This chapter explores the ways in which environmental activists view and negotiate the paradox of using the potentially environmentally damaging technology of computer-mediated communication (CMC). By negotiating the quandaries, many activists are able to resolve their tensions. The different ways in which they do so can be isolated into main tendencies, but such classification illustrates some of the basic diversities between participants of the British environmental movement. The chapter examines the consequences of this negotiation of techno-environmentalism. It begins with an appraisal of the attitudes to technology espoused by environmentalists. The chapter explores their views on CMC and their understandings of the environmental consequences of computer usage. Environmental activists also overcome the apparent contradictions in their use of CMC and their preference for appropriate technology by mitigating the environmentally damaging effects of computer usage.
