Birmingham was one of the first cities outside London to adopt a Clean Air Zone when it launched in June. The new driving law means drivers face an £8 per day fee to use some of the city centre’s most popular roads.
Mr Zaffar has previously said the Clean Air Zone would “save lives” across the city.
Speaking on the launch back in June, he said the initiative would provide “safer space for communities” and would be a “significant step” to reduce health inequalities.
Birmingham’s new Transport Plan said the Clean Air Zone was just the “first step” in addressing air quality concerns in the city.
The report added revenue from the Clean Air Zone would be reinvested in transport schemes to improve the network.
