Manage IMO CII ratings before they manage your fleet.

The IMO Carbon Intensity Indicator (CII) rates ships annually from A to E based on operational carbon intensity. Poor ratings are no longer theoretical: they trigger corrective action plans, reputational risk, and commercial pressure. VURDHAAN helps operators actively manage CII—year after year.

Tightening every year

CII is an operational performance regime—not a reporting exercise.

Problem

CII is calculated after the year ends—when operational decisions can no longer be changed.

Impact

D or E ratings require corrective action plans and attract scrutiny from charterers, financiers, and regulators.

Solution

Continuous monitoring, forecasting, and operational levers built into voyage and speed decisions.

IMO CII rating bands (simplified)

Rating	Meaning	Regulatory consequence
A	Major superior performance	Positive signal to charterers & stakeholders
B	Minor superior performance	Generally acceptable
C	Moderate performance	Baseline compliance
D	Minor inferior performance	Corrective action plan required
E	Inferior performance	Urgent corrective measures + scrutiny

CII management maturity

Level 2 — Reactive

CII calculated after year-end with limited ability to intervene.

The best time to manage CII is before the rating is fixed.

Let’s move CII from a year-end surprise to a managed operational metric.
