More About the Program

IATA’s Environmental Assessment (IEnvA) Program is an environmental management system (EMS) that has been designed for the airline and broader aviation industry to achieve ISO14001:2015 compliance.

The Environmental Assessment Program was developed by industry experts, ISO management system experts and airline operators, and continues to evolve and improve to enable IEnvA Airlines to be at the top of the Environmental Management game. IEnvA Standards are externally assessed and verified to comply with ISO14001:2015 requirements.

IEnvA provides airlines with an industry-specific approach to establish international standardized environmental management processes efficiently and effectively, making use of airline-developed recommended practices and solutions to the most common environmental challenges faced by airlines today.


All IEnvA Operators conform to a minimum IEnvA Scope. This Scope defines where IEnvA Standards are applicable, driving environmental management principles, performance, and compliance. IEnvA Operators have a choice to include these areas in the Scope of their IEnvA Systems.
