The original prediction for Tideway’s total carbon footprint was 840,000 tCO2e*.

Thanks to our carbon-cutting measures, the final project carbon footprint is expected to be 770,000tCO2e. That’s an eight per cent reduction in carbon emissions.

The Tideway Tunnel has a primary and secondary lining, which requires significant quantities of carbon intensive materials, primarily concrete and steel fibres. One of the ways Tideway’s Main Works Contractors delivered material efficiencies was by reducing the thickness of the secondary lining. This led to a carbon reduction of 11,800 tCO2e.
