Concerns raised over the impact of the CAZ on businesses as a result of plans to charge high-emission vehicles to drive across Greater Manchester have caused a review.
From 30 May, some vehicles could be charged between £7.50 and £60 daily under the current Clean Air Zone plan. The mayor, Andy Burnham, has said the government "needs to do more" to support businesses who had also been affected by the pandemic and that "We have to review the situation that we are in and go back to the government.”
Greater Manchester Combined Authority (GMCA) said it has been told to "achieve compliance with legal standards by 2024 at the latest".
Coaches, vans, buses, taxis, private-hire vehicles and lorries would be charged under the current CAZ plan but private cars are not included.
The government has provided £120m to help eligible drivers in Greater Manchester, including small businesses, the voluntary sector and HGV owners, switch to compliant vehicles.
