Decathlon has committed to reducing its emissions of CO2 sufficiently to help limit the warming of the earth's climate to 1.5 degrees Celsius above pre-industrial levels and ensure a net-zero change after that. In other words, it has joined the #OurOnlyFuture campaign launched by the United Nations and various business leaders, among them Paul Polman, former chief executive of Unilever. In an open letter, the group has called on chief executives to strive to reach the goals in last October's report by the Intergovernmental Panel on Climate Change (IPCC) and set targets through the Science Based Targets initiative (SBTi). These initiatives are designed to achieve a net-zero carbon economy by 2050.
