Not just Southampton.

Birmingham, Leeds, Nottingham, Derby and Southampton have been ordered by the Government to impose charges on “clean air zones” in an attempt to cut pollution which experts say causes hundreds of excess deaths a year in Birmingham alone.
Charging is to be introduced by 2020 for high-pollution taxis, buses, coaches, lorries and light goods vehicles such as commercial vans.

The first congestion charge in the UK was a much smaller £2 million scheme which has been running in Durham since 2002, however the London scheme was the first large-scale implementation. Following implementation the Institute for Public Policy Research, a left-wing think tank, to call for similar schemes to be rolled out across the country. However, in November 2003, Secretary of State for Transport Alistair Darling said that despite apparent initial interest from many city councils, including those of Leeds, Cardiff, Manchester, Birmingham and Bristol, no city apart from Edinburgh had yet approached the Government for assistance in introducing a charge.
