Crawley Borough Council has urged people to give feedback on its action plan to combat poor air quality in two areas of the town.
Crawley Avenue and the Hazelwick roundabout have been found to have higher than average levels of nitrogen dioxide, meaning the council must declare them to be Air Quality Management Areas (AQMA).
Before drawing up an action plan to tackle the issue, the council wants to know if residents, businesses and town employees think the areas suggested as AQMAs are reasonable or whether people feel the areas should be larger or smaller.
A spokesman for the council said it would then draw up an action plan to reduce the pollution, which is normally caused by road traffic and other fossil fuel combustion processes.
Cllr Colin Lloyd, Cabinet member for Environment, said: “Before we formally declare the area and draw up an action plan we want to hear from local people and also those who spend a good deal of their time here.
“We want to know if people think the area we’ve outlined is properly representative of the issue, and if not, why not?
“It’s important we make the right decisions for people and the only way to do that is to listen to those affected.
“I’d urged anyone who thinks they may be affected to get in touch.”
Earlier this week, the government turned down calls to impose a higher tax on diesel vehicles.
The call was made in a report on air quality from the House of Commons Environmental Audit Committee in December.
While turning it down a government response stated there were “no plans to make significant changes to the structure of vehicle excise duty”.
Committee chair Joan Walley MP accused the government of failing to face up to the problem and “passing the buck”.
