Where to focus efforts with limited resources? Manufacturing Sometimes hard to get data Conflicting numbers Can we influence manufacturers to change sources? Operation Increase efficiency (but beware Jevons!) How to baseline against greening grid? Disposal Don t neglect it! Means repair/replacement not just end of life
Notes from Hywel LCA principles used at different laboratories Policy on 'science washing' - okay or not? Common standards and baselines, e.g. which sustainability and environmental standards Database on CO2 intensity of components - consideration of country-specific factors (e.g carbon intensity) Principles of infrastructure lifespans - construction vs operation trade-off Need to explore decommissioning factors, e.g. energy/CO2 cost, recycling methodologies, separability of components Develop a 'factsheet' on CO2 and energy usage Identification of key technologies - e.g. DC/DC, PM systems etc. Identify material types where common grades can be specified, e.g. aluminium grades Explore impact of radiation activation on component material choice and its disposal Cost of computing and data infrastructure
