C2 Hôtel is committed to sustainable tourism and has been recognized by the 1st international environmental label for Clef Verte tourist accommodations. This label focuses on the establishment's environmental policy, guest awareness, water, energy and waste management, and responsible purchasing. The C2 hotel's approach can be seen in the recycling of plastic (membership of the YOYO association), the implementation of a short purchasing circuit and the promotion of organic produce. Hospitality products have been replaced by solid room products (DAMANA brand) and individual bags have been eliminated. A project to install a beehive in the 12th arrondissement is due to be launched, and the C2 Hôtel is organizing a calendar of events focusing on sustainable development, with the spotlight on local producers (local producers' market within the C2 or workshops focusing on recycling).
