With regard to the environmental impacts of the Silvertown Tunnel, TfL has commissioned Hyder Consulting to carry out extensive air quality and other environmental assessments during 2014. In order to collect a robust baseline for the air quality work, data is being collected from the London Air Quality Network, the London Atmospheric Emissions Inventory and air quality model. Hyder has also contacted organisations such as Defra and 22 local authorities for data.

Supplementary to these sources, diffusion tubes have been installed across 10 boroughs to enable TfL to better characterise existing air quality in east London. All of the data will feed into describing the existing baseline NO2 concentrations and will also be used to validate the air quality modelling undertaken as part of the air quality assessment. 

In addition to working with the local authorities to collect baseline data, an Environmental Impact Assessment Scoping Report has been prepared which outlines the methodology for the environmental work (including air quality). A Scoping Opinion has been received from the Planning Inspectorate and discussions on the air quality assessment were held with the host boroughs; London Borough of Newham and Royal Borough of Greenwich, and comments were received from London Borough of Tower Hamlets.

An Introductory Environmental Assessment Report has been prepared for the current public consultation; this has been circulated to a number of London boroughs, specifically the Environmental Health Officers in the host boroughs. TfL is hoping to receive comprehensive comments from the boroughs, particularly on the air quality assessment work.
