A recent study has demonstrated that mining restrictions can have a counterproductive effect, as they encourage miners to seek out new jurisdictions that depend on fossil fuels.
Exponential Science has recently conducted research that has investigated the intricate implications of bitcoin mining bans on global carbon emissions. The research emphasizes that mining prohibitions may not always yield favorable environmental outcomes.
The study, “The Unintended Carbon Consequences of Bitcoin Mining prohibitions,” indicates that prohibitions may induce miners to relocate their operations to alternative regions. Many of these regions utilize non-renewable energy sources, which could potentially elevate the global carbon emissions of the Bitcoin network as a whole. The primary determinant of the interaction between prohibition policies and environmental impact, as per researchers, is the source of electrical power in the destination country.
Although it is accurate that mining necessitates a significant amount of energy, this does not necessarily result in direct environmental damage or carbon emissions. Everything is contingent upon the energy source employed: an electrical infrastructure that is powered by coal will undoubtedly generate more carbon emissions than one that is powered by hydroelectric energy. Additionally, mining restrictions may have the unintended consequence of diverting the industry from renewable energy sources, which in turn leads to an increase in the global emissions produced by the network.
Geographical factors are closely associated with the impact of a prohibition on carbon emissions. For instance, Exponential Science’s model suggests that Kazakhstan’s prohibition could decrease global emissions by 7.63%. In contrast, a ban in Paraguay would result in a 4.32% increase in emissions.
A mining prohibition could result in substantial reductions in global emissions for certain countries that depend on fossil fuels, such as China, Russia, and Malaysia. In contrast, the environmental landscape may be at odds with the effects of restrictions in numerous regions of North America or Europe.
For instance, the implementation of a mining prohibition in Georgia or Kentucky, both of which are located in the United States, could result in a decrease in emissions. Nevertheless, imposition of prohibitions in states such as California, Washington, Texas, or New York may exacerbate the environmental consequences.
The investigation also investigates the case of China, which implemented a prohibition on digital asset extraction in 2021. In spite of this, certain mining operations persist clandestinely. A complete cessation of activities in the Xinjiang province, according to the model, could decrease global annual emissions by 6.9%. Nevertheless, the Sichuan region, which is dependent on hydroelectric power, would experience a 3.8% increase in emissions as a result of a prohibition.
