Low Emission Taxi Guide

Taxis in a row

Project Brief

Taxis (black taxis and private hire vehicles) can be an important source of road transport air pollution and CO2 emissions in cities. With the increasing pressure of improving local air quality and the establishment of Clean Air Zones, and the London Ultra Low Emission Zone, taxi operators will need to evaluate the suitability of their current vehicle(s) with regards to achieving mandatory vehicle emission standards. There are a range of fuel and technology options a taxi operator can choose in terms of shifting to a cleaner fleet, taking into account reducing NOx and PM emissions in conjunction with GHG emissions.

LowCVP, in collaboration with EST, will produce a Low Emission Taxi guide for local authorities. The guide will identify how five different low emission technologies and fuels best suit different taxis operations, including both black taxis and private hire vehicles. In addition the guide will provide a range of national and local policies and measures aimed at accelerate the take up of low emission taxis. Guidance on deploying EV infrastructure will be provided and advice on partnership working.


  • To set out the business, environmental and operational case for low emission taxis.
  • To provide a brief overview of the policy framework national, regional and local relating to air quality, climate change and specifically to taxis. Highlight current fiscal incentives.
  • To provide an overview of the range of low/ultra emission technologies and fuels suitable for taxis and match these to different types of operators and journey patterns. Demonstrate total cost of ownership and environmental performance. Provide guidance on charging and refueling infrastructure.
  • To present low emission taxi operator and local authority case studies from different part of the UK.

The acceptance of so many significant changes in technology have mainly been driven and brought about by the dedication of the LowCVP.
