The European Union is leading the way in virtual world development, with an estimated market value of €800 billion by 2030. The EU’s approach focuses on human-centered and interoperable virtual worlds that support development while respecting EU values and fundamental rights. The EU’s definition of Web 4.0 emphasizes the seamless integration of digital and real objects and the enrichment of human-machine interactions.
In line with the European vision, virtual worlds could lead the development of smart cities. The European Union is making significant investments in basic infrastructure through projects such as Destination Earth and Local Digital Twins and European Digital Twin of the Ocean. Focusing on infrastructure is an important step towards realizing the Metaverse vision.
