Plans for an EU-wide pollution-based car tax will be backed by Euro-MPs today.
The European Commission wants to scrap varying national car and road taxes in EU member states in favour of a standard taxation system centred on CO 2emissions.
MEPs agree pollution should be the standard yardstick rather than national registration taxes.
A report to be voted on in Strasbourg warns against taking tax policy out of national hands but says different car tax systems are a consumer burden
- particularly for motorists wanting to register their cars elsewhere in the EU when moving around Europe for work.
Conservative MEPs are refusing to back the new plan if a system based on CO 2emissions forces vintage and veteran cars off the road. But hundreds of other MEPs want to see a green-based car tax system applied across the 25 EU countries.
The MEPs' vote has no legal force - the scheme could only become law if approved unanimously by EU governments, and there is no majority among member states for the plan.
The report, by a European Parliament committee, says that transport accounts for 28 per cent of all CO 2emissions in the EU, and almost half of that share is caused by passenger cars.
The report endorses the idea of introducing an EU-wide "pollution element" in car taxation.
