SOCIAL, ENVIRONMENTAL AND SOCIETAL RESPONSIBILITY INFORMATION 17 METHODOLOGICAL NOTE ON SOCIAL, SOCIETAL AND ENVIRONMENTAL REPORTING

Environmental reporting The environmental and social responsibility reporting is limited to the scope of activities of Aéroports de Paris, except in the cases indicated below. Quantitative environmental data for owned subsidiaries are not included in the management report, except for TAV Airport, given the impact and representativeness of the data compared with Aéroports de Paris and the non-material nature of data other than CO 2 emissions. Aéroports de Paris brings together the three airports of Paris-Charles de Gaulle, Paris-Orly and Paris-Le Bourget. For this reporting, TAV Airport brings together its three main platforms: Istanbul Atatürk, Izmir Adnan Menderes and Ankara Esenboğa. The qualitative environmental and social responsibility activities of Aéroports de Paris subsidiaries are included in the relevant sections of the 2018 management report. The scope of scope 3 CO 2 emissions covers external CO 2 emissions of the airports linked to planes, access for passengers and employees, business trips of all employees, ground handling vehicles (GSE), auxiliary power units (APU) for planes, internal waste treatment and consumption in third party buildings as well as subsidiaries emissions of which Aéroports de Paris does not have operational control. Change in consolidation scope Changes in scope of consolidation are taken into account at the time of their actual introduction. ◆ corporate scope: the scope is updated in year N; ◆ environmental scope: the scope is updated in year N+1. However, it is tolerable for acquisitions, disposals, creations of companies or contracts won to be taken into account only after one full year of operation depending on the activity performed. When the data are considered relevant, previous years may be consolidated according to the new scope for ease of comparison ( pro forma ). A change in scope occurred between the 2017 reporting and 2018 reporting: Aéroports de Paris strengthened its position in the capital of Airport International Group (AIG) (51% of the capital) and has fully consolidated AIG’s results since the 2 nd half-year of 2018. For the 2018 financial year, the decision was take not to include AIG in the social (with the exception of the annual average staff numbers published for the scope of the Group including AIG), environmental and societal reporting. Integration is planned for 2019 after a full year of operations Reporting methodology Data collection, calculation and consolidation methods are defined by procedures collected in the social and environmental reporting protocols. These protocols are distributed to the people involved at all levels of reporting development. Relevance and choice of indicators The indicators published by Aéroports de Paris are intended to report, with complete transparency, the Group’s annual results with respect to corporate social responsibility. The indicators are chosen based on the social, societal and environmental impact of group company activity and the risks associated with the company’s strategic challenges.

The data selected are based on a common set of criteria: ◆ Aéroports de Paris’s commitments and corporate social responsibility policy; ◆ regulatory obligations set by the French government; ◆ the Group’s performance and impact in relation to key challenges. The social indicators published by Aéroports de Paris are based on three levels of indicators: ◆ the themes of Article L. 225-102-1 of the French Commercial Code; ◆ the social reporting indicators set forth in French law; ◆ the specific indicators of the Group’s human resources policy. The complementary nature of these three levels of indicators makes it possible to measure the results of the human resources policy and the Group’s commitments in social matters. The environmental indicators are consistent with the themes of article R. 225-102-1 of the French Commercial Code and include: ◆ environmental and energy policy; ◆ fight against climate change; ◆ air quality; ◆ waste management and the circular economy; ◆ water and soil management; ◆ limiting noise and light pollution; ◆ protection of biodiversity; ◆ land development and sustainable construction. The choice of environmental indicators was made using a relevant approach that facilitates understanding of the Group’s real challenges (thanks to the materiality study conducted in 2017) and comparison with companies in the same industry. This choice also takes into account the availability of data at the time of writing of the management report. These challenges are described in detail in the Social Responsibility Report. Methodological limitations and specificities The methodologies used for certain corporate and environmental indicators may have limitations due to: ◆ differences in available professional skills between Aéroports de Paris and its subsidiaries; ◆ specific provisions of social laws in certain countries; ◆ changes in scope of activity from one year to another; ◆ the difficulty of retrieving information in the event of subcontracting to, and/or joint ventures with, foreign partners; ◆ procedures for collecting and entering such information; ◆ availability of data during the reporting year. The 2018 management report lists data known by the Group at the year-end date. However, these data may need to be corrected over the next year if a significant anomaly is found and backed up by detailed supporting evidence. With effect from 2014, the consolidation of data on internal electricity consumption is calculated using the Airport Carbon Accreditation method.
