On the heels of reports that food manufacturers are cleaning up supply chains to help combat global warming, Hyatt Hotels has recently announced plans to make hotels more efficient by 2020. Starting next year all new full-service hotels and renovations of Hyatt hotels will have to comply with stringent environmental building regulations, either LEED standards or equivalent certification. By 2020 all hotels will have to reduce water usage by 30 percent, cut back greenhouse gas emissions by 25 percent per square meter, and reduce waste that goes to the landfill by 40 percent.
