Standardisation is proving a struggle The European Commission claimed that the proposals in its 2012 Green Paper would help to standardise the EU's system of VAT and recover lost revenue. However, the document has failed to deliver, a conference of indirect tax specialists was told last month. The Green Paper contained a number of proposals, which aimed to make the VAT system in Europe more efficient, simple and robust. However, Mark Delaney, of Baker & McKenzie, who has attended key discussions between member states and the Commission, told a conference his firm hosted in Milan that little has come from the Green Paper, as of yet.
