In the spring of 2026, Michelin brought one of the most ambitious chapters in its modern history to a close. The Green Star—a symbol of sustainability in gastronomy that was intended to change the way the world rates restaurants—has come to an end after just six years.
Without a major campaign, without ceremony, but rather with an explanation that must be read between the lines, the system—which was intended to be the culinary world’s response to the climate crisis—proved difficult to grasp, inconsistent and, in some respects, even misleading. As official statements from the Michelin Guide and analyses in the gastronomic press show, the problem lay not with the idea itself, but with the fact that it was impossible to measure it globally and reliably.
When Michelin introduced the Green Star in 2020, it sent a clear signal: the world’s most influential gastronomic guide wanted to assess broader social impact alongside flavour and concept. Restaurants that “inspire a more sustainable approach” were to receive further visible recognition alongside the classic red Michelin stars. At a time of growing pressure for sustainability in gastronomy, this seemed a logical step—a symbolic endorsement of a trend that had long been shaping fine dining from Copenhagen to San Sebastián. Michelin thus added a new layer to its communication, one which, however, stood outside its traditional evaluation framework from the outset.
It wasn’t long before the first problems arose. As both internal and external analyses show, the Green Star was not based on a traditional audit, but rather on a combination of questionnaires, information provided by restaurants and inspectors’ assessments, without any detailed scrutiny of supply chains. Critics pointed out that such a system naturally favours compelling narratives over hard data—rooftop gardens, in-house fermentation or local farms became visible symbols of sustainability, without it being possible to objectively compare their actual environmental impact. As the British publication Restaurant Online summarises, “the biggest problem was precisely the absence of a verifiable methodology and the risk that the awards were based more on narrative than on measurable results”.
In practice, this meant a fundamental shift in how restaurants began to communicate sustainability. Instead of systemic change, the “impression of sustainability” was often optimised. This phenomenon, which some experts referred to as the “greenwashing effect”, was further exacerbated by the fact that the Green Star did not draw clear boundaries between what was “sufficiently sustainable” and what was not. As other analyses, such as those on the Restaurant Ranking website, have pointed out, “differences between regions, energy mixes and local agricultural systems made it impossible to create a universal benchmark that would be fair across the more than sixty destinations covered by the Michelin Guide”.
On top of this came another fundamental paradox: the very essence of fine dining. By its very definition, luxury gastronomy is a system with high material and energy requirements—from staffing ratios and the logistics of sourcing ingredients to working with exclusive products. In this context, sustainability ceases to be a simple question of “local versus non-local” and becomes a complex equation in which aesthetics, economics and environmental impact intersect. It is precisely here that it has become apparent that a simple symbol in the form of a star is not enough to capture such a complex reality.
The end of the methodology
A major turning point came when sustainability became not only an ethical but also a regulatory issue. In Europe, calls began to grow for a more precise definition of environmental claims and more transparent communication of so-called “green claims”. In this context, it became apparent that the Michelin Guide’s Green Star occupied a kind of liminal space: it was not a certification, yet nor was it purely editorial content within the prestigious guide. As Gwendal Poullennec, international director of the Michelin Guide, said in an interview with Le Chef magazine, “the Green Star was never intended to be a certification in the administrative sense of the word. Such certification presupposes a completely different—and, in fact, almost opposite—approach to the one we take,” he explained at the beginning of June this year, by which time it had already become clear that the Green Star could not be maintained in its original sense.
It was precisely this ambiguity that became the key problem. Restaurants began using the Green Star as a marketing tool, while some members of the professional community criticised it as an insufficiently verified symbol. Michelin thus found itself in a situation where its most prestigious guide was assessing an area that its traditional inspection model was unable to audit in detail. The result was growing criticism and internal tension between ambition and methodology.
In the spring of 2026, Michelin therefore implemented a fundamental change. The Green Star was abolished and replaced by a new editorial concept, “Mindful Voices”, which no longer functions as an award but as a platform for the stories of people from the worlds of gastronomy, hospitality and winemaking. This shift is also confirmed by the official Michelin Guide report, which emphasises that the aim is no longer to certify, but to tell stories and showcase practices without claiming to provide a hierarchical ranking.
From the restaurants’ perspective, this represents a fundamental change. A generation of establishments has emerged that has invested in sustainability not only in terms of marketing but also in terms of infrastructure—ranging from their own farming projects to a complete overhaul of kitchen operations and supply chains. Among the most striking examples are Silo, regarded as a pioneer of zero-waste gastronomy; Azurmendi, run by head chef Eneko Atxa, which is often cited as one of the most comprehensive examples of an environmentally designed gastronomic establishment; and the now-closed Amass, whose founder, Matt Orlando, was one of the most vocal advocates for systemic change in the areas of food waste and circular gastronomy. For such establishments, the Green Star represented not only symbolic recognition of their long-term efforts, but also a significant reputational and marketing tool. Its abolition therefore raises an uncomfortable question: what does a “sustainable restaurant” actually mean today, if it is no longer defined by any global standard?
What remains after the Green Star
Ultimately, the story of the Green Star is not one of the failure of a single award, but of the limitations of the entire system of sustainability assessment in gastronomy. Michelin attempted to apply the logic of the stars—clear, hierarchical and comprehensible—to a field that is, by its very nature, local and methodologically elusive. And it is precisely this clash that has proved to be the key problem.
As reactions from parts of the gastronomic community show, true sustainability is now moving in a different direction: less about symbols, more about data, processes and concrete changes in operations. Less about visibility, more about infrastructure. And perhaps even less about global rankings, which tend to oversimplify, and more about local systems that better understand the context.
The Green Star has not disappeared because sustainability has ceased to be important. It has disappeared because it has become clear that it cannot be reduced to a symbol without losing its true essence.
