New London Mayor, Sadiq Khan is continuing his city's policy of making public transport cleaner.

With already more than 70 zero emission buses, London is preparing for another major shift with two goals:

  • No more new pure diesel double-deckers added to bus fleet from 2018
  • All new single-deckers for central London to be zero-emission

In this case, zero emission means all-electric or hydrogen fuel cells.

As a point of interest, the world’s first double-decker hydrogen bus was recently unveiled by Wrightbus (and is pictured below).

"The new hydrogen double-decker is at the forefront of green technology and will be trialled on London’s roads next year.

It is made by leading UK bus manufacturer Wrightbus and forms part of the Mayor’s plan to transform the capital’s bus fleet by phasing out the oldest and most polluting diesel buses, and making the entire fleet ultra-low or zero emission."

The Mayor of London, Sadiq Khan, said of the changes:

“I want London to become a world leader in hydrogen and electric bus technology. I’m implementing hard-hitting measures to clean-up London’s toxic air and it’s great that more cities are getting on board to phase out the procurement of pure diesel buses which sends a clear signal that only the cleanest technologies are wanted in our cities.

“Transforming London’s bus fleet by accelerating the introduction of zero-emission buses is important and I plan to work with bus manufacturers, other cities, the European Commission and the C40 Climate Change Leadership Group of Cities to move this agenda forward.”

Mike Brown MVO, London’s Transport Commissioner added:

“We’re determined to make our public transport system one of the cleanest in the world and phasing out diesel buses lies at the heart of this. Zero emission buses are the future, and my staff are working hard with manufacturers and bus companies to make them a reality in the Capital as quickly as possible.”
