Taxi Guide has now been published

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 colloboration with EST, have produced a Low Emission Taxi guide as part of their 2017/18 work programme. The overarching aim of the guide is to assist taxi operator purchase decisions and stimulate the take up of low emission taxis. The guide will also serve as a useful reference document to local authorities who have a range of powers related to taxi licensing. By providing a myriad of update to date and accessible information we hope to raise awareness about the environmental, practical and economic benefits of operating low emission taxis. The guide will essentially identify how different technologies and fuels best suit different taxis operations, including both black taxis and private hire vehicles. The guide will cover technology and fuels currently on the market and those that will enter the market over the next 12 months.

LowCVP have previously produced a Low Emission Bus Guide (2016) and a Low Emission Van Guide (2015) to help operators understand the suitability of different low emission technologies and fuels for their particular fleet operations. We have undertaken research over the last three years which has identified the important role that independent, informative and assessable information has in influencing the take up of low emission vehicles. LowCVP are well placed to produce this guide given their independent status, technical expertise and collaborative approach with their multiple stakeholder members.


  1. To set out the business, environmental and operational case for low emission taxis.
  2. To provide a brief overview of the policy framework national, regional (London) and local relating to air quality, climate change and specifically to taxis. Highlight current fiscal incentives.
  3. To provide an over view of the range of low 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.
  4. To present low emission taxi operator case studies from different part of the UK.
