The internet, especially social media, plays a crucial role in children’s lives, while, at the same time, subjecting them to a growing number of risks. In response, the EU has enacted various laws and initiatives to safeguard children online in recent years. More recently, several Member States have drawn inspiration from Australia’s social media ban for under 16-year-olds and have begun advancing national restrictions on children’s access to social media and/or smartphones. Much like the regulatory fragmentation that prompted the adoption of the Digital Services Act (DSA), these developments raise concerns about divergent national approaches within the EU single market. Thus, the Commission is currently exploring the possibility of an EU-wide social media ban for children, advocating for a harmonised approach that ensures uniform protections across the Union.
