Abstract This article argues that technology should be considered to be among the structures of environmental injustice. Explaining that technology can be inherently just or unjust—that is, that the material artifacts that comprise technological infrastructures can be more or less compatible with environmentally just social arrangements—it suggests that most existing technology is relatively incompatible with environmental justice. It then offers a list of design features that would help make technology inherently more compatible with fair distribution of environmental risks and benefits, equitable enforcement of protective environmental regulations, the ability of marginalized communities to build social and economic capacity, and meaningful public participation in environmental decision making. Recognizing the role that technological design plays in structuring environmental injustice should help environmental justice practitioners recognize and advocate for technology compatible with a just world.
