ISO 9001-certified hotels guarantee quality management, backed up by the ISO 14001 standard, which is based on the continuous improvement of environmental performance.

These establishments respect the principles of the standard in terms of environmental management, contributing to reducing to a minimum the effects of their activities on the environment and to permanently improving their environmental performance. In Paris, over a dozen IBIS hotels are ISO 14001-certified. As for Le Fouquet’s Barrière, it is one of the world's rare hotels to have three certifications - SA 8000, ISO 9001 and ISO 14001 - in addition to being the first in Europe to be awarded the Leading Green label.
