Online reviews in tourist accommodations increasingly influence booking decisions and the reputation of companies and destinations. In response to the rise of fake reviews and AI-generated content, the European Union is promoting a Code of Conduct that encourages verified reviews, platform transparency, and greater trust in digital tourism. This analysis examines the impact of this new European framework and its relationship with verifiable sustainability and the credibility of the tourism sector.
The digital tourism economy increasingly relies on information infrastructures generated on online platforms. Among them, online reviews of tourist accommodations have become one of the most influential factors in travel decision-making, business reputation, and commercial visibility within digital distribution channels.
However, the exponential growth of these reviews has also highlighted a structural problem in the digital tourism ecosystem: the difficulty of distinguishing between authentic opinions, incentivized content, or fraudulent reviews.
In this context, the European Commission has promoted the so-called Code of Conduct for online reviews and ratings in tourist accommodations, an initiative aimed at strengthening market transparency and establishing a reference framework for the responsible management of digital reviews.
Beyond its voluntary nature, the code represents a significant step toward consolidating standards of informational integrity in digital tourism, aligned with regulatory expectations and the growing demand for transparency from consumers.
The Code of Conduct is part of a broader evolution of the European regulatory framework on consumer protection in digital environments.
In particular, Directive (EU) 2019/2161, known as the Omnibus Directive, introduced specific obligations for companies that publish consumer reviews. Among them, we highlight:
The Code of Conduct promoted by the European Commission is conceived as a sectoral self-regulation instrument that translates these regulatory principles into operational practices applicable to the digital tourism ecosystem.
Its approach is structured around three fundamental pillars, which are:
Taken together, these principles aim to strengthen the credibility of the online review system, an element that directly affects consumer trust and competition among tourism operators.
One of the most relevant characteristics of the Code of Conduct is its development through a collaborative process among key stakeholders in the European tourism sector.
Among the signatory organizations are some of the main digital intermediation platforms in tourism, such as Booking.com, Expedia Group, Tripadvisor, and Airbnb, whose activity influences millions of booking decisions each year.
HolidayCheck also participates, a digital platform specialized in the German-speaking market, which for more than two decades has applied human moderation systems and artificial intelligence technologies for review verification.
From the travel technology field, the code is supported by eu travel tech, an association representing companies in the travel technology sector, including online travel agencies, metasearch engines, and digital platforms.
The European hospitality sector is represented by HOTREC, an organization that brings together national associations of hotels, restaurants, and similar establishments in 36 European countries.
Sectoral and territorial organizations have also joined, such as EFCO&HPA, a representative entity of the European camping and holiday park sector, the Romanian Hotel Industry Federation (FIHR), and Athens Development Organization, responsible for the tourism promotion strategy of the Greek capital.
The diversity of signatories reflects the systemic nature of the challenge. The reliability of online reviews does not depend solely on platforms, but on the entire set of actors involved in the generation, moderation, and use of information in the digital tourism market.
The debate on the authenticity of reviews connects with another structural transformation in contemporary tourism: the growing demand for verifiable evidence in sustainability.
For years, environmental communication in the sector has relied on generic messages or loosely defined labels. However, increasing regulatory and reputational pressure against greenwashing is driving a transition toward models based on data, indicators, and independent verification.
This shift responds to a growing demand for comparable and traceable information, both from travelers and from investors, public administrations, and international organizations.
In this context, tourism sustainability certifications play a relevant role by providing structured evaluation frameworks that make it possible to transform declarative commitments into verifiable and measurable criteria.
Certification systems such as Biosphere, aligned with the United Nations Sustainable Development Goals (SDGs) and with reference frameworks used in the ESG field, help strengthen the credibility of sustainability strategies of tourism companies and destinations.
From a systemic perspective, reviews and certifications fulfill complementary functions within the trust ecosystem of digital tourism.
The combination of both dimensions makes it possible to build a more robust trust architecture, in which the user experience is complemented by independent verification processes.
The implementation of the European Code of Conduct for online reviews reflects a structural trend in the governance of digital tourism.
Trust in the tourism market no longer depends solely on reputation or corporate communication. It is increasingly based on verification systems, informational transparency, and comparable evaluation frameworks.
In this context, initiatives such as the European Code of Conduct for online reviews constitute a relevant step toward consolidating standards of trust in the digital tourism economy.
