UK Defends Boris Johnson's Plan To Jet Out Of COP26

Aviation -- especially the private kind -- is a bete noir of the environmental lobby as it emits vastly more carbon per passenger than other forms of transport.

Prime Minister Boris Johnson will fly back to London from Glasgow rather than taking the train, Downing Street said Monday hours after he chided world leaders for not doing more on climate change.

Aviation -- especially the private kind -- is a bete noire of the environmental lobby as it emits vastly more carbon per passenger than other forms of transport.

Hundreds of campaigners attending the COP26 conference in Scotland's biggest city have come up from London by train, although the main line to Glasgow was hit by lengthy storm-related delays Sunday.

Johnson flew in to COP26 late Sunday from Rome, where he was attending a weekend G20 summit, aboard a chartered Airbus plane painted in a patriotic UK livery.
