The Central Statistics Office (CSO) said it is working to clarify figures provided by Aughinish Alumina relating to the company’s exports to Russia.Minister for Enterprise Peter Burke on Tuesday claimed that figures sent by the Co Limerick-based operation to the national statistics body were wrong.The Irish Times on Saturday reported that 83 per cent of Irish alumina went to Russia in the first quarter of this year, with 0.6 per cent going to the EU. Burke said the true figure was about 45 per cent, with another 45 per cent going to the EU and other countries.In response to queries, the Department of Enterprise said it was “aware that a discrepancy in volume was presented in the export figures by Aughinish Alumina”. A spokesman said the company has been contacted by the department and “is now seeking to rectify this matter with the respective State bodies”.The CSO, which compiled the statistics, said on Tuesday afternoon it has yet to receive any amendments to the export figures. Such data is provided by the customs authority based on information provided by traders, a spokeswoman said.She said “traders are required to submit accurate goods exports data under EU regulation” and that statistics are “subject to regular revision through a standard process”.“The CSO is currently seeking to establish if there are revised figures for this category with the customs authority, which is the source of this data.”In March, an Irish Times investigation, carried out in co-operation with the Organised Crime and Corruption Reporting Project, found that Aughinish’s Co Limerick plant was shipping vast amounts of alumina to smelters in Russia, where it is used to make aluminium, which is then sold to a trading company, ASK, that supplies dozens of Russian arms manufacturers.This has prompted calls among EU lawmakers for alumina to be added to the bloc’s sanctions lists. Irish Government Ministers have responded that such a move would damage Europe more than Russia.During an appearance on RTÉ’s Morning Ireland, Burke was asked whether he accepted it was likely that alumina exported from Ireland to Russia was being used to make weapons to kill Ukrainian people.“I have no information to suggest [that] at this point in time,” Burke said.He said his department was carrying out an “investigation” into Aughinish Alumina, the findings of which would be shared with the European Commission, “which makes a decision”. Burke said his department was doing a “deep dive” to ensure it was not the case that Aughinish was exporting alumina that was being turned into weapons for Russia. The Minister admitted that the Government would need “boots on the ground” in Russia to know with precision where exactly Irish-made alumina was ending up.
