Bristol is set to become the UK's first city to ban diesel cars from entering parts of the city centre in a bid to cut air pollution.
Bristol City Council has agreed to ban privately owned diesel cars from a central zone in the daytime. Commercial vehicles will pay to enter the area.
The city has long suffered from poor air quality, particularly from high levels of nitrogen dioxide (NO2).
The scheme, which needs government approval, is due to start in 2021.
