This source[1] puts bitcoin-related electricity consumption at around 165 TWh/year, which is larger than the annual consumption of all but the 23 largest countries[2]. Much of that electricity is not going to be from renewables, hydro, or nuclear, so generating CO2 and other GHG. However, I suspect what makes it be perceived as particularly environmentally unfriendly is that there is no inherent societal value in the effort.
