Bash Airlines All You Want, But Flying Still Beats Driving

Okay, so this Bash Airlines All You Want, But Flying Still Beats Driving is USA-centric, but it's an intriguing possibility that there are times when flying may be better on emissions: "This one's a little complicated, but stay with me. According to Terrapass, my Jetta will spew around 850 pounds of CO2 over 1,000 miles. Airliners.net says an Airbus A320 burns 2.569 gallons per mile, so my thousand mile flight (let's call it 1,500 miles with the connection) requires 3,853 gallons of fuel. The Energy Information Administration says a gallon of jet fuel produces around 21 pounds of carbon, which means my flight is releasing 80,913 pounds of C02. That's horrible, but it's not the whole story. Divide that number by 140 -- the number of passengers packed into that Airbus -- and you arrive at 578 pounds per person.
850 pounds of CO2 driving, 577 pounds flying. Advantage: plane"
I wonder what the figures might be in the UK ...? I suspect, given the nature of the figures they could be similar, though typical car fuel consumption figures could be different, perhaps.
