ICAO: International Civil Aviation Organization

I. Definition

ICAO stands for International Civil Aviation Organization.
It is a United Nations agency that sets global rules and standards for international civil aviation.

In simple terms: ICAO coordinates how countries manage air transport so that flights are safe, efficient, and increasingly environmentally responsible.

II. Context

ICAO was created to ensure that international aviation works smoothly across borders.
Airplanes fly between many countries, so common rules are essential.

One of ICAO’s key roles today is climate action.
It developed CORSIA, the global system to limit the growth of aviation CO₂ emissions.

Through ICAO, countries agree on technical standards, reporting rules, and monitoring systems.
Airlines must follow these rules when flying internationally.

Because aviation emissions are global by nature, ICAO acts as the central coordination body.
Its decisions directly affect how emissions are measured, reported, and offset worldwide.

III. Why it matters

At Orizscore, we see ICAO as a key actor in global climate governance.
When rules are global, data consistency becomes essential.

The challenge is not setting objectives.
The challenge is implementation with proof.

Can emissions data be compared across countries?
Can offsetting claims be verified?
Can transparency be ensured at a global scale?

ICAO frameworks, like CORSIA, only work if data is reliable and auditable.
This makes strong ESG data practices a condition for credibility in the aviation sector.

V. Example

An airline operates international flights across multiple continents.
It must follow ICAO rules for safety, operations, and environmental reporting.

Under CORSIA, the airline measures fuel use and CO₂ emissions, reports them, and offsets emission growth when required.
Because ICAO standards are global, the airline uses the same rules regardless of destination.

This creates a common, verifiable framework for managing aviation emissions worldwide.
