More hotels have seen the benefits to going "green," according to reports in the San Francisco Chronicle. Both new and established hotels are beginning to implement green in one way or another. There is a push towards cutting toxic hazards to staff and guests, saving money on energy bills, cutting back on pollution, or just winning points for sensitivity.

To read their goals, many hotels are implementing a cardkey system, already popular oversees, that starts or stops power to a guests room when they enter or leave, saving on energy. Laundry facilities will also begin using simple soap and water to wash bedding and housekeeping will employ citrus-based cleaning products to freshen carpets and drapes. Toilets will also be low-flow fixtures, saving on water.
