Let's say you have a facility where chips/semiconductors/electronic components are produced. Supplying this facility with green electricity only is pretty easy.

Let's say you have a facility where chips/semiconductors/electronic components are produced. Supplying this facility with green electricity only is pretty easy. Sign contract with energy company, done. All the raw material inputs needed to produce the components, that's where it gets interesting. I kind of doubt you'll find a copper (or whatever) mine where green electricity powered dump trucks drive around (which .. in turn would need to have been produced sustainably, otherwise they add CO2 to the BOM). And good luck trying to first build the factories for the production of components from exclusively decarbonized materials. Steel? Concrete? Plastics?
