KEY POINTS
  • The EU's proposed ban on coal imports from Russia is not expected to take effect until August — a month later-than-expected.
  • Germany is one of the most skeptical nations when it comes to blocking energy supplies from Russia, but it's not the only one. Austria and Hungary, for instance, are also opposed.
  • Approving these sanctions has been a major challenge for the bloc given its high dependency on Russian energy.
"There seems to have been an effective German lobby to extend the phase-out period for existing coal contracts to four months," an EU official told CNBC.

The European Union's proposed ban on coal imports from Russia is not expected to take full effect until August — a month later than expected, two sources told CNBC Thursday.

Earlier this week, the European Commission, the executive arm of the EU, proposed the ban in the wake of mounting evidence of atrocities by Russian troops against Ukrainians in Bucha and other areas.
