Environment: ACA certificate renewals in the VINCI Airports network

Lyon-Saint Exupéry airport has renewed its ACA3+ certificate (the highest level on the greenhouse-gas emission-reduction programme). The airport has remained at the top of the scale since it earned ACA3+ accreditation in May 2017. ACI delivers this certificate when an airport achieves carbon-neutral status.

All the airports in Portugal have also renewed their ACA2 certificates in June 2018 and the Phnom Penh, Siem Reap and Sihanoukville airports in Cambodia renewed their level 1 accreditation in March 2018.

These renewals are part of VINCI Airports’ commitment to secure and retain ACA certificates for all the airports in its network. VINCI Airports’ comprehensive environmental strategy, AirPact, sets common objectives looking at 2020.


The Airport Carbon Accreditation is an initiative of the ACI (Airports Council International) and is a specific programme for the management of carbon emissions for airports. Through it, the ACI evaluates and recognizes the Airports’ efforts to manage and reduce their carbon emissions, with four levels of recognition: “Mapping”, “Reduction”, “Optimization” and “Neutrality”. This programme, which began with ACI Europe, was later extended to the global level.
