The ECB signed agreements with the European Cards Payment Cooperation, the Nexo Standards and the Berlin Group. The standards cover contactless payments, merchant and ATM transactions, and account-based transfers. Separately, major European banks are expanding moves to embed cryptocurrency trading into existing regulated platforms.

Youth social media curbs have little carbon-cut impact as servers keep running

Banning minors from using social media is unlikely to reduce carbon emissions because data centres and network infrastructure continue consuming power regardless of users\' ages, according to a report. Even if youth accounts are blocked, apps do not disappear and servers do not shut down. Critics also say overall screen time may not fall if teens switch to other content. They argue more direct measures should target data centres, platform energy use and video streaming.
