Why does every hotel look green? And why many aren’t

There are more than 200 eco-certification schemes operating in hospitality globally. A market with that many labels eventually teaches travelers to trust none of them.

The sustainability page is the third tab on the hotel website. It loads with a photograph of a solar panel. Below is a paragraph about the hotel’s commitment to the planet. Below that, three logos: a green leaf, a blue wave, and the earth. Each has a name underneath it. None of the names will mean anything to the traveler who reads them.

The common assumption is that certification means something. The logo on the website represents an independent assessment of environmental performance, verified by someone with the expertise and authority to confirm it. Booking a certified property is a meaningful act.

It depends entirely on which certification it is. And the traveler has almost no way to know.

THREE HOTELS. THREE RESPONSES TO THE SAME PRESSURE.

Sustainability has become hospitality’s most crowded language — and one of its least understood. Every hotel now has a sustainability page. The certification market that has grown alongside it has produced three recognizable types of property, each managing the green question differently.

CERTIFICATION AS MARKETING

The hotel with the logos and the solar panel photograph

The most common type. A property that has acquired one or more certification badges — typically through a self-assessment process or a scheme with minimal independent audit requirements — and has made those badges central to its marketing. The property may have made genuine but limited operational changes: towel-reuse programs, LED lighting, and a food-waste composting initiative. These are real improvements.

They are also the baseline of what most hotel operations now require, legally or otherwise, in many jurisdictions. The certification communicates something considerably more than these incremental changes justify. The gap between what the badge implies and what the operation has changed is not necessarily the result of deliberate dishonesty. It is the result of a certification market that allows self-assessment and does not require disclosure of what specifically qualified the property for the standard.

SIGNIFICANT INVESTMENT, POOR COMMUNICATION

The hotel has done the work and cannot explain it.

Less common but editorially important: a property that has made significant capital investment in sustainable infrastructure — solar thermal systems, greywater recycling, a supply chain genuinely sourced within a defined local radius, documented biodiversity commitments on working land attached to the property — but that communicates this poorly, inconsistently, or not at all. Some properties in this category have deliberately avoided certification because they regard the available schemes as insufficiently rigorous.

Others have simply not invested in communicating what they have built. The result is a phenomenon researchers have named greenhushing: the deliberate understatement of genuine sustainability commitments. The property that has done the most may be the least visible in a market that rewards signaling over performance.

ACCREDITED CERTIFICATION WITH OPERATIONAL DATA

The hotel whose badge means something specific.

The smallest category. A property certified by a body accredited through the Global Sustainable Tourism Council, meaning the certification process itself has been independently verified to meet international standards and that publishes operational data alongside the badge. Not the badge alone. Energy consumption per occupied room. Water use per guest per day. Waste diversion rate. Percentage of food sourced locally. 

Numbers that can be compared against industry benchmarks and tracked over time. Green Key, with more than 9,000 certified establishments globally as of July 2025 and a mandatory on-site audit as part of its process, is the most widely deployed scheme in this category. EarthCheck and Travelife operate to comparable standards. Properties certified under these schemes are not automatically perfect. They are, however, certifiable — the claim can be verified.

WHY THE MARKET CREATED ALL THREE

There are now more than 200 sustainability-related certification schemes operating in hospitality globally. They have different standards, audit requirements, renewal cycles, and definitions of sustainability. Some require independent on-site verification. Others require a self-assessment form and a fee. A traveler looking at three green logos on a hotel website has no reliable way to know which category each one falls into.

In March 2024, Booking.com removed its Travel Sustainable label following criticism from the Netherlands’ Consumers and Markets Authority, which found the badge potentially misleading because it was based largely on self-reported data. 

A Journal of Hospitality and Tourism Management study published the same year found that 48% of hotel booking platform users described sustainability information as an overload, 47% found it not easily interpretable, and 41% deemed it unnecessary. YouGov research from 2025 found that 42% of travelers had already encountered exaggerated environmental claims from hotels.

The EU’s Green Claims Directive, which came into force in 2024, prohibits vague environmental claims without substantiation. The Netherlands saw a 48% reduction in greenwashing cases following its own regulatory action. Outside Europe, enforcement is lighter, and the market remains largely self-regulating.

THE GREENHUSHING PROBLEM

Greenwashing gets the attention. Greenhushing is the equally important problem running in parallel. The properties that have invested most seriously in genuine sustainability are sometimes the least visible, because they have declined to acquire badges they regard as insufficiently rigorous, or because they have simply not invested in communicating what they have built. A traveler who only books certified properties may systematically miss some of the best-performing hotels at their destination.

WHAT TO ACTUALLY LOOK FOR

Three questions change how the sustainability page reads.

First, is the certification on an independently audited scheme? The GSTC maintains a public list of accredited certification bodies. If the scheme on the hotel website is not on that list, its standard is whatever the certification body has chosen to set for itself.

Second: does the hotel publish operational data? Energy per room, water per guest, waste diversion rate. Not targets. Numbers. A hotel that genuinely performs well publishes its performance because performance is its strongest argument. A hotel that only publishes commitments may not yet have the numbers to back them up.

Third: What does the certification require to earn? A property that mentions towel reuse and LED lighting is describing the baseline. A property whose sustainability page details its energy sourcing, water recycling system, and verified local supply chain is describing what it has actually built. The language of the page is the most reliable indicator of what lies behind it.

WHAT THIS STORY WANTS YOU TO KNOW

Green certification in its current form is as much a signaling problem as a sustainability problem. Over 200 schemes with no common standard have made the market less legible, not more. The presence of a badge does not tell you what the badge requires.

The most reliable indicator of genuine sustainability is operational data: energy per room, water per guest, waste diversion rate, not certification status. A hotel that publishes these numbers has something to show. A hotel that only publishes commitments may not yet have the numbers to back them up.

Greenwashing gets the attention. Greenhushing is the equally consequential problem running in parallel. The properties that have invested most seriously in sustainability are sometimes the least visible in a market that has rewarded signaling over performance.

Hotels don’t become sustainable because they display a badge. They become sustainable because their operations can withstand scrutiny.
