Although manufacturers have stepped up their efforts aimed at reducing their own carbon footprints, they have yet to significantly widen those efforts throughout their supply chains. According to a recent study conducted by the Carbon Disclosure Project (CDP) and Accenture, while 43 percent of the respondents say they have achieved year-on-year emissions reductions, only 28 percent of their suppliers can say the same.

Ernst & Young reports that 83 percent of respondents to a recent survey say they are engaging their supply chain in sustainability. In addition to this, 76 percent anticipate natural resource shortages, including water, will affect their core business objectives over the next three to five years, according to the canvass of "corporate sustainability leaders."
