It seems like most of the energy associated with espresso would not come from the brewing step, but rather from the cultivation, processing, and transportation of the beans. Similarly, the brewing energy is likely 100% electrified, and could be supplied by carbon neutral sources, while the energy from earlier in the process is more likely to be from fossil fuels.
