Environmental Knowledge Center

Pre-construction study of a project's environmental impacts. Mandatory for Category A and B facilities.

Mandatory annual filing to NCEC within 90 days of year-end, signed by a licensed consultant.

Royal Commission Environmental Regulations 2025 for Jubail, Yanbu, and Ras Al Khair industrial cities.

Four-tier penalty schedule from SAR 5,000 to SAR 10,000,000 plus criminal referral for gross pollution.

Climate-tech systems that remove CO₂ directly from ambient air — central to Saudi Arabia's Vision 2030 net-zero pathway and Saudi Green Initiative.

End-to-end CO₂ management — capture from point sources or air, transport, utilization, and geological storage. A Vision 2030 priority for KSA.

Inhalable particles ≤2.5 µm and ≤10 µm. NCEC annual limits: 15 µg/m³ (PM2.5) and 50 µg/m³ (PM10).

Acidic gas from fuel combustion. NCEC 1-hour limit: 200 µg/m³; daily limit: 80 µg/m³.

Organic vapours that contribute to ozone and odour. Regulated by sector under RCER-2025.

Real-time stack analyzers transmitting data to NCEC. Mandatory for major combustion sources under RCER-2025.

Empirical models that predict emissions from process parameters. Accepted as CEMS alternative for select sources.

Stack-test technique where sample velocity equals stack velocity to ensure representative particulate capture.
