Tourism, as a worldwide socioeconomic phenomenon, has experienced profound changes driven by the Fourth Industrial Revolution—marked by the merging of disruptive technologies such as Artificial Intelligence (AI), Big Data, the Internet of Things (IoT) and cloud computing. These innovations are transforming the tourism industry by enabling more personalised experiences, improving operational efficiency and promoting sustainable practices. Digital transformation in tourism is more than just adopting new tools; it represents a fundamental shift in how destinations are managed, marketed and experienced. As the sector continues to evolve, it becomes increasingly important to examine the challenges and opportunities that come with integrating technology into its core functions, especially in the development and use of tourism data spaces. In the post-COVID-19 world, the industry aims not only to recover but to reimagine its growth strategies in line with societal priorities around health, sustainability and resilience. The integration of smart technologies plays a crucial role in managing new challenges as tourism flows and shaping visitor behavior, thereby supporting the development of sustainable and resilient destinations.

This technological transformation has reshaped travelers’ expectations, who now seek hyper-personalised, sustainable and seamless experiences. At the same time, it presents complex challenges for destination managers, who must balance competitiveness, resource conservation, relations between residents and tourists, and social inclusion. Addressing these issues requires a shift from traditional, fragmented, siloed methods to a more integrated, data-driven approach, where data is viewed as a strategic asset and a catalyst for innovation. The European Union’s vision for data spaces offers a transformative framework for how data is accessed and used across different sectors, including tourism. Data spaces aim to eliminate data silos, enabling seamless and secure data exchange to unlock new opportunities for innovation and value creation. Developing tourism data spaces is particularly vital since tourism is an information-intensive sector, relying heavily on data for planning, decision-making and enhancing the traveler experience. While digital solutions have significant potential, much of this remains untapped. By enabling secure and trustworthy data sharing among stakeholders such as tourism boards, hospitality providers, transportation services and local businesses, data spaces can foster a more comprehensive and agile approach to tourism management.

Unlocking the Power of Data: Transforming the Landscape of Tourism

The modern tourist functions as a digital prosumer, creating data through every interaction—from online bookings to social media reviews—and consuming information to make better decisions. According to the European Commission (2022), 89% of European tourists use mobile apps during their trips and 76% view real-time personalised recommendations as essential. This shift has elevated data to a key strategic asset in the tourism industry, with an estimated annual value of €152 billion for the European tourism economy. Access to real-time information about visitor flows, preferences and behaviors allows destination managers to better allocate resources, reduce congestion and improve overall visitor satisfaction. Additionally, integrating socio-spatial data—both tangible and intangible—can provide a deeper understanding of landscape values, supporting sustainable, long-term planning.

However, the full potential of this data remains largely untapped because of fragmented data ecosystems, where information is stored in isolated silos across booking platforms, public authorities, social networks, transport systems and local tourism stakeholders. This disconnection hampers destinations’ capacity to offer integrated services and to proactively address crises like over-tourism or climate-related disruptions. Therefore, creating a sound European tourism data space is considered a priority to drive innovation, enhance competitiveness and promote sustainability in the tourism industry, on par with advancements in mobility.

Overcoming these challenges necessitates the development of an interconnected data ecosystem that enables secure, reliable and scalable data sharing. Tourism data spaces provide a solution by creating a framework where data can be securely shared, accessed, reused and analysed, promoting collaboration, innovation and better-informed decision-making. However, tourism data spaces are more than just technological infrastructure; they are complex ecosystems that require careful attention to governance, security and interoperability. Ensuring data security and privacy is especially critical given the rise of cyber threats and strict data protection laws. Building trust among data providers and users depends on implementing robust security measures, transparent governance structures and compliance with regulations such as GDPR.

Ensuring seamless interoperability among diverse data sources and systems is essential for the success of tourism data spaces. To achieve this, adopting standardised data formats, developing common vocabularies for semantic interoperability and implementing open APIs are crucial steps.

A shift toward low-carbon tourism, driven by big data, has the potential to transform the traditional tourism business model, paving the way for a more sustainable and intelligent future for the tourism supply chain. However, increasing reliance on digital technologies may also create feelings of alienation and isolation among tourists seeking authentic experiences and direct connections with local cultures. Therefore, forward-thinking tourism cities should look beyond sustainability alone, adopting a holistic approach that considers emerging trends, including the importance of encouraging both tourists and residents to periodically disconnect from digital media through digital detox routines to support mental health and resilience. Additionally, integrating AI and IoT can lead to the development of smarter, visitor-centered destinations. By leveraging real-time data and AI-driven insights, tourism services can be enhanced through greater personalisation, accuracy, innovation and inclusivity.

Revolutionising European Tourism: The Transformative Power of the Common European Tourism Data Space

The importance of Common European Tourism Data Spaces (ETDS) extends beyond just technological innovation—they signify a fundamental shift towards collaborative data governance. Their adoption can help address key paradoxes in the tourism sector, such as overcrowding in popular destinations like Barcelona and Venice and rural depopulation, by enabling data-driven redistribution of visitor flows. Tourists are increasingly seeking authentic experiences that reflect their values of ecological responsibility and cultural appreciation. Meanwhile, destinations recognise that adopting sustainable practices can offer long-term advantages, including greater resilience to climate change, the preservation of natural resources and economic diversification. Digital technology has the potential to greatly influence the sustainability of tourist destinations—both positively and negatively—and this research aims to explore and clarify these impacts.

The merging of digital technologies with sustainability principles offers a valuable opportunity to reshape the tourism industry into a more environmentally sustainable and economically resilient model.

The long-term attractiveness of a tourism destination is essential for its ongoing growth, requiring continual innovation and quality enhancements to stay competitive in the global market. Additionally, ETDS serves as the technological foundation of smart tourism destinations—a concept endorsed by UNWTO (2021)—which combines technology, sustainability and inclusivity to foster sustainable and vibrant tourism experiences.

Within this framework, DEPLOYTOUR was approved — the Common European Tourism Data Space – under the Digital Europe Programme. This is a three-year project led by AnySolution, with a consortium of 40 entities from 13 member states representing the entire tourism value chain. Its main objective is to develop a trusted and secure Common European Tourism Data Space to improve data access and sharing, fostering innovation and new business models aimed at boosting tourism competitiveness and sustainability by supporting digital and green transitions while empowering SMEs and DMOs in their transformation.

The implementation of the Common European Tourism Data Space will be evaluated through five pilot projects targeting various tourism destinations and types, such as sun & beach, mountain, MICE and cultural tourism. Facilitating data sharing among different tourism stakeholders will boost destination competitiveness and contribute to a seamless tourism experience, ultimately enhancing visitor satisfaction.
