They're an increasingly common sight on Irish roads, but there's a call for SUV's to be phased out.
A professor of Environmental Engineering says the popularity of sports utility vehicles means even increasing sales of electric vehicles 'have not made a dent' in transport emissions.
Trinity College Professor Brian Caulfield says SUV's emit 20% more pollutants than regular cars, and even fully electric models aren't a solution because of the emissions intensive way they are produced.
He's told the Irish Examiner sales of SUV's should be phased out, or the vehicles should be subject to extra taxes and parking restrictions.
"We should be looking at SUVs because they are massively contributing to our emissions problem. For every five SUVs sold, you knock out the benefit of an EV. "
