About 15 years ago, travelling along an eight-lane highway in Alabama surrounded by SUVs and trucks, I thought: we aren’t going to stop climate change. At least back then the problem was mostly an American one. Now huge cars have gone global. SUVs last year accounted for a record 46 per cent of the world’s car sales, according to the International Energy Agency (IEA). If we’re serious about keeping the planet liveable, we have to regulate and tax huge cars out of existence.
Let’s not turn this issue into anything so boring as a culture war. If you feel an automated rant coming on about metropolitan elites persecuting ordinary folk, remember that huge cars are mostly driven by the rich. In the UK, for instance, the average SUV costs more than the median full-time pre-tax salary of about £33,000 — leaving aside petrol. Generally, it’s the rich who emit most CO₂. Getting rid of huge cars is about reducing emissions first and road accidents second.
SUVs evolved from the second world war jeep, but their worldwide numbers have jumped nearly sevenfold since 2010, to about 330 million. (This includes “crossovers”, car-like platforms on to which larger, SUV bodies are grafted.) Given that SUVs consume one-fifth more oil than medium-sized cars, they now emit about three times more carbon than the UK, per the IEA, which also says that they “have helped keep transport emissions rising “at an annual average rate of nearly 1.7 per cent from 1990 to 2021, faster than any other end-use sector”. Passenger vehicles already account for about 9 per cent of all global emissions. And every day, more people on Earth can afford to buy a car.
