Sustainability In The Hotel Industry Statistics

Hotels are getting pulled in two directions at once. While $1.5 billion global market value for sustainable tourism initiatives and a $9.8 billion smart buildings market signal major momentum, guests and business travelers increasingly expect action, with 63% of consumers and 49% of business travelers factoring sustainability into their choice, and reporting that can’t hide behind cost increases as 91% of hotels expect regulation to raise operating costs.

Sustainability is no longer a side concern for hotels. A 2026 snapshot worth paying attention to is that 63% of consumers factor sustainability into their hotel choice, yet only 32% of hotels name water conservation as a top priority. The gap between what guests value and what properties prioritize gets even sharper when you look at costs, market momentum, and the operational fixes that can cut energy, water, and emissions.
