HRS, the corporate lodging and payment technology platform, announced that its Green Stay Initiative has now secured two “prominent” certifications. In late June, GUTCert, an accredited auditing organization in the European Union, conferred certification under the requirements of the International Standards Organization (ISO) 14067.

The auditing process also verified that Green Stay complies with the Greenhouse Gas Protocol (GHGP) Corporate Accounting and Reporting Standards. Both standards apply globally, said the announcement, “giving multinational corporate travel programs unrivaled assurance when they use HRS’ Green Stay Initiative to report, reduce and remove carbon emissions tied to corporate lodging.”

HRS is the only travel-focused technology company to hold both certifications, according to the announcement.

The Green Stay Initiative, launched in 2021, has achieved “remarkable traction” since its introduction, according to the announcement. The majority of the top 20 global hotel chains participate today, as well as more than 600 chains across more than 175 countries. Dozens of Fortune 500 companies, including prominent brands like Siemens, mandate use of the Green Stay Initiative for hotels seeking preferred supplier status in procurement exercises.

Tobias Ragge, CEO of HRS, said that as business travel volume accelerates across transient, meetings and long-stay segments, companies are increasingly motivated to find a credible, efficient solution to drive more sustainable hotel programs. “I’ve long believed,” he said, “that sustainability is the mega-trend impacting business travel this decade. Accordingly, HRS will continue investing in AI-infused technologies and services that help facilitate the reduction of emissions across the managed travel ecosystem.”
