In the context of public and policy concerns about human induced climate change, it is striking that dominant models and histories of English teaching marginalise the environmental significance of English as a school subject (Matthewman, 2010). This is in spite of a growing body of ecocritical work within English and cultural studies which has explored the relationship between cultural texts and environmental thinking (Buell, 2005; Clark, 2011; Garrard, 2012; Glotfelty, 1996; Kerridge & Sammells, 1998). This article explores the potential for teachers in New Zealand to clear the ground for a "greener" version of English. This could be facilitated by a number of features which are unique to the New Zealand context. These include the powerful (though contested) imagery of New Zealand's environmental purity; the historical relationships of New Zealanders to the land; the integration of Maori environmental values into educational policy; the relative openness of the national curriculum in New Zealand; the absence of a dominant canon and tradition of English teaching; and the recent turn towards New Zealand literature (with its strong emphasis on links to the land) in literary choices for study. The article will examine traditions of English in New Zealand against the social, cultural and environmental factors which offer the potential for ecocritical versions of English to emerge within new models of teachers' professional practice.
