There are three different types of emissions that bond rating agencies (and soon the CMS Office of Climate Change) look at when rating a health system on its emissions. These are Scope 1 and 2 emissions, which come from the health system itself and the generation of electricity used by the system, and Scope 3 emissions, which come from the supply chain.
We’re discovering that emissions from the supply chain are 3-5x higher than all other emissions combined. They’re the biggest part of your health system’s carbon footprint, but they’re also the hardest to measure.
Simply put, without getting to net zero in the supply chain, there is no achieving net zero in your health system.
