Sustainability isn’t just about saving money—it’s a driver of bookings and revenue.
In a previous article, we saw that sustainability, when managed properly, reduces costs without compromising the guest experience. But there’s another side to the story that’s becoming increasingly important: sustainability can also generate revenue.
Demand—from leisure travelers and, above all, corporate travelers—already demands and rewards sustainable hotels. When approached correctly, sustainability ceases to be an expense and becomes a selling point that fills rooms.
The question, therefore, is no longer just: “How much can my hotel save by being more sustainable?” But rather, “How much business can I gain if I can prove it?”
Travelers choose (and filter) sustainable options
Travelers no longer view sustainability as a bonus. According to Booking.com’s 2026 sustainability report, 85% of travelers say that traveling more sustainably is important or very important, and in 2025, more than 100 million nights were booked at independently certified accommodations. About one-third of travelers have shown a preference for sustainably certified accommodations. A crucial distinction: travelers value proof, not promises. Without data or verifiable certification, the “green” message is perceived as greenwashing and backfires.
The Corporate Client
More and more companies are incorporating ESG criteria into their travel and procurement policies, and their requests for proposals (RFPs) now require sustainability credentials as a prerequisite, not as an optional extra.
Corporate travel agencies filter their offerings using those same criteria: if a hotel cannot demonstrate its performance, it does not make the list of suppliers. And this segment is worth its weight in gold, because it involves recurring business with higher rates and less seasonal fluctuation. Therefore, failing to meet the sustainability requirement could mean losing the entire account.
That is why, from a business perspective, the key is to address sustainability in a credible and understandable way.
Sustainability as a Bid Screening Criterion
The same is true for the organization of corporate events and meetings. Organizers already include sustainability in their specifications and need to report the event’s carbon footprint to their own clients, so a hotel that certifies its venue and provides impact data wins bids over competitors who can only make promises but cannot back them up with data. Here, sustainability ceases to be a matter of image and becomes a business capability.
Think of it in terms of an RFP: two hotels with similar locations, comparable prices, equivalent meeting spaces, and rooms of a similar category. If one can demonstrate its sustainability performance and the other can only make general claims, the former has the upper hand. And in the group and events sector, where a single decision can result in bookings for dozens or hundreds of rooms and a significant volume of F&B, that advantage translates directly into contracts.
Without certification, you’re not visible
Certification also determines your visibility on sales channels. In 2024, under pressure from European regulations against greenwashing, Booking.com removed its own “Travel Sustainable” seal and now only displays—and allows users to filter by—accommodations with a recognized independent certification from a list of more than 60 legitimate certifications.
Google takes the same approach: it distinguishes between practices reported by the hotel itself and third-party-audited certifications, and reserves the “eco-certified” label in its search results for the latter.
And so, one by one, booking platforms and search engines are tightening the requirements for accommodations to market themselves as sustainable to travelers.
The implication is clear: self-proclaimed sustainability no longer matters in distribution; certified sustainability does. A verifiable credential is what makes your efforts stand out to someone who is about to make a reservation.
From Credential to Admission
Having the credentials is just the first step: the value comes when you turn them into a sales tool. To do that, follow these three steps: Make them visible where booking decisions are made—your website, your booking engine, and your channel listings; tell the story using concrete data rather than adjectives; and train your sales team to use the certification as a selling point in corporate and group negotiations. In short: whatever the operations team saves, the sales team needs to know how to sell.
The Role of Ecostars
The common thread linking travelers, businesses, and event organizers is the same: they all demand verifiable proof, not just a statement of intent. At Ecostars, we believe that hotel sustainability must, above all, be measurable. Because you can only properly manage what you understand.
Ecostars measures your hotel’s environmental, social, and governance performance, certifies it, and turns it into a communicable and comparable selling point. This way, your sales team approaches every RFP, channel listing, and negotiation with data that supports the sale. Sustainability—in addition to saving money—starts to generate revenue.
