This document discusses how addressing climate change makes business sense for retailers and other companies. It provides examples of large retailers like Walmart, Carrefour, Tesco, and Ikea committing to reduce their energy use and increase renewable energy to cut costs and improve their brands. The Co-operative Group is highlighted for sourcing 99% of its electricity from renewables, reducing its energy use and packaging, and offsetting carbon for some products. Addressing climate change through energy efficiency saves these companies money while gaining positive publicity.
