multiplied by fuel consumption. Actual measured CO₂e, per asset, signed and dated.
  • ESG-ready records & regulatory defensibility Every measurement is signed, dated, instrument-certified, and benchmarked against Oman MD 18/2009, World Bank EHS Guidelines, and EPA Tier limits. When a regulator or project owner asks for emissions evidence, your answer is already filed.

The measurement advantage

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

The majority of industrial operators across the GCC currently calculate Scope 1 emissions using GHG Protocol Tier 1 or Tier 2 methods — multiplying fuel consumption by a generic IPCC or API emission factor derived from laboratory conditions and average global engine populations.

These factors carry no relationship to your specific equipment model, age, fuel sulfur content, operating load, or the reality of running at 45°C in desert conditions. They are a starting point — not evidence.

EmitScan delivers GHG Protocol Tier 3: direct field measurement, asset by asset, visit by visit. The difference is not just methodological — it is commercial and regulatory.

In the majority of cases, actual field-measured emissions are lower than generic emission factor estimates. EmitScan gives you the signed, instrument-validated measurement to demonstrate that — to any auditor, regulator, or project owner.

Who we serve

We measure every engine's combustion profile that drives the GCC economy

Each sector carries a different combustion profile and regulatory obligation. EmitScan measurement programmes are configured to the specific equipment type and applicable test cycle for your fleet.

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 full EPA Tier classification and Scope 1 GHG inventory output.

Methodology

Three-standard measurement framework

Every EmitScan measurement is grounded in a coherent stack of international standards — covering field procedure, instrument performance, and regulatory benchmarking.

Regulatory environment

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

Industrial emissions regulation across Oman and the GCC is at an inflection point. Royal Decree 114/2001, Ministerial Decision 18/2009, and evolving operator HSEMS requirements mean that organisations without a documented, measured emissions baseline are increasingly exposed — to inspection risk, to ESG audit gaps, and to regulatory catch-up costs.

Establishing a field-measured baseline before regulatory scrutiny arrives positions your organisation ahead of the curve. It also provides the verified data your project owners, ESG auditors, and financing institutions are beginning 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.
  • Client portal accessAll asset records across all sites, in a secure online dashboard updated after every measurement visit.
