The European Commission (EC) on Thursday laid out a detailed roadmap for a proposal to bar children younger than 13 from accessing social media and mandate that platforms improve their design to better protect minors.

The announcement comes as countries worldwide — including Australia, Spain, France, China, Turkey and the UK — have either implemented similar bans or have indicated they plan to amid growing concerns about how the technology affects kids.

The proposal, known as the EU KIDS Act, would block social media platforms from offering accounts to children younger than 13 and establish a bloc-wide minimum age of 15 for account creation. 

Children between 13 and 15 will only be able to access social media platforms if their guardians create “mini accounts” their kids can access through their parents’ accounts, according to an EC press release. The mini accounts will be regulated strictly, the press release said, and services will be required to limit social contacts and cap screen time to an hour a day.

Children under 13 will be entirely blocked from social media outside of parent-controlled tools designed to limit the use of the adult’s device to child-friendly video-sharing services. The onus will be on providers to create the tool and ensure it is simple to use, the press release said.

The proposal will not become law until EC officials win support from the European Parliament and member states. European countries have been broadly supportive of social media bans for young teens, giving the proposal a significant chance of being enacted.

“Today, our children are engaging with the most sophisticated technologies ever created,” Commission President Ursula von der Leyen said late Wednesday in a speech previewing the proposal. “Technology that was never created with their wellbeing in mind.”
