RELEVANCE AND CHOICE OF INDICATORS, CHANGE IN SCOPE

Given its business model, Aéroports de Paris does not take part in any particular initiatives in the fight against food insecurity, respect for animal welfare and responsible, or fair and sustainable food. 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 the scope of activity from one year to another; ◆ the difficulty of retrieving information in the event of subcontracting to, and/or joint ventures with, external partners; ◆ procedures for collecting and entering such information; ◆ availability of data during the reporting year. The 2021 Universal Registration Document lists data known by the Group at the date of document filing. 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. For waste indicators: ◆ non-hazardous waste includes all the waste generated at the airports by the activities of ADP and its stakeholders and which is managed under the responsibility of ADP via ◆ the regulatory obligations set by the French government; ◆ the Group’s performance and impact in relation to the 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 indicators published by Aéroports de Paris are intended to report, with complete transparency, the Group’s annual results with respect to social responsibility, and if applicable, stakeholder expectations. 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 corporate social responsibility policy and commitments;

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: ◆ the environmental and energy policy; ◆ the fight against climate change; ◆ air quality; ◆ waste management and the circular economy;

◆ water and soil management; ◆ the 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 drafting of the Universal Registration Document (URD).
