Manchester should consider introducing a congestion zone to reduce the "invisible killer" of air pollution, according to a new report.A study by the Institute for Public Policy Research (IPPR) says the region has a similar air pollution problem to London, caused mostly by vehicle emissions, but lacks the powers and strategies to tackle it.

The IPPR is calling on the Mayor of Greater Manchester Andy Burnham to consider a London-style congestion zone charge to help keep the air clean.

The human cost of this air pollution crisis to Greater Manchester cannot be overstated.
