Help: carbon footprint of medical oxygen?
I'm supervising an inpatient oxygen presribing QIP. I'd really like to try to motivate people into good oxygen use using a sustainability framework. I am struggling to work out how to quantify the impact of oxygen waste/savings. The only thing I can find on carbon footprnts of oxygen is this: https://www.eiga.eu/publications/eiga-documents/doc-16720-methodology-to-establish-a-product-carbon-footprint/ which is methodology but doesn't really help. This talks about carbon intensity but I'm not sure of the relevance: https://www.morningstar.com/news/business-wire/20210209006263/air-liquide-outstanding-performance-from-the-group-in-2020-that-demonstrates-the-strength-of-its-business-model
I'd be really grateful for any help! Thanks. LJ
