Due to differences in fuel mix, consumption level and price, the tax burden imposed by each scenario will vary according to country. Table 5 shows the tax revenue per unit of GDP for each country in 1995; these rates will increase by a factor of 3.3 between 1995 and 2002, as the tax rates increase, and decline as energy intensity declines thereafter. The total tax revenue for 1995 and 2030 is also shown, in constant US$1990 prices.
