Measuring lodging's environmental impact is less straightforward than for air travel or car rental. All three contribute to a business trip's carbon footprint, but hotels also use lots of water and electricity, and deal with a lot of trash. When deciding which properties to work with, most companies don't consider environmental data. Many, though, ask for it. More than half of IHG's business accounts last year sought such information. To meet the need, it's been working on new, customized reports for certain corporate clients.
Marriott International also is building out mechanisms for sharing sustainability data . . .
