The European Union is set to propose a voluntary 15% cut in natural gas use by member states starting next month on concern Russia may halt supplies of the fuel.
The goal would be embedded in a regulation accompanying a demand-reduction plan the European Commission is scheduled to unveil Wednesday to cope with a potential full cutoff by Moscow. The measure also would include a mandatory trigger if the situation worsens and voluntary curbs are insufficient, according to three EU diplomats with knowledge of the matter.
