Issues of global justice are ethical concerns for decision-making procedures in wealthy countries of the globe. Many arrangements and technological developments can influence just relations with other regions that are less prosperous. The paper points towards resource exploitation as a common cause for global injustices. Many of the resources extracted in less industrialised and wealthy regions are pertinent for a social transformation for sustainability, e.g. rare earths mined in order to provide electric mobility for a sustainable transition. The paper highlights that sometimes technological strategies in decision-making settings that are relevant to a social transformation for sustainability in wealthy regions have serious discursive effects which have not gained enough attention in the debate. In particular, it is argued that the objection of technosolutionism has not been sufficiently addressed in this regard. This is a critique against societal solution strategies for demanding challenges which would also allow less technologically advanced options. A novel reading of this objection is introduced that allows for a more concrete connection between technological options and global justice issues. Overall, the paper argues for a specific connection between (1) the objection of technosolutionism, (2) social transformation for environmental sustainability, and (3) the practice of resource exploitation. If technological options have a tendency to crowd out other non- or low-technological options in decision-making processes and if global justice problems are more connected to technological options, then there are ethical reasons to object to technosolutionism in this regard.
