Domestic eco-efficient technologies, such as recycling bins and compact florescent light bulbs, are integral to the eco-modernisation project. To date, however, little research has examined their role in the production of 'sustainable citizens'. In response, this paper explores the productivities of commonplace domestic objects. It draws on qualitative research into a Sydney-based sustainable living programme called 'GreenHome', to examine how participants' environmental ethics became articulated through objects' use. This forges a form of embodied 'techno-ethics' that permeates socio-material relations beyond the (...) immediate. Therefore, this examination of the quotidian deployment of eco-efficient technologies, whilst not denying the problematic nature of technologically-dependant futures, suggests some positive outcomes from individuals' enrolment in domestic eco-modernisation.
