Ernst & Young Baltic, member of the EY network, used the emission assumptions of highly polluting EURO II trucks (manufactured before 2001) to falsely increase the socio-economic benefits of the new railway for the period 2026–2055 by 3 billion euros in the Rail Baltica Cost-Benefit Analysis. Total mistakes amount to more than 4 billion euros that constitute 20% of the total socio-economic benefits of the Rail Baltica. Correction of the mistakes makes the project unfeasible. EY has refused to provide any comments to the media regarding the public accusations.
