ULEZ’s expansion won’t have a major impact on the London Underground, but it will on other modes of transport – notably the most common mode of public transport in Outer London – buses. Transport for London has stated that “one million extra kilometres” of buses will come to the rescue of anyone wishing to avoid the £12.50 a day charge. Last year London’s bus network travelled 473m km. So a 1m km increase is 0.21 per cent. The Mayor claiming this will mitigate ULEZ concerns for outer London given this limited scope is contemptuous.
