Who are RSSB?
Established in April 2003 as a result of the public inquiry into the Ladbroke Grove accident.
We support our members from across the industry in continuously improving health, safety and sustainability. Our members include:
The Rail Safety and Standards Board (RSSB) are an expert body, encompassing the whole rail industry

What is the Rail Carbon Tool?
The tool enables organisations to:
• Calculate and analyse the carbon footprint of UK rail projects
• Identify alternative low carbon materials
• Select low carbon solutions
• Meet contractual requirements
Online platform which can be freely used by those in the GB rail sector to measure embodied carbon.

Why is this important for rail?
• Particularly important for rail due to the large number of high carbon infrastructure projects.
• All train operators have franchise requirements to report their embodied carbon for infrastructure projects over £1 million.
Reducing embodied carbon is important for reducing resource use and associated costs
• Network Rail have mandated that from December infrastructure projects with over £1 million spend must use the RSSB Rail Carbon Tool.

Midland Metro ExpansionMoved from traditional steel rebar reinforced concrete to plastic fibre reinforced concrete, saving 15% embodied carbon per m3 of concrete
Polymer concrete boxes were specified as an alternative material, reducing embodied carbon of the drainage boxes by 50%
Expansion joints changed from stainless steel to plain steel dowel, reducing embodied carbon of the joint reinforcement by 50%.

Reading Elevated Railway
Design changes reduced the capital carbon footprint of the project by over 26,975 tonnes CO2e, 42.4% of the pre-VE carbon assessment and saving over £9.5 million, representing 12% of the original cost of the project.

Great Western Railway Modernisation
Implemented two design changes which reduced the embodied carbon of electrification works per mile by 20 tCO2e on the project:
• Reduction in the thickness of steel used in the OLE masts from 16mm to 12mm,
• Optimisation of foundation depths to reduce the length of piles required by up to 10%.
