Abstract :Cryptocurrencies have become as an innovative way to conduct financial transactions online. However, recent concerns about its environmental impacts have emerged. Cryptocurrencies significantly increase the energy system's load, which raises carbon emissions that contribute to global warming. The production and transmission of electricity for cryptocurrency mining has several negative environmental effects, regardless of the energy source. The impact of Bitcoin mining on climate change was investigated in this study. Therefore, it focuses on the correlation between the worldwide carbon emission index and Bitcoin mining's energy consumption. The objective is to forecast future carbon emissions from Bitcoin mining using artificial neural networks. Using an Artificial Neural Network (ANN), CO2 emissions are estimated for the following periods based on the values such as Bitcoin market price, Bitcoin USD exchange trade volume, Bitcoin hash rate, Bitcoin mining's energy consumption of previous periods. Keywords : Cryptocurrencies, Bitcoin, Climate Change, CO2 Emission, Artificial Neural Networks
