Air

Half of London’s toxic air pollution is caused by road transport.  To reduce exhaust emissions by 45%, from 8 April, its Ultra Low Emission Zone (ULEZ) standards are the toughest in the world. Dirty air kills 9,000 Londoners & costs the economy £4.5bn each year.  Soon, people from the country will come to London for the fresh air
