Eco-friendly hotel initiatives are growing increasingly popular, and these days many hotels are being recognized for their efforts by organizations such as LEED (Leadership in Energy and Environmental Design).

One of our favorite LEED-certified hotels is The Orchard Hotel, which was at the forefront of this movement. Among the very first LEED-certified hotels in San Francisco, the Orchard uses chemical-free cleaning products -- among many other impressive green practices.
