Climate change is one of the most critical issues facing business and society. Both the science and the economics are clear: we must act now, or pay a greater price later. Business knows that it must be part of the solution, and is already developing new and innovative ideas, products and processes to cut emissions and create a more resilient economy. And we also know that in tackling the climate challenge there is a huge prize to be won, with the global green market worth £3.4trn.
