Die Fusion steht bevor, doch sind wir auf die Probleme vorbereitet, die sie mit sich bringen könnte? – Die Bilanzierung der Treibhausgasemissionen und des Energiebedarfs wirft auch Fragen der Gerechtigkeit und Gleichheit auf.

From the article

>Fusion energy may also placate energy security concerns because some of its key resources are abundant. For example, the deuterium fuel used in some fusion processes can be [readily derived from seawater](https://www.iaea.org/newscenter/news/what-is-deuterium). This would reduce reliance on imports and insulate nations against global market shocks.

>But these benefits may mask deeper ethical questions around the development of the technology and some potentially detrimental impacts. Perhaps one of the clearest instances of such a tension arises over environmental sustainability. This applies particularly to the association with climate change mitigation and the reduction of greenhouse gas emissions.

>Climate change is an issue that lends itself to the „techno-fix“ approach – in other words, it can be tempting to avoid making important changes to our behaviour because we think we can depend on [technology to fix everything](https://journals.sagepub.com/doi/abs/10.1177/0002764201000903). This is known as [the „mitigation obstruction“ argument](https://royalsocietypublishing.org/doi/10.1098/rsta.2014.0062).

>Squaring greenhouse gas emissions with energy demand also raises questions of justice and equity. Energy demand is growing in certain regions, primarily the global south, that have [contributed the least](https://www.sciencedirect.com/science/article/pii/S097308261930777X) to the current climate crisis. Yet fusion programmes are overwhelmingly based [in the global north](https://www.ipp.mpg.de/1740642/weltweit). So if fusion proves viable, those with access to such a transformative technology are not necessarily those who will need it most
