Leading companies are starting to monitor everything from a camel’s yearly methane emissions to light bulb efficiencies amid growing pressure to demonstrate the environmental credentials of their suppliers. Almost 40 per cent of multinational companies who took part in a new study of how businesses are handling the carbon emissions of their suppliers said they were now taking action on the issue...Only 7 per cent were actively ditching suppliers who failed to meet emissions criteria. But almost 60 per cent claimed they would be prepared to pay a premium for environmentally sensitive suppliers in future...“Responsibility for carbon stewardship falls to CEOs and the board,” [Hugh Jones, managing director of the Carbon Trust Advisory team] said. “But going forward, as carbon becomes more widely understood as a commodity, there will be increasing pressure from external sources, particularly shareholders, to make companies address the carbon intensive area of supply chain emissions.” [refers to Marshalls, BT]
