He had asked his distinguished guests to attend the event by public transport in order to minimize CO2 emissions.

Despite his active environmental campaigning, the former U.S. Vice President Gore has been criticised by other environmental campaigners in his career. On this occasion he was accused of 'stupidity and hypocrisy' by Marc Morano, Executive Editor of the Climate Depot website.
Now it might be true. It is also true that Greens have often been critical of Al Gore.
