Companies are increasingly looking for better ways to report on sustainability performance, driven by customer and investor demands. Last month’s COP 21 climate talks in Paris saw more than 100 companies including Ikea, Coca-Cola Enterprises, Walmart, Kellogg and Dell commit to set and report on “science-based emissions targets,” in line with what scientists say is necessary to keep global warming below the threshold of 2 degrees Celsius. And by the end of 2016 a free, global sustainability reporting knowledge platform — the Reporting Exchange — will be available in open beta format.
