Answer for Crossrail and CO2 Emissions

Answered By: 
Peter Hendy (Commissioner, Transport for London)

An assessment of carbon dioxide emissions was undertaken as part of the Environmental Assessment. The results are provided in the Crossrail Supplementary Environmental Statement, published in May 2005. ( supplementaryenvironmentalstatement/$FILE/wm_ses+17-05-05_pt01.pdf Pg 15 & 16).

The construction of Crossrail will result in the emission of carbon dioxide as a result of the transport of materials, the use of on-site equipment and the consumption of materials. During the operational phase, Crossrail will reduce carbon dioxide emissions through the modal shift of journeys from other forms of transport such as car use. This reduction is predicted to outweigh the emissions resulting from operational electricity consumption.

The assessment showed that there is high potential for Crossrail to have a net positive impact in terms of reducing carbon dioxide emissions, although further detailed design is required in order to quantify this impact. This includes working with contractors to develop more detailed construction plans, and further work on energy saving measures such as regenerative breaking, heating, lighting and ventilation systems.
