This resource from the Pew Center for Global Change's Website is a publication dealing with how leading industrial firms inventory and verify their greenhouse gas (GHG) emissions. Most corporations are interested in reducing GHG output and are monitoring their emissions, but the next step is to have third-party verification of their GHG output and reduction. This new report, intended to guide corporation managers, covers the experiences of individual firms and their stakeholders, suggests how to improve the inventory process and the reliability of reported information, and reviews approaches to verification by government- and non-government-sponsored programs for greenhouse emissions reduction. The lead author is Christopher P. Loreti, a Senior Manager in the Global Environment and Risk practice of Arthur D. Little, Inc. The 52-page text can be downloaded as a .pdf, .zip, or .sit file.
