​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.

Managing Environmental Sustainability

No longer can environmental adaptation and impacts be seen and managed as external risks. To be effective, environmental sustainability management must be part of day to day operations and decision-making.

IEnvA provides airlines, aircraft maintenance services, on-board catering services and ground handlers definitive guidance, aligned with internationally accepted management standards to effectively address the most significant environmental sustainability matters that face the aviation industry today.

Driving True Sustainability Through Management and Operational Performance

  • Organization-wide alignment and direction of ESG Policy, communications, projects and programs
  • Scalable and phased implementation options for airlines of all sizes, resource-accessibility, locations and internal business requirements
  • Independent, external assessments carried out by a smart combination of highly experienced IOSA Lead Auditors and ISO14001 auditors
  • ISO14001:2015 verification certificate
  • Reduced risk and fines related to regulatory compliance using a user-run database approach
  • Improved financial performance resulting from industry best practice operational controls reducing resource-use
  • Continuously evolving best recommended practices and guidance on the most significant sustainability risks the industry faces today
  • An aviation-friendly management system and program, using a familiar program and assessment structure, governance and documentation, based on IATA’s industry leading IOSA and ISAGO programs

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. 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.
