Councillors are to meet to discuss plans to improve Bristol's air quality.
One option is to introduce 'clean air zones' which will involve bringing in charges for some drivers in the city centre.
The 'clean air zones' won't affect every driver. The aim is to focus on older cars that aren't as efficient or clean as modern vehicles.
The zones will charge these older cars a fee to drive in the city centre, and possibly wider area.
They would use vehicle registration cameras to enforce the rule.
In March this year senior Bristol City Council politicians agreed to push the city’s clean air plan forward.
The meeting today will decide the future of Bristol's air quality and how to improve it.
Councillors will also decide on the 'clean air zone' boundaries and where they should stop.
A decision is due to be made by November and if the plan goes ahead then it won't be fully operational until the end of 2019.
