Study shows bitcoin mining is causing huge amounts of CO2 emissions

Signal of change / Study shows bitcoin mining is causing huge amounts of CO2 emissions

By Areeba Hasan / 31 Jul 2019

According to a new study by Researchers from the Technical University of Munich (TUM) in Germany, the production and use of Bitcoin is causing annual carbon emissions of up to 22 megatons, which is “comparable to the total emissions of cities such as Hamburg, Vienna or Las Vegas”. Despite being a virtual currency, Bitcoin consumption is responsible for huge amounts of energy consumption.

For a successful Bitcoin transfer, a user has to solve a mathematical puzzle in the global Bitcoin network. The computing capacity used in this process, known as Bitcoin mining, has increased to unprecedented amounts in recent years, quadrupling in the last year alone. New sets of transactions are added to Bitcoin’s blockchain roughly every 10 minutes by ‘miners’. This stark rise has had severe repurcussions in terms of environmental damage and according to the study it “raises the question of whether the cryptocurrency is imposing an additional burden on the climate”.

So what?

Although it is common knowledge that additional factors work towards climate change, research conductor Christian Stoll said, "the carbon footprint is big enough to make it worth discussing the possibility of regulating cryptocurrency mining in regions where power generation is especially carbon-intensive.” Bitcoin mining will continue in even greater numbers, given the success of bitcoins as a thriving tool for investment, but this success comes at a time when the climate is already suffering the consequences of environmental damage done over the years. While the need to reduce emissions in traditionally high carbon industries like transportation, mining, agriculture, etc. have become increasingly visible with time, it is equally important to address the problems in industries like bitcoin mining where the possible danger to the environment is not as apparent.




What might the implications of this be? What related signals of change have you seen?
