Lambeth Council partnered with air quality specialists Cambridge Environmental Research Consultants to carry out air quality modelling across the LTN. Additional analysis was also completed at 28 ‘sensitive receptor’ locations within or on the boundary roads of the LTNs. These are locations with lots of people that that are particularly sensitive to the negative impacts of bad air quality (children, older people, people who are unwell) and includes schools, hospitals or doctors’ surgeries. The following high-level findings were noted.

• There has been some increase in emissions on boundary roads where traffic flows have increased
• There were no significant impacts on NO2, PM2.5 or PM10 at any sensitive receptor site - including those on the boundary of the LTNs.
• A moderate benefit was modelled at Trinity Academy on Brixton Road, a slight negative impact was recorded at Magnolia Court and Leigham Lodge on Leigham Court Road.
• There has been a negligible impact at all sensitive receptor sites on the South Circular (A205)
• No locations where air quality breached legal limits for the first time following the introduction the Streatham Hill and Tulse Hill LTNs.
