Environmental Management Systems (EMS) certified according to the ISO 14001:2004 standard have been implemented in the Engineering and Flight Operations Divisions, as well as in SIA Engineering Company. Objectives and measurable targets are set for the environmental action programmes under the EMS. These are reviewed and updated periodically to ensure legal compliance and consistency with our commitment to reducing pollution. Operations that have an environmental impact are regularly monitored. Measurements are also taken to ensure that the applicable controls are documented and implemented in compliance with the EMS.
