With the advancement of decentralized renewable energy production and increased competition, the energy industry is putting high hopes on innovations which hold the potential to reduce the cost in the industry. One of the innovations with such a potential is considered to be the blockchain technology. The most prominent and first ever blockchain application is the cryptocurrency Bitcoin. However, last year, media outlets such as Forbes or the Washington Post warned about Bitcoin's climate footprint following a study published in Nature Climate Change.
The media's attention and subsequent warnings were certainly appropriate as the authors of the study, Mora et al., came to the conclusion that Bitcoin emissions alone could render all efforts of the Paris agreement ineffective as Bitcoin emissions alone could push global warming over the 2° C threshold within the next two decades. Mora et al. identified the decentralized proof of work mechanism of Bitcoin's blockchain as the reason for the cryptocurrency's emission. This would certainly be a rather gloomy outlook for the energy industry with its high hopes for the blockchain technology should the analyses of the study be accurate.
In this seminar, the question will be elaborated on how dangerous Bitcoin and the blockchain technology is for the global climate. For this, the mechanisms behind Bitcoin and blockchain technologies will be presented. Furthermore, the seminar will emphasize on methods to estimate current and future energy consumption and greenhouse gas emissions of Bitcoin mining. Eventually, the hypothesis that Bitcoin emissions alone can push global warming over 2°C will be re-evaluated.

Summary :
Prof.-Dr.-ing. Aaron Praktiknjo, Assistant Professor for Energy Resources and Innovation Economics at the E.ON Energy Research Center at RWTH Aachen University in Germany and visiting researcher at the Energy Studies Institute, presented on whether or not Bitcoin and the blockchain technology are dangerous for the global climate. Through a dissection of the mechanisms behind Bitcoin and blockchain technologies and methods to estimate current and future energy consumption and greenhouse gas emissions of Bitcoin mining, Prof. Praktiknjo presented a reassessment of the claim of bitcoin emissions alone pushing global warming over 2°C within the next two decades. The seminar was organised on 4 December 2019 and was chaired by Dr. Victor Nian, Senior Research Fellow of Energy Studies Institute, National University of Singapore.
