M Social Hotel Paris was recently awarded the Green Key label for the second time in 2026, reinforcing its commitment to sustainable tourism and responsible hospitality. The Green Key label, developed in France by the association Teragir, recognises establishments that demonstrate ongoing dedication to environmental stewardship and sustainable development. M Social Hotel Paris joins 3,035 establishments across France in adopting eco-conscious practices that benefit both guests and the planet.

This achievement reflects a series of initiatives undertaken in collaboration with key partners. Through Dripdrop, the hotel provides umbrella stands for guests in the lobby. Across Millennium Hotels & Resorts properties in the United Kingdom, France, and Italy, umbrella rentals between January and August 2025 helped fund the planting of 4,181 trees in Mozambique and supported the collection of 25,074 plastic bottles.

In alignment with circular economy principles, Les Alchimistes transforms organic waste from both the hotel restaurant, @papillonsandco, and the staff canteen into nutrient-rich compost. In 2025 alone, 4,681 kg of food waste was converted into 845 kg of compost, helping reduce landfill contributions and supporting sustainable agriculture.

Other sustainability initiatives include SapoCycle, where used soaps by L’OCCITANE Group are collected and recycled. In 2025, 156 kg of soap were recovered, enabling the redistribution of 1,500 soaps to people in need. The hotel also supports biodiversity through Un Toit Pour Les Abeilles, sponsoring a beehive whose second Prairie Honey harvest is now available in the hotel restaurant.

The Green Key certification is a testament to the hotel’s ongoing dedication to environmental responsibility and social impact. It also underscores the power of collaboration with like-minded partners, encouraging M Social Hotel Paris to continue innovating and strengthening its sustainability practices for the benefit of both guests and the wider community.
