Brussels: European Union countries agreed on Friday to restrict the circumstances in which the bloc can suspend its carbon emissions fee on imports, potentially helping to provide more certainty for low-carbon investments in the bloc.EU economy ministers backed the plans with majority support, despite countries including Slovakia, Romania and Lithuania declining to support them.The EU carbon border levy imposes a fee on the emissions associated with imports of goods, including fertilisers, steel and cement. The world-first policy aims to protect European industries from being undercut by cheaper, more polluting goods from abroad.
