The Objectives of the RICCs are to: - 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 - 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 - 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 - 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 - 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 - 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.
