More carbon-polluting new cars are being sold in Oxfordshire than anywhere else in the country, according to the results of a survey.
The Society of Motor Manufacturers and Traders survey suggests the average CO2 emission of a car bought in Oxfordshire was 168 grams per kilometre.
The figure was 17g/km higher than second-placed Grampian and more than 30g/km above the EU target.
The county with the lowest emissions was Cornwall at 138.26g/km.
Nikki Rooke from SMMT said that nationally new car emissions were dropping.
She said: "What's important is that overall and particularly over the last year we've seen average new car CO2 emissions drop by 5%."
Motor journalist and former Top Gear presenter Chris Goffey said he was not surprised by Oxfordshire's figures.
"A lot of people are in the agricultural business. They tow trailers, they tow equipment, some of us have livestock and we tow trailers with livestock in," he said.
"You can't do that with a one-litre hatchback."
