The average car sold in the UK currently produces 13 percent less CO2 than 10 years ago. This is calculated from the total sales figures, which also reveal that almost 40 percent of the new car market produces under 140 g/km CO2, compared to less than four percent in 1997. In general figures, cars emit 4.8 percent less CO2 compared to 1997; 68.7 million tons vs 72.2.
Although not as many diesels were sold in the UK as in other European countries (France has 60 percent diesel penetration, Spain 70 percent, for instance), diesels still made up 40.2 percent of the UK marker, compared to 26.5 percent in 1997. One reason is different taxes in the UK compared to other EU countries. The SMMT's report also explains that tax revenue from car drivers is up from £33.8 in 1997 to £45.1 billion. Not bad.
