4 SUSTAINABILITY REPORT ENVIRONMENTAL MATTERS

u Measurable : The volume of emissions reduced or removed by the offset project can be quantified with a minimum of error. u Verifiable : The reduction, avoidance or sequestration of emissions must be verifiable and accounted for by an independent and competent third party in accordance with the verification requirements specified in the offsetting standard. u Permanent : The offset project must take the necessary measures to avoid the recurrence of GHG emissions that could be unintentionally generated by the offset project activities or technologies. For offset projects with a high risk of recurrence of GHG emissions, such as agriculture, forestry and other land use, risk assessments and ‘safeguard measures’ must be put in place to avoid this risk. u Unique : The offset project must not be registered under several offset standards and the GHG emission reductions/ removals must not be issued or claimed by several actors. Moreover, offset projects must not have negative externalities for local populations ( i.e. , Human Rights, etc.) or the environment ( i.e. , biodiversity, etc.). Offset projects must have co-benefits in line with the UN's list of Sustainable Development Goals. E1-8 – Internal carbon pricing The use of an internal carbon pricing system in the process of validating investment projects, from the upstream phase (feasibility studies and design), tends to encourage sobriety in terms of CO 2 emissions during the construction and operating phases. [E1-8-63-(a)] → Type of internal carbon pricing scheme Groupe ADP uses two complementary internal carbon pricing schemes: 1. The Carbon shadow price: a carbon price defined by the company is incorporated into investment decisions and applied to the greenhouse gas emissions generated by projects in the operational phase, so as to have a favourable impact on the economic indicators of projects with low CO 2 emissions. 2. Carbon budget for projects: Groupe ADP has also set itself the objective of defining a carbon budget (maximum volume of GHG emissions authorised in a complete cycle) for all investment projects with a CapEx of more than €5 million. [E1-8-63-(b)] → Description of the specific scope of application of the carbon pricing scheme 1. Scope of the benchmark internal carbon price: The benchmark carbon price is mandatory for projects (whose emissions are recorded in Scope 3 Category 2) that have a direct impact, upwards or downwards, on energy consumption and therefore CO 2 emissions (Scope 1 and 2) and whose CapEx is greater than €3 million. The benchmark carbon price is only applied to hubs in the Paris region. 2. Scope of the project carbon budget: u The introduction of a life cycle carbon budget for all investment projects of more than €5 million will come into force from 2025 for projects at hubs in the Paris region and for TAV Airports (in accordance with KPI 3 of the 2025 Pioneers strategic roadmap). The mechanism will then be applied to AIG.

SPECIFIC FEATURES OF NEUTRALITY OBJECTIVES [E1-7-61] → Public declarations of GHG neutrality involving the use of carbon credits have been made Each Groupe ADP airport that achieves Airport Carbon Accreditation levels 3+ or 4+ offsets its residual greenhouse gas emissions by purchasing certified carbon credits. This offsetting allows these airports to maintain their ACA+ certification, which is public proof of their commitment. Through its independent certification process, the ACA assesses and verifies the carbon management efforts of airports, including their commitment to offset their residual emissions annually via its administrator. By reaching or maintaining these levels, each airport makes a public commitment to offset its emissions in accordance with the programme's requirements. To reinforce this commitment, airports declare their progress in offsetting in their annual sustainability reports and communicate their compliance with ACA requirements through third-party audits every two or three years. This ensures total transparency in the use of carbon credits to achieve the defined climate objectives. [E1-7-61-(a)] → Public claims of GHG neutrality that involve the use of carbon credits are accompanied by GHG emission reduction targets For ACA+ levels, airports commit to offsetting their residual emissions while continuing efforts to directly reduce their internal emissions (Scopes 1 and 2). These efforts are aligned with the requirements of ACA certification, which imposes absolute reduction targets compatible with the IPCC's 1.5°C net-zero or 2.0°C trajectories. [E1-7-61-(b)] → Claims of GHG neutrality and use of carbon credits do not impede or reduce the achievement of GHG emission reduction targets or the net-zero target The claims of GHG neutrality made by Groupe ADP airports and their use of carbon credits neither hinder nor compromise the achievement of GHG emission reduction targets. Groupe ADP considers carbon credits to be a complementary tool, used solely to offset residual emissions after all possible direct reduction efforts have been implemented. [E1-7-61-(c)] → Explanation of the credibility and integrity of the carbon credits used Airports involved in the ACA apply the programme's guidelines (Offset Guidance Document – December 2023: https://www.airportcarbonaccreditation.org/wp-content/ uploads/2023/12/ACA-Offset-Guidance-Document FINAL-09112023-1.pdf). This standard stipulates the minimum requirements to be applied when purchasing carbon credits. Offsets must be certified by one of the following organisations: Gold Standard, VCS, Label Bas Carbone, Climate Action Reserve, American Carbon Registry. This label aims to verify the following requirements (non-exhaustive list): u Real : It must be proven that the GHG emission reductions claimed have been generated by the offset project. u Additional : The emissions that are avoided, reduced or captured are additional. In other words, without the project, without the certification and the financing of the sale of carbon credits, the "reference" scenario would have resulted in emissions or no carbon capturing.
