Europe
In the developed countries of western Europe, the prices of transport fuels are made up of the price of the refined product, plus a substantial tax element, which can vary between roughly 2/3 and 3/4 of the total price. (in the UK nearly 70% of the price of a litre of petrol is made up of fuel duty and VAT. A doubling of the oil price would add perhaps 30% to the cost of fuel at the pump in the UK, if the duty was not changed.) These taxes are not harmonised, nor are different countries' budgets updated at the same time. As a consequence, people who live nearby will often find it worthwhile to drive over the border to fill up, despite the hassle and traffic congestion this causes. However, in general, by having a large tax fraction, governments have the benefit of some room for manoeuvre, to smooth sudden price shocks by relaxing and then slowly ramping back the fuel duties, and the population has lifestyles that are already well adapted to fuel prices that would appear very high to consumers in the USA (where the tax fraction is less than 20%). These two effects conspire to make European demand largely independent of the crude oil price, at least over short periods of a few years. The high prices also stimulate interest in hybrid cars and alternative fuels, as well as encouraging the use of public transport in cities, and are a major factor in limiting European
urban sprawl.
