Currently, fuel price differentials between EU countries make it worthwhile for truck drivers to alter their routes to benefit from low tax rates on fuel. While this has a negative impact on the environment (in wasted truck miles), it also leads to distortions of competition between countries with different tax rates, with hauliers who have access to low taxed fuel able to gain market share at the expense of those forced to pay higher fuel taxes. The current Energy Tax Directive (2003/96/EC) lays down a series of minimum rates for excise duty on energy products. The new Commission proposal would increase the minimum rate of excise duties on commercial diesel from EUR 302 to EUR 359 per 1,000 litres in 2012 and EUR 380 per 1,000 litres in 2014, forcing lower-taxing Member States to increase their excise rates.
