Corporate lodging platform HRS' Green Stay Initiative, a programme that offers standard data points for hotels to detail sustainability offerings, has earned certification from the International Standards Organization, HRS announced on Wednesday (10 July).
Specifically, Green Stay was certified under ISO 14067 standards by European auditing organisation GUTCert, which also "verified that Green Stay complies with the Greenhouse Gas Protocol Corporate Accounting and Reporting Standards," according to HRS, which added that both certifications apply globally.
Launched in 2021, Green Stay is an offering that assigns sustainability scores, calculated by HRS using a proprietary formula, to hotels for display in booking channels. Several global hotel chains have agreed to participate, as have independent hotels.
Germany-based conglomerate Siemens Corp. in recent years became the first corporate client to require all hotels in its programme join Green Stay, and HRS on Wednesday said "dozens" of Fortune 500 companies since have followed suit, without identifying any.
HRS said it is the first "travel-focused technology company" to hold both the ISO and GHGP certifications.
"The ISO and GHGP certifications mark yet another point of confidence for corporations and hoteliers working with the Green Stay Initiative today, and further underscores the benefits of our platform-based approach to reduce and remove emissions while reporting accurately," HRS CEO Tobias Ragge said in a statement.
"I've long believed 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."
