Marriott International said it has cut both water and energy use per room during the past four years. The company looks to reduce its properties' energy and water consumption by 20% by the end of the decade.
Since 2007, the company’s hotels have reduced their per-room water usage by 12% and cut their energy consumption by 4%, Marriott said in a companywide sustainability report.
Marriott also has reduced landfill waste per room at its Americas hotels by 10% during the past two years, the company said.
In June, Marriott led a group of 23 hotel companies that agreed to support an effort to standardize how to measure a hotel’s impact on the environment in the form of greenhouse-gas emissions.
The group is working with the International Tourism Partnership and the World Travel & Tourism Council on practices for calculating a property’s carbon footprint, and on metrics for disclosing and comparing emissions levels among hotels.
