The European Central Bank (ECB) recently delved into examining the environmental effects associated with the use of banknotes, identifying 16 distinct environmental impact categories. Notably, like cryptocurrencies, energy efficiency emerges as a significant concern in this assessment.
Banknotes continue to be the prevalent mode of payment in the euro area's point-of-sale transactions. The life cycle of cash involves intricate physical infrastructure for manufacturing, distribution, and eventual disposal. The largest contributor to the environmental footprint of banknotes is the energy consumed by ATMs, constituting 37%, followed closely by transportation at 35%. Other factors contributing to this footprint include processing, papermaking, certification, and various ancillary procedures. The ECB initiated measures back in 2004 to diminish the environmental impact of banknotes. According to the ECB's report, despite a considerable rise in the number of ATMs, energy consumption at these terminals declined by 35% from 2004 to 2019. Further efforts are underway to explore the potential impact of decreased traffic.
Utilizing the European Commission's Product Environmental Footprint (PEF) methodology, the study revealed that an average euro area citizen contributes around 101 micropoints annually through cash usage, which is akin to driving approximately 8 kilometers (4.6 miles) in a car. The total average impact for EU citizens collectively amounts to just over 1 million micropoints, equivalent to circling the Earth twice in a car. These estimations are based on data from 2019.
In comparison to Bitcoin mining, whose environmental impact has been calculated by researchers using a metaphor involving millions of swimming pools filled with water, the statistics linked to cash usage appear more favorable. Nonetheless, cryptocurrency mining is progressively advancing in efficiency, offering potential avenues to alleviate its environmental footprint. Moreover, crypto miners can leverage unique advantages by pursuing certain strategies. Mining facilities can be strategically situated at fossil fuel production sites to utilize by-products of production. Some crypto miners have been installed in landfills to harness methane emissions, contributing to stabilizing the energy network.
