The Mayor of London, Sadiq Khan, has commissioned a report to evaluate the impact on air pollution of the twelve Low Emission Bus Zones that are now all delivered and fully operational.
Pollution from vehicles including buses are responsible for over half the harmful emissions Londoners breathe. Low Emission Bus Zones are one tool to address this. Stops within the zone are only serviced by buses with top-of-the-range engines and exhaust systems that meet or exceed the highest Euro VI emissions standards. The zones have been prioritised in the worst air quality hotspots outside central London where buses contribute significantly to road transport emissions.
The report shows that the Low Emission Bus Zones have led to significant reductions in pollution levels. The first two Low Emission Bus Zones at Putney High Street and Brixton in particular have had a major impact, with Putney High Street exceeding legal limits for just one hour so far in 2019 compared to 289 over the same period in 2016, a reduction of over 99 per cent. The average reduction in annual average nitrogen dioxide at the nine Low Emission Bus Zones where monitoring is available is 28 per cent compared to 2016.
