 Yet again, it doesn’t count if you’re a celebrity:

Musician Will.I.Am has been criticised for arriving at a climate change debate in a private helicopter, producing the same amount of CO2 most people do in a month …

He even tweeted pictures of the so-called “hip.hop.copter” for fans to admire, after landing at the Oxford’s University Parks.

From there, the singer used a pedal cycle to travel the remaining few hundred yards to the Radcliffe Observatory Weather Centre.

Nice touch.
