Reporting Rate for Supply Chain GHG Emissions, 2009 v. 2010
The percentage of Carbon Disclosure Project Supply Chain members who track and report supply chain emissions more than doubled to 45% in 2010, from 20% in 2009. The survey found that while 72% of members have at least some of their data verified externally, only 39% of suppliers do so, mainly due to high costs associated with this process. Members also struggle to compare the data they get from suppliers, and they are looking for ways to use the data they get to further drive reductions. Compounding these difficulties is the fact that suppliers with multiple customers have difficulties in allocating emissions.
