Questions to the Mayor of London – answered on 18th May 2022.
What lower emission diesel alternatives will be used by the construction vehicles building the Silvertown Tunnel?
As part of my review of the scheme, I ensured TfL committed that all construction vehicles used on the Silvertown Tunnel will meet the latest emission standards. This is reflected in the contract between TfL and their deliver partner, Riverlinx. This means all vehicles working on the scheme meet Euro 6 standards and all non-road mobile machinery (NRMM) meet NRMM Low Emission Zone (LEZ) standards, which is the same as for the Ultra Low Emission Zone. There are currently 82 items of NRMM on site, all of which are NRMM LEZ compliant, with 38 items of machinery surpassing these standards. Routine checks are carried out to ensure ongoing compliance. The use of hybrid (diesel-electric) construction equipment has also been trialed on the site.
Diesel alternatives such as Hydrogenated Vegetable Oil (HVO) are not currently being used on the site, due to their prohibitive cost and poor suitability for certain pieces of machinery. I have asked Transport for London (TfL), with their contractor, Riverlinx, to ensure all practicable steps are taken to reduce the impacts of the Silvertown Tunnel construction.
