Blockchains nachhaltig gestalten

Vorschlag von nachhaltigkeitsorientierten Entscheidungskriterien und eines Verfahrenskonzepts für die Umsetzung staatlich geförderter oder initiierter Projekte im Bereich Blockchain

Blockchains and other Distributed Ledger Technologies (DLT) promise to contribute to reorganizing the processes of the digital world of the 21st century, to boost efficiency of transactions while opening-up yet unseen options of digital interactions in our economy, society and public administrations. It is time to leverage these opportunities. At the same time, however, blockchains as any other digital solution are contributing to environmental impacts such as energy consumption, resource depletion and greenhouse gas emissions. At present the energy demand of the largest blockchain network Bitcoin is estimated to reach some 130 TWh/year, equaling the total electricity consumption of entire countries such as Argentina. Blockchains and other DLT, hence, need to be designed and operated in an ecologically benign way. This study investigates suitable indicators and methods to evaluate the environmental impact of blockchains and sketches a pragmatic proposal for applying such criteria in blockchain project evaluation.
