When will a Clean Air Zone begin?

We haven’t yet decided if, or what, vehicles will be charged. This will be determined in the technical work in 2018. If a charging CAZ is introduced, implementation will begin in 2019 and the measures in the Plan should be in place in 2020, but this will be dependent on the scheme selected and the multitude of factors influencing difficulty of implementation. We believe that the soonest we can achieve compliance is 2021 but if compliance is possible sooner we will try and achieve this.
