Brussels - Hackers stole two million tonnes of polluting rights in a five-day raid this week on the European Union's carbon emissions trading system, an EU source said on Thursday.
The volume of carbon credits stolen in online action, which a European Commission spokeswoman was “possibly concerted”, represents just a fraction of global industrial greenhouse gas permits, but is potentially worth many millions of euros.
The scale of the theft, which involved five unnamed EU states, was revealed a day after Brussels shut all 27 national trading registries for a week, citing inadequate online protection.
Credits stolen just from the Czech Republic were worth seven million euros.
Fourteen of the 27 European Union states need to boost their online security to minimum standards, the spokeswoman said.
