To enable them to grab more taxesFrom reading the documentation, of both Manchester and other places, the extents of the zones are a matter of agreement between the councils and government.
On the face of it the extent of the Manchester CAZ seems large but the reasons (high levels of pollution on roads such as the A57) are given in the documentation. The A57 is a good example. As a trunk toad (so managed by National Highways) it would not normally be included in a CAZ but the government made an exeption because of pollution levels.
