Measures such as the Emission Surcharge demonstrate your ambition to get the most polluting vehicles off London's roads as soon as possible. Converting old diesel cabs to LPG could also help to deliver significant emissions. Will the Mayor consider a loan scheme or fund to help cabbies convert the most polluting vehicles to LPG, which would help to clean up London's air in the short term and could pay itself back through significant fuel cost savings?

Transport for London will introduce new licensing requirements from 1 January 2018 to reduce emissions from the taxi fleet by phasing out diesel taxis and increasing the number of zero emission capable (ZEC) vehicles in London. This is a positive step towards achieving my ambition of cleaning London's polluted air, and I am pleased that our world-renowned taxis will be at the forefront of my initiative, pioneering cutting edge, green technology in the Capital.


Whilst widespread LPG conversion can help to remove diesel, it remains a bridging fuel and its air quality and CO2 benefits are far below those of ZEC technology. I believe it is important to offer a clear direction to the trade and this means focussing our efforts on initiatives that prioritise and accelerate ZEC taxis and that remove older vehicles from the fleet. Therefore, I currently do not intend to divert investment towards LPG retrofit.
