Sectors

Configured for the assets
the industry actually operates.

Each sector runs different combustion equipment under different duty cycles, fuel types, and regulatory obligations. EmitScan measurement programmes are configured to match the specific combustion profile and applicable ISO 8178 test cycle for your fleet.

Scope 1 — Stationary & Mobile Combustion

Oil & Gas Services

Drilling, well services, and production equipment.

Oilfield operations run a diverse fleet of combustion assets — many operating continuously in remote locations, far from routine HSE oversight. Drilling rigs, production compressors, and well intervention units each carry different exhaust profiles and regulatory obligations.

EmitScan profiles each asset independently, building an asset-level emissions record that supports PDO, OQ, TotalEnergies, and international operator HSE compliance and ESG requirements — and that can be submitted directly to operator HSEMS systems.

Scope 1 — Mobile Combustion Fleet

Construction & Infrastructure

Project site fleets and heavy equipment.

Major GCC construction projects operate large, mixed diesel fleets across project sites — subject to municipal air quality requirements and contractor ESG frameworks increasingly mandated by project owners including NEOM, Muscat Bay, and Oman government infrastructure programmes.

Scope 1 — High-Load Diesel Fleet

Mining & Quarrying

Heavy-duty, high-load engines at scale.

Mining operations run some of the most emissions-intensive diesel fleets in any industry. Large-displacement engines at sustained high load factors produce significant NOx and particulate emissions — and are increasingly subject to environmental permit conditions and sustainability reporting requirements from project financiers.

Maritime & Port Operations

Vessel engines and port equipment.

Vessels operating in GCC waters are subject to MARPOL Annex VI NOx Tier limits and the IMO Data Collection System for fuel consumption and CO₂ reporting. Port authority air quality requirements add a further compliance obligation for port-side equipment.
