Transition to electric Hackney Carriages

2020 brings new emission standards for Hackney Carriage Vehicles which have been developed in consultation with City of Oxford Licensed Taxi Association (COLTA) and with feedback from taxi drivers and owners. 

It is a phased approach to zero-emission capable vehicles between 2020 and 2025, with drivers only able to get a licence in 2025 if they have a zero-emission cab.

  • From 1 January 2020: Hackney carriage taxi drivers are required to have taxis of at least Euro 4 standard to renew their licence; and Euro 4, Euro 6 or zero-emission capable to receive a new licence. The standards are based on the study of real world emissions by taxis which show that EURO 5 models perform worse than EURO 4 and EURO 3 models, and are comparable to EURO 2 models.
  • From 1 January 2022: Hackney carriage taxi drivers will be required to have at least Euro 4 standard to renew their licence, and zero-emission capable vehicles to receive a new licence.
  • From 1 January 2025: Hackney carriage taxi drivers will be required to have zero-emission capable vehicles to renew their licence or receive a new licence.
