The Role of AUS40 in Reducing NOx Emissions

Shipping is the backbone of global trade, carrying more than 90% of goods worldwide. But with this essential role comes a heavy environmental footprint. Nitrogen oxides (NOx), produced by marine engines, contribute significantly to air pollution, causing smog, acid rain, and severe health impacts in coastal communities.

AUS40: Cutting NOx, Powering Cleaner Shipping

To address this, the International Maritime Organization (IMO) introduced Tier III regulations, which set strict NOx emission limits for new ships operating in Emission Control Areas (ECAs). For shipowners and operators, compliance is not just about avoiding penalties, it’s about protecting the environment and public health while staying competitive.

How AUS40 Helps

AUS40 (Aqueous Urea Solution, 40%) is a high-quality reagent used in Selective Catalytic Reduction (SCR) systems. When injected into exhaust gases, AUS40 reduces NOx emissions by up to 90%, transforming them into harmless nitrogen and water vapor. This makes it one of the most effective solutions available for meeting Tier III standards.

Key Benefits of AUS40:

• Environmental Impact: Significant reduction in harmful NOx emissions.

• Regulatory Compliance: Enables vessels to operate within Tier III ECAs.

• Operational Efficiency: Avoids costly penalties and supports sustainable business strategies.

• Proven Technology: Widely adopted in the global shipping industry.

As global shipping faces increasing regulatory pressure and stakeholder demands for cleaner operations, AUS40 provides a practical and scalable pathway to compliance. Its role extends beyond regulations, it supports a more sustainable maritime future.
