A recent study by the World Bank claims that first class seats have nine-times the carbon footprint of economy seats. The report also claims that a business class seat has three times the carbon footprint of an economy class seat.
The study says that as the premium class seats are bigger, there are fewer such seats on the plane and a plane with fewer seats uses more fuel per person. The lower occupancy rates of the premium seats also lead to fewer overall passengers on the plane.
World Bank staff at its Washington headquarters traveled more than 447 million miles in 2009 with almost 80 percent of the trips in premium classes.
The report recommends that the World Bank re-evaluate its travel policies in light of the higher cost to the planet extracted by premium-class travel.
