ai Monthly network energy consumption (a), carbon emission per GDP (b), carbon emission flows (c), network hash rate (d), miner cumulative profits (e), block hash difficulty (f), energy consumption cost (g), miner profit rate (h), and carbon emission cost (i) under each intended policy are simulated and calculated by BBCE framework. Based on the regressed parameters of the BBCE model, the whole sample timesteps of network carbon emission assessment cover the period from January 2014 to January 2030.
