Car makers will soon have to include health warnings about the environmental impact of their cars, in their advertising. The new EU rule, due to be approved tomorrow, will make manufacturers devote 20 per cent of advertising space to information on their vehicles’ environmental impact. But at the same time, the same EU politicians are letting the likes of VW and Mercedes off the hook by giving them another three years to cut their products’ emissions. That, together with reported attempts, particularly by the UK, to wriggle out of tough renewables targets, are severe blows to those who thought the UK and the rest of Europe was spearheading action to tackle climate change. Road transport accounts for one fifth of the EU’s carbon emissions. This could be reduced if vehicle efficiency was improved now not in three years time, motorway speed limits were enforced and public transport was made cheaper and easier than car use. A new prime minister together with a new set of ministers always heralds new policies. But these should make up for the deficiencies of those in post before them, not underline their predecessors' unwillingness to take on the world’s most serious environmental threat.
