Airport Carbon Accreditation (ACA) Verification
Airport Carbon Accreditation (ACA) is the global carbon management certification programme for airports, developed by Airports Council International (ACI) Europe in 2009 and now implemented across all ACI regions worldwide. It is the only internationally recognized voluntary carbon management standard specifically designed for airports.
The ACA programme enables airports to measure, manage, reduce, and ultimately neutralize carbon emissions associated with airport operations through a structured and independently verified framework.
TUV India provides independent ACA Verification services to support airports in demonstrating credible climate action, improving sustainability performance, and achieving international recognition for carbon management excellence.
The objective of ACA Verification is to encourage and enable airports to implement effective carbon management practices and achieve continual greenhouse gas (GHG) emission reductions.
ACA Verification helps airports to:
The ACA programme also promotes knowledge transfer, operational standardization, public recognition, and continuous environmental improvement within the aviation sector.
The ACA programme consists of progressive levels that recognize increasing maturity in airport carbon management practices.
Level 1 – Mapping: Carbon Footprint Measurement
This level focuses on establishing the airport’s carbon footprint by:
Level 2 – Reduction: Carbon Management
In addition to Level 1 requirements, airports must:
Level 3 – Optimisation: Third-Party Engagement
This level expands the carbon management approach by:
Level 3+ – Neutrality: Carbon Neutral Operations
At this stage, airports must:
Level 4 – Transformation
This level focuses on long-term climate transition by:
Level 4+ – Transition
Airports are required to:
Level 5 – Net Zero
The highest ACA level recognizes airports that:
TUV India evaluates the airport’s carbon management system and supporting evidence, including:
ACA Verification is conducted in line with internationally recognized frameworks and programme requirements, including:
