Why Emission Based Permits?

A commenter on a previous post asks for a rationale for the policy, so here it is.

Firstly, the environmental case. By linking CPZ payments to emssions levels, we are sending a signal to people to think about their emissions. Hopefully, this will help to reduce pollution. When we were discussing this pledge before the election, I think we were thinking mainly of carbon emissions, but the public consultation has drawn up a lot of concern on health grounds as well. High carbon emissions are a good proxy for other kinds of harmful emissions, like particulates, so the policy would be similar wherever you lay the emphasis, but the original intention was certainly about climate change.

The second aspect is why this level of charges? The level of charges was based on comparison with neighbouring authorities. Since, the vast majority of Brent's CPZs are in the east and south of the Borough, it made sense to compare with the authorities immediately neighbouring them. In doing so it is important to emphasise that most Brent drivers fall into bands 3, 4 and 5 (between £75 and £125 per annum). Camden currently charges between £84 and £164. Westminster has a few small cars paying £85, but most pay £125. Hammersmith and Fulham and Kensington & Chelsea have a £99 flat rate, so the figures for the m,ost comparable authorities are fairly similar to us (although we don't know how long they will stay at that level).
