Sadiq Khan vows to make London carbon-neutral by 2030 if re-elected

Mayor's pledge on air pollution to form part of vision for green new deal for London

Sadiq Khan will promise to put London on a par with Scandinavian capitals by making it a carbon-neutral city by 2030 if he is re-elected as mayor of the capital later this year.

The Labour politician's pledge to tackle air pollution forms part of his first major pitch to voters in the upcoming mayoral race, in which he will go up against Conservative, Lib Dem, Green and independent rivals.
