A "green hotel" is an environmentally friendly accommodation that implements sustainable practices to reduce its ecological footprint. These hotels often use energy-efficient systems, recycle waste, and conserve water. They may also source local and organic products for their restaurants and promote eco-friendly transportation options for guests. Many green hotels participate in certification programs, such as the LEED (Leadership in Energy and Environmental Design) or Green Key programs, which recognize their commitment to sustainability. By choosing a green hotel, travelers can enjoy their stay while supporting efforts to protect the environment and promote responsible tourism.
