Purpose – The purpose of this paper is to alert food producers to emerging market demands associated with climate change. Design/methodology/approach – The study draws on literature review and applied market research. Findings – Many food retailers are applying pressure to their value chains to measure and manage carbon emissions. Although consumers play a role, consumers are not the main driver compelling retailers to respond to climate change. Research limitations/implications – This study only interviewed retailers in the United Kingdom and Japan as these are markets that are of particular interest for Australian food exporters. Originality/value – Consumers and retailers in export markets are responding to climate change. The research suggests that food producers may need to consider market signals in addition to regulatory pressure and/or environmental concern when assessing their response to climate change.
