The IATA Environmental Assessment (IEnvA) program is an evaluation system designed to independently assess and improve the environmental management of an airline.

IEnvA is a voluntary program based on principles in compliance with environmental obligations and a commitment to continually improve environmental management.

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.

Key documents



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.

Benefits for airlines

  • Quality environmental assessment program under the stewardship of IATA based on the successful IATA Operational Safety Audit (IOSA) and IATA Safety Audit for Ground Operations (ISAGO) programs
  • Dynamic program with continuous updating of standards to reflect regulatory revision and environmental best practices overseen by an advisory group of 14 airlines
  • Independent assessments by accredited Environmental Assessment Organizations (EAOs), maximizing the use of online tools and data exchange
  • Reduced regulatory compliance risk, improved financial benefits from resource saving and demonstration of good environmental governance
  • Two-stage implementation approach based on core airline activities of flight operations and corporate activities allows for early recognition of environmental management achievements

IEnvA recognizes that airlines have varying environmental management capacities and experience, and the adoption of a staged implementation approach allows for wider airline participation. Airlines are able to phase the implementation of the IEnvA program with recognition as Stage 1 or Stage 2 Operator.

IEnvA Stage 1

Stage 1 allows the airline to set the framework for its EMS and identify and comply with its legal requirements and other obligations. IENvA Stage 1 certification is mandatory for IEnvA Stage 2 participation. See the “Signing up and what to expect” PDF in the Resources tab to get your airline on the way to IEnvA certification.

IEnvA Stage 2

Stage 2 is a fully-fledged Environmental Management System in line with international environmental management standards. IEnvA Stage 2 provides an airline with all the tools required to be on top of their environmental management game.
