Corporate travellers, sharpen your pencils or at least your sustainability procurement spreadsheets. A new global benchmark has marched onto centre stage, promising to give the hotel sector the environmental shake-up many have argued was well overdue. Advito, one of the more assertive voices in corporate travel consulting, has launched what it calls the Hotel Sustainability Index (HSI), a detailed, data-driven framework designed to finally make sense of the hotel industry’s notoriously inconsistent environmental reporting.
At its core, the HSI addresses a truth long whispered in travel corridors: despite the marketing, recycled keycards, and earnest green signage about towel-reuse programs, there has never been a reliable, global way to compare hotels’ environmental footprints. Advito is attempting to change that with a heavy dose of methodology, rigour and, importantly, transparency.
“Travel buyers have been asking for a better way to understand and measure hotel sustainability,” said Julien Etchanchu, Global Lead for Advito’s Sustainability Consulting practice. “With the HSI, we’re giving our clients an authoritative tool based on actual hotel data and real-world conditions. It helps organisations see where the meaningful differences are and how to act on that information.”
According to Advito, more than 76 per cent of travel buyers now embed sustainability goals into corporate policies, which means environmental blind spots are no longer something companies can afford to tolerate. Enter the HSI, a system that scores hotels on a 100-point scale across six core pillars: CO₂ emissions, water consumption, energy usage, eco-certifications, transparency, and a catch-all category that examines initiatives such as single-use-plastic avoidance and recycling efforts.
What sets the index apart, however, is its layered scoring model. Hotels are not only judged on absolute performance (those unavoidable tonnes of emissions and litres of water), but also relative performance, a nod to the fact that a property operating in a high-carbon electricity grid shouldn’t be compared harshly with one running on hydro-powered bliss. A hotel in a challenging region may score modestly on raw emissions but climb the ladder when benchmarked against local peers facing similar constraints.
True to its sustainability-consulting DNA, Advito has tied transparency to reward. Properties that willingly disclose operational data earn disclosure credit. Those that prefer to keep their environmental cards close to their chest are assessed using regional averages, anchored in the industry-standard HCMI framework and Advito’s own ISO-certified GATE4 emissions methodology. For travel managers long frustrated by guesswork, this alone will feel like rain after drought.
The index is already woven into Advito’s proprietary sourcing tool, allowing corporate travel programs to evaluate preferred hotel suppliers with sustainability in mind, not as an afterthought, but as a material factor in RFPs. For an industry where environmental claims often drift between exuberant and opaque, this kind of comparative rigour marks a welcome shift.
Advito also hints that the HSI is only the beginning. As the dataset expands, the consultancy plans to introduce point-of-sale nudging to encourage travellers themselves to make more sustainable hotel choices. It is, Etchanchu suggests, about building a future where sustainability becomes second nature rather than a noble aspiration.
“Companies want to align their travel programs with climate goals, but until now the data just hasn’t been there,” he said. “HSI allows them to differentiate between hotels that simply meet a baseline and those demonstrating continuous improvement and operational accountability, giving them better insight into the sustainability of their hotel partners and creating a foundation to guide their travellers towards more responsible choices.”
In other words, hotel sustainability, once a potpourri of inconsistent claims and charming brochures printed on “recycled” paper, is about to meet a more disciplined, data-driven era. And for an industry grappling with its environmental obligations, it is arriving not a moment too soon.
