Madonna has sparked fury after travelling just 120 miles in her private jet.
The 57-year-old star - who is a Greenpeace activist - travelled to London from Birmingham after her concert in her own jet, despite the fact driving would have only taken approximately 45 minutes longer.
The 'Hung Up' singer - whose 2007 song 'Hey You' highlighted global warming - opted to take her 12 seater private jet, resulting in an estimated travel time of one hour and 25 minutes when including travel to and from the airports.
However, driving the 126 miles from Birmingham to London would have only taken approximately two hours and 11 minutes.
Friends of the Earth's David Powell said: "We want celebrities to turn their back on private planes and choose more sustainable forms of travel."
It's estimated Madonna's journey would have contributed 2.907 tonnes of carbon emissions while a stretch limo would have produced just 0.081.
Staff at Birmingham airport were reportedly "stunned" to see Madonna board the plane for the £10,000 25-minute flight last week, according to The Sun newspaper.
