Textile The AEI, Ateliers AS and SIEGL sites, which account for 98% of water discharges, are subject to daily self‑monitoring of effluents. To ensure the reliability of these data, audit and calibration plans are regularly implemented. The AEI and Ateliers AS sites, whose effluents are treated by the municipal WWTP, are gradually being equipped with physical and physico‑chemical pre‑treatment plants that will improve the quality of the water discharged. For example, the chemical oxygen demand (COD) will be halved for these entities. Building permits were filed in December 2021 and October 2022. This equipment will be fully operational between late 2023 and early 2024. On the SIEGL site, the new high‑performance WWTP, whose construction began in 2018, is equipped with secondary biological treatments as well as tertiary treatments by membrane filtration and activated carbon. The WWTP is operational and the results are in line with expectations, with COD and BOD5 concentrations below the threshold set by prefectural decree. The site is beginning the second phase of this WWTP relating to wastewater recycling, whose rates will reach 30% in 2023 and 70% in the medium term. Crystal manufacturing The Saint Louis crystal manufacture adopts the same rigorous treatment of its discharges and effluents for the excellence of its production. As such, the processes are continuously improved and optimized upstream to: reduce the quantity of discharges induced by the activity; s reduce the concentration of any pollutants as much as possible in the waste; s guarantee the harmlessness of waste coming out of treatment cycles. s The Cristalleries de Saint Louis have implemented an innovative water purification system based on nature and uses the technique of phyto‑restoration to treat part of the discharged water, a technique more respectful of the environment which avoids the use of physico‑chemical treatment techniques (§ 2.5.3.1.1). Requiring no input of energy or chemicals, the “Jardins de Saint‑Louis” provide optimal water purification and their performance is superior to that of a traditional physico‑chemical installation. This solution is based on a triple device of filtering basins: plant filters, reeds of the phragmites family, planted in peat, can trap suspended matter and nitrogenous pollution; s mineral filters, surrounded by perennial herbaceous plants (miscanthus) then trap the soluble metal compounds by drainage; s finally, plantations of endemic species complete the device and integrate it into the landscape. s Similar to the “Jardins de Saint Louis”, the site developed in 2022 a new solution for treating aqueous effluents from crystal cutting activity. This new system aims to improve the performance of the treatment and recovery of residues present in the aqueous circuit of cutting

2.5.5.2 2.5.5.2.1 No site has been subject to fines, formal notices and/or other sanctions for breaches of regulations on air emissions or water discharges. CHEMICALS MANAGEMENT Compliance of controlled substances General principles Two main activities make it possible to respect Hermès’ commitment as a responsible company marketing products by guaranteeing their regulatory compliance, in all countries where the Group operates: product monitoring and validation: machines, and to limit water consumption by increasing the lifecycle of the water circulating in the network. A study will be undertaken next year with the ambition to duplicate this principle on the workstations of manual grinding wheels or diamond stations. Regular campaigns to measure aqueous discharges and atmospheric tests confirm the performance of the installations in place, for which the site is regularly inspected by the public authorities, with no expression or reservation of comments. Leather Leather goods workshops present limited sources of wastewater discharge thanks to primarily manual production processes that do not require water. The only wastewater discharge concerns water used for washrooms, which does not require on‑site treatment and in most cases is directed to public wastewater collection networks. Only the Maroquinerie de Nontron has a wastewater treatment facility (using the principle of phytoremediation). None of the division’s sites received an administrative formal notice for reasons of non‑compliance of wastewater discharges. J3L Air emissions subject to increased monitoring comprise gases from surface treatment sites. A system was set up for capturing these emissions at source. Compliance with the limit values for air emissions imposed by the prefectural operating authorisation orders is verified by measurements carried out by external organisations. To take into account the capacity increases required for the future, work and investments are planned in 2023 to resize the gaseous waste capture and outlet system at one of the electroplating sites. This investment also has positive impacts on employee working conditions. The J3L group sites carrying out surface treatment are equipped with a “zero discharge” plant. Its principle allows the use of water in a closed circuit . After use in the various processes, the water is treated by two different technologies: ion exchange resins and an evapo‑concentrator. These technologies make it possible to reuse and recycle water in order to reinject it into the rinsing baths when it is of sufficient quality. Any discharges into the wastewater network or the natural environment are eliminated. A reduction in water consumption of nearly 75% compared to a traditional water treatment plant is thus observed.
