It's no secret that we live in one seriously smog-filled city, but Sadiq Khan has come up with a plan to keep Londoners a bit more clued up about just how much pollution we're dealing with. From August 15, toxic air warnings will be displayed at tube stations and bus stops when pollution is due to reach dangerous levels.
Alerts will appear on bus countdown signs, electronic signs in the entrances of all 270 tube stations and 140 roadside messages on London's busiest main roads. The warnings will flag up when air pollution is forecast to be high or very high, on the day before and the day itself.
Sadiq Khan said: 'Londoners have a right to know about the quality of the air that they breathe. These new alerts will allow them to take precautions and help them plan ahead to avoid the worst instances of air pollution'. Let's hope the new system will help Londoners breathe easier.
