A survey of alumni of two longstanding interdisciplinary secondary school environmental studies programs revealed that the vast majority of alumni reported being engaged in pro-environmental behaviours, which they attributed to participation in the programs five to twenty-three years prior. That finding in itself is worth sharing. Digging deeper, however, revealed that most reported behaviours were in the private rather than public sphere. Women alumni reported engaging in more household and marketplace-oriented behaviours. Further, a small number of men from the rural school expressed hostility towards environmental concerns using aggressively sexist and homophobic discourse. A feminist analysis takes into account structural forces such as patriarchy and neoliberalism to interpret the findings and illuminates gendered dimensions of pro- and anti-environmental behaviours.
