So in the longer term we're still left with the question, how much of the total emissions (including supply chain) of Bosch is due to Bosch's use of electricity? If somebody makes a battery final assembly plant in Iceland, and run it on geothermal energy only, but buy battery cells manufactured in China with energy from a brown coal powerplant, it's not so interesting that the 1% of emissions from final assembly was removed.
