SUSTAINABILITY REPORT 4

SOCIAL AND SOCIETAL MATTERS

4.3.3.1 Reducing noise pollution Reducing noise pollution is part of Groupe ADP's commitment to reducing noise pollution to improve the quality of life of local residents. Where the data points do not include information concerning TAV Airports and AIG, this means that the information in this first reporting period could not be collected. S3-1 – Noise reduction policy The noise reduction policy implemented as part of the Vigilance Plan has two main strands: u reducing noise pollution at the source; u reducing the sound impact of aviation activity on local residents in their homes. Pursuant to articles 26 and 37 of the decree of 20 July 2005 1 , ADP SA has been entrusted by the French State with the measurement of noise generated by aviation activity at its airfields. This includes: u aircraft noise monitoring: noise levels around the major Paris airports are measured continuously by a network of noise measurement stations equipped with a microphone and a noise analyser; u noise mapping, which feeds into risk mapping, with the aim of: u limiting urbanisation around the airport with the Noise Exposure Plan (NEP), u delineating the residents living in municipalities near airports who are entitled to assistance for soundproofing their homes, as well as the educational establishments and health or social facilities concerned by this aid (Noise Reduction Plan); u assessment of changes in noise impact, year after year (ESM: Environmental Sound Maps); u noise pollution is monitored at all the Group's consolidated hubs and is the subject of policies and action plans where necessary. [S3-1-14] → Policies to manage material impacts, risks and opportunities related to affected communities, including specific affected communities or all affected communities The policy of assisting in the soundproofing of homes near airports was introduced in France by the law of 31 December 1992 against noise pollution. The aim of this law is to protect people living in areas exposed to excessive levels of noise. It is designed to finance (all or part of) soundproofing work on homes, depending on their level of exposure to airborne noise (zone 1, 2 or 3). The programme of works is drawn up on the basis of the specific features of the dwellings (collective/individual housing) and the noise reduction targets specified in order to reduce the level of exposure to noise. The work can involve replacing openings (windows/ doors), ventilation (mechanical or grilles), and wall and roof insulation. The scope of this aid covers the areas defined by the noise reduction plans (NRP) for each airport. The airport managers concerned (by NRPs) are responsible for implementing this policy defined by the French state under the supervision of the Directorate General of Civil Aviation.

Groupe ADP applies this policy through the soundproofing assistance scheme described in S3-4 – Action plans put in place to prevent, mitigate and remediate the impact of noise pollution. [S3-1-15] → Disclosure of any particular policy provisions for preventing and addressing impacts on indigenous peoples Not applicable: no indigenous peoples on our rights of way. [S3-1-16] → Description of relevant Human Rights policy commitments for affected communities See section 4.3.b. on the general approach to Human Rights duty of vigilance. [S3-1-16-(a)] → Communication of the general approach to respect for the Human Rights of communities, particularly indigenous peoples See section 4.3.b. on the general approach to Human Rights duty of vigilance. [S3-1-16-(b)] → Disclosure of general approach to engagement with affected communities See section 4.3.b. on the general approach to Human Rights duty of vigilance. [S3-1-16-(c)] → Disclosure of general approach to measures to provide and/or enable remedies for Human Rights impacts The Group whistleblowing system is an essential part of the Vigilance Plan's detection measures. It makes it possible to report any breach of the provisions of the Code of Conduct, in particular a serious violation of the environment, Human Rights, fundamental freedoms or the health and safety of individuals (within the scope of the Potier law on the duty of vigilance) – see section 4.4.2.4 of this report, paragraph [G1-1-10-(a)] → Description of the mechanisms for identifying, reporting and investigating concerns about unlawful behaviour or behaviour in contradiction of its code of conduct or similar internal rules. [S3-1-17] → [S3] Description of whether and how policies are aligned with relevant internationally recognised standards International law Public policy on noise management is laid down at international level by the International Civil Aviation Organization in its resolution A33/7, which describes a "balanced" approach to noise management based on a series of action levers. This method is applied in Europe (EU Regulation no. 598/2014) and in France. The four pillars of this approach are: u reducing aircraft noise at the source; u planning and managing land use; u operating procedures; and u as a last resort, operating restrictions.
