## Summary

The Rail Safety Standards Board (RSSB), based in London, is currently in the Tender stage of a public procurement process for a project titled "1016654387 2025-SUS-007 Rail Infrastructure Carbon Conventions". This project falls under the research services category and aims to improve efficiency and standardisation in rail infrastructure through various objectives related to asset taxonomy and emission factors, among others. With a total estimated contract value of £150,000, submissions for this open competition are due by 6th May 2026. The contract period is set to begin on 6th July 2026 and conclude on 6th April 2027. It is managed through an open procurement method, specifically designed to be below threshold competition, allowing electronic submissions via the Delta eSourcing platform.

This tender presents significant opportunities for businesses specialising in rail infrastructure research and development, particularly those able to offer innovative solutions that align with standardisation and sustainability goals. Small to medium enterprises (SMEs) and voluntary, community, and social enterprises (VCSEs) are specifically encouraged to participate, offering a chance to contribute to reducing variability in rail assessment while fostering industry advancements. Companies with expertise in developing standardised metrics, emission factors, and lifecycle analyses would be well-suited to effectively compete for this contract, potentially establishing themselves as key players in the future of sustainable rail infrastructure projects.

## Notice

RSSB is seeking to procure a research supplier to deliver the project scope detailed in the Work Packages (WPs) detailed in the Project Scope. The Objectives of the RICCs are to: 1. Develop a GB rail specific translation of the ICMS 3 asset taxonomy that maintains full ICMS 3 compatibilities while enabling like-for-like comparison of assessments 2. Develop a proportionate, standardised set of GB-rail asset and works descriptors, together with a simplified uncertainty framework, to enable designers to consistently reuse and interpret past assessments and to clearly understand and communicate the associated levels of uncertainty 3. Establish a set of standardised GB rail component build-ups that make underlying assumptions explicit and consistent, reducing assessor variation and saving time by enabling faster, more efficient early-stage WLCAs 4. Establish a consolidated, GB rail appropriate set of default emission factors that standardises assumptions, reduces assessment variability, and delivers cost and time savings by enabling more consistent and efficient early-stage WLCAs 5. Define consistent, GB rail appropriate lifespan, replacement, and maintenance assumptions to reduce modelling variability and save time and cost by enabling more reliable, efficient early-stage WLCAs 6. Ensure the conventions are, as far as practicable, compatible with existing GB and EU standards and informed by recognised best practice both within rail and across other sectors.
