An action plan is to be developed to tackle a high level of pollution caused by traffic fumes in a Sussex village.
Horsham District Council said an Air Quality Management Area had been formally declared in Storrington.
The council said an action plan would now be formed to bring long-term health benefits to people in the village.
The high pollution levels are due to a large number of vehicles and the stop-start nature of driving conditions at peak times, the council said.
Consultation was held over the move to make Storrington an Air Quality Management Area, after it was found that nitrogen dioxide levels exceeded national air quality standards in parts of the village.
The council said it had more than 90 responses largely supporting the council's action.
The Air Quality Management Area covers West Street, the High Street and part of School Hill and Manleys Hill.
Horsham council said it was working with West Sussex County Council, residents and local representatives to improve the air quality, and establish the action plan in 12 to 18 months.
