Our recent work on the carbon footprint of industrial electric motors (specifically for NEMA premium motors) shows that the production emissions are well within 1% of the total life-cycle GHG emissions. The use phase is responsible for most of the emissions. Compare this to systems like computers, where significantly more knowledge is embedded in the product (which makes the production more intricate and complex) and the production share of the carbon footprint is much higher (for example, 44% for the 20-inch iMac). But the sheer bulk of a large industrial motor makes its absolute carbon footprint much higher than that of a desktop computer.

Can you enumerate which of the greenhouse gases were measured? Can you break out the electric motor emissions data by each greenhouse gas? Also, can you recommend where to find specific GHG emissions data for PSC electric motors? ECM motors?
Thanks
