95% of the entire fresh produce range sold by Asda is already at risk from climate change, according to a groundbreaking study by the supermarket giant. The report, which will be published in June, is the first attempt by a food retailer to put hard figures against the impacts global warming will have on the food it buys from across the world. Asda, which is owned by Walmart, brought in consultants PwC to map its entire global fresh produce supply chain against the models being used by the Intergovernmental Panel on Climate Change...Friends of the Earth senior food campaigner, Vicki Hird, welcomed the study and said Asda now needs to act. "Major retailers must wake up to the enormous climate change threat to food supplies – Asda must now put the problem at the core of its business," Hird said. "If they really want to be a greener grocer they must take steps in its marketing strategy, reviewing products which use too much water and steering customers off meat, and in its supply chain, paying producers to cover the cost of sustainable production."
