The Welsh Conservatives and Plaid Cymru are among those calling for clean air zones to be introduced across Wales.
They want them in towns like Wrexham with calls for older more polluting cars to be banned in the zones.
Steve Brooks from environmental charity Sustrans Cymru has told us transport's the biggest contributor to air pollution:
'It's in urban areas where traffic is getting really congested where we basically need to start thinking about how we clean our air.'
We've asked the Welsh Government for a response.
