Navigating IMO 2025: A Practical Guide to New Emission Regulations

The IMO’s 2025 emission targets mark the next big shift in maritime compliance. After the 2020 Sulphur Cap, focus turns to Tier III NOₓ in ECAs and the Carbon Intensity Indicator (CII). Here’s how Carat Maritime helps you meet these requirements without sacrificing vessel performance.

By January 1, 2025, ships operating in designated Emission Control Areas (ECAs) must meet Tier III NOₓ limits—a 75% reduction versus Tier I. Simultaneously, the CII rates each ship A–E based on CO₂ output per cargo capacity; repeat D or E ratings trigger corrective action plans.

Technical pathways include engine tuning, SCR retrofits (up to 90% NOₓ reduction), and exhaust gas cleaning systems (scrubbers). Carat Maritime’s engineers recalibrate fuel-injection timing and turbo settings, then install and commission SCR units to ensure Class approval.

Operational Best Practices

Documentation is equally critical. Our team trains crews on digital logbooks, calibration of engine-monitoring systems, and port-state control audit prep. We perform pre-audit reviews of bunker delivery notes, performance reports, and wash-water analyses.

Carat Maritime offers a turnkey solution—gap analysis, procurement, installation, and certification—so you deal with one partner from start to finish. Early action avoids last-minute drydock rushes and skyrocketing retrofit costs.

Embrace IMO 2025 now to secure an A or B CII rating, demonstrate environmental leadership, and safeguard your operation against penalties and service disruptions.
