GHG Protocol Corporate Standard

The GHG Protocol Corporate Standard (GHG Protocol Corporate Accounting and Reporting Standard, GHGPCS) is an initiative for the global standardisation of emission of Greenhouse Gases in order that corporate entities should measure, quantify, and provide reportage of their own emission levels so that global emissions are made manageable. The relevant gases, as described by the 11 December 1997 Kyoto Protocol, that was implemented 16 February 2005, are: carbon dioxide, hydrofluorocarbons, methane, nitrous oxide, nitrogen trifluoride, perfluorocarbons  and sulphur hexafluoride. The protocol itself is under the management of the World Resources Institute and the World Business Council for Sustainable Development. The GHGP was launched in 1998 and introduced in 2001.
