Sadiq Khan plans to combat toxic air along London's canals

A new guide from Arup, commissioned by the Clean Air Fund, emphasizes the importance of clean air zones for cities worldwide to combat air pollution, warning that by 2050, a significant portion of the urban population will be exposed to unhealthy air. The guidance highlights successful case studies, such as Krakow's Clean Transport Zone and London's Ultra Low Emission Zone (ULEZ), noting public opposition linked to economic concerns. Meanwhile, London Mayor Sadiq Khan expressed his worries about toxic air along the city's canals during a recent phone-in, acknowledging that health risks are exacerbated by the use of outdated diesel engines on boats. Khan stated that his authority to address the issue is limited, but efforts include education and deploying air quality monitors. He promised that plans to clean up the waterways will be established within a year, paralleling previous road improvement initiatives. The growing number of boats in London, which doubled between 2010 and 2020, has further complicated the air quality challenges in the area.
