Since its release back in 1986, Chris Rea's 'Driving Home for Christmas' has been one of the most popular Christmas hits in the UK.
But a new study suggests that if Rea is feeling eco-friendly this Christmas, he might have to release a new version of the track.
Scientists have calculated that Rea's journey from Abbey Road music studios to his home in Middlesbrough in his wife's Austin Mini would have produced 44kg of carbon dioxide (CO2).
However, the team from the University of Sheffield say that he could have slashed his carbon footprint by a whopping 88 per cent if he'd taken the train instead.
