Staying at a hotel requires a lot of resource usage. One of the biggest reasons for this is that hotels have a new person staying in the room each night, and constant travel through the building, so they have to spend a lot of money on cleaning products, washing sheets and pillowcases, and running the baths and showers. Travelers are often reminded that they can save some water, as well as save the hotel some money, by not having towels washed when not necessary during multiple day stays.
Hilton provides several types of sustainability features. Their website on sustainability mentions specific targets for reducing carbon usage, greenhouse gas emission, and water usage. This is a helpful feature since it provides a comparison that can be applied to other hotels. The Hiltons I have stayed at were relatively upscale, so a percentage drop in resource usage here could have more impact than an initiative of a cheaper hotel.
Looking up the cheaper hotel chain Motel 6 reveals that it is one of several chains which the company Accor manages. Accor also controls the Sofitel, Novitel, and Studio 6 chains. Accor installs sustainable lighting, recycling fluorescent bulbs and switching over to compact fluorescents. Older fluorescent lamps contain dangerous chemicals, so a professional must dispose of them. Motel 6 offers Ecolab laundry detergent. The motel installs efficient water faucet aerators, and it buys sustainable power generated by wind turbines.
Days Inn is another favorite for travelers on a budget. It turns out Days Inn, Super 8, Travelodge, and several other chains are owned by the company Wyndham. Wyndham provides information about its green initiatives, including some unique features. The hotel staff uniforms are made from recycled plastic bottles, which saves a huge amount of energy. Not sure how comfortable these are or how they hold up to wear and tear versus other hotel staff uniforms, probably polyester. The uniform initiative has the potential to reduce power and water usage in manufacturing by a great deal in any company that requires uniforms.
