The Mayor of London’s plan to extend London’s Ultra-Low Emissions Zone (ULEZ) to Outer London is causing great consternation but having looked at the criteria by which vehicles will be charged it seemed to me like the objections are over stating the real impact. Especially after I discovered that our 19 year old Ford Focus will be exempt.
So I wanted to try and understand the impact these proposals would have on car owners in London. To do that I needed to be able to:
- count vehicles registered to households according to their London Borough
- categorise them according to their fuel
- group them according to the year they were registered
