Fig. 2: Estimated annualized scenario simulation results.

From: Policy assessments for the carbon emission flows and sustainability of Bitcoin blockchain operation in China

Fig. 2

Estimated annualized energy consumption (a) and carbon emission flows (b) of Bitcoin operation in China are generated through monthly simulation results of BBCE modeling from 2021 to 2029. The blue, red, yellow, and green bars in a and b indicate the annual energy consumption and carbon emission flows of Chinese Bitcoin industry in benchmark, site regulation, market access, and carbon tax scenario, respectively. Each data is presented as mean values ± SEM based on 95% confidence intervals calculated by two-tailed t-tests (\(p \;< \;0.05\)). n = 204 emission observations.
