GRESB 2023: Mercialys achieves second place in the benchmark

GRESB1, which assesses the Environmental, Social and Governance (ESG) practices of real estate companies around the world, has once again recognized Mercialys, which has consolidated its position as a leader for sustainable development and maintained its secondplace ranking in its category for listed retail property companies in Europe. These excellent results reflect the Company's CSR commitments and performance levels.

Mercialys achieved a rating of 89/100, significantly higher than the average level for GRESB respondents of 75/100 in 2023. The Company also maintained its Green Star status, the benchmark's highest level of recognition, for the seventh consecutive year.

Mercialys is recognized specifically for its integrated management of CSR at the heart of the Company's strategy. Illustrating this, it achieved the maximum ratings in the "management" and "objectives" categories, taking into account the ambitious objectives set as part of its CSR strategy 4 Fair Impacts for 2030.

Mercialys also recorded progress with its CSR performance levels, particularly in terms of the certification of its assets, greenhouse gas emissions and waste management. These results highlight the quality of the actions taken consistently by the Company across its shopping center portfolio around these three strong pillars from its CSR strategy. Learn more about Mercialys' CSR strategy, actions and results in the 2022 CSR Report.
